Why might we need **Sharding/Partitioning** for the ETS tables? The main reason
is to keep the lock contention under control enabling ETS tables to scale out
and support higher levels of concurrency without lock issues; specially
write-locks, which most of the cases might cause significant performance
degradation.
Therefore, one of the most common and proven strategies to deal with these
problems is [Sharding](https://en.wikipedia.org/wiki/Shard_(database_architecture)) or [Partitioning](https://en.wikipedia.org/wiki/Partition_(database)); the principle
is pretty similar to [DHTs](https://en.wikipedia.org/wiki/Distributed_hash_table).
This is where [shards](https://hexdocs.pm/shards/shards.html) comes in. [Shards](https://hexdocs.pm/shards/shards.html) is an Erlang/Elixir
library fully compatible with the [ETS API](http://erlang.org/doc/man/ets.html), but it implements sharding
or partitioning on top of the ETS tables, completely transparent and out-of-box.
See the **[getting started](https://hexdocs.pm/shards/getting-started.html)** guide
and the **[online documentation](https://hexdocs.pm/shards/)**.

```
You can find tests results in `_build/test/logs`, and coverage in
`_build/test/cover`.
> **NOTE:** `shards` comes with a helper `Makefile`, but it is just a simple
> wrapper on top of `rebar3`, therefore, you can do everything using `rebar3`
> directly as well (e.g.: `rebar3 do ct, cover`).

(shards v1.1.0)
===============================================================================================================================
Partitioned/Sharded ETS tables.
[features](#module-features)
Features
---------------------------------------
* `shards` implements the ETS API to keep compatibility and make the usage straightforward; exactly the same if you were using `ets`.
* Sharded or partitioned tables under-the-hood. This feature is managed entirely by `shards` and it is 100% transparent for the client. Provides a logical view of a single ETS table, but internally, it is composed by `N` number of `partitions` and each partition has associated an ETS table.
* High performance and scalability. `shards` keeps the lock contention under control enabling ETS tables to scale out and support higher levels of concurrency without lock issues; specially write-locks, which most of the cases might cause significant performance degradation.
[partitioned-table](#module-partitioned-table)
Partitioned Table
------------------------------------------------------------------
When a table is created with `shards:new/2`, a new supervision tree is created to represent the partitioned table. There is a main supervisor `shards_partition_sup` that create an ETS table to store the metadata and also starts the children which are the partitions to create. Each partition is owned by `shards_partition` (it is a `gen_server`) and it creates an ETS table for storing data mapped to that partition. The supervision tree looks like:
```
[shards\_partition]--><ETS-Table>
/
[shards\_partition\_sup]--<-[shards\_partition]--><ETS-Table>
| \
<Metadata-ETS-Table> [shards\_partition]--><ETS-Table>
```
The returned value by `shards:new/2` may be an atom if it is a named table or a reference otherwise, and in the second case the returned reference is the one of the metadata table, which is the main entry point and it is owned by the main supervisor. See `shards:new/2` for more information.
[usage](#module-usage)
Usage
------------------------------
```
> Tab = shards:new(tab, []).
#Ref<0.1541908042.2337144842.31535>
> shards:insert(Tab, [{a, 1}, {b, 2}, {c, 3}]).
true
> shards:lookup(Tab, a).
[{a,1}]
> shards:lookup(Tab, b).
[{b,2}]
> shards:lookup(Tab, c).
[{c,3}]
> shards:lookup\_element(Tab, c, 2).
3
> shards:lookup(Tab, d).
[]
> shards:delete(Tab, c).
true
> shards:lookup(Tab, c).
[]
```
As you can see, the usage is exactly the same if you were using `ets`, you can try the rest of the ETS API but with `shards` module.
[important](#module-important)
Important
------------------------------------------
Despite `shards` aims to keep 100% compatibility with current ETS API, the semantic for some of the functions may be a bit different due to the nature of sharding; it is not the same having all the entries in a single table than distributed across multiple ones. For example, for query-based functions like `select`, `match`, etc., the returned entries are the same but not necessary the same order than `ets`. For `first`, `next`, and `last` they behave the similar in the sense by means of them a partitioned table is traversed, so the final result is the same, but the order in which the entries are traversed may be different. Therefore, it is highly recommended to read the documentation of the functions.

Despite this functions behaves exactly the same as `ets:insert_new/2` and produces the same result, there is a big difference due to the nature of the sharding distribution model, **IT IS NOT ATOMIC**. Opposite to `shards:insert/2`, this function tries to roll-back previous inserts execution on other partitions if it fails by inserting an object at some partition, but there might be race conditions during roll-back execution.

new(Name, Options)
==================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards.erl#L944 "View Source")
```
-spec new(Name, Options) -> Tab when Name :: atom(), Options :: [[option](#t:option/0)()], Tab :: [tab](#t:tab/0)().
```
This operation is equivalent to `ets:new/2`, but when is called, instead of create a single ETS table, it creates a new supervision tree for the partitioned table.
The supervision tree is composed by a main supervisor `shards_partition_sup` and `N` number of workers or partitions handled by `shards_partition` (partition owner). Each worker creates an ETS table to handle the partition. Also, the main supervisor `shards_partition_sup` creates an ETS table to keep the metadata for the partitioned table.
Returns an atom if the created table is a named table, otherwise, a reference is returned. In the last case, the returned reference is the one of the metadata table, which is the main entry-point and it is owned by the main supervisor `shards_partition_sup`.
###
[options](#new/2-options)
Options:
In addition to the options given by `ets:new/2`, this functions provides the next options:* `{partitions, N}` - Specifies the number of partitions for the sharded table. By default, `N = erlang:system_info(schedulers_online)`.
* `{keyslot_fun, F}` - Specifies the function used to compute the partition where the action will be evaluated. Defaults to `erlang:phash2/2`.
* `{parallel, P}` - Specifies whether `shards` should work in parallel mode or not, for the applicable functions, e.g.: `select`, `match`, etc. By default is set to `false`.
* `{parallel_timeout, T}` - When `parallel` is set to `true`, it specifies the max timeout for a parallel execution. Defaults to `infinity`.
###
[access](#new/2-access)
Access:
Currently, only `public` access is supported by `shards:new/2`. Since a partitioned table is started with its own supervision tree when created, it is very tricky to provide `private` or `protected` access since there are multiple partitions (or ETS tables) and they are owned by the supervisor's children, and the supervisor along with their children (or partitions) are managed by `shards` under-the-hood; it is completely transparent for the client.
###

[Functions](#functions)
------------------------
[map(Fun, Enumerable)](#map/2)
Returns a list where each element is the result of invoking `Fun` on each corresponding element of `Enumerable`.
[pmap(Fun, Enumerable)](#pmap/2)
Equivalent to [pmap(Fun, infinity, Enumerable)](#pmap/3).
[pmap(Fun, Timeout, Enumerable)](#pmap/3)
Similar to `shards_enum:map/2` but it runs in parallel.
[reduce(Fun, Acc0, Enumerable)](#reduce/3)
Invokes `Fun` for each element in the `Enumerable` with the accumulator.
[reduce\_while(Fun, Acc0, Enumerable)](#reduce_while/3)
Reduces enumerable until `Fun` returns `{halt, AccOut}`.

map(Fun, Enumerable)
====================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards_enum.erl#L34 "View Source")
```
-spec map(Fun, Enumerable) -> [Result]
when
Fun :: fun((Elem) -> Result),
Elem :: term(),
Result :: term(),
Enumerable :: [term()] | map() | non_neg_integer().
```
Returns a list where each element is the result of invoking `Fun` on each corresponding element of `Enumerable`.
For maps, the function expects a key-value tuple.

pmap(Fun, Enumerable)
=====================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards_enum.erl#L151 "View Source")
Equivalent to [pmap(Fun, infinity, Enumerable)](#pmap/3).

pmap(Fun, Timeout, Enumerable)
==============================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards_enum.erl#L163 "View Source")
```
-spec pmap(Fun, Timeout, Enumerable) -> [Result]
when
Fun :: fun((Elem) -> Result),
Elem :: term(),
Timeout :: timeout(),
Result :: term(),
Enumerable :: [term()] | map() | non_neg_integer().
```
Similar to `shards_enum:map/2` but it runs in parallel.
[Link to this function](#reduce/3 "Link to this function")
reduce(Fun, Acc0, Enumerable)
=============================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards_enum.erl#L70 "View Source")
```
-spec reduce(Fun, Acc0, Enumerable) -> Acc1
when
Fun :: fun((Elem, AccIn) -> AccOut),
Elem :: term(),
AccIn :: term(),
AccOut :: term(),
Acc0 :: term(),
Acc1 :: term(),
Enumerable :: [term()] | map() | non_neg_integer().
```
Invokes `Fun` for each element in the `Enumerable` with the accumulator.
The initial value of the accumulator is `Acc0`. The function is invoked for each element in the enumerable with the accumulator. The result returned by the function is used as the accumulator for the next iteration. The function returns the last accumulator.
[Link to this function](#reduce_while/3 "Link to this function")
reduce\_while(Fun, Acc0, Enumerable)
====================================
[View Source](https://github.com/cabol/shards/blob/v1.1.0/src/shards_enum.erl#L116 "View Source")
```
-spec reduce_while(Fun, Acc0, Enumerable) -> Acc1
when
Fun :: fun((Elem, AccIn) -> FunRes),
FunRes :: {cont | halt, AccOut},
Elem :: term(),
AccIn :: term(),
AccOut :: term(),
Acc0 :: term(),
Acc1 :: term(),
Enumerable :: [term()] | map() | non_neg_integer().
```
Reduces enumerable until `Fun` returns `{halt, AccOut}`.
The return value for `Fun` is expected to be
* `{cont, AccOut}` to continue the reduction with `AccOut` as the new accumulator or
* `{halt, AccOut}` to halt the reduction
If fun returns `{halt, AccOut}` the reduction is halted and the function returns `AccOut`. Otherwise, if the enumerable is exhausted, the function returns the accumulator of the last `{cont, AccOut}`.

shards\_group
(shards v1.1.0)
============================================================================================================================================
This module provides a dynamic supervisor for creating and/or deleting tables dynamically in runtime and as part of an existing supervision tree; any application supervision tree using `shards`.
[usage](#module-usage)
Usage
------------------------------
To use `shards` and make the creates tables part of your application supervision tree, you have to add to your main supervisor:
```
% Supervisor init callback
init(GroupName) ->
Children = [
shards\_group:child\_spec(GroupName)
],
{ok, {{one\_for\_one, 10, 10}, Children}}.
```
After your application starts, you can create and delete tables like so:
```
> {ok, Pid, Tab} = shards\_group:new\_table(GroupName, mytab, [named\_table]).
{ok,<0.194.0>,#Ref<0.3052443831.2753691659.260835>}
> shards\_group:del\_table(GroupName, mytab).
ok

shards\_meta
(shards v1.1.0)
==========================================================================================================================================
This module encapsulates the partitioned table metadata.
Different properties must be stored somewhere so `shards` can work properly. Shards perform logic on top of ETS tables, for example, compute the partition based on the `Key` where the action will be applied. To do so, it needs the number of partitions, the function to select the partition, and also the partition identifier to perform the ETS action.

In this guide, we're going to learn some basics about `shards`, how to create
partitioned tables and how to use them; which is the easiest part, since
it is the same ETS API.

Creating partitioned tables
-----------------------------------------------------------------------------------------
Exactly as ETS, `shards:new/2` function receives 2 arguments, the name of the
table and the options. But in addition to the options given by `ets:new/2`,
`shards` provides the next ones:
* `{partitions, pos_integer()}` - Allows to set the desired number of
partitions. By default, the number of partitions is the total of online
schedulers (`erlang:system_info(schedulers_online)`).
* `{keyslot_fun, shards_meta:keyslot_fun()}` - Function used to compute the
partition where the action will be evaluated based on the key. Defaults to
`erlang:phash2/2`.
* `{parallel, boolean()}` - Specifies whether `shards` should work in parallel
mode or not, for the applicable functions, e.g.: `select`, `match`, etc. By
default is set to `false`.
* `{parallel_timeout, timeout()}` - When `parallel` is set to `true`, it
specifies the max timeout for a parallel execution. Defaults to `infinity`.
Wen a new table is created, the [metadata](https://github.com/cabol/shards/blob/master/src/shards_meta.erl) is created for that
table as well. The purpose of the **metadata** is to store information related
to that table, such as: number of partitions, keyslot function, etc. To learn
more about it, check out [shards\_meta](https://github.com/cabol/shards/blob/master/src/shards_meta.erl).
**Erlang:**
```
% create a named table with 4 shards
> shards:new(tab1, [named\_table, {partitions, 4}]).
tab1
% create another one with default options
> shards:new(tab2, []).
#Ref<0.893853601.1266286595.53859>

#Reference<0.1257361217.1909325839.17166>

As you may have noticed using `shards` is extremely easy, it's only matters of
using the same ETS API but with `shards` module.
You can try the rest of the ETS API but using `shards`.
[making-partitioned-tables-part-of-an-application-s-supervision-tree](#making-partitioned-tables-part-of-an-application-s-supervision-tree)
Making partitioned tables part of an application's supervision tree
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There might be some cases we may want to start the tables as part of an
existing supervision tree. To do so, we can create a dynamic supervisor
for taking care of creating/deleting the tables and add the dynamic
supervisor as part of our app supervision tree.
Shards provides the module `shards_group`, which is a dynamic supervisor that
can bee added to an existing application and/or supervision tree. Besides,
`shards_group` brings with the function to create tables making them part of
the dynamic supervisor and also with the function to delete them and remove
them from the dynamic supervisor. But let's see how it works!
###
[erlang-example](#erlang-example)
Erlang example
Supposing you have an application `myapp` and the main supervisor `myapp_sup`,
the only piece of configuration is to setup the `shards_group` as a supervisor
within the application's supervision tree, like so:
```
-module(myapp\_sup).
-export([start\_link/1, init/1]).
start\_link() ->
supervisor:start\_link({name, ?MODULE}, ?MODULE, []).
init(\_) ->
Children = [
% Dynamic supervisor with default name shards\_group
% See shards\_group:child\_spec/1
shards\_group:child\_spec()
],
{ok, {{one\_for\_one, 10, 10}, Children}}.
```
> The call `shards_group:child_spec()` will return the spec using the default
> name for the dynamic supervisor `shards_group`, but can pass the desired name
> by calling `shards_group:child_spec(desired_name)`.
>
>
Once the app is started, you can use `shards_group` to create/delete tables
and `shards` for the rest of the API functions, like so:
```
% create a table as part of the app supervision tree
> shards\_group:new\_table(myapp\_dynamic\_sup, tab1, [named\_table]).
{ok,<0.194.0>,#Ref<0.3052443831.2753691659.260835>}
> shards:insert(tab1, [{a, 1}, {b, 2}]).
true
> shards:lookup\_element(tab1, a, 2).
1
% let's create another table
> {ok, \_Pid, Tab} = shards\_group:new\_table(myapp\_dynamic\_sup, tab2, []).
{ok,<0.195.0>,#Ref<0.3052443831.2753691659.260836>}
> shards:insert(tab2, [{c, 3}, {d, 4}]).
true
> shards:lookup\_element(tab1, c, 2).
3
% you can open the observer to see hoe the tables look like
> observer:start().
ok
% deleting a table
> shards\_group:del\_table(myapp\_dynamic\_sup, tab1).
true
```
###
[elixir-example](#elixir-example)
Elixir example
In Elixir is much easier it provides the [`DynamicSupervisor`](https://hexdocs.pm/elixir/DynamicSupervisor.html) module out-of-box,
so we have two options, either use `:shards_group` like before in the Erlang
example, or use [`DynamicSupervisor`](https://hexdocs.pm/elixir/DynamicSupervisor.html) and create a simple module to encapsulate
the logic of creating/deleting tables. Since we already know how `:shards_group`
works in the previous example, let's take the second option.
First of all, let's create the module to encapsulate the logic of creating and
deleting the tables:
```
defmodule MyApp.DynamicShards do
@moduledoc false
# creates a table with shards as part of the DynamicSupervisor which at
# the same time is part of the app supervision tree
def new(name, opts) do
{:ok, \_pid, tab} =
DynamicSupervisor.start\_child(\_\_MODULE\_\_, table\_spec(name, opts))
tab
end
# deletes the table and also removes the table supervisor from the
# DynamicSupervisor
def delete(tab) do
DynamicSupervisor.terminate\_child(\_\_MODULE\_\_, :shards\_meta.tab\_pid(tab))
end
# this functions encapsulates the logic of creating the sharded table
# as child of the DynamicSupervisor
def start\_table(name, opts) do
tab = :shards.new(name, opts)
pid = :shards\_meta.tab\_pid(tab)
{:ok, pid, tab}
end
# DynamicSupervisor child spec
defp table\_spec(name, opts) do
%{
id: name,
start: {\_\_MODULE\_\_, :start\_table, [name, opts]},
type: :supervisor
}
end
end
```
The final piece of configuration is to setup a [`DynamicSupervisor`](https://hexdocs.pm/elixir/DynamicSupervisor.html) as a
supervisor within the application's supervision tree, which we can do in
`lib/my_app/application.ex`, inside the `start/2` function:
```
def start(\_type, \_args) do
children = [
{DynamicSupervisor, strategy: :one\_for\_one, name: MyApp.DynamicShards}
]
...
```
Now we can use `:shards`:
```
iex> MyApp.DynamicShards.new(:t1, [:named\_table])
:t1
iex> t2 = MyApp.DynamicShards.new(:t2, [])
#Reference<0.2506606486.3592028173.65798>
iex> :shards.insert(:t1, a: 1, b: 2)
true
iex> :shards.insert(t2, c: 3, d: 4)
true
iex> :shards.lookup\_element(:t1, :a, 2)
1
iex> :shards.lookup\_element(t2, :c, 2)
3
# open the observer
iex> :observer.start()
ok
# delete a table
iex> MyApp.DynamicShards.delete(:t1)
:ok
```

Storing and retrieving custom metadata entries
--------------------------------------------------------------------------------------------------------------------------------------------------
Since `shards` uses an internal ETS table for the metadata, it also provides
helper functions for storing and retrieving custom metadata entries.
```
> Tab = shards:new(mytab, [named\_table, {partitions, 4}]).
mytab
> shards:put\_meta(Tab, foo, bar).
ok
> shards:get\_meta(Tab, foo).
bar
% Non-existing key
> shards:get\_meta(Tab, foo\_foo).
undefined
% With default
> shards:get\_meta(Tab, foo\_foo, bar\_bar).
bar\_bar
```
**Elixir:**
```
iex> tab = :shards.new(:mytab, [:named\_table, partitions: 4])
:mytab
iex> :shards.put\_meta(tab, "foo", "bar")
:ok
iex> :shards.get\_meta(tab, "foo")
"bar"
# Non-existing key
iex> :shards.get\_meta(tab, "foo foo")
:undefined
# With default
iex> :shards.get\_meta(tab, "foo foo", "bar bar")
"bar bar"
```
###
[caching-the-metadata](#caching-the-metadata)
Caching the metadata
Like it is explained in [shards module](https://hexdocs.pm/shards/shards.html),
when a partitioned table is created there is a metadata associated to it, to
resolve the number of partitions and other needed attributes. Hence, every time
a function is executed, `shards` has to resolve the metadata first; but this is
done internally by `shards`. Nevertheless, `shards` allows to pass the metadata
as last argument for most of the functions (check the docs to see what functions
allow it), in case you are able to cache it and use it later for further
operations. This is possible because the metadata is something doesn't change,
so it can be easily cached and avoid `shards` the extra step to retrieve it
from the meta table. But be aware this is just an ETS lookup, so the improvement
is terms of performance may be insignificant, for that reason it is
recommendable to evaluate very carefully each scenario and and see if its really
worth it.
> The overall recommendation is to let `shards` take care of retrieving the
> metadata and everything else, just use the base `shards` API (ETS API).
>
>
In case you want to cache the metadata:
**Erlang:**
```
> Tab = shards:new(mytab, [named\_table, {partitions, 4}]).
mytab
> Meta = shards:table\_meta(Tab).
{meta,<0.174.0>,1,4,fun erlang:phash2/2,false,[named\_table]}
```
**Elixir:**
```
iex> tab = :shards.new(:mytab, [:named\_table, partitions: 4])
:mytab
iex> meta = :shards.meta(tab)
{:meta, #PID<0.163.0>, 1, 4, &:erlang.phash2/2, false, [:named\_table]}
```
Then, you can use it for most of the functions (check the docs):
**Erlang:**
```
> shards:insert(Tab, [{a, 1}, {b, 2}], Meta).
true
> shards:lookup(Tab, a, Meta).
[{a,1}]
> shards:lookup\_element(Tab, a, 2, Meta).
1
```
**Elixir:**
```
iex> :shards.insert(tab, [a: 1, b: 2], meta)
true
iex> :shards.lookup(tab, :a, meta)
[a: 1]
iex> :shards.lookup\_element(tab, :a, 2, meta)
1
```
> **NOTE:** See [shards](https://hexdocs.pm/shards/shards.html) docs for more
> information about the functions that support receiving the metadata; most of
> them allow the metadata parameter, but there are few exceptions you should
> know.

:lock: Vaultex β vaultex v1.0.1
try { if(localStorage.getItem('night-mode') === 'true') document.body.className += ' night-mode'; } catch (e) { }
:lock: Vaultex
==============
[](https://hex.pm/packages/vaultex)
[](https://hex.pm/packages/vaultex)
A very simple elixir client that authenticates, reads, writes, and deletes
secrets from HashiCorp's Vault. As listed on [Vault
Libraries](https://www.vaultproject.io/api/libraries.html#elixir).
Installation
---------------
The package can be installed as:
1) Add `vaultex` to your list of dependencies in `mix.exs`:
```
def deps do
[{:vaultex, "~> 0.8"}]
end
```
2) Ensure `vaultex` is started before your application:
```
def application do
[applications: [:vaultex]]
end
```
Configuration
----------------
You can configure your vault endpoint with a single environment variable:
* `VAULT_ADDR`
Or a single application variable:
* `:vaultex, :vault_addr`
An example value for `VAULT_ADDR` is `http://127.0.0.1:8200`.
Alternatively the vault endpoint can be specified with environment variables:
* `VAULT_HOST`
* `VAULT_PORT`
* `VAULT_SCHEME`
Or application variables:
* `:vaultex, :host`
* `:vaultex, :port`
* `:vaultex, :scheme`
These default to `localhost`, `8200`, `http` respectively.
You can skip SSL certificate verification with `:vaultex, vault_ssl_verify: true` option or `VAULT_SSL_VERIFY=true` environment variable.
If you do want to use SSL verification, set the `VAULT_CACERT` environment
variable to the SSL certificate location. (See the [Vault
documentaion](https://www.vaultproject.io/docs/commands/#vault_cacert) for more
details.)
Usages
---------
To read a secret you must provide the path to the secret and the authentication
backend and credentials you will use to login. See the
[Vaultex.Client.auth/2](https://hexdocs.pm/vaultex/Vaultex.Client.html#auth/2)
docs for supported auth backends.
Authenticate to different authentication backends.
```
iex> Vaultex.Client.auth(:app\_id, {app\_id, user\_id})
iex> Vaultex.Client.auth(:userpass, {username, password})
iex> Vaultex.Client.auth(:ldap, {username, password})
iex> Vaultex.Client.auth(:github, {github\_token})
iex> Vaultex.Client.auth(:approle, {role\_id, secret\_id})
iex> Vaultex.Client.auth(:token, {token})
iex> Vaultex.Client.auth(:kubernetes, %{jwt: "jwt", role: "role"})
iex> Vaultex.Client.auth(:radius, %{username: "user", password: "password"})
iex> Vaultex.Client.auth(:aws\_iam, {role, server})
```
Reading secret from authenticated backends.
```
iex> Vaultex.Client.read "secret/bar", :github, {github\_token}
{:ok, %{"value" => bar"}}
iex> Vaultex.Client.read\_dynamic "secret/dynamic/bar", :github, {github\_token}
{:ok,
%{
"data" => %{"value" => "bar"},
"lease\_duration" => 60,
"lease\_id" => "secret/dynamic/foo/b4z",
"renewable" => true
}}
```
Additional actions on the secret.
```
iex> Vaultex.Client.renew\_lease("secret/dynamic/foo/b4z", 100, :github, {github\_token})
{:ok,
%{
"lease\_id" => "secret/dynamic/foo/b4z",
"lease\_duration" => 160,
"renewable" => true
}}
iex> Vaultex.Client.write "secret/foo", %{"value" => "bar"}, :app\_id, {app\_id, user\_id}
iex> Vaultex.Client.delete "secret/foo", :app\_id, {app\_id, user\_id}
```
Notes for `aws_iam` method
-----------------------------
The AWS IAM authentication method requires you to have
[ExAws](https://github.com/ex-aws/ex_aws) installed as a dependency and
correctly configured. No additional ExAws modules are required. For more
details see the [Vault AWS
docs](https://www.vaultproject.io/docs/auth/aws.html).
* If `role` id set to `nil` Vault will try to infer the vault role to use.
* `server` may be set to `nil` or to the value to pass in the
`X-Vault-AWS-IAM-Server-ID` header.
Releasing
------------
To release you need to bump the version and add some changes to the change log,
you can do this with:
```
mix eliver.bump
```

Hammer.Backend.Redis
(hammer\_backend\_redis v6.1.2)
==========================================================================================================================================================================================
Documentation for Hammer.Backend.Redis
This backend uses the [Redix](https://hex.pm/packages/redix) library to connect to Redis.
The backend process is started by calling `start_link`:
```
Hammer.Backend.Redis.start\_link(
expiry\_ms: 60\_000 \* 10,
redix\_config: [host: "example.com", port: 5050]
)
```
Options are:
* `expiry_ms`: Expiry time of buckets in milliseconds,
used to set TTL on Redis keys. This configuration is mandatory.
* `redix_config`: Keyword list of options to the [`Redix`](https://hexdocs.pm/redix/1.2.0/Redix.html) redis client,
also aliased to `redis_config`
* `redis_url`: String url of redis server to connect to
(optional, invokes Redix.start\_link/2)

Overview
=====================================================================================================================================
A Redis backend for the Hammer rate-limiter
[Hammer](https://github.com/ExHammer/hammer) is a rate-limiter for
the [Elixir](https://elixir-lang.org/) language. It's killer feature is a
pluggable backend system, allowing you to use whichever storage suits your
needs.
This package provides a Redis backend for Hammer, using
the [Redix](https://github.com/whatyouhide/redix) library to connect to the
Redis server.
To get started, read
the [Hammer Tutorial](https://hexdocs.pm/hammer/tutorial.html) first, then add
the `hammer_backend_redis` dependency:
```
def deps do
[{:hammer\_backend\_redis, "~> 6.1"},
{:hammer, "~> 6.0"}]
end
```
... then configure the `:hammer` application to use the Redis backend:
```
config :hammer,
backend: {Hammer.Backend.Redis, [expiry\_ms: 60\_000 \* 60 \* 2,
redix\_config: [host: "some.host"]]}
```
(the `redix_config` arg is a keyword-list which is passed to Redix, it's also
aliased to `redis_config`, with an `s`)
And that's it, calls to [`Hammer.check_rate/3`](https://hexdocs.pm/hammer/6.1.0/Hammer.html#check_rate/3) and so on will use Redis to store
the rate-limit counters.

Buffy
(Buffy v2.0.0)
=========================================================================================================================
Buffy is broken down into different modules depending on how you want to
handle your function calling.
[Throttle](#module-throttle)
-----------------------------
The [`Buffy.Throttle`](Buffy.Throttle.html) module will wait for a specified amount of time before
invoking the function. If the function is called again before the time has
elapsed, it's a no-op. Once the timer has expired, the function will be called,
and any subsequent calls will start a new timer.

First function invocation
```
[Example Usage](#module-example-usage)
---------------------------------------
You'll first need to create a module that will be used to throttle.
```
defmodule MyTask do
use Buffy.Throttle,
throttle: :timer.minutes(2)
def handle\_throttle(args) do
# Do something with args
end
end
```
Next, you can use the `throttle/1` function with the registered module.
```
iex> MyTask.throttle(args)
:ok
```
[Options](#module-options)
---------------------------
* `:registry_module` (`atom`) - Optional. A module that implements the [`Registry`](https://hexdocs.pm/elixir/Registry.html) behaviour. If you are running in a distributed instance, you can set this value to `Horde.Registry`. Defaults to [`Registry`](https://hexdocs.pm/elixir/Registry.html).
* `:registry_name` (`atom`) - Optional. The name of the registry to use. Defaults to the built in Buffy registry, but if you are running in a distributed instance you can set this value to a named `Horde.Registry` process. Defaults to `Buffy.Registry`.
* `:restart` (`:permanent` | `:temporary` | `:transient`) - Optional. The restart strategy to use for the GenServer. Defaults to `:temporary`.
* `:supervisor_module` (`atom`) - Optional. A module that implements the [`DynamicSupervisor`](https://hexdocs.pm/elixir/DynamicSupervisor.html) behaviour. If you are running in a distributed instance, you can set this value to `Horde.DynamicSupervisor`. Defaults to [`DynamicSupervisor`](https://hexdocs.pm/elixir/DynamicSupervisor.html).
* `:supervisor_name` (`atom`) - Optional. The name of the dynamic supervisor to use. Defaults to the built in Buffy dynamic supervisor, but if you are running in a distributed instance you can set this value to a named `Horde.DynamicSupervisor` process. Defaults to `Buffy.DynamicSupervisor`.
* :throttle (`non_neg_integer`) - Required. The amount of time to wait before invoking the function. This value is in milliseconds.
[Using with Horde](#module-using-with-horde)
---------------------------------------------
If you are running Elixir in a cluster, you can utilize `Horde` to only run one of your throttled functions at a time. To do this, you'll need to set the `:registry_module` and `:supervisor_module` options to `Horde.Registry` and `Horde.DynamicSupervisor` respectively. You'll also need to set the `:registry_name` and `:supervisor_name` options to the name of the Horde registry and dynamic supervisor you want to use.
```
defmodule MyThrottler do
use Buffy.Throttle,
registry\_module: Horde.Registry,
registry\_name: MyApp.HordeRegistry,
supervisor\_module: Horde.DynamicSupervisor,
supervisor\_name: MyApp.HordeDynamicSupervisor,
throttle: :timer.minutes(2)
def handle\_throttle(args) do
# Do something with args
end
end
```
[Telemetry](#module-telemetry)
-------------------------------
These are the events that are called by the [`Buffy.Throttle`](Buffy.Throttle.html#content) module:
* `[:buffy, :throttle, :throttle]` - Emitted when the `throttle/1` function is called.
* `[:buffy, :throttle, :handle, :start]` - Emitted at the start of the `handle_throttle/1` function.
* `[:buffy, :throttle, :handle, :stop]` - Emitted at the end of the `handle_throttle/1` function.
* `[:buffy, :throttle, :handle, :exception]` - Emitted when an error is raised in the `handle_throttle/1` function.
All of these events will have the following metadata:
* `:args` - The arguments passed to the `throttle/1` function.
* `:key` - A hash of the passed arguments used to deduplicate the throttled function.
* `:module` - The module using [`Buffy.Throttle`](Buffy.Throttle.html#content).
With the additional metadata for `[:buffy, :throttle, :handle, :stop]`:
* `:result` - The return value of the `handle_throttle/1` function.
[Summary](#summary)

[state()](#t:state/0)
Internal state that [`Buffy.Throttle`](Buffy.Throttle.html#content) keeps.
[Callbacks](#callbacks)
------------------------
[handle\_throttle(args)](#c:handle_throttle/1)
The function called after the throttle has completed. This function will
receive the arguments passed to the `throttle/1` function.

OpentelemetryPhoenix
(Opentelemetry Phoenix v1.1.1)
============================================================================================================================================================================================================================================
OpentelemetryPhoenix uses [telemetry](https://hexdocs.pm/telemetry/) handlers to create [`OpenTelemetry`](https://hexdocs.pm/opentelemetry_api/1.1.1/OpenTelemetry.html) spans.
Current events which are supported include endpoint start/stop, router start/stop,
and router exceptions.
###
[supported-options](#module-supported-options)
Supported options
* `:endpoint_prefix` (list of [`atom/0`](https://hexdocs.pm/elixir/typespecs.html#basic-types)) - The endpoint prefix in your endpoint. The default value is `[:phoenix, :endpoint]`.
* `:adapter` - The phoenix server adapter being used. The default value is `nil`.
If you are using PlugCowboy as your adapter you can add `:opentelemetry_cowboy` to your project
and pass the `:adapter` option when calling setup. Setting this option will prevent a new
span from being started and the existing cowboy span to be continued. This is the recommended
setup for measuring accurate latencies.
`Bandit.PhoenixAdapter` is not currently supported.
[usage](#module-usage)
Usage
------------------------------
In your application start:
```
def start(\_type, \_args) do
:opentelemetry\_cowboy.setup()

NervesSSH
=========================================================================================================================
[](https://circleci.com/gh/nerves-project/nerves_ssh/tree/main)
[](https://hex.pm/packages/nerves_ssh)
Manage an SSH daemon and its subsystems on Nerves devices. It has the following
features:
1. Automatic startup of the SSH daemon on initialization
2. Ability to hook the SSH daemon into a supervision tree of your choosing
3. Easy setup of SSH firmware updates for Nerves
4. Easy shell and exec setup for Erlang, Elixir, and LFE
5. Some protection from easy-to-make mistakes that would cause ssh to not be
available
[Usage](#usage)
----------------
This library wraps Erlang/OTP's [SSH
daemon](http://erlang.org/doc/man/ssh.html#daemon-1) to make it easier to use
reliably with Nerves devices.
Most importantly, it makes it possible to segment failures in other OTP
applications from terminating the daemon and it recovers from rare scenarios
where the daemon terminates without automatically restarting.
It can be started automatically as an OTP application or hooked into a
supervision tree of your creation. Most Nerves users start it automatically as
an OTP application. This is easy, but may be limiting and it requires that you
use the application environment. See the following sections for options:
###
[Starting as an OTP application](#starting-as-an-otp-application)
If you're using [`:nerves_pack`](https://hex.pm/packages/nerves_pack) v0.4.0 or
later, you don't need to do anything except verify the `:nerves_ssh`
configuration in your `config.exs` (see below). If you are not using
`:nerves_pack`, add `:nerves_ssh` to your `mix` dependency list:
```
def deps do
[
{:nerves\_ssh, "~> 0.1.0", targets: @all\_targets}
]
end
```
And then include it in `:shoehorn`'s `:init` list:
```
config :shoehorn,
init: [:nerves\_runtime, :vintage\_net, :nerves\_ssh]
```
`:nerves_ssh` will work if you do not add it to the `:init` list. However, if
your main OTP application stops, OTP may stop `:nerves_ssh`, and that would make
your device inaccessible via SSH.
###
[Starting as part of one of your supervision trees](#starting-as-part-of-one-of-your-supervision-trees)
If you want to do this, make sure that you do NOT specify `:nerves_ssh` in your
`config.exs`. The `:nerves_ssh` key decides whether or not to automatically launch
based on this.
Then when specifying the children for your supervisor, add [`NervesSSH`](NervesSSH.html) like
this:
```
{NervesSSH, nerves\_ssh\_options}
```
The `nerves_ssh_options` should be a [`NervesSSH.Options`](NervesSSH.Options.html) struct. See the
`Configuration` section option fields that you may specify. Calling
`NervesSSH.Options.with_defaults(my_options_list)` to build the
`nerves_ssh_options` value is one way of getting reasonable defaults.
[Configuration](#configuration)
--------------------------------
NervesSSH supports the following configuration items:
* `:authorized_keys` - a list of SSH authorized key file string
* `:user_passwords` - a list of username/password tuples (stored in the
clear!)
* `:port` - the TCP port to use for the SSH daemon. Defaults to `22`.
* `:subsystems` - a list of [SSH subsystems specs](https://erlang.org/doc/man/ssh.html#type-subsystem_spec) to start.
Defaults to SFTP and `ssh_subsystem_fwup`
* `:system_dir` - where to find host keys. Defaults to `"/data/nerves_ssh"`
* `:shell` - the language of the shell (`:elixir`, `:erlang`, `:lfe`, or
`:disabled`). Defaults to `:elixir`.
* `:exec` - the language to use for commands sent over ssh (`:elixir`,
`:erlang`, `lfe`, or `:disabled`). Defaults to `:elixir`.
* `:iex_opts` - additional options to use when starting up IEx
* `:daemon_option_overrides` - additional options to pass to [`:ssh.daemon/2`](https://www.erlang.org/doc/man/ssh.html#daemon-2).
These take precedence and are unchecked. Be careful using this since it can
break other options.
###
[SSH host keys](#ssh-host-keys)
SSH identifies itself to clients using a host key. Clients can record the key
and use it to detect man-in-the-middle attacks and other shenanigans on future
connections. Host keys are stored in the `:system_dir` (see configuration) and
named `ssh_host_rsa_key`, `ssh_host_ed25519_key`, etc.
NervesSSH will create a host key the first time it starts if one does not exist.
The key will be stored in `:system_dir`. Be aware that the host key is not
encrypted or protected so anyone with access to the device can get it if they
choose.
If the `:system_dir` is not writable, NervesSSH will create an in-memory host
key so that users can still log in. In fact, even if the file system is
writable, NervesSSH will verify the host key before using it and recreate it if
corrupt. The goal is that broken host keys to not result in a situation where
it's impossible to log into a device. Your SSH client complaining about the host
key changing will be the hint that something is wrong.
NervesSSH currently supports
[Ed25519](https://en.wikipedia.org/wiki/EdDSA#Ed25519) and
[RSA](https://en.wikipedia.org/wiki/RSA_(cryptosystem)) host keys.
If you rewrite your MicroSD cards often and don't want to get SSH client errors,
add the following to your `~/.ssh/config`:
```
Host nerves.local
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
```
[Authentication](#authentication)
----------------------------------
It's possible to set up a number of authentication strategies with the Erlang
SSH daemon. Currently, only simple public key and username/password
authentication setups are supported by `:nerves_ssh`. Both of them work fine for
getting started. As needs become more sophisticated, you can pass options to
`:daemon_option_overrides`.
###
[Public key authentication](#public-key-authentication)
Public ssh keys can be specified so that matching clients can connect. These
come from files like your `~/.ssh/id_rsa.pub` or `~/.ssh/id_ecdsa.pub` that were
created when you created your `ssh` keys. If you haven't done this, the
following
[article](https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/)
may be helpful. Here's an example that uses the application config:
```
config :nerves\_ssh,
authorized\_keys: [
"ssh-rsa
AAAAB3NzaC1yc2EAAAADAQABAAAAgQDBCdMwNo0xOE86il0DB2Tq4RCv07XvnV7W1uQBlOOE0ZZVjxmTIOiu8XcSLy0mHj11qX5pQH3Th6Jmyqdj",
"ssh-rsa
AAAAB3NzaC1yc2EAAAADAQABAAACAQCaf37TM8GfNKcoDjoewa6021zln4GvmOiXqW6SRpF61uNWZXurPte1u8frrJX1P/hGxCL7YN3cV6eZqRiF"
]
```
Here's another way that may work well for you that avoids needing to commit your
keys:
```
config :nerves\_ssh,
authorized\_keys: [
File.read!(Path.join(System.user\_home!, ".ssh/id\_rsa.pub"))
]
```
See [`NervesSSH.add_authorized_key/1`](NervesSSH.html#add_authorized_key/1) and [`NervesSSH.remove_authorized_key/1`](NervesSSH.html#remove_authorized_key/1)
for managing public keys at runtime.
###
[Username/password authentication](#username-password-authentication)
The SSH console uses public key authentication by default, but it can be
configured for usernames and passwords via the `:user_passwords` key. This has
the form `[{"username", "password"}, ...]`. Keep in mind that passwords are
stored in the clear. This is not recommended for most situations.
```
config :nerves\_ssh,
user\_passwords: [
{"username", "password"}
]
```
You can use [`NervesSSH.add_user/2`](NervesSSH.html#add_user/2) and [`NervesSSH.remove_user/1`](NervesSSH.html#remove_user/1) for managing
credentials at runtime, but they are not saved to disk so restarting [`NervesSSH`](NervesSSH.html)
will cause them to be lost (such as a reboot or daemon crash)
[Upgrade from `NervesFirmwareSSH`](#upgrade-from-nervesfirmwaressh)
--------------------------------------------------------------------
If you are migrating from `:nerves_firmware_ssh`, or updating to `:nerves_pack >= 0.4.0`, you will need to make a few changes to your existing project.
1. Generate a `upload.sh` script by running [`mix firmware.gen.script`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Firmware.Gen.Script.html) (if you
don't already have one)
* This is necessary because you will no longer have access to your old
[`mix upload`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Upload.html) command because `nerves_firmware_ssh` is being removed from
the project.
2. Change all `:nerves_firmware_ssh` config values to `:nerves_ssh`. A command
like this would probably do the trick:
```
grep -RIl nerves\_firmware\_ssh config/ | xargs sed -i 's/nerves\_firmware\_ssh/nerves\_ssh/g'
```
3. Compile your new firmware that includes `:nerves_ssh` (or updated
`:nerves_pack`)
* **NOTE** Compiling your new firmware for the first time will generate a
warning about the old `upload.sh` script still being around. You can
ignore that **this one time** because you will need it for uploading to an
existing device still using port 8989.
4. Upload your new firmware with `:nerves_ssh` using the ***old*** `upload.sh`
script (or whatever other method you have been using for OTA firmware
updates)
5. After the new firmware with `:nerves_ssh` is on the device, then you'll need
to generate the new `upload.sh` script with [`mix firmware.gen.script`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Firmware.Gen.Script.html), or see
[SSHSubsystemFwup](https://hexdocs.pm/ssh_subsystem_fwup/readme.html) for
other supported options
[Goals](#goals)
----------------
* [X] Support public key authentication
* [X] Support username/password authentication
* [X] Device generated server certificate and key
* [ ] Device generated username/password

it's impossible to log into a device. Your SSH client complaining about the host
key changing will be the hint that something is wrong.
NervesSSH currently supports
[Ed25519](https://en.wikipedia.org/wiki/EdDSA#Ed25519) and
[RSA](https://en.wikipedia.org/wiki/RSA_(cryptosystem)) host keys.
If you rewrite your MicroSD cards often and don't want to get SSH client errors,
add the following to your `~/.ssh/config`:
```
Host nerves.local
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
```
[Authentication](#module-authentication)
-----------------------------------------
It's possible to set up a number of authentication strategies with the Erlang
SSH daemon. Currently, only simple public key and username/password
authentication setups are supported by `:nerves_ssh`. Both of them work fine for
getting started. As needs become more sophisticated, you can pass options to
`:daemon_option_overrides`.
###
[Public key authentication](#module-public-key-authentication)
Public ssh keys can be specified so that matching clients can connect. These
come from files like your `~/.ssh/id_rsa.pub` or `~/.ssh/id_ecdsa.pub` that were
created when you created your `ssh` keys. If you haven't done this, the
following
[article](https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/)
may be helpful. Here's an example that uses the application config:
```
config :nerves\_ssh,
authorized\_keys: [
"ssh-rsa
AAAAB3NzaC1yc2EAAAADAQABAAAAgQDBCdMwNo0xOE86il0DB2Tq4RCv07XvnV7W1uQBlOOE0ZZVjxmTIOiu8XcSLy0mHj11qX5pQH3Th6Jmyqdj",
"ssh-rsa
AAAAB3NzaC1yc2EAAAADAQABAAACAQCaf37TM8GfNKcoDjoewa6021zln4GvmOiXqW6SRpF61uNWZXurPte1u8frrJX1P/hGxCL7YN3cV6eZqRiF"
]
```
Here's another way that may work well for you that avoids needing to commit your
keys:
```
config :nerves\_ssh,
authorized\_keys: [
File.read!(Path.join(System.user\_home!, ".ssh/id\_rsa.pub"))
]
```
See [`NervesSSH.add_authorized_key/1`](#add_authorized_key/1) and [`NervesSSH.remove_authorized_key/1`](#remove_authorized_key/1)
for managing public keys at runtime.
###
[Username/password authentication](#module-username-password-authentication)
The SSH console uses public key authentication by default, but it can be
configured for usernames and passwords via the `:user_passwords` key. This has
the form `[{"username", "password"}, ...]`. Keep in mind that passwords are
stored in the clear. This is not recommended for most situations.
```
config :nerves\_ssh,
user\_passwords: [
{"username", "password"}
]
```
You can use [`NervesSSH.add_user/2`](#add_user/2) and [`NervesSSH.remove_user/1`](#remove_user/1) for managing
credentials at runtime, but they are not saved to disk so restarting [`NervesSSH`](NervesSSH.html#content)
will cause them to be lost (such as a reboot or daemon crash)
[Upgrade from `NervesFirmwareSSH`](#module-upgrade-from-nervesfirmwaressh)
---------------------------------------------------------------------------
If you are migrating from `:nerves_firmware_ssh`, or updating to `:nerves_pack >= 0.4.0`, you will need to make a few changes to your existing project.
1. Generate a `upload.sh` script by running [`mix firmware.gen.script`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Firmware.Gen.Script.html) (if you
don't already have one)
* This is necessary because you will no longer have access to your old
[`mix upload`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Upload.html) command because `nerves_firmware_ssh` is being removed from
the project.
2. Change all `:nerves_firmware_ssh` config values to `:nerves_ssh`. A command
like this would probably do the trick:
```
grep -RIl nerves\_firmware\_ssh config/ | xargs sed -i 's/nerves\_firmware\_ssh/nerves\_ssh/g'
```
3. Compile your new firmware that includes `:nerves_ssh` (or updated
`:nerves_pack`)
* **NOTE** Compiling your new firmware for the first time will generate a
warning about the old `upload.sh` script still being around. You can
ignore that **this one time** because you will need it for uploading to an
existing device still using port 8989.
4. Upload your new firmware with `:nerves_ssh` using the ***old*** `upload.sh`
script (or whatever other method you have been using for OTA firmware
updates)
5. After the new firmware with `:nerves_ssh` is on the device, then you'll need
to generate the new `upload.sh` script with [`mix firmware.gen.script`](https://hexdocs.pm/ssh_subsystem_fwup/0.6.1/Mix.Tasks.Firmware.Gen.Script.html), or see
[SSHSubsystemFwup](https://hexdocs.pm/ssh_subsystem_fwup/readme.html) for
other supported options

NervesSSH.Options
(nerves\_ssh v0.4.3)
======================================================================================================================================================================
Defines option for running the SSH daemon.
The following fields are available:
* `:name` - a name used to reference the NervesSSH-managed SSH daemon. Defaults to [`NervesSSH`](NervesSSH.html).
* `:authorized_keys` - a list of SSH authorized key file string
* `:port` - the TCP port to use for the SSH daemon. Defaults to `22`.
* `:subsystems` - a list of [SSH subsystems specs](https://erlang.org/doc/man/ssh.html#type-subsystem_spec) to start. Defaults to SFTP and `ssh_subsystem_fwup`
* `:user_dir` - where to find authorized\_keys file
* `:system_dir` - where to find host keys
* `:shell` - the language of the shell (`:elixir`, `:erlang`, `:lfe` or `:disabled`). Defaults to `:elixir`.

Tracer
(Exrun v0.2.1)
================================================================================================================================
Main interface for tracing functionallity.
Usage:
```
use Tracer
trace Map.new()
```
Options:
* `:node` - specified the node, on which trace should be started.
* `:limit` - specifies the limit, that should be used on collectable process.
Limit options are merged with actually setted. It is possible to specify it
per configuration as env `:limit` for application `:exrun`.
The following limit options are available:
+ `:time` - specifies the time in milliseconds, where should the rate be
applied. Default specified by environments. (Default: 1000)
+ `:rate` - specifies the limit of trace messages per time, if trace messages
will be over this limit, the collectable process will stop and clear all traces.
Default specified by environments. (Default: 250)
+ `:overall` - set the absolute limit for messages. After reaching this limit, the
collactable process will clear all traces and stops. Default specified by environments.
(Default: nil)Additionally limit can be specified as `limit: 5`, than it equivalent to `limit: %{overall: 5}`
* `:formatter_local` - flag for setting, where formatter process should be started.
If set to `false`, then the formatter process will be started on remote node, if set
to `true`, on a local machine. Defaults set to `false`. Tracer can trace on nodes,
where elixir is not installed. If formatter\_local set to true, there will be only 2
modules loaded on remote erlang node (Tracer.Utils and Tracer.Collector), which forward
messages to the connected node. If formatter\_local set to false, than formatter started
on remote node and it load all modules from elixir application, because for formatting
traces there should be loaded at least all Inspect modules.
* `:formatter` - own formatter function, example because you try to trace different
inspect function. Formatter is either a fun or tuple `{module, function, opts}`.
* `:format_opts` - any format options, which will be passed to [`inspect/2`](https://hexdocs.pm/elixir/Kernel.html#inspect/2). Per default structs
are disabled.
* `:io` - specify io process, which should handle io from a tracer or a tuple `{init_fun, handle_fun}`, which
handles initialization and io process. `init_fun` has zero arguments and should return `io`, which will be
passed to `handle_fun` together with a message.
* `:unlink` - tracer won't be stoped once a process started it terminates. (should be used for tracing into files
or using network)
* `:file` - specifies a file, where traces should be saved. Option `[file: "/tmp/trace.log"]` is a shortcut for
`[unlink: true, io: {{File, :open!, ["/tmp/trace.log", [:append]]}, {IO, :puts, []}}]`

[](https://github.com/MikaAK/request_cache_plug/actions/workflows/test-actions.yml)
[](https://codecov.io/gh/MikaAK/request_cache_plug)
[](https://hex.pm/packages/request_cache_plug)
This plug allows us to cache our graphql queries and phoenix controller requests declaritevly
We call the cache inside either a resolver or a controller action and this will store it preventing further
executions of our query on repeat requests.
The goal of this plug is to short-circuit any processing phoenix would
normally do upon request including json decoding/parsing, the only step that should run is telemetry
###
[installation](#module-installation)
Installation
This package can be installed by adding `request_cache_plug` to your list of dependencies in `mix.exs`:
```
def deps do
[
{:request\_cache\_plug, "~> 0.2"}
]
end
```
Documentation can be found at <https://hexdocs.pm/request_cache_plug>.
###
[config](#module-config)
Config
This is the default config, it can all be changed
```
config :request\_cache\_plug,
enabled?: true,
verbose?: false,
graphql\_paths: ["/graphiql", "/graphql"],
conn\_priv\_key: :\_\_shared\_request\_cache\_\_,
request\_cache\_module: RequestCache.ConCacheStore,
default\_ttl: :timer.hours(1),
default\_concache\_opts: [
ttl\_check\_interval: :timer.seconds(1),
acquire\_lock\_timeout: :timer.seconds(1),
ets\_options: [write\_concurrency: true, read\_concurrency: true]
]
```
###
[usage](#module-usage)
Usage
This plug is intended to be inserted into the `endpoint.ex` fairly early in the pipeline,
it should go after telemetry but before our parsers
```
plug Plug.Telemetry, event\_prefix: [:phoenix, :endpoint]
plug RequestCache.Plug
plug Plug.Parsers,
parsers: [:urlencoded, :multipart, :json],
pass: ["\*/\*"]
```
We also need to setup a before\_send hook to our absinthe\_plug (if not using absinthe you can skip this step)
```
plug Absinthe.Plug, before\_send: {RequestCache, :connect\_absinthe\_context\_to\_conn}
```
What this does is allow us to see the results of items we put onto our request context from within plugs coming after absinthe
After that we can utilize our cache in a few ways
#### Utilization with Phoenix Controllers
```
def index(conn, params) do

###
[specifying-specific-caching-locations](#module-specifying-specific-caching-locations)
Specifying Specific Caching Locations
We have a few ways to control the caching location of our RequestCache, by default if you have `con_cache` installed,
we have access to `RequestCache.ConCacheStore` which is the default setting
However we can override this by setting `config :request_cache_plug, :request_cache_module, MyCustomCache`
Caching module will be expected to have the following API:
```
def get(key) do
...
end
def put(key, ttl, value) do
...
end
```
You are responsible for starting the cache, including ConCacheStore, so if you're planning to use it make sure
you add `RequestCache.ConCacheStore` to the application.ex list of children
***Specifying the module per function is currently not fully implemented, check back soon for updates***
We can also override the module for a particular request by passing the option to our graphql middleware or
our `&RequestCache.store/2` function as `[ttl: 123, cache: MyCacheModule]`
##### With Middleware
```
field :user, :user do
arg :id, non\_null(:id)
middleware RequestCache.Middleware, ttl: :timer.seconds(60), cache: MyCacheModule
resolve &Resolvers.User.find/2
end
```
##### In a Resolver
```
def all(params, resolution) do
RequestCache.store(value, ttl: :timer.seconds(60), cache: MyCacheModule)
end
```
##### In a Controller
```
def index(conn, params) do
RequestCache.store(conn, ttl: :timer.seconds(60), cache: MyCacheModule)
end
```
###
[telemetry](#module-telemetry)
telemetry
Cache events are emitted via :telemetry. Events are:
* `[:request_cache_plug, :graphql, :cache_hit]`
* `[:request_cache_plug, :graphql, :cache_miss]`
* `[:request_cache_plug, :rest, :cache_hit]`
* `[:request_cache_plug, :rest, :cache_miss]`
* `[:request_cache_plug, :cache_put]`
For GraphQL endpoints it is possible to provide a list of atoms that will be passed through to the event metadata; e.g.:
##### With Middleware
```
field :user, :user do
arg :id, non\_null(:id)
middleware RequestCache.Middleware,
ttl: :timer.seconds(60),
cache: MyCacheModule,
labels: [:service, :endpoint],
whitelisted\_query\_names: ["MyQueryName"] # By default all queries are cached, can also whitelist based off query name from GQL Document
resolve &Resolvers.User.find/2
end
```
##### In a Resolver
```
def all(params, resolution) do
RequestCache.store(value, ttl: :timer.seconds(60), cache: MyCacheModule, labels: [:service, :endpoint])
end
```
The events will look like this:
```
{
[:request\_cache\_plug, :graphql, :cache\_hit],
%{count: 1},
%{ttl: 3600000, cache\_key: "/graphql:NNNN", labels: [:service, :endpoint]}
}
```
##### Enable Error Caching
In order to enable error caching we can either setup `cached_errors` in our config
or as an option to `RequestCache.store` or [`RequestCache.Middleware`](RequestCache.Middleware.html).
The value of `cached_errors` can be one of `[]`, `:all` or a list of reason\_atoms as
defined by [`Plug.Conn.Status`](https://hexdocs.pm/plug/1.13.4/Plug.Conn.Status.html) such as `:not_found`, or `:internal_server_error`.
In REST this works off the response codes returned. However, in order to use reason\_atoms in GraphQL
you will need to make sure your errors contain some sort of `%{code: "not_found"}` response in them
Take a look at [error\_message](https://github.com/MikaAK/elixir_error_message) for a compatible error system
###
[notes-gotchas](#module-notes-gotchas)
Notes/Gotchas
* In order for this caching to work, we cannot be using POST requests as specced out by GraphQL, not for queries at least, fortunately this doesn't actually matter since we can use any http method we want (there will be a limit to query size), in a production app you may be doing this already due to the caching you gain from CloudFlare
* Caches are stored via a MD5 hashed key that correlates to your query in GraphQL, or in REST your url path + query parameters
* Absinthe and ConCache are optional dependencies, if you don't have them you won't have access to [`RequestCache.Middleware`](RequestCache.Middleware.html) or `RequestCache.ConCacheStore`
* If no ConCache is found, you must set `config :request_cache_module` to something else
###
[caching-header](#module-caching-header)
Caching Header
When an item is served from the cache, we return a header `rc-cache-status` which has a value of `HIT`. Using this you can tell if the item was
served out of cache, without it the item was fetched

Example Reduction
In the case of a large (16mb) payload running through absinthe, this plug cuts down response times from 400+ms -> <400ΞΌs

[](https://travis-ci.org/danhper/elixir-browser)
Browser detection for Elixir.
This is a port from the [Ruby browser library](https://github.com/fnando/browser).
All the detection features have been ported, but not the meta and the language ones.
Installation
---------------
Add `browser` to your list of dependencies in `mix.exs`:
```
def deps do
[{:browser, "~> 0.4.4"}]
end
```
Usage
--------
```
ua = "some string"
Browser.name(ua) # readable browser name
Browser.version(ua) # major version number
Browser.full\_version(ua)
Browser.full\_browser\_name(ua) # Chrome 5.0.375.99
Browser.full\_display(ua) # example: Chrome 5.0.375.99 on MacOS 10.6.4 Snow Leopard

Browser.ie?(ua)
Browser.ie?(ua, 6) # detect specific IE version
Browser.edge?(ua) # Newest MS browser
Browser.modern?(ua) # Webkit, Firefox 17+, IE 9+ and Opera 12+
Browser.platform(ua) # return :ios, :android, :mac, :windows, :linux or :other
Browser.full\_platform\_name(ua) # example: MacOS 10.6.4 Snow Leopard
Browser.device\_type(ua) # return :mobile, :tablet, :desktop, :console, :unknown
Browser.ios?(ua) # detect iOS
Browser.ios?(ua, 9) # detect specific iOS version
Browser.mac?(ua)
Browser.mac\_version(ua) # display version of Mac OSX. i.e. High Sierra
Browser.windows?(ua)
Browser.windows\_x64?(ua)
Browser.windows\_version\_name # display version of Windows. i.e. Windows 10
Browser.linux?(ua)
Browser.blackberry?(ua)
Browser.blackberry?(ua, 10) # detect specific BlackBerry version
Browser.bot?(ua)
Browser.search\_engine?(ua)
Browser.phantom\_js?(ua)
Browser.quicktime?(ua)
Browser.core\_media?(ua)
Browser.silk?(ua)
Browser.android?(ua)
Browser.android?(ua, 4.2) # detect Android Jelly Bean 4.2
Browser.known?(ua) # has the browser been successfully detected?
```
See the [original Ruby library](https://github.com/fnando/browser) for more information.
###
Elixir addition
You can also pass [`Plug.Conn`](https://hexdocs.pm/plug/1.13.3/Plug.Conn.html) instead of a string, the `user-agent` header will
be extracted and used.
```
Browser.bot?(conn)
```
###
Configuration
You can specify custom bots.txt file in your project's config.
```
config :browser,
bots\_file: Path.join(File.cwd!, "bots.txt") # bots.txt in project's root
```
Please note that option set as mobule attribute during compile time, so make sure you recompiled elixir-browser after changing this option or bots file itself.

===========================================
FakerElixir is an Elixir package that **generates fake data** for you. Whether you need to **seed** your database, create **factories** for your project, FakerElixir is here for you.
Installation
---------------
Canβt wait to generate some fake data ? Follow the steps:
1. Add `faker_elixir_octopus` to your list of dependencies in `mix.exs`:
```
def deps do
[{:faker_elixir_octopus, "> 0.0.0"}]
end
```
1. Ensure `faker_elixir` is started before your application:
```
def application do
[applications: [:faker_elixir_octopus]]
end
```
1. Run in the root of your project:
```
$ mix deps.get
```
1. Faker Elixir is now a part of your application and ready to use!
Usage
--------
Since Iβm quite sure you are using Phoenix, I will show you a basic example:
```
defmodule Zombie.AwesomeController do
use Zombie.Web, :controller
def index(conn, _params) do
text conn, FakerElixir.Helper.pick(["zombie", "human"])
end
end
```
Now if you keep refreshing your browser, the value should change. Awesome, you just understood how to use Faker.
Summary

[Functions](#functions)
------------------------
[get\_locale()](#get_locale/0)
Return the current locale set
[set\_locale(locale)](#set_locale/1)
The default locale used by FakerElixir is `:en`
Functions
============
get\_locale()
Return the current locale set
```
iex> FakerElixir.get_locale
:en
```
set\_locale(locale)
The default locale used by FakerElixir is `:en`.
Right now only 4 locales are available: `:fr`, `:en`, `:es`, `:it`.
If you set a different locale, FakerElixir will just fallback to `:en` (If you didnβt provide a custom locale)
Note: Keep in mind you can set the locale at the runtime, the locale set will keep his state until you set another locale
Examples
--------
```
iex> FakerElixir.set_locale(:en)
:ok
iex> FakerElixir.Address.city
"Baltimore"
iex> FakerElixir.set_locale(:fr)
:ok
iex> FakerElixir.Address.city
"Issy-les-Moulineaux"

Geocalc.Point protocol
--------------------------------------------------------------------------
Everything which implements [`Geocalc.Point`](Geocalc.Point.html) protocol can be passed as a point
argument for any function in this library.
We already have implementations for [`List`](https://hexdocs.pm/elixir/List.html), [`Tuple`](https://hexdocs.pm/elixir/Tuple.html) and [`Map`](https://hexdocs.pm/elixir/Map.html).
You can define your own implementations if you need, everything we need to know
to do calculations are `latitude` and `longitude`.
[geocalc-dms](#geocalc-dms)
Geocalc.DMS

BiMap
(BiMap v1.2.2)
=================================================================================================================================
Bi-directional map implementation backed by two maps.
> In computer science, a bidirectional map, or hash bag, is an associative data
> structure in which the `(key, value)` pairs form a one-to-one correspondence.
> Thus the binary relation is functional in each direction: `value` can also
> act as a key to `key`. A pair `(a, b)` thus provides a unique coupling
> between a `a` and `b` so that `b` can be found when `a` is used as a key and
> `a` can be found when `b` is used as a key.

Entries in bimap do not follow any order.
BiMaps do not impose any restriction on the key and value type: anything can be
a key in a bimap, and also anything can be a value. As a bidirectional
key-value structure, bimaps do not allow duplicated keys and values. This means
it is not possible to store `[(A, B), (A, C)]` or `[(X, Z), (Y, Z)]` in
the bimap. If you need to lift this restriction to only not allowing duplicated
key-value pairs, check out [`BiMultiMap`](BiMultiMap.html).
Keys and values are compared using the exact-equality operator (`===`).

Example
------------------------------------
```
iex> bm = BiMap.new(a: 1, b: 2)
#BiMap<[a: 1, b: 2]>
iex> BiMap.get(bm, :a)
1
iex> BiMap.get\_key(bm, 2)
:b
iex> BiMap.put(bm, :a, 3)
#BiMap<[a: 3, b: 2]>
iex> BiMap.put(bm, :c, 2)
#BiMap<[a: 1, c: 2]>

```
@spec put_new_value([t](#t:t/0)(), [k](#t:k/0)(), [v](#t:v/0)()) :: [t](#t:t/0)()
```
Inserts `{key, value}` pair into `bimap` if `value` is not already in `bimap`.
If `value` already exists in `bimap`, `bimap` is returned unchanged.
If `value` does not exist and `key` is already in `bimap`, any overlapping bindings are
deleted.

BiMultiMap
(BiMap v1.2.2)
===========================================================================================================================================
Bi-directional multimap implementation backed by two multimaps.
Entries in bimap do not follow any order.
BiMultiMaps do not impose any restriction on the key and value type: anything
can be a key in a bimap, and also anything can be a value.
BiMultiMaps differ from [`BiMap`](BiMap.html)s by disallowing duplicates only among key-value
pairs, not among keys and values separately. This means it is possible to store
`[(A, B), (A, C)]` or `[(X, Z), (Y, Z)]` in BiMultiMap.
Keys and values are compared using the exact-equality operator (`===`).
[example](#module-example)
Example
------------------------------------
```
iex> mm = BiMultiMap.new(a: 1, b: 2, b: 1)
#BiMultiMap<[a: 1, b: 1, b: 2]>
iex> BiMultiMap.get(mm, :a)
[1]
iex> BiMultiMap.get\_keys(mm, 1)
[:a, :b]
iex> BiMultiMap.put(mm, :a, 3)
#BiMultiMap<[a: 1, a: 3, b: 1, b: 2]>
```
[protocols](#module-protocols)
Protocols
------------------------------------------
[`BiMultiMap`](BiMultiMap.html#content) implements [`Enumerable`](https://hexdocs.pm/elixir/Enumerable.html), [`Collectable`](https://hexdocs.pm/elixir/Collectable.html) and [`Inspect`](https://hexdocs.pm/elixir/Inspect.html) protocols.

Introduction
---------------
Traditional MVC Frameworks (Rails, Django, .Net, Phoenix, etc) leave it up to the user to build the glue between requests for data (HTTP requests in various forms as well as server-side domain logic) and their respective ORMs. In that space, there is an incredible amount of boilerplate code that must get written from scratch for each application (authentication, authorization, sorting, filtering, sideloading relationships, serialization, etc).
Ash is an opinionated yet configurable framework designed to reduce boilerplate in an Elixir application. Ash does this by providing a layer of abstraction over your system's data layer(s) withΒ `Resources`. It is designed to be used in conjunction with a phoenix application, or on its own.
To riff on a famous JRR Tolkien quote, aΒ `Resource`is "One Interface to rule them all, One Interface to find them" and will become an indispensable place to define contracts for interacting with data throughout your application.
To start using Ash, first declare your `Resources` using the Ash `Resource` DSL. You could technically stop there, and just leverage the Ash Elixir API to avoid writing boilerplate. More likely, you would use extensions like Ash.JsonApi or Ash.GraphQL with Phoenix to add external interfaces to those resources without having to write any extra code at all.
Ash is an open-source project and draws inspiration from similar ideas in other frameworks and concepts. The goal of Ash is to lower the barrier to adopting and using Elixir and Phoenix, and in doing so help these amazing communities attract new developers, projects, and companies.
Example Resource
-------------------
```
defmodule Post do
use Ash.Resource
actions do
read :default
create :default
end
attributes do
attribute :name, :string
end
relationships do
belongs\_to :author, Author
end
end
```
See the [getting started guide](getting_started.html) for more information.
For those looking to add ash extensions:
* see [`Ash.Dsl.Extension`](Ash.Dsl.Extension.html) for adding configuration.
* If you are looking to write a new data source, also see the [`Ash.DataLayer`](Ash.DataLayer.html) documentation.
* If you are looking to write a new authorizer, see [`Ash.Authorizer`](Ash.Authorizer.html)
* If you are looking to write a "front end", something powered by Ash resources, a guide on
building those kinds of tools is in the works.

Ash.Api behaviour [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/api/api.ex#L1 "View Source")
=================================================================================================================================
An Api allows you to interact with your resources, and holds non-resource-specific configuration.
Your Api can also house config that is not resource specific.
Defining a resource won't do much for you. Once you have some resources defined,
you include them in an Api like so:
```
defmodule MyApp.Api do
use Ash.Api
resources do
resource OneResource
resource SecondResource
end
```
Then you can interact through that Api with the actions that those resources expose.
For example: `MyApp.Api.create(changeset)`, or `MyApp.Api.read(query)`. Corresponding
actions must be defined in your resources in order to call them through the Api.

ash v0.11.0
Ash.Changeset [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/changeset/changeset.ex#L1 "View Source")
=========================================================================================================================================
Changesets are used to create and update data in Ash.
Create a changeset with `create/2` or `update/2`, and alter the attributes
and relationships using the functions provided in this module. Nothing in this module
actually incurs changes in a data layer. To commit a changeset, see [`Ash.Api.create/2`](Ash.Api.html#c:create/2)
and [`Ash.Api.update/2`](Ash.Api.html#c:update/2).
Primary Keys
---------------
For relationship manipulation using [`append_to_relationship/3`](#append_to_relationship/3), [`remove_from_relationship/3`](#remove_from_relationship/3)
and [`replace_relationship/3`](#replace_relationship/3) there are three types that can be used for primary keys:
1.) An instance of the resource in question.
2.) If the primary key is just a single field, i.e `:id`, then a single value, i.e `1`
3.) A map of keys to values representing the primary key, i.e `%{id: 1}` or `%{id: 1, org_id: 2}`
Join Attributes
------------------
For many to many relationships, the attributes on a join relationship may be set while relating items
by passing a tuple of the primary key and the changes to be applied. This is done via upserts, so
update validations on the join resource are *not* applied, but create validations are.
For example:
```
Ash.Changeset.replace\_relationship(changeset, :linked\_tickets, [
{1, %{link\_type: "blocking"}},
{a\_ticket, %{link\_type: "caused\_by"}},
{%{id: 2}, %{link\_type: "related\_to"}}
])
```

=====================================================================================================================================================
The interface for being an ash data layer.
This is a large behaviour, and this capability is not complete, but the idea
is to have a large amount of optional callbacks, and use the [`can?/2`](#can?/2) callback
to ensure that the engine only ever tries to interact with the data layer in ways
that it supports.

An Mnesia backed Ash Datalayer.
In your application intialization, you will need to call `Mnesia.create_schema([node()])`.
Additionally, you will want to create your mnesia tables there.
This data layer is *extremely unoptimized*, fetching all records from a table and filtering them
in place. This is primarily used for testing the behavior of data layers in Ash. If it was improved,
it could be a viable data layer.

(macro)
A section for declaring resource actions.
All manipulation of data through the underlying data layer happens through actions.
There are four types of action: `create`, `read`, `update`, and `destroy`. You may
recognize these from the acronym `CRUD`. You can have multiple actions of the same
type, as long as they have different names. This is the primary mechanism for customizing
your resources to conform to your business logic. It is normal and expected to have
multiple actions of each type in a large application.
If you have multiple actions of the same type, one of them must be designated as the
primary action for that type, via: `primary?: true`. This tells the ash what to do
if an action of that type is requested, but no specific action name is given.

Ash.Dsl.Entity [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/dsl/entity.ex#L1 "View Source")
=================================================================================================================================
Declares a DSL entity.
A dsl entity represents a dsl constructor who's resulting value is a struct.
This lets the user create complex objects with arbitrary(mostly) validation rules.
The lifecycle of creating entities is complex, happening as Elixir is compiling
the modules in question. Some of the patterns around validating/transforming entities
have not yet solidified. If you aren't careful and don't follow the guidelines listed
here, you can have subtle and strange bugs during compilation. Anything not isolated to
simple value validations should be done in `transformers`. See [`Ash.Dsl.Transformer`](Ash.Dsl.Transformer.html).
An entity has a `target` indicating which struct will ultimately be built. An entity
also has a `schema`. This schema is used for documentation, and the options are validated
against it before continuing on with the DSL.
To create positional arguments to the builder, use `args`. The values provided to
`args` need to be in the provided schema as well. They will be positional arguments
in the same order that they are provided in the `args` key.
`auto_set_fields` will set the provided values into the produced struct (they do not need
to be included in the schema).
`transform` is a function that takes a created struct and can alter it. This happens immediately
after handling the DSL options, and can be useful for setting field values on a struct based on
other values in that struct. If you need things that aren't contained in that struct, use an
[`Ash.Dsl.Transformer`](Ash.Dsl.Transformer.html).
`entities` allows you to specify a keyword list of nested entities. Nested entities are stored
on the struct in the corresponding key, and are used in the same way entities are otherwise.
For a full example, see [`Ash.Dsl.Extension`](Ash.Dsl.Extension.html).

Ash.Dsl.Extension behaviour [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/dsl/extension.ex#L1 "View Source")
=================================================================================================================================================
An extension to the Ash DSL.
This allows configuring custom DSL components, whos configurations
can then be read back.
The example at the bottom shows how you might build a (not very contextually
relevant) DSL extension that would be used like so:
```
defmodule MyApp.MyResource do
use Ash.Resource,
extensions: [MyApp.CarExtension]
cars do
car :mazda, "6", trim: :touring
car :toyota, "corolla"
end
end
```
For (a not very contextually relevant) example:
```
defmodule MyApp.CarExtension do
@car\_schema [
make: [
type: :atom,
required: true,
doc: "The make of the car"
],
model: [
type: :atom,
required: true,
doc: "The model of the car"
],
type: [
type: :atom,
required: true,
doc: "The type of the car",
default: :sedan
]
]
@car %Ash.Dsl.Entity{
name: :car,
describe: "Adds a car",
examples: [
"car :mazda, "6""
],
target: MyApp.Car,
args: [:make, :model],
schema: @car\_schema
}
@cars %Ash.Dsl.Section{
name: :cars, # The DSL constructor will be `cars`
describe: """
Configure what cars are available.
More, deeper explanation. Always have a short one liner explanation,
an empty line, and then a longer explanation.
""",
entities: [
@car # See `Ash.Dsl.Entity` docs
],
schema: [
default\_manufacturer: [
type: :atom,
doc: "The default manufacturer"
]
]
}
use Ash.Dsl.Extension, sections: [@cars]
end
```
Often, we will need to do complex validation/validate based on the configuration
of other resources. Due to the nature of building compile time DSLs, there are
many restrictions around that process. To support these complex use cases, extensions
can include `transformers` which can validate/transform the DSL state after all basic
sections/entities have been created. See [`Ash.Dsl.Transformer`](Ash.Dsl.Transformer.html) for more information.
Transformers are provided as an option to `use`, like so:
```
use Ash.Dsl.Extension, sections: [@cars], transformers: [
MyApp.Transformers.ValidateNoOverlappingMakesAndModels
]
```
To expose the configuration of your DSL, define functions that use the
helpers like [`get_entities/2`](#get_entities/2) and `get_opt/3`. For example:
```
defmodule MyApp.Cars do
def cars(resource) do
Ash.Dsl.Extension.get\_entities(resource, [:cars])
end
end
MyApp.Cars.cars(MyResource)
# [%MyApp.Car{...}, %MyApp.Car{...}]
```

(macro)
Declares a `read` action. For calling this action, see the [`Ash.Api`](Ash.Api.html) documentation.
Examples
-----------
```
read :read\_all, primary?: true
```
Arguments
------------
* `:name` - The name of the action
Options
----------
* `:primary?` - Whether or not this action should be used when no action is specified by the caller. The default value is `false`.

Ash.Dsl.Section [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/dsl/section.ex#L1 "View Source")
===================================================================================================================================
Declares a DSL section.
A dsl section allows you to organize related configurations. All extensions
configure sections, they cannot add DSL builders to the top level. This
keeps things organized, and concerns separated.
A section may have nested sections, which will be configured the same as other sections.
Getting the options/entities of a section is done by providing a path, so you would
use the nested path to retrieve that configuration. See [`Ash.Dsl.Extension.get_entities/2`](Ash.Dsl.Extension.html#get_entities/2)
and [`Ash.Dsl.Extension.get_opt/4`](Ash.Dsl.Extension.html#get_opt/4).
A section may have entities, which are constructors that produce instances of structs.
For more on entities, see [`Ash.Dsl.Entity`](Ash.Dsl.Entity.html).
A section may also have a `schema`, which is a [`NimbleOptions`](https://hexdocs.pm/nimble_options/NimbleOptions.html) schema. Ash will produce
builders for those options, so that they may be configured. They are retrived with
[`Ash.Dsl.Extension.get_opt/4`](Ash.Dsl.Extension.html#get_opt/4).
For a full example, see [`Ash.Dsl.Extension`](Ash.Dsl.Extension.html).

Ash.Dsl.Transformer behaviour [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/dsl/transformer.ex#L1 "View Source")
=====================================================================================================================================================
A transformer manipulates and/or validates the entire DSL state of a resource.
It's `transform/2` takes a `map`, which is just the values/configurations at each point
of the DSL. Don't manipulate it directly, if possible, instead use functions like
`get_entities/3` and `replace_entity/5` to manipulate it.
Use the `after?/1` and `before?/1` callbacks to ensure that your transformer
runs either before or after some other transformer.
The pattern for requesting information from other modules that use the DSL and are
also currently compiling has not yet been determined. If you have that requirement
you will need extra utilities to ensure that some other DSL based module has either
completed or reached a certain point in its transformers. These utilities have not
yet been written.

Ash.Resource.Validation behaviour [View Source](https://github.com/ash-project/ash/blob/v0.11.0/lib/ash/resource/validation.ex#L1 "View Source")
=============================================================================================================================================================
Represents a validation in Ash.
See `Ash.Resource.Validation.Builtin` for a list of builtin validations.
To write your own validation, define a module that implements the [`init/1`](#c:init/1) callback
to validate options at compile time, and [`validate/2`](#c:validate/2) callback to do the validation.
Then, in a resource, you can say:
```
validations do
validation {MyValidation, [foo: :bar]}
end
```
To make it more readable, you can define a function in the module that returns that tuple,
and import it into your resource.
```
defmodule MyValidation do
def my\_validation(value) do
{\_\_MODULE\_\_, foo: value}
end
end
```
```
defmodule MyResource do
...
import MyValidation
validations do
validate my\_validation(:foo)
end
end
```

This behaviour is a superset of the Ecto.Type behavior, that also contains
api level information, like what kinds of filters are allowed. Eventually,
this may be used for composite types or serialization.
Much better to `use Ash.Type` than to say `@behaviour Ash.Type` and define
everything yourself.
Built in types
-----------------
* `:term` - [`Ash.Type.Term`](Ash.Type.Term.html)
* `:string` - [`Ash.Type.String`](Ash.Type.String.html)
* `:integer` - [`Ash.Type.Integer`](Ash.Type.Integer.html)
* `:boolean` - [`Ash.Type.Boolean`](Ash.Type.Boolean.html)
* `:uuid` - [`Ash.Type.UUID`](Ash.Type.UUID.html)
* `:date` - [`Ash.Type.Date`](Ash.Type.Date.html)
* `:utc_datetime` - [`Ash.Type.UtcDatetime`](Ash.Type.UtcDatetime.html)
###
Composite Types
Currently, the only composite type supported is a list type, specified via:
`{:array, Type}`. The constraints available are:
* `:items` - Constraints for the elements of the list. See the contained type's docs for more.
* `:min_length` - A minimum length for the items
* `:max_length` - A maximum length for the items
* `:nil_items?` - Whether or not the list can contain nil items The default value is `true`.

ExqUI
[View Source](https://github.com/akira/exq_ui/blob/v0.14.0/README.md#L1 "View Source")
===============================================================================================
[](https://hex.pm/packages/exq_ui)
ExqUI provides a UI dashboard for [Exq](https://github.com/akira/exq), a job processing library
compatible with Resque / Sidekiq for the Elixir language. ExqUI allow
you to see various job processing stats, as well as details on failed,
retried, scheduled jobs, etc.
Configuration
----------------
1. ExqUI depends on the [api server](https://hexdocs.pm/exq/Exq.Api.html#content) component of the [exq](https://github.com/akira/exq). The
user of ExqUI is expected to start the Exq with proper config. The
only config required on ExqUI side is the name of the api
server. It's set to Exq.Api by default.
```
config :exq\_ui,
api\_name: Exq.Api
```
There are two typical scenarios
If ExqUI is embedded in a worker node which runs exq jobs, then
nothing special needs to be done. Exq by default starts the api
server on all worker nodes.
If ExqUI needs to be embedded in a node which is not a worker, then
Exq can be started in `api` mode, which will only start the api
gen server and will not pickup jobs for execution. This can be done
by configuring the `mode`.
```
config :exq,
mode: :api
```
2. ExqUI uses Phoenix LiveView. If you already use LiveView, skip to
next step. Otherwise follow LiveView [installation docs](https://hexdocs.pm/phoenix_live_view/installation.html).
3. In your phoenix router import [`ExqUIWeb.Router`](ExqUIWeb.Router.html) and add
`live_exq_ui(path)`
```
defmodule DemoWeb.Router do
use Phoenix.Router
import ExqUIWeb.Router
pipeline :browser do
plug :fetch\_session
plug :protect\_from\_forgery
end
scope "/", DemoWeb do
pipe\_through :browser
live\_exq\_ui("/exq")
end
end
```
Exq Scheduler
----------------
ExqUI provides support for [Exq Scheduler](https://github.com/activesphere/exq-scheduler). It can be enabled by
giving a name to exq scheduler and specifying the same name in exq ui config.
```
config :exq\_scheduler,
name: ExqScheduler
config :exq\_ui,
exq\_scheduler\_name: ExqScheduler
```
Development
--------------
```
mix setup # on first run
mix run --no-halt dev.exs
open http://localhost:4000/exq
```

Deferred Config
------------------
Seamless runtime config with one line of code. In
your applicationβs `start/2` method, call:
```
DeferredConfig.populate(:otp_app_name)
```
And now you and users of your application or library
will be able to write config that is deferred to
runtime, like the following:
```
config :otp_app_name,
http: %{ # nested config is ok
# common 'system tuple' pattern is fully supported
port: {:system, "PORT", {String, :to_integer}}
},
# more general 'mfa tuple' pattern is also supported
secret_key: {:apply, {MyKey, :fetch, ["arg"]}}
```
Thatβs it.
* No βmappings,β no special access methods β just
keep using [`Application.get_env/2`](https://hexdocs.pm/elixir/Application.html#get_env/2).
* Works for arbitrarily nested config.
* Works just as well when run with mix as it does
in releases built with `:distillery`, `:exrm`,
or `:relx`.
* Lets library authors support the
common βsystem tuplesβ pattern *effortlessly.*
**Why this library?**
See β[Rationale](#rationale)β for more detail. But
**TLDR:** `REPLACE_OS_VARS` is string-only and
release-only, and `{:system, ...}` support among
libraries is inconsistent and easy to get wrong in
ways that bite your users come release time β in
other words, until now itβs been a burden on
library authors. This library tries to make it
1 LOC to do the right thing.
There are other libraries to manage runtime config
(see list at end of readme) but using them is harder
as they add things β like special config accessor functions,
and/or their own config files, or mappings, or DSLs. We donβt
need to, because we rely on a [`ReplacingWalk`](ReplacingWalk.html)
of an appβs config during [`Application.start/2`](https://hexdocs.pm/elixir/Application.html#start/2), and
the only DSL are configuration patterns sourced from
the community, like system and mfa tuples.
Usage
--------
In mix.exs,
```
defp deps, do: [{:deferred_config, "~> 0.1.0"}]
```
Then, in your application startup, add the following line:
```
defmodule Mine.Application do
# ...
def start(_type, _args) do
DeferredConfig.populate(:mine) # <--- here
# ...
end
end
```
Where the app name is `:mine`.
Now, you and users of your app can configure
as follows, and itβll work β regardless of if theyβre
running it from iex, or a release with env vars set:
```
config :mine,
# string from env var, or `nil` if missing.
port1: {:system, "PORT"},
# string from env var |> integer; `nil` if missing.
port2: {:system, "PORT", {String, :to_integer}},
# string from env var, or "4000" as default.
port3: {:system, "PORT", "4000"},
# converts env var to integer, or 4000 as default.
port4: {:system, "PORT", 4000, {String, :to_integer}}
```
Features
-----------
**Accessing config does not change.** If you used
`Application.get_env(:mine, :port1)` before, that will
keep working.
Since you can use arbitrary transformation functions,
**you can do advanced transformations** if you need to:
```
# lib/mine/ip.ex
defmodule Mine.Ip do
@doc ":inet uses `{0,0,0,0}` for ipv4 addrs"
def str2ip(str) do
case :inet_parse:address(str) do
{:ok, ip = {_, _, _, _}} -> ip
{:error, _} -> nil
end
end
end
# config.exs
config :my_app,
port: {:system, "MY_IP", {127,0,0,1}, {Mine.Ip, :str2ip}
```
If you need even more control β say, the
source of your config isnβt the system env, but a file
in a directory, which is more secure in some use
cases β you can use the deferred MFA (module, function,
arguments) form:
```
config :mine,
api_key: {:apply, {File, :read!, ["k.txt"]}}
```
**Nested and arbitrary config** should work.
**Can be extended** to recognize and transform
other kinds of config as well ([`DeferredConfig.populate/2`](DeferredConfig.html#populate/2)),
ie if thereβs a pattern like βsystem tuplesβ that you
wanted to support, and `{:apply, mfa}` was bad UX.
If you have another use case that this doesnβt cover,
please file an issue or reach out to github.com/mrluc
### Limitations
Note that this only applies to **one OTP appβs config.**
We canβt (and shouldnβt try to) monkey-patch every appβs
config; they all start up at different times.
This limitation applies to all approaches to runtime
config except `REPLACE_OS_VARS`.
Rationale
------------
Mix configs donβt always work like users would
like when they build releases, whether with relx, exrm,
distillery, or something else.
There are 3 approaches weβll look at to identify pain points:
1. `REPLACE_OS_VARS` for releases
2. `{:system, ...}` tuples for deferred config
3. Other runtime config libraries
### 1) REPLACE\_OS\_VARS is for releases only
The best-supported method
of injecting run-time configuration β running the release
with `REPLACE_OS_VARS` or `RELX_REPLACE_OS_VARS`, supported
by `distillery`, `relx` and `exrm` β will result in
config like the following:
```
config :my_app, field: "${SOME_VAR}"
```
That works in **all your config, for all apps you configure**,
even if the app doesnβt do anything particular to support it.
Drawbacks of `REPLACE_OS_VARS`
* It only works when running a release.
Otherwise, your `DB_URL` will literally be `"${DB_URL}"`.
* It only gives you string values. Some libs will require
that eg `PORT` be a number.
Neither is a show-stopper *by any means*, but itβs
a small complication β¦ shared users of thousands of
libraries.
### 2) `{:system, ...}` tuples have inconsistent support
Apps that want to allow
run-time configuration from Mix configs (which you could
argue is βall of themβ) should be configurable
with lazy values, which can be filled **on startup of
that application, before they are used**.
What should those lazy values look like? Many libraries have
settled on so-called βsystem tuplesβ, like:
```
config :someapp,
field: {:system, "ENV_VAR_NAME", "default value"}
```
**The downside**: that approach requires every
library author to recognize and support that kind
of tuple.
Some big libraries do! However, it can be a pain to add
support for that kind of config consistently, converting
data types appropriately, for all configurable options in
your app. (A small pain, spread over many libraries).
This library automates that pattern.
### 3) Other runtime config libs use special config files and/or access methods
There are many other libs for config, most of which also
deal with runtime config:
* [:confex](https://hexdocs.pm/confex)
* [:flasked](https://hexdocs.pm/flasked)
* [:env\_config](https://hexdocs.pm/env_config)
* [:config\_ext](https://hexdocs.pm/config_ext)
* [libex\_config](https://hex.pm/packages/libex_config)
* [:configparser](https://hexdocs.pm/configparser_ex)
* [:config](https://hexdocs.pm/config)
* [:spellbook](https://hex.pm/packages/spellbook)
They solve a wide variety of config-related problems.
However, these **all** introduce their own methods for
accessing Application config, and other complexity
as well (mappings, config files, etc).
We avoid that, by doing a replacing walk on the
appβs config at startup.
βWhen should I REPLACE\_OS\_VARS?β
-------------------------------------
Always, but not always because of app config!
For injecting config, it has the limitations
mentioned above in βRationale.β
* For config: **if** you need to configure many libraries that donβt
support deferred config, **and** what you want to configure
can be a string (`DB_URL`, for instance) β¦ in
that case, maybe a release-only config is a good option.
But you should probably use `REPLACE_OS_VARS`
(or `RELX_REPLACE_OS_VARS`), because it **also**
allows **interpolation in `vm.args`**.
* That lets you drive node short/longnames in releases with env vars.
Which can be important when eg you donβt know the node
IP for a release at compile-time.
* Itβs nice that the same approach for vm.args templating
works across release builders.

if(localStorage.getItem('night-mode')) document.body.className += ' night-mode';
DeferredConfig v0.1.1
DeferredConfig
======================================
Seamlessly add runtime config to your library, with the
βsystem tuplesβ or the `{m,f,a}` patterns.
Seamlessly?
===========
In your application startup, add the following line:
```
defmodule Mine.Application do
def start(_type, _args) do
DeferredConfig.populate(:mine) # <-- this one
...
end
end
```
Where `:mine` is the name of your OTP app.
Now you and users of your app or lib can configure
as follows, and itβll work β regardless of if theyβre
running it from iex, or a release with env vars set:
```
config :mine,
# string from env var, or `nil` if missing.
port1: {:system, "PORT"},
# string from env var |> integer; `nil` if missing.
port2: {:system, "PORT", {String, :to_integer}},
# string from env var, or "4000" as default.
port3: {:system, "PORT", "4000"},
# converts env var to integer, or 4000 as default.
port4: {:system, "PORT", 4000, {String, :to_integer}}
```
**Accessing config does not change.**
Since you can use arbitrary transformation functions,
you can do advanced transformations if you need to:
```
# lib/mine/ip.ex
defmodule Mine.Ip do
@doc ":inet_res uses `{0,0,0,0}` for ipv4 addrs"
def str2ip(str) do
case :inet_parse:address(str) do
{:ok, ip = {_, _, _, _}} -> ip
{:error, _} -> nil
end
end
end
# config.exs
config :my_app,
port: {:system, "MY_IP", {127,0,0,1}, {Mine.Ip, :str2ip}
```
See `README.md` for explanation of rationale.
**TL;DR:** `REPLACE_OS_VARS` is string-only and release-only,
and `{:system, ...}` support among libraries is spotty
and easy to get wrong in ways that bite your users
come release time. This library tries to make it easier
to do the right thing with 1 LOC. Other libraries add special
config files and/or special config accessors, which
is more complex than necessary.

A hastily constructed replacing walk for use
with [`DeferredConfig`](DeferredConfig.html); not
very performant, but for transforming data
in options and config, can be convenient.
Summary

[Functions](#functions)
------------------------
[walk(m, recognize, transform)](#walk/3)
Recursive replacing walk that uses `recognize` and
`transform` functions to return a transformed version
of arbitrary data
Functions
============
walk(m, recognize, transform)
Recursive replacing walk that uses `recognize` and
`transform` functions to return a transformed version
of arbitrary data.
```
iex> ReplacingWalk.walk [1, 2, 3], &(&1 == 2), &(&1 * &1)
[1,4,3]
iex> ReplacingWalk.walk( [1, [2, [3, 2]]],
...> &(&1 == 2),
...> &(&1 * &1)
...> )
[1,[4, [3, 4]]]
```
It works for Maps:
```
iex> ReplacingWalk.walk %{2 => 1, 1 => 2}, &(&1 == 2), &(&1 * &1)
%{4 => 1, 1 => 4}
```
Structs in general are considered as leaf nodes; we support
structs that implement Enumerable, but \*\*currently we expect
their [`Enumerable`](https://hexdocs.pm/elixir/Enumerable.html) implementation to work like a Map.
If you feed this an Enumerable struct that doesnβt iterate
like Map β ie, doesnβt iterate over `{k, v}` β it will die.
(See an example in tests).
We may change that behavior in the future β either removing
support for arbitrary Enumerables, or provision another protocol
that can be implemented to make a data type replacing-walkable.
Created quickly for
`:deferred_config`, so itβs probably got some holes;
tests that break it are welcome.

===============================
**This is the end-user API for pyplot.**See the matplotlib.plot docs at:
<http://matplotlib.org/api/pyplot_api.html>
**Most of these functions are UNTESTED. I know. That's terrible. But you can test them by using them! Then, if they don't work, open an issue on the github:**<https://github.com/MaxStrange/expyplot/issues>
**Or better yet, you could write some tests or a patch and open a pull request!**Also, since the return values are simply the string representations of whatever was returned to the python server, all of the return values
will need to be converted into actual Elixir datastructures. I would love to get around to changing this behavior in the future, but for now, it is
as it is. **This also means that numpy arrays that are returned are likely to be truncated**.
This documentation is mostly just copied from the matplotlib.plot docs, and much of it isnβt translated to Elixir like it should be.

```
axis\_set(v, kwargs \\ [])

```
Expyplot.Plot.axvline(x: 1)
```
* Draw a default vline at *x* = 0.5 that spans the middle half of the yrange
```
Expyplot.Plot.axvline(x: 0.5, ymin: 0.25, ymax: 0.75)
```
axvspan(xmin, xmax, opts \\ [ymin: 0, ymax: 1, hold: nil], kwargs \\ [])
Add a vertical span (rectangle) across the axes.
Draw a vertical span (rectangle) from xmin to xmax. With the default values of ymin = 0 and ymax = 1. This always spans the yrange,

coords: 0=bottom, 0.5=middle, 1.0=top but the y location is in data coordinates.
Examples
--------
Draw a vertical, green, translucent rectangle from x = 1.25 to x = 1.55 that spans the yrange of the axes.

Recursively find all Artist instances contained in self.
flag()
Set the default colormap to flag and apply to current image if any.
gca(kwargs \\ [])
Get the current Axes instance on the current figure matching the given keyword args, or create one.
gcf()
Get a reference to the current figure.
gci()
Get the current colorable artist. Specifically, returns the current ScalarMappable instance (image or patch collection), or βNothingβ if no
images or patch collections have been defined. The commands imshow() and figimage() create Image instances, and the commands
pcolor() and scatter() create Collection instances. The current image is an attribute of the current axes, or the nearest earlier axes
in the current figure that contains an image.
get\_current\_fig\_manager()
get\_figlabels()
Return a list of existing figure labels.
get\_fignums()
Return a list of existing figure numbers.

Get a sorted list of all of the plotting commands.
ginput(opts \\ [], kwargs \\ [])
This will wait for *n* clicks from the user and return a list of the coordinates of each click.
If *timeout* is zero or negative, does not timeout.
If *n* is zero or negative, accumulated clicks until a middle click (or potentially both mouse buttons at once) terminates the input.
Right clicking cancels last input.
The buttons used for the various actions (adding points, removing points, terminating the inputs) can be overriden via the arguments
*mouse\_add, mouse\_pop* and *mouse\_stop*, that give the associated mouse button: 1 for left, 2 for middle, 3 for right.The keyboard can also be used to select points in case your mouse does not have one or more of the buttons. The delete and backspace
keys act like right clicking (i.e., remove last point), the enter key terminates input and any other key (not already used by the window
manager) selects a point.
gray()
Set the default colormap to gray and apply to current image if any.
grid(opts \\ [b: nil, which: :major, axis: :both], kwargs \\ [])
Turn the axes grids on or off.
Set the axes grids on or off; *b* is a boolean. (For MATLAB compatibility, *b* may also be an atom :on or :off.)

Make a hexagonal binning plot.
Make a hexagonal binning plot of *x* versus *y*, where *x, y* are 1-D sequences of the same length, *N*. If *C* is
nil (the default), this is a histogram of the number of occurrences of the observations at (x[i], y[i]).
If *C* is specified, it specifies values at the coordinate (x[i], y[i]). These values are accumulated for each hexagonal bin and then reduced
according to *reduce\_C\_function*, which defaults to numpyβs mean function (np.mean). (If *C* is specified, it must also be a 1-D sequence
of the same length as *x* and *y*.)
hist(x, opts \\ [bins: nil, range: nil, normed: false, weights: nil, cumulative: false, bottom: nil, histtype: :bar, align: :mid, orientation: :vertical, rwidth: nil, log: false, color: nil, label: nil, stacked: false, hold: nil, data: nil], kwargs \\ [])
Plot a histogram.
Compute and draw the histogram of *x*. The return value is a tuple (*n, bins, patches*) or (*[n0, n1, ...], bins, [patches0, patches1, ...]*)
if the input contains multiple data.
Multiple data can be provided via *x* as a list of datasets of potentially different length, or as a 2-D ndarray in which each column is a dataset.
Note that the ndarray form is transposed relative to the list form.
Masked arrays are not supported at present.
hist2d(x, y, opts \\ [bins: 10, range: nil, normed: false, weights: nil, cmin: nil, cmax: nil, hold: nil, data: nil], kwargs \\ [])
Make a 2D histogram plot.

Set the default colormap to hot and apply to current image if any.
hsv()
Set the default colormap to hsv and apply to current image if any.
imread(opts \\ [], kwargs \\ [])
Read an image from a file into an array.
*fname* may be a string path, or a valid URL.If *format* is provided, will try to read file of that type, otherwise the format is deduced from the filename. If nothing can be deduced, PNG
is tried.
Return value is a numpy.array **But in expyplot, this will return a string, and it probably wonβt work**. For grayscale images, the return array is MxN.
For RGB images, the return value is MxNx4.
matplotlib can only read PNGs natively, but if PIL is installed, it will use it to load the image and return an array (if possible) which can
be used with imshow(). Note, URL strings may not be compatible with PIL. Check the PIL documentation for more information.
imsave(opts \\ [], kwargs \\ [])
Save an array as an image file.
The output formats available depend on the backend being used.

figure window is that of the array, unless this would make an excessively short or narrow figure.
Tick labels for the xaxis are placed on top.
minorticks\_off()
Remove minor ticks from the current plot.
nipy\_spectral()
Set the default colormap to nipy\_spectral and apply to current image if any.
pause(interval)
Pause for *interval* seconds.
If there is an active figure it will be updated and displayed, and the GUI event loop will run during the pause.

Plot a pie chart.
Make a pie chart of array x. The fractional area of each wedge is given by x / sum(x). If sum(x) <= 1, then the values of x give the fractional
area directly and the array will not be normalized. The wedges are plotted counterclockwise, by default starting from the x-axis.

plasma()
Set the default colormap to plasma and apply to current image if any.
plot(opts \\ [], kwargs \\ [])
Plot lines and/or markers to the Axes. *args* is a variable length argument, allowing for multiple *x, y* pairs with an optional format string.
Each of the following is legal:
```
x = 1..10 |> Enum.to_list
y = 11..20 |> Enum.to_list
Expyplot.Plot.plot([x, y]) # plot x and y using default line style and color
Expyplot.Plot.plot([x, y, "bo"]) # plot x and y using blue circle markers
Expyplot.Plot.plot([y]) # plot y using x as index array 0..N-1
Expyplot.Plot.plot([y, "r+"]) # ditto, but with red plusses
x2 = 1..5 |> Enum.to_list
y2 = 3..7 |> Enum.to_list
Expyplot.Plot.plot([x, y, "g^", x2, y2, "g-"])
```
Due to the differences between function signatures in Python and Elixir, the typical usage of this function is a little different than what you would
expect:
```
iex> Expyplot.Plot.plot([[1, 2, 3, 4, 5]])
or
iex> Expyplot.Plot.plot([1..5])
```
Notice the nesting of the list or range.

Bodyguard protects the context boundaries of your application. πͺ
Version 2 was built from the ground-up to integrate nicely with Phoenix contexts. Authorization callbacks are implemented directly on contexts, so permissions can be checked from controllers, views, sockets, tests, and even other contexts.
The [`Bodyguard.Policy`](Bodyguard.Policy.html) behaviour is implemented with a single required callback. Additionally, the [`Bodyguard.Schema`](Bodyguard.Schema.html) behaviour provides a convention for limiting query results per-user.
This is an all-new API, so refer to [the `1.x` branch](https://github.com/schrockwell/bodyguard/tree/1.x) for the earlier readme.
* [Docs](https://hexdocs.pm/bodyguard/) β complete documentation
* [Hex](https://hex.pm/packages/bodyguard)
* [GitHub](https://github.com/schrockwell/bodyguard)
Quick Example
----------------
Define authorization rules directly in the context module:
```
# lib/my\_app/blog/blog.ex
defmodule MyApp.Blog do
@behaviour Bodyguard.Policy
# Admins can update anything
def authorize(:update\_post, %{role: :admin} = \_user, \_post), do: :ok
# Users can update their owned posts
def authorize(:update\_post, %{id: user\_id} = \_user, %{user\_id: user\_id} = \_post), do: :ok
# Otherwise, denied
def authorize(:update\_post, \_user, \_post), do: :error
end
# lib/my\_app\_web/controllers/post\_controller.ex
defmodule MyAppWeb.PostController do
use MyAppWeb, :controller
def update(conn, %{"id" => id, "post" => post\_params}) do
user = conn.assigns.current\_user
post = MyApp.Blog.get\_post!(id)
with :ok <- Bodyguard.permit(MyApp.Blog, :update\_post, user, post),
{:ok, post} <- MyApp.Blog.update\_post(post, post\_params)
do
redirect(conn, to: post\_path(conn, :show, post))
end
end
end
```
Policies
-----------
To implement a policy, add `@behaviour Bodyguard.Policy` to a context, then define `authorize(action, user, params)` callbacks, which must return:
* `:ok` or `true` to permit an action
* `:error`, `{:error, reason}`, or `false` to deny an action
Don't use these callbacks directly - instead, go through [`Bodyguard.permit/4`](Bodyguard.html#permit/4). This will convert any keyword-list `params` into a map, and will coerce the callback result into a strict `:ok` or `{:error, reason}` result. The default failure `reason` is `:unauthorized` unless specified otherwise in the callback.
Also provided are [`Bodyguard.permit?/4`](Bodyguard.html#permit?/4) (returns a boolean) and [`Bodyguard.permit!/5`](Bodyguard.html#permit!/5) (raises [`Bodyguard.NotAuthorizedError`](Bodyguard.NotAuthorizedError.html) on failure).
```
# lib/my\_app/blog/blog.ex
defmodule MyApp.Blog do
@behaviour Bodyguard.Policy
alias \_\_MODULE\_\_
# Admin users can do anything
def authorize(\_, %Blog.User{role: :admin}, \_), do: true
# Regular users can create posts
def authorize(:create\_post, \_, \_), do: true
# Regular users can modify their own posts
def authorize(action, %Blog.User{id: user\_id}, %Blog.Post{user\_id: user\_id})
when action in [:update\_post, :delete\_post], do: true
# Catch-all: deny everything else
def authorize(\_, \_, \_), do: false
end
```
If you prefer more structure, define a dedicated policy module outside of the context, and use `defdelegate`:
```
# lib/my\_app/blog/blog.ex
defmodule MyApp.Blog do
defdelegate authorize(action, user, params), to: MyApp.Blog.Policy
end
# lib/my\_app/blog/policy.ex
defmodule MyApp.Blog.Policy do
@behaviour Bodyguard.Policy
def authorize(action, user, params), do: # ...
end
```
Controllers
--------------
Phoenix 1.3 introduces the `action_fallback` controller macro. This is the recommended way to deal with authorization failures. The fallback controller will handle `{:error, reason}` authorization failures.
If you are using the [`Bodyguard.Plug.Authorize`](Bodyguard.Plug.Authorize.html) plug, then you must use its `:fallback` option instead, since the plug pipeline will be halted before the controller action is called.
Typically, authorization failure results in `{:error, :unauthorized}`. If you wish to deny access without leaking the existence of a particular resource, consider returning `{:error, :not_found}` instead, and handle it separately in the fallback controller.
See the section "Overriding `action/2` for custom arguments" in [the Phoenix.Controller docs](https://hexdocs.pm/phoenix/Phoenix.Controller.html) for a clean way to pass in the `user` to each action.
```
# lib/my\_app\_web/controllers/fallback\_controller.ex
defmodule MyAppWeb.FallbackController do
use MyAppWeb, :controller
def call(conn, {:error, :unauthorized}) do
conn
|> put\_status(:forbidden)
|> put\_view(MyAppWeb.ErrorView)
|> render(:"403")
end
end
```
###
Where Should I Perform Checks?
Bodyguard doesn't make any assumptions about where authorization checks are performed. You can do it before calling into the context, or within the context itself. There is a good discussion of the tradeoffs [here](https://dockyard.com/blog/2017/08/01/authorization-for-phoenix-contexts).
Plugs
--------
* [`Bodyguard.Plug.Authorize`](Bodyguard.Plug.Authorize.html) β perform authorization in the middle of a pipeline
This plug's config utilizes callback functions called getters, which are 1-arity functions that
accept the `conn` and return the appropriate value.
```
# lib/my\_app\_web/controllers/post\_controller.ex
defmodule MyAppWeb.PostController do
use MyAppWeb, :controller
# Fetch the post and put into conn assigns
plug :get\_post when action in [:show]
# Do the check
plug Bodyguard.Plug.Authorize,
policy: MyApp.Blog.Policy,
action: {Phoenix.Controller, :action\_name},
user: {MyApp.Authentication, :current\_user},
params: {\_\_MODULE\_\_, :extract\_post},
fallback: MyAppWeb.FallbackController
def show(conn, \_) do
# Already assigned and authorized
render(conn, "show.html")
end
defp get\_post(conn, \_) do
assign(conn, :post, MyApp.Posts.get\_post!(conn.params["id"]))
end
# Helper for the Authorize plug
def extract\_post(conn), do: conn.assigns.posts
end
```
See the docs for more information about configuring application-wide defaults for the plug.
Schema Scopes
----------------
Bodyguard also provides the [`Bodyguard.Schema`](Bodyguard.Schema.html) behaviour to query which items a user can access. Implement it directly on schema modules.
```
# lib/my\_app/blog/post.ex
defmodule MyApp.Blog.Post do
import Ecto.Query, only: [from: 2]
@behaviour Bodyguard.Schema
def scope(query, %MyApp.Blog.User{id: user\_id}, \_) do
from ms in query, where: ms.user\_id == ^user\_id
end
end
```
To leverage scopes, the [`Bodyguard.scope/4`](Bodyguard.html#scope/4) helper function (not the callback!) can infer the type of a query and automatically defer to the appropriate callback.
```
# lib/my\_app/blog/blog.ex
defmodule MyApp.Blog do
def list\_user\_posts(user) do
MyApp.Blog.Post
|> Bodyguard.scope(user) # <-- defers to MyApp.Blog.Post.scope/3
|> where(draft: false)
|> Repo.all
end
end
```
Configuration
----------------
Here is the default library config.
```
config :bodyguard,
# The second element of the {:error, reason} tuple returned on auth failure
default\_error: :unauthorized
```
Testing
----------
Testing is pretty straightforward β use the [`Bodyguard`](Bodyguard.html) top-level API.
```
assert :ok == Bodyguard.permit(MyApp.Blog, :successful\_action, user)
assert {:error, :unauthorized} == Bodyguard.permit(MyApp.Blog, :failing\_action, user)
assert Bodyguard.permit?(MyApp.Blog, :successful\_action, user)
refute Bodyguard.permit?(MyApp.Blog, :failing\_action, user)
error = assert\_raise Bodyguard.NotAuthorizedError, fun ->
Bodyguard.permit(MyApp.Blog, :failing\_action, user)
end
assert %{status: 403, message: "not authorized"} = error
```
Installation
---------------
1. Add `:bodyguard` to your list of dependencies:
```
# mix.exs
def deps do
[
{:bodyguard, "~> 2.4"}
]
end
```
2. Create an error view for handling `403 Forbidden`.
```
# lib/my\_app\_web/views/error\_view.ex
defmodule MyAppWeb.ErrorView do
use MyAppWeb, :view
def render("403.html", \_assigns) do
"Forbidden"
end
end
```
3. Wire up a [fallback controller](#controllers) to render this error view on `{:error, :unauthorized}`.
4. Add `@behaviour Bodyguard.Policy` to contexts that require authorization, and implement `authorize/3` callbacks.
5. (Optional) Add `@behaviour Bodyguard.Schema` on schemas available for user-scoping, and implement `scope/3` callbacks.
6. (Optional) Edit `my_app_web.ex` and add `import Bodyguard` to controllers, views, channels, etc.

Filter a query down to user-accessible items.
The `query` is introspected by Bodyguard in an attempt to automatically
determine the schema type. To succeed, `query` must be an atom (schema
module name), an `Ecto.Query`, or a list of structs.
This function exists primarily as a helper to `import` into a context and
gain access to scoping for all schemas.
```
defmodule MyApp.Blog do
import Bodyguard
def list\_user\_posts(user) do
Blog.Post
|> scope(user) # <-- defers to MyApp.Blog.Post.scope/3
|> where(draft: false)
|> Repo.all
end
end
```
If `params` is a keyword list, it is converted to a map before passing down
to the [`Bodyguard.Schema.scope/3`](Bodyguard.Schema.html#c:scope/3) callback. Otherwise, `params` is not

[View Source](https://github.com/schrockwell/bodyguard/blob/v2.4.2/lib/bodyguard/action.ex#L1 "View Source")
=================================================================================================================================================
Execute authorized actions in a composable way.
An Action can be built up over the course of a request, providing a means to
specify authorization parameters in the steps leading up to actually
executing the job.
When authorization fails, there is an opportunity to handle it using a
fallback function before returning the final result.
Authorization is performed by deferring to a [`Bodyguard.Policy`](Bodyguard.Policy.html).
#### Fields
* `:context` β Context for the action
* `:policy` β Implementation of [`Bodyguard.Policy`](Bodyguard.Policy.html) behaviour; defaults to the `:context`
* `:user` β The user to authorize
* `:name` β The name of the authorized action
* `:auth_run?` β If an authorization check has been performed
* `:auth_result`Β β Result of the authorization check
* `:authorized?` β If authorization has succeeded (default `false`)
* `:job` β Function to execute if authorization passes; signature `job(action)`
* `:fallback` β Function to execute if authorization fails; signature `fallback(action)`
* `:assigns` β Generic parameters along for the ride
#### Controller Example
```
defmodule MyApp.Web.PostController do
use MyApp.Web, :controller
import Bodyguard.Action
alias MyApp.Blog
action\_fallback MyApp.FallbackController
plug Bodyguard.Plug.BuildAction, context: Blog, user: &get\_current\_user/1
def index(conn, \_) do
run conn.assigns.action, fn(action) ->
posts = Blog.list\_posts(action.user)
render(conn, "index.html", posts: posts)
end
end
defp get\_current\_user(conn) do
# ...
end
end
```
#### Verbose Example
```
import Bodyguard.Action
alias MyApp.Blog
act(Blog)
|> put\_user(get\_current\_user())
|> put\_policy(Blog.SomeSpecialPolicy)
|> assign(:drafts, true)
|> authorize(:list\_posts)
|> put\_job(fn action ->
Blog.list\_posts(action.user, drafts\_only: action.assigns.drafts)
end)
|> put\_fallback(fn \_action -> {:error, :not\_found} end)

=================================================================================================================================================================
Perform authorization in a Plug pipeline.
Options
----------
* `:policy` *required* - the policy (or context) module
* `:action` *required* - the action, or a getter
* `:user` - the user getter
* `:params` - the params, or a getter, to pass to the authorization callbacks
* `:fallback` - a fallback controller or plug to handle authorization
failure. If specified, the plug is called and then the pipeline is
`halt`ed. If not specified, then [`Bodyguard.NotAuthorizedError`](Bodyguard.NotAuthorizedError.html) raises
directly to the router.
###
Option Getters
The options `:action`, `:user`, and `:params` can accept getter functions that are either:
* an anonymous 1-arity function that accepts the `conn` and returns a value
* a `{module, function_name}` tuple specifying an existing function with that same signature
###
Default Plug Options
You can provide default options for this plug by simply wrapping your own plug around it.
For example, if you're using Phoenix with Pow for authentication, you might want to specify:
```
defmodule MyAppWeb.Authorize do
def init(opts) do
opts
|> Keyword.put\_new(:action, {Phoenix.Controller, :action\_name})
|> Keyword.put\_new(:user, {Pow.Plug, :current\_user})
|> Bodyguard.Plug.Authorize.init()
end
def call(conn, opts) do
Bodyguard.Plug.Authorize.call(conn, opts)
end
end
```
Examples
-----------
```
# Raise on failure
plug Bodyguard.Plug.Authorize,
policy: MyApp.Blog,
action: &action\_name/1,
user: {MyApp.Authentication, :current\_user}
# Fallback on failure
plug Bodyguard.Plug.Authorize,
policy: MyApp.Blog,
action: &action\_name/1,
user: {MyApp.Authentication, :current\_user},
fallback: MyAppWeb.FallbackController
# Params as a function
plug Bodyguard.Plug.Authorize,
policy: MyApp.Blog,
action: &action\_name/1,
user: {MyApp.Authentication, :current\_user},
params: &get\_params/1

Where authorization rules live.
Typically the callbacks are designed to be used by [`Bodyguard.permit/4`](Bodyguard.html#permit/4) and
are not called directly.
The only requirement is to implement the [`authorize/3`](#c:authorize/3) callback:
```
defmodule MyApp.MyContext do
@behaviour Bodyguard.Policy
def authorize(action, user, params) do
# Return :ok or true to permit
# Return :error, {:error, reason}, or false to deny
end
end
```
To perform authorization checks, use [`Bodyguard.permit/4`](Bodyguard.html#permit/4) and friends:
```
with :ok <- Bodyguard.permit(MyApp.MyContext, :action\_name, user, param: :value) do
# ...
end
if Bodyguard.permit?(MyApp.MyContext, :action\_name, user, param: :value) do
# ...
end
Bodyguard.permit!(MyApp.MyContext, :action\_name, user, param: :value)
```
If you want to define the callbacks in another module, you can use
`defdelegate`:
```
defmodule MyApp.MyContext do
defdelegate authorize(action, user, params), to: Some.Other.Policy
end

Callback to authorize a user's action.
To permit an action, return `:ok` or `true`. To deny, return `:error`,
`{:error, reason}`, or `false`.
The `action` is whatever user-specified contextual action is being authorized.
It bears no intrinsic relationship to a controller action, and instead should
share a name with a particular function on the context.

===========================================================================================================================================================
Specify user-accessible items.
The callbacks are designed to live within your schemas, hidden from the
context boundaries of your application.
All you have to do is implement the [`scope/3`](#c:scope/3) callback on your schema.
What "access" means is up to you, and can be customized on a case-by-case
basis via `params`.
Typically the callbacks are designed to be used by [`Bodyguard.scope/4`](Bodyguard.html#scope/4) and
are not called directly.
If you want to use separate module for scoping, you can use `defdelegate`:
```
defmodule MyApp.MyModel.MySchema do
defdelegate scope(query, user, params), to: Some.Other.Scope
end

This plug helps to manage multiple API versions based on request and response gateways. This is an awesome practice to hide your backward compatibility. It allows to have your code in a latest possible version, without duplicating controllers or models.
Inspired by Stripe API. Read more at [MOVE FAST, DONβT BREAK YOUR API](http://amberonrails.com/move-fast-dont-break-your-api/) or [API versioning](https://stripe.com/blog/api-versioning).
Goals
--------
* reduce changes required to support multiple API versions;
* provide a way to test and schedule API version releases;
* to have minimum dependencies and low performance hit;
* to be flexible enough for most of projects to adopt it.
Adapters
-----------
Multiverse allows you to use a custom adapter which can, for eg.:
* store consumer version upon his first request and re-use it as default each time consumer is using your API, eliminating need of passing version headers for them. Change this version when consumer has explicitly set it;
* use *other than ISO date* version types, eg. incremental counters (`v1`, `v2`);
* handle malformed versions by responding with JSON errors.
Default adapter works with ISO-8601 date from `x-api-version` header (configurable). For malformed versions it would log a warning and fallback to the current date.
Also, it allows to use channel name instead of date, where:
* `latest` channel would fallback to the current date;
* `edge` channel would disable all changes altogether.
Channels allow you to plan version releases upfront and test them without affecting users,
just set future date for a change and pass it explicitly or use `edge` channel to test latest
application version.
Installation
---------------
The package (take look at [hex.pm](https://hex.pm/packages/multiverse)) can be installed as:
1. Add `multiverse` to your list of dependencies in `mix.exs`:
```
def deps do
[{:multiverse, "~> 1.1.0"}]
end
```
2. Make sure that `multiverse` is available at runtime in your production:
```
def application do
[applications: [:multiverse]]
end
```
How to use
-------------
1. Insert this plug into your API pipeline (in your `router.ex`):
```
pipeline :api do
plug :accepts, ["json"]
plug :put_secure_browser_headers
plug Multiverse
end
```
2. Define module that handles change
```
defmodule AccountTypeChange do
@behaviour Multiverse.Change
def handle_request(%Plug.Conn{} = conn) do
# Mutate your request here
IO.inspect "AccountTypeChange.handle_request applied to request"
conn
end
def handle_response(%Plug.Conn{} = conn) do
# Mutate your response here
IO.inspect "AccountTypeChange.handle_response applied to response"
conn
end
end
```
3. Enable the change:
```
pipeline :api do
plug :accepts, ["json"]
plug :put_secure_browser_headers
plug Multiverse, gates: %{
~D[2016-07-21] => [AccountTypeChange]
}
end
```
4. Send your API requests with `X-API-Version` header with version lower or equal to `2016-07-20`.
###
Overriding version header
You can use any version headers by passing option to Multiverse:
```
pipeline :api do
plug :accepts, ["json"]
plug :put_secure_browser_headers
plug Multiverse,
version_header: "x-my-version-header",
gates: %{
~D[2016-07-21] => [AccountTypeChange]
}
end
```
###
Using custom adapters
You can use your own adapter which implements [`Multiverse.Adapter`](Multiverse.Adapter.html) behaviour:
```
pipeline :api do
plug :accepts, ["json"]
plug :put_secure_browser_headers
plug Multiverse,
adapter: MyApp.SmartMultiverseAdapter,
gates: %{
~D[2016-07-21] => [AccountTypeChange]
}
end
```
Structuring your tests
-------------------------
1. Split your tests into versions:
$ ls -l test/acceptance
total 0
drwxr-xr-x 2 andrew staff 68 Aug 1 19:23 AccountTypeChange
drwxr-xr-x 2 andrew staff 68 Aug 1 19:24 OlderChange
2. Avoid touching request or response in old tests. Create API gates and matching folder in acceptance tests.
Other things you might want to do
------------------------------------
1. Store Multiverse configuration in `config.ex`:
```
use Mix.Config
config :multiverse, MyApp.Endpoint,
gates: %{
~D[2016-07-21] => [AccountTypeChange]
}
```
```
plug Multiverse, endpoint: __MODULE__
```
2. Generate API documentation from changes `@moduledoc`βs.
3. Other awesome stuff. Open an issue and tell me about it! :).

Resolve version by string value from request header.
This callback can be used to set named channels for API versions,
for eg. `latest` header value could be resolved to current date and
`edge` to the most recent defined version.
Also, it is responsible for casting string value to adapter-specific
version type and handling possible errors.
You can terminate connection if you want to return error without
further processing of the request.

Multiverse.Adapters.ISODate
===============================================
Adapter that fetches ISO-8601 date from request header and `Elixir.Date`
to resolve changes that must be applied to the connection.
Current date is used as fallback when:
* version header is not present in request;
* value of a version header is malformed (and warning is logged);
* `latest` channel is used instead of date.
When `edge` channel is used instead of date, no changes are applied to the connection.

Unless you're developing an Membrane Element it's unlikely that you need to use this package directly in your app, as normally it is going to be fetched as a dependency of any element that operates on RTP packets.
However, if you are developing an Element or need to add it due to any other reason, just add the following line to your `deps` in the `mix.exs` and run [`mix deps.get`](https://hexdocs.pm/mix/Mix.Tasks.Deps.Get.html).

===================================================================================================================
[](https://github.com/whitfin/sleeplocks/actions) [](https://hex.pm/packages/sleeplocks) [](https://hexdocs.pm/sleeplocks/)
This library is designed to provide simple locking mechanisms in Erlang/Elixir, similar to
how spinlocks work in other languages - except using messages to communicate locking.
This is useful for libraries which require lock synchronization, without having to roll your
own (however simple). Locks can be held by arbitrary numbers of process, making it possible
to implement various throttling mechanisms.
Best of all, this library is tiny! It builds upon basic OTP principles to implement lock
behaviour via simple processes and message passing.

```
% create a new single lock (with a name)
1> sleeplocks:new(1, [{name, {local, my\_lock}}]).
{ok,<0.179.0>}
% take ownership of the lock
2> sleeplocks:acquire(my\_lock).

[elixir](#elixir)
Elixir
```
# create a new single lock (with a name)
iex(1)> :sleeplocks.new(1, [ name: :my\_lock ])
{:ok, #PID<0.179.0>}
# take ownership of the lock
iex(2)> :sleeplocks.acquire(:my\_lock)
:ok
# release the current hold on a lock
iex(3)> :sleeplocks.release(:my\_lock)
:ok
# attempt to acquire a lock (which will succeed)
iex(4)> :sleeplocks.attempt(:my\_lock)
:ok
# now that it's taken, other attempts will fail
iex(5)> :sleeplocks.attempt(:my\_lock)
{:error, :unavailable}
# release the lock again
iex(6)> :sleeplocks.release(:my\_lock)
:ok
# handle acquisition and locking automatically
iex(7)> :sleeplocks.execute(:my\_lock, fn ->
iex(7)> 3
iex(7)> end)
3
```
[examples](#examples)
Examples
--------------------------------
This example is in Elixir, but it should be fairly understandable for those coming from
both languages. It simply spawns 6 processes which each attempt to hold a lock for 10
seconds. As the lock is created with only 2 slots, this runs for 30 seconds and 2 of our
spawned tasks can hold the lock at any given time.
```
# First create a new lock, with 2 slots only
{:ok, ref} = :sleeplocks.new(2)
# Then spawn 6 tasks, which each just sleep for 10 seconds
# after acquiring the lock. This means that 2 processes will
# acquire a lock and then release after 10 seconds. This
# will repeat 3 times (6 / 2) until 30 seconds are up.
for idx <- 1..6 do
Task.start(fn ->
:sleeplocks.execute(ref, fn ->
IO.puts("Locked #{idx}")
Process.sleep(10\_000)
IO.puts("Releasing #{idx}")
end)
end)
end
```

=================================================================================================================================================
BEAM friendly spinlocks for Elixir/Erlang.
This module provides a very simple API for managing locks inside a BEAM instance. It's modeled on spinlocks, but works through message passing rather than loops. Locks can have multiple slots to enable arbitrary numbers of associated processes. The moment a slot is freed, the next awaiting process acquires the lock.
All of this is done in a simple Erlang process so there's very little dependency, and management is extremely simple.

=========================================================================================================================================================================
VK Strategy for Γberauth.
###
Setup
Create an VK application for you to use.
Register a new application at: [VK devs](https://vk.com/dev) and get the `client_id` and `client_secret`.
Include the provider in your configuration for Ueberauth
```
config :ueberauth, Ueberauth,
providers: [
vk: { Ueberauth.Strategy.VK, [] }
]
```
Then include the configuration for github.
```
config :ueberauth, Ueberauth.Strategy.VK.OAuth,
client_id: System.get_env("VK_CLIENT_ID"),
client_secret: System.get_env("VK_CLIENT_SECRET"),
```
If you havenβt already, create a pipeline and setup routes for your callback handler
```
pipeline :auth do
Ueberauth.plug "/auth"
end
scope "/auth" do
pipe_through [:browser, :auth]
get "/:provider/callback", AuthController, :callback
end
```
Create an endpoint for the callback where you will handle the [`Ueberauth.Auth`](https://hexdocs.pm/ueberauth/0.5.0/Ueberauth.Auth.html) struct
```

You can edit the behaviour of the Strategy by including some options when you register your provider.
You can customize [multiple fields](https://vk.com/dev/auth_sites), such as `default_scope`, `default_display`, `default_state`, `profile_fields`, `uid_field`
```
config :ueberauth, Ueberauth,
providers: [
vk: { Ueberauth.Strategy.VK, [
default_scope: "email,friends,video,offline",
default_display: "popup",
default_state: "secret-state-value",
uid_field: :email
] }
]
```
Default is empty (ββ) which βGrants read-only access to public information (includes public user profile info, public repository info, and gists)β

Polymorphic embeds for Ecto
===============================================================================================================================================
`polymorphic_embed` brings support for polymorphic/dynamic embedded schemas in Ecto.
Ecto's `embeds_one` and `embeds_many` macros require a specific schema module to be specified. This library removes this restriction by
**dynamically** determining which schema to use, based on data to be stored (from a form or API) and retrieved (from the
data source).
[usage](#usage)
Usage
-----------------------
###
[enable-polymorphism](#enable-polymorphism)
Enable polymorphism
Let's say we want a schema `Reminder` representing a reminder for an event, that can be sent either by email or SMS.
We create the `Email` and `SMS` embedded schemas containing the fields that are specific for each of those communication
channels.
The `Reminder` schema can then contain a `:channel` field that will either hold an `Email` or `SMS` struct, by setting
its type to the custom type [`PolymorphicEmbed`](PolymorphicEmbed.html) that this library provides.
Find the schema code and explanations below.
```
defmodule MyApp.Reminder do
use Ecto.Schema
import Ecto.Changeset
import PolymorphicEmbed
schema "reminders" do
field :date, :utc\_datetime
field :text, :string
polymorphic\_embeds\_one :channel,
types: [
sms: MyApp.Channel.SMS,
email: MyApp.Channel.Email
],
on\_type\_not\_found: :raise,
on\_replace: :update
end
def changeset(struct, values) do
struct
|> cast(values, [:date, :text])
|> cast\_polymorphic\_embed(:channel, required: true)
|> validate\_required(:date)
end
end
```
```
defmodule MyApp.Channel.Email do
use Ecto.Schema
import Ecto.Changeset
@primary\_key false
embedded\_schema do
field :address, :string
field :confirmed, :boolean
end
def changeset(email, params) do
email
|> cast(params, ~w(address confirmed)a)
|> validate\_required(:address)
|> validate\_length(:address, min: 4)
end
end
```
```
defmodule MyApp.Channel.SMS do
use Ecto.Schema
@primary\_key false
embedded\_schema do
field :number, :string
end
end
```
In your migration file, you may use the type `:map` for both `polymorphic_embeds_one/2` and `polymorphic_embeds_many/2` fields.
```
add(:channel, :map)
```
[It is not recommended](https://hexdocs.pm/ecto/3.8.4/Ecto.Schema.html#embeds_many/3) to use `{:array, :map}` for a list of embeds.
###
[cast\_polymorphic\_embed-3](#cast_polymorphic_embed-3)
`cast_polymorphic_embed/3`
`cast_polymorphic_embed/3` must be called to cast the polymorphic embed's parameters.
#### Options
* `:required` β if the embed is a required field.
* `:with` β allows you to specify a custom changeset. Either pass an MFA or a function:
```
changeset
|> cast\_polymorphic\_embed(:channel,
with: [
sms: {SMS, :custom\_changeset, ["hello"]},
email: &Email.custom\_changeset/2
]
)
```
###
[polymorphicembed-ecto-type](#polymorphicembed-ecto-type)
PolymorphicEmbed Ecto type
The `:types` option for the [`PolymorphicEmbed`](PolymorphicEmbed.html) custom type contains a keyword list mapping an atom representing the type
(in this example `:email` and `:sms`) with the corresponding embedded schema module.
There are two strategies to detect the right embedded schema to use:
1.
```
[sms: MyApp.Channel.SMS]
```
When receiving parameters to be casted (e.g. from a form), we expect a `"__type__"` (or `:__type__`) parameter
containing the type of channel (`"email"` or `"sms"`).
2.
```
[email: [
module: MyApp.Channel.Email,
identify\_by\_fields: [:address, :confirmed]]]
```
Here we specify how the type can be determined based on the presence of given fields. In this example, if the data
contains `:address` and `:confirmed` parameters (or their string version), the type is `:email`. A `"__type__"`
parameter is then no longer required.
Note that you may still include a `__type__` parameter that will take precedence over this strategy (this could still be
useful if you need to store incomplete data, which might not allow identifying the type).
#### List of polymorphic embeds
Lists of polymorphic embeds are also supported:
```
polymorphic\_embeds\_many :contexts,
types: [
location: MyApp.Context.Location,
age: MyApp.Context.Age,
device: MyApp.Context.Device
],
on\_type\_not\_found: :raise,
on\_replace: :delete
```
#### Options
* `:types` β discussed above.
* `:type_field` β specify a custom type field. Defaults to `:__type__`.
* `:on_type_not_found` β specify what to do if the embed's type cannot be inferred.
Possible values are
+ `:raise`: raise an error
+ `:changeset_error`: add a changeset error
+ `:nilify`: replace the data by `nil`; only for single (non-list) embeds
+ `:ignore`: ignore the data; only for lists of embedsBy default, a changeset error "is invalid" is added.
* `:on_replace` β mandatory option that can only be set to `:update` for a single embed and `:delete` for a list of
embeds (we force a value as the default value of this option for `embeds_one` and `embeds_many` is `:raise`).
###
[displaying-form-inputs-and-errors-in-phoenix-templates](#displaying-form-inputs-and-errors-in-phoenix-templates)
Displaying form inputs and errors in Phoenix templates
The library comes with a form helper in order to build form inputs for polymorphic embeds and display changeset errors.
In the entrypoint defining your web interface (`lib/your_app_web.ex` file), add the following import:
```
def view do
quote do
# imports and stuff
import PolymorphicEmbed.HTML.Form
end
end
```
This provides you with the `polymorphic_embed_inputs_for/3` and `polymorphic_embed_inputs_for/4` functions.
Here is an example form using the imported function:
```
<%= inputs\_for f, :reminders, fn reminder\_form -> %>
<%= polymorphic\_embed\_inputs\_for reminder\_form, :channel, :sms, fn sms\_form -> %>
<div class="sms-inputs">
<label>Number<label>
<%= text\_input sms\_form, :number %>
<div class="error">
<%= error\_tag sms\_form, :number %>
</div>
</div>
<% end %>
<% end %>
```
When using `polymorphic_embed_inputs_for/4`, you have to manually specify the type. When the embed is `nil`, empty fields will be displayed.
`polymorphic_embed_inputs_for/3` doesn't require the type to be specified. When the embed is `nil`, no fields are displayed.
They both render a hidden input for the `"__type__"` field.
###
[displaying-form-inputs-and-errors-in-liveview](#displaying-form-inputs-and-errors-in-liveview)
Displaying form inputs and errors in LiveView
You may use `polymorphic_embed_inputs_for/2` when working with LiveView.
```
<.form
let={f}
for={@changeset}
id="reminder-form"
phx-change="validate"
phx-submit="save"
>
<%= for channel\_form <- polymorphic\_embed\_inputs\_for f, :channel do %>
<%= hidden\_inputs\_for(channel\_form) %>
<%= case get\_polymorphic\_type(channel\_form, Reminder, :channel) do %>
<% :sms -> %>
<%= label channel\_form, :number %>
<%= text\_input channel\_form, :number %>
<% :email -> %>
<%= label channel\_form, :email %>
<%= text\_input channel\_form, :email %>
<% end %>
</.form>
```
Using this function, you have to render the necessary hidden inputs manually as shown above.
###
[get-the-type-of-a-polymorphic-embed](#get-the-type-of-a-polymorphic-embed)
Get the type of a polymorphic embed
Sometimes you need to serialize the polymorphic embed and, once in the front-end, need to distinguish them.
`get_polymorphic_type/3` returns the type of the polymorphic embed:
```
PolymorphicEmbed.get\_polymorphic\_type(Reminder, :channel, SMS) == :sms
```
###
[traverse\_errors-2](#traverse_errors-2)
`traverse_errors/2`
The function `Ecto.changeset.traverse_errors/2` won't include the errors of polymorphic embeds. You may instead use [`PolymorphicEmbed.traverse_errors/2`](PolymorphicEmbed.html#traverse_errors/2) when working with polymorphic embeds.
[features](#features)
Features
--------------------------------
* Detect which types to use for the data being `cast`-ed, based on fields present in the data (no need for a *type* field in the data)
* Run changeset validations when a `changeset/2` function is present (when absent, the library will introspect the fields to cast)
* Support for nested polymorphic embeds
* Support for nested `embeds_one`/`embeds_many` embeds
* Display form inputs for polymorphic embeds in Phoenix templates
* Tests to ensure code quality
[installation](#installation)
Installation
--------------------------------------------
Add `polymorphic_embed` for Elixir as a dependency in your `mix.exs` file:
```
def deps do
[
{:polymorphic\_embed, "~> 3.0.3"}
]
end
```

```
The primary text to be inserted is treated as a snippet.
A snippet can define tab stops and placeholders with `$1`, `$2`
and `${3:foo}`. `$0` defines the final tab stop, it defaults to
the end of the snippet. Placeholders with equal identifiers are linked,
that is typing in one will update others too.

The document close notification is sent from the client to the server when
the document got closed in the client. The document's truth now exists where
the document's uri points to (e.g. if the document's uri is a file uri the
truth now exists on disk). As with the open notification the close notification
is about managing the document's content. Receiving a close notification
doesn't mean that the document was open in an editor before. A close
notification requires a previous open notification to be sent.

======================================================================================================================================================================================================================
The document open notification is sent from the client to the server to signal
newly opened text documents. The document's truth is now managed by the client
and the server must not try to read the document's truth using the document's
uri. Open in this sense means it is managed by the client. It doesn't necessarily
mean that its content is presented in an editor. An open notification must not
be sent more than once without a corresponding close notification send before.
This means open and close notification must be balanced and the max open count
is one.

The 'workspace/configuration' request is sent from the server to the client to fetch a certain
configuration setting.
This pull model replaces the old push model were the client signaled configuration change via an
event. If the server still needs to react to configuration changes (since the server caches the
result of `workspace/configuration` requests) the server should register for an empty configuration
change event and empty the cache if such an event is received.

A quick fix should be marked preferred if it properly addresses the underlying error.
A refactoring should be marked preferred if it is the most reasonable choice of actions to take.

* disabled: Marks that the code action cannot currently be applied.
Clients should follow the following guidelines regarding disabled code actions:
+ Disabled code actions are not shown in automatic [lightbulbs](https://code.visualstudio.com/docs/editor/editingevolved#_code-action)
code action menus.
+ Disabled actions are shown as faded out in the code action menu when the user requests a more specific type
of code action, such as refactorings.
+ If the user has a [keybinding](https://code.visualstudio.com/docs/editor/refactoring#_keybindings-for-code-actions)
that auto applies a code action and only disabled code actions are returned, the client should show the user an
error message with `reason` in the editor.@since 3.16.0
* edit: The workspace edit this code action performs.
* command: A command this code action executes. If a code action
provides an edit and a command, first the edit is
executed and then the command.
* data: A data entry field that is preserved on a code action between
a `textDocument/codeAction` and a `codeAction/resolve` request.

---------------------------------------
* label: The label of this completion item.
The label property is also by default the text that
is inserted when selecting this completion.
If label details are provided the label itself should
be an unqualified name of the completion item.
* label\_details: Additional details for the label
@since 3.17.0
* kind: The kind of this completion item. Based of the kind
an icon is chosen by the editor.
* tags: Tags for this completion item.
@since 3.15.0
* detail: A human-readable string with additional information
about this item, like type or symbol information.
* documentation: A human-readable string that represents a doc-comment.
* deprecated: Indicates if this item is deprecated.
@deprecated Use `tags` instead.
* preselect: Select this item when showing.
*Note* that only one completion item can be selected and that the
tool / client decides which item that is. The rule is that the *first*
item of those that match best is selected.
* sort\_text: A string that should be used when comparing this item
with other items. When `falsy` the {@link CompletionItem.label label}
is used.
* filter\_text: A string that should be used when filtering a set of
completion items. When `falsy` the {@link CompletionItem.label label}
is used.
* insert\_text: A string that should be inserted into a document when selecting
this completion. When `falsy` the {@link CompletionItem.label label}
is used.
The `insertText` is subject to interpretation by the client side.
Some tools might not take the string literally. For example
VS Code when code complete is requested in this example
`con<cursor position>` and a completion item with an `insertText` of
`console` is provided it will only insert `sole`. Therefore it is
recommended to use `textEdit` instead since it avoids additional client
side interpretation.
* insert\_text\_format: The format of the insert text. The format applies to both the
`insertText` property and the `newText` property of a provided
`textEdit`. If omitted defaults to `InsertTextFormat.PlainText`.
Please note that the insertTextFormat doesn't apply to
`additionalTextEdits`.
* insert\_text\_mode: How whitespace and indentation is handled during completion
item insertion. If not provided the clients default value depends on
the `textDocument.completion.insertTextMode` client capability.
@since 3.16.0
* text\_edit: An {@link TextEdit edit} which is applied to a document when selecting
this completion. When an edit is provided the value of
{@link CompletionItem.insertText insertText} is ignored.
Most editors support two different operations when accepting a completion
item. One is to insert a completion text and the other is to replace an
existing text with a completion text. Since this can usually not be
predetermined by a server it can report both ranges. Clients need to
signal support for `InsertReplaceEdits` via the
`textDocument.completion.insertReplaceSupport` client capability
property.
*Note 1:* The text edit's range as well as both ranges from an insert
replace edit must be a [single line] and they must contain the position
at which completion has been requested.
*Note 2:* If an `InsertReplaceEdit` is returned the edit's insert range
must be a prefix of the edit's replace range, that means it must be
contained and starting at the same position.
@since 3.16.0 additional type `InsertReplaceEdit`
* text\_edit\_text: The edit text used if the completion item is part of a CompletionList and
CompletionList defines an item default for the text edit range.
Clients will only honor this property if they opt into completion list
item defaults using the capability `completionList.itemDefaults`.
If not provided and a list's default range is provided the label
property is used as a text.
@since 3.17.0
* additional\_text\_edits: An optional array of additional {@link TextEdit text edits} that are applied when
selecting this completion. Edits must not overlap (including the same insert position)
with the main {@link CompletionItem.textEdit edit} nor with themselves.
Additional text edits should be used to change text unrelated to the current cursor position
(for example adding an import statement at the top of the file if the completion item will
insert an unqualified type).
* commit\_characters: An optional set of characters that when pressed while this completion is active will accept it first and
then type that character. *Note* that all commit characters should have `length=1` and that superfluous
characters will be ignored.
* command: An optional {@link Command command} that is executed *after* inserting this completion. *Note* that
additional modifications to the current document should be described with the
{@link CompletionItem.additionalTextEdits additionalTextEdits}-property.
* data: A data entry field that is preserved on a completion item between a
{@link CompletionRequest} and a {@link CompletionResolveRequest}.

* is\_incomplete: This list it not complete. Further typing results in recomputing this list.
Recomputed lists have all their items replaced (not appended) in the
incomplete completion sessions.
* item\_defaults: In many cases the items of an actual completion result share the same
value for properties like `commitCharacters` or the range of a text
edit. A completion list can therefore define item defaults which will
be used if a completion item itself doesn't specify the value.
If a completion list specifies a default value and a completion item
also specifies a corresponding value the one from the item is used.
Servers are only allowed to return default values if the client
signals support for this via the `completionList.itemDefaults`
capability.
@since 3.17.0
* items: The completion items.

* notebook\_document: The notebook document that did change. The version number points
to the version after all provided changes have been applied. If
only the text document content of a cell changes the notebook version
doesn't necessarily have to change.
* change: The actual changes to the notebook document.The changes describe single state changes to the notebook document.
So if there are two changes c1 (at array index 0) and c2 (at array
index 1) for a notebook in state S then c1 moves the notebook from
S to S' and c2 from S' to S''. So c1 is computed on the state S and
c2 is computed on the state S'.To mirror the content of a notebook using change events use the following approach:
+ start with the same initial content
+ apply the 'notebookDocument/didChange' notifications in the order you receive them.
+ apply the `NotebookChangeEvent`s in a single notification in the order
you receive them.

* markdown: Client capabilities specific to the client's markdown parser.
@since 3.16.0
* position\_encodings: The position encodings supported by the client. Client and server
have to agree on the same position encoding to ensure that offsets
(e.g. character position in a line) are interpreted the same on both
sides.
To keep the protocol backwards compatible the following applies: if
the value 'utf-16' is missing from the array of position encodings
servers can assume that the client supports UTF-16. UTF-16 is
therefore a mandatory encoding.
If omitted it defaults to ['utf-16'].
Implementation considerations: since the conversion from one encoding
into another requires the content of the file / line the conversion
is best done where the file is read which is usually on the server
side.

Is `null` if the process has not been started by another process.
If the parent process is not alive then the server should exit.
* client\_info: Information about the client
@since 3.15.0
* locale: The locale the client is currently showing the user interface
in. This must not necessarily be the locale of the operating
system.
Uses IETF language tags as the value's syntax
(See <https://en.wikipedia.org/wiki/IETF_language_tag>)
@since 3.16.0
* root\_path: The rootPath of the workspace. Is null
if no folder is open.
@deprecated in favour of rootUri.
* root\_uri: The rootUri of the workspace. Is null if no
folder is open. If both `rootPath` and `rootUri` are set
`rootUri` wins.
@deprecated in favour of workspaceFolders.
* capabilities: The capabilities provided by the client (editor or tool)
* initialization\_options: User provided initialization options.
* trace: The initial trace setting. If omitted trace is disabled ('off').
* workspace\_folders: The workspace folders configured in the client when the server starts.
This property is only available if the client supports workspace folders.
It can be `null` if the client supports workspace folders but none are
configured.

GenLSP.Structures.MarkupContent
(gen\_lsp v0.6.0)
==================================================================================================================================================================================================
A `MarkupContent` literal represents a string value which content is interpreted base on its
kind flag. Currently the protocol supports `plaintext` and `markdown` as markup kinds.
If the kind is `markdown` then the value can contain fenced code blocks like in GitHub issues.
See <https://help.github.com/articles/creating-and-highlighting-code-blocks/#syntax-highlighting>
Here is an example how such a string can be constructed using JavaScript / TypeScript:
```
let markdown: MarkdownContent = {
kind: MarkupKind.Markdown,
value: [
'# Header',
'Some text',
'```typescript',
'someCode();',
'```'
].join('
')
};
```
*Please Note* that clients might sanitize the return markdown. A client could decide to
remove HTML from the markdown to avoid script execution.

GenLSP.Structures.Position
(gen\_lsp v0.6.0)
=======================================================================================================================================================================================
Position in a text document expressed as zero-based line and character
offset. Prior to 3.17 the offsets were always based on a UTF-16 string
representation. So a string of the form `aπb` the character offset of the
character `a` is 0, the character offset of `π` is 1 and the character
offset of b is 3 since `π` is represented using two code units in UTF-16.
Since 3.17 clients and servers can agree on a different string encoding
representation (e.g. UTF-8). The client announces it's supported encoding
via the client capability [`general.positionEncodings`](#clientCapabilities).
The value is an array of position encodings the client supports, with
decreasing preference (e.g. the encoding at index `0` is the most preferred
one). To stay backwards compatible the only mandatory encoding is UTF-16
represented via the string `utf-16`. The server can pick one of the
encodings offered by the client and signals that encoding back to the
client via the initialize result's property
[`capabilities.positionEncoding`](#serverCapabilities). If the string value
`utf-16` is missing from the client's capability `general.positionEncodings`
servers can safely assume that the client supports UTF-16. If the server
omits the position encoding in its initialize result the encoding defaults
to the string value `utf-16`. Implementation considerations: since the
conversion from one encoding into another requires the content of the
file / line the conversion is best done where the file is read which is
usually on the server side.
Positions are line end character agnostic. So you can not specify a position
that denotes `|` or `|` where `|` represents the character offset.
@since 3.17.0 - support for negotiated position encoding.

* dynamic\_registration: Whether implementation supports dynamic registration. If this is set to `true`
the client supports the new `(TextDocumentRegistrationOptions & StaticRegistrationOptions)`
return value for the corresponding server capability as well.
* requests: Which requests the client supports and might send to the server
depending on the server's capability. Please note that clients might not
show semantic tokens or degrade some of the user experience if a range
or full request is advertised by the client but not provided by the
server. If for example the client capability `requests.full` and
`request.range` are both set to true but the server only provides a
range provider the client might not render a minimap correctly or might
even decide to not show any semantic tokens at all.
* token\_types: The token types that the client supports.
* token\_modifiers: The token modifiers that the client supports.
* formats: The token formats the clients supports.
* overlapping\_token\_support: Whether the client supports tokens that can overlap each other.
* multiline\_token\_support: Whether the client supports tokens that can span multiple lines.
* server\_cancel\_support: Whether the client allows the server to actively cancel a
semantic token request, e.g. supports returning
LSPErrorCodes.ServerCancelled. If a server does the client
needs to retrigger the request.
@since 3.17.0
* augments\_syntax\_tokens: Whether the client uses semantic tokens to augment existing
syntax tokens. If set to `true` client side created syntax
tokens and semantic tokens are both used for colorization. If
set to `false` the client only uses the returned semantic tokens
for colorization.
If the value is `undefined` then the client behavior is not
specified.

Whenever possible implementors should make an active decision about
the active signature and shouldn't rely on a default value.
In future version of the protocol this property might become
mandatory to better express this.

lies outside the range of `signatures[activeSignature].parameters`
defaults to 0 if the active signature has parameters. If
the active signature has no parameters it is ignored.

* trigger\_kind: Action that caused signature help to be triggered.
* trigger\_character: Character that caused signature help to be triggered.
This is undefined when `triggerKind !== SignatureHelpTriggerKind.TriggerCharacter`
* is\_retrigger: `true` if signature help was already showing when it was triggered.
Retriggers occurs when the signature help is already active and can be caused by actions such as
typing a trigger character, a cursor move, or document content changes.
* active\_signature\_help: The currently active `SignatureHelp`.
The `activeSignatureHelp` has its `SignatureHelp.activeSignature` field updated based on
the user navigating through available signatures.

* deprecated: Indicates if this symbol is deprecated.
@deprecated Use tags instead
* location: The location of this symbol. The location's range is used by a tool
to reveal the location in the editor. If the symbol is selected in the
tool the range's start information is used to position the cursor. So
the range usually spans more than the actual symbol's name and does
normally include things like visibility modifiers.
The range doesn't have to denote a node range in the sense of an abstract
syntax tree. It can therefore not be used to re-construct a hierarchy of
the symbols.
* name: The name of this symbol.
* kind: The kind of this symbol.
* tags: Tags for this symbol.

* container\_name: The name of the symbol containing this symbol. This information is for
user interface purposes (e.g. to render a qualifier in the user interface
if necessary). It can't be used to re-infer a hierarchy for the document
symbols.

GenLSP.Structures.TextDocumentEdit
(gen\_lsp v0.6.0)
=========================================================================================================================================================================================================
Describes textual changes on a text document. A TextDocumentEdit describes all changes
on a document version Si and after they are applied move the document to version Si+1.
So the creator of a TextDocumentEdit doesn't need to sort the array of edits or do any
kind of ordering. However the edits must be non overlapping.

* title: Mandatory title of the progress operation. Used to briefly inform about
the kind of operation being performed.
Examples: "Indexing" or "Linking dependencies".
* cancellable: Controls if a cancel button should show to allow the user to cancel the
long running operation. Clients that don't support cancellation are allowed
to ignore the setting.
* message: Optional, more detailed associated progress message. Contains
complementary information to the `title`.
Examples: "3/25 files", "project/src/module2", "node\_modules/some\_dep".
If unset, the previous progress message (if any) is still valid.
* percentage: Optional progress percentage to display (value 100 is considered 100%).
If not provided infinite progress is assumed and clients are allowed
to ignore the `percentage` value in subsequent in report notifications.
The value should be steadily rising. Clients are free to ignore values
that are not following this rule. The value range is [0, 100].

GenLSP.Structures.WorkspaceEdit
(gen\_lsp v0.6.0)
==================================================================================================================================================================================================
A workspace edit represents changes to many resources managed in the workspace. The edit
should either provide `changes` or `documentChanges`. If documentChanges are present
they are preferred over `changes` if the client can handle versioned document edits.
Since version 3.13.0 a workspace edit can contain resource operations as well. If resource
operations are present clients need to execute the operations in the order in which they
are provided. So a workspace edit for example can consist of the following two changes:
(1) a create file a.txt and (2) a text document edit which insert text into file a.txt.
An invalid sequence (e.g. (1) delete file a.txt and (2) insert text into file a.txt) will
cause failure of the operation. How the client recovers from the failure is described by
the client capability: `workspace.workspaceEdit.failureHandling`

* changes: Holds changes to existing resources.
* document\_changes: Depending on the client capability `workspace.workspaceEdit.resourceOperations` document changes
are either an array of `TextDocumentEdit`s to express changes to n different text documents
where each text document edit addresses a specific version of a text document. Or it can contain
above `TextDocumentEdit`s mixed with create, rename and delete file / folder operations.
Whether a client supports versioned document edits is expressed via
`workspace.workspaceEdit.documentChanges` client capability.
If a client neither supports `documentChanges` nor `workspace.workspaceEdit.resourceOperations` then
only plain `TextEdit`s using the `changes` property are supported.
* change\_annotations: A map of change annotations that can be referenced in `AnnotatedTextEdit`s or create, rename and
delete file / folder operations.
Whether clients honor this property depends on the client capability `workspace.changeAnnotationSupport`.

=================================================================================================================================================================================================
MarkedString can be used to render human readable text. It is either a markdown string
or a code-block that provides a language and a code snippet. The language identifier
is semantically equal to the optional language identifier in fenced code blocks in GitHub
issues. See <https://help.github.com/articles/creating-and-highlighting-code-blocks/#syntax-highlighting>
The pair of a language and a value is an equivalent to markdown:
```
${value}
```
Note that markdown strings will be sanitized - that means html will be escaped.
@deprecated use MarkupContent instead.

* `?` to match on one character in a path segment
* `**` to match any number of path segments, including none
* `{}` to group sub patterns into an OR expression. (e.g. `**β/*.{ts,js}` matches all TypeScript and JavaScript files)
* `[]` to declare a range of characters to match in a path segment (e.g., `example.[0-9]` to match on `example.0`, `example.1`, β¦)
* `[!...]` to negate a range of characters to match in a path segment (e.g., `example.[!0-9]` to match on `example.a`, `example.b`, but not `example.0`)
@sample A language filter that applies to typescript files on disk: `{ language: 'typescript', scheme: 'file' }`

Both public and signed urls will include the timestamp for cache
busting, and are retrieved the exact same way as using Waffle
directly.

# To receive a single rendition:
MyApp.Uploaders.AvatarUploader.url({user.avatar, user}, :thumb)

# To receive all renditions:
MyApp.Uploaders.AvatarUploader.urls({user.avatar, user})
#=> %{original: "https://.../original.png?v=1234", thumb: "https://.../thumb.png?v=1234"}
# To receive a signed url:

How to use `:id` in filepath

In order to use `:id` attribute within file's path, we should separate
creation stage on two steps:
* persist the resource
* upload the file
It needs to be done because `:id` not yet exist on creation stage.

Example
-----------------------------
To implement this we should define `storage_dir/2` inside uploader
```
def storage\_dir(\_version, {\_file, scope}) do
"uploads/avatar/#{scope.id}"
end
```
Then define two separate `changeset`s inside our resource
```
def changeset(user, attrs) do
user
|> cast(attrs, [:name])
|> validate\_required([:name])
end
def avatar\_changeset(user, attrs) do
user
|> cast\_attachments(attrs, [:avatar])
|> validate\_required([:avatar])
end
```
Finally, we can combine two stages into one action
```
Ecto.Multi.new()
|> Ecto.Multi.insert(:user, User.changeset(user, attrs))
|> Ecto.Multi.update(:user\_with\_avatar, &User.avatar\_changeset(&1.user, attrs))
|> Repo.transaction()
```
This can be used in a Phoenix app context like
```
defmodule Accounts do
# ...
def create\_user(attrs \\ %{}) do
Ecto.Multi.new()
|> Ecto.Multi.insert(:user, User.changeset(%User{}, attrs))
|> Ecto.Multi.update(:user\_with\_avatar, &User.avatar\_changeset(&1.user, attrs))
|> Repo.transaction()
|> case do
{:ok, %{user\_with\_avatar: user}} -> {:ok, user}
{:error, \_, changeset, \_} -> {:error, changeset}
end
def update\_user(%User{} = user, attrs) do
user
|> User.changeset(attrs)
|> User.avatar\_changeset(attrs)
|> Repo.update()
end
def change\_user(%User{} = user, attrs \\ %{}) do
user
|> User.changeset(attrs)
|> User.avatar\_changeset(attrs)
end
# ...
end
```

Noether
(noether v0.2.4)
=====================================
Noether aims to ease common data manipulation tasks by introducing simple algebraic functions and other utilities.
Functions and names are inspired (sometimes taken as-is) from Haskell.
The [`Noether.Maybe`](Noether.Maybe.html) module introduces operations on nullable values.
The [`Noether.Either`](Noether.Either.html) module introduces operations on `{:ok, _} | {:error, _}` values.
The [`Noether.List`](Noether.List.html) module introduces operations on lists.
The root module has a few simple functions one might find of use.

Noether.Either
(noether v0.2.4)
============================================
This module hosts several utility functions to work with `{:ok, _} | {:error, _}` values.
These type of values will be then called `Either`.

[Types](#types)
----------------
[either()](#t:either/0)
[fun0()](#t:fun0/0)
[fun1()](#t:fun1/0)
[Functions](#functions)
------------------------
[bind(a, f)](#bind/2)
Given an `{:ok, value}` and a function that returns an Either value, it applies the function on the `value`. It effectively "squashes" an `{:ok, {:ok, v}}` or `{:ok, {:error, _}}` to its most appropriate representation.
If an `{:error, _}` is given, it is returned as-is.
[cat\_either(a, f)](#cat_either/2)
Given a list of Either, the function is mapped only on the elements of type `{:ok, _}`. Other values will be discarded. A list of the results is returned outside of the tuple.
[choose(a, f, g)](#choose/3)
Given a value and two functions that return an Either, it applies the first one and returns the result if it matches `{:ok, _}`. Otherwise the second function is applied.
[either(a, f, g)](#either/3)
Given an Either and two functions, it applies the first or second one on the second value of the tuple, depending if the value is `{:ok, _}` or `{:error, _}` respectively.
[error?(a)](#error?/1)
It returns `true` only if the value given matches a `{:error, value}` type.
[flat\_map(either, f)](#flat_map/2)
Alias for [`bind/2`](#bind/2)
[flatten(either)](#flatten/1)
Alias for [`join/1`](#join/1).
[join(a)](#join/1)
Given an `{:ok, {:ok, value}}` it flattens the ok unwrapping the `value` and returning `{:ok, value}`.
If an `{:error, _}` is given, it is returned as-is.
[map(a, f)](#map/2)
Given an `{:ok, value}` and a function, it applies the function on the `value` returning `{:ok, f.(value)}`.
If an `{:error, _}` is given, it is returned as-is.
[map\_all(values, f)](#map_all/2)
Given a list of values and a function returning `{:ok, any}` or `{:error, any}`, it applies the function on every
`value` returning `{:ok, values}` if every `f.(v)` results in `{:ok, v}`; returning `{:error, _}` if `f.(v) results in an`.
[map\_error(a, f)](#map_error/2)
Given an Either and one function, it applies the function to the `{:error, _}` tuple.
[ok?(a)](#ok?/1)
It returns `true` only if the value given matches a `{:ok, value}` type.
[or\_else(a, f)](#or_else/2)
Given an Either and a function, it returns the value as-is when it's ok, or executes the function and returns its result.
[try(value, f)](#try/2)
Given a `value` and a function, it applies the function on the `value` returning `{:ok, f.(value)}`.
If the function throws an exception `e` then it is wrapped into an `{:error, e}`.
[unwrap(a, b \\ nil)](#unwrap/2)
It returns the value of an `{:ok, value}` only if such a tuple is given. If not, the default value (`nil` if not provided) is returned.
[wrap(a)](#wrap/1)
Given any value, it makes sure the result is an Either type.
[wrap\_err(a)](#wrap_err/1)
Given any value, it makes sure the result is an Either type.

EnviΜo Logo Β Β EnviΜo
================================================================================================================================
**EnviΜo** is basically a `GenEventΒ²`, the modern idiomatic pub-sub
implementation of event passing.
In a nutshell, **EnviΜo** is a set of handy tools to simplify dealing with Elixir
[`Registry`](https://hexdocs.pm/elixir/master/Registry.html). It includes
the instance of [`Registry`](https://hexdocs.pm/elixir/Registry.html) to be used out of the box, scaffolds for
producing *publishers* and *subscribers*.
It is built using βconvention over configurationβ approach, preserving the whole
low-level control over the registry entries.
Just add the application `:envio` into your list of *extra* applications
and the default `Envio.Registry` will be started and managed automagically.
```
def application do
[
mod: {MyApplication, []},
extra\_applications: ~w|envio ...|a
]
end
```
###
[creating-a-publisher](#creating-a-publisher)
Creating a publisher
To create a publisher just `use Envio.Publisher` in the module that should
publish messages to the subscribers. Once `use Envio.Publisher` is used,
`broadcast/2` function becomes available. If the optional `channel:`
argument is passed to `use Envio.Publisher`, this channel is considered
the default one and `broadcast/1` function appears to publish directly
to the default channel.
```
defmodule MyPub do
use Envio.Publisher, channel: :main
def publish(channel, what), do: broadcast(channel, what)
def publish(what), do: broadcast(what)
end
```
Another option that might be passed to `use Envio.Publisher` is `manager:`, that might be either `:registry` (default,) or `:phoenix_pub_sub` to use [`Phoenix.PubSub`](https://hexdocs.pm/phoenix_pubsub) for distributed message broadcasting.
###
[creating-a-subscriber](#creating-a-subscriber)
Creating a subscriber
#### βΆ [`:dispatch`](https://hexdocs.pm/elixir/master/Registry.html#module-using-as-a-dispatcher)
Simply register the handler anywhere in the code:
```
Envio.register(
{MySub, :on\_envio}, # the function of arity 2 must exist
dispatch: %Envio.Channel{source: MyPub, name: :main}
)
```
As `MyPub` publishes to the `:main` channel, `MySub.on_envio/2` will
be called with a message passed as parameter.
#### βΆ [`:pub_sub`](https://hexdocs.pm/elixir/master/Registry.html#module-using-as-a-pubsub)
Use [`Envio.Subscriber`](Envio.Subscriber.html) helper to scaffold the registry subscriber. Implement
`handle_envio/2` for custom message handling. The default implementation
collects last `10` messages in itβs state. This amount might be adjusted by
changing `:envio, :subscriber_queue_size` application environment setting.
The implementation below subscribes to `:main` channel provided by `MyPub`
publisher and prints out each subsequent incoming message to standard output.
```
defmodule PubSucker do
use Envio.Subscriber, channels: [{MyPub, :main}]
def handle\_envio(message, state) do
{:noreply, state} = super(message, state)
IO.inspect({message, state}, label: "Received")
{:noreply, state}
end
end
```
#### βΆ [`:phoenix_pub_sub`](https://hexdocs.pm/phoenix_pubsub)
Use `manager: :phoenix_pub_sub` for distributed message broadcasting. The implementation below subscribes to `"main"` channel in the distributed OTP environment and prints out each subsequent incoming message to standard output.
```
defmodule Pg2Sucker do
use Envio.Subscriber, channels: ["main"], manager: :phoenix\_pub\_sub
def handle\_envio(message, state) do
{:noreply, state} = super(message, state)
IO.inspect({message, state}, label: "Received")
{:noreply, state}
end
end
```
The publisher this subscriber might be listening to would look like
```
defmodule Pg2Spitter do
use Envio.Publisher, manager: :phoenix\_pub\_sub, channel: "main"
def spit(channel, what), do: broadcast(channel, what)
def spit(what), do: broadcast(what)
end
```

Envio.Publisher behaviour
(envio v0.10.2)
=============================================================================================================================================================
Publisher helper scaffold.
Simply `use Envio.Publisher` in the module that should publish messages.
The `broadcast/2` function becomes available. If the optional `channel:`
argument is passed to `use Envio.Publisher`, this channel is considered
the default one and `broadcast/1` function appears to publish directly
to the default channel.
The ready-to-copy-paste example of usage would be:
```
defmodule MyPub do
use Envio.Publisher, channel: :main
def publish(channel, what), do: broadcast(channel, what)
def publish(what), do: broadcast(what)
end
```
All the *subscribers* of the particular channel the message was published
to, will either receive a message (in the case of
[`:pub_sub`](https://hexdocs.pm/elixir/master/Registry.html#module-using-as-a-pubsub))
or called back with the function provided on subscription
([`:dispatch`](https://hexdocs.pm/elixir/master/Registry.html#module-using-as-a-dispatcher)).
Since `v0.8.0` `EnviΜo` supports [`Phoenix.PubSub`](https://hexdocs.pm/phoenix_pubsub) for distributed message broadcasting.
The publisher does not wrap [`:via`](https://hexdocs.pm/elixir/master/Registry.html#module-using-in-via)
functionality since it makes not much sense.
For how to subscribe, see [`Envio.Subscriber`](Envio.Subscriber.html).

To easy register the `pub_sub` consumer in `Envio.Registry`, one might
use this helper to scaffold the registering/unregistering code.
It turns the module into the [`GenServer`](https://hexdocs.pm/elixir/GenServer.html) and provides the handy wrapper
for the respective `handle_info/2`. One might override
`handle_envio` to implement custom handling.
The typical usage would be:
```
defmodule PubSubscriber do
use Envio.Subscriber, channels: [{PubPublisher, :foo}]
def handle\_envio(message, state) do
with {:noreply, state} <- super(message, state) do
IO.inspect({message, state}, label: "Received message")
{:noreply, state}
end
end
end
```
If channels are not specified as a parameter in call to `use Envio.Subscriber`,
this module might subscribe to any publisher later with `subscribe/1`:
```
PubSubscriber.subscribe(%Envio.Channel{source: PubPublisher, name: :foo})
```
For how to publish, see [`Envio.Publisher`](Envio.Publisher.html).

Overview
===========================================================================================================
srly is a native interface to serial devices for Erlang, known to work
on Mac OS X, FreeBSD and Linux.
The C component of srly simply provides a wrapper to the system serial
interface. Data structures used as arguments to the native C functions
(such as struct termios) are provided as Erlang binaries, allowing
low level control of the serial device.
[compiling](#compiling)
COMPILING
-----------------------------------
```
rebar3 compile
```
[usage](#usage)
USAGE
-----------------------
*serctl* is the interface to the native system C libraries and follows
the system C interface.
```
serctl:open(Path) -> {ok, FD} | {error, posix()}
Types Path = iodata() | {fd, FD}
FD = resource()
Open a serial device.
A serial device is a character device such as /dev/ttyUSB0.
A previously opened file descriptor can also be used. The fd
should be opened with the O\_NONBLOCK|O\_NOCTTY flags.
serctl:close(FD) -> ok | {error, posix()}
Types FD = resource()
Explicitly close a serial device.
The device is automatically closed if the process holding open
the serial device exits.
serctl:read(FD, Size) -> {ok, Data} | {error, posix()}
Types FD = resource()
Size = integer()
Data = binary()
Read from a serial device.
Size is an unsigned long.
serctl:readx(FD, Size) -> {ok, Data} | {error, posix()}
serctl:readx(FD, Size, Timeout) -> {ok, Data} | {error, posix()}
Types FD = resource()
Size = integer()
Data = binary()
Timeout = infinity | integer()
Read the specified number of bytes from a serial device. readx/2
will block forever.
readx/3 accepts a timeout value. The behaviour of readx/3 when
the timeout is reached is to throw away any buffered data and
return {error, eintr} to the caller, e.g., the caller will not
be returned the contents of a partial read. (The justification
for this behaviour: the caller has stated they require a fixed
number of bytes so the contents of a partial read represents
unspecified behaviour.)
serctl:write(FD, Data) -> ok | {ok, NBytes} | {error, posix()}
Types FD = resource()
Data = binary()
NBytes = long()
Write data to a serial device.
Partial writes return the number of bytes written.
serctl:ioctl(FD, Request, In) -> {ok, Out} | {error, posix()}
Types FD = resource()
Request = ulong()
In = binary()
Out = binary()
Perform operations controlling a serial device.
The In argument is a binary holding the input parameter to the
device request. The Out parameter will hold the result of the
request if the ioctl is in/out.
```
The low level interface follows the C library (see tcgetattr(3),
tcsetattr(3), cfsetispeed(3) and cfsetospeed(3) for details). For
convenience, atoms may be used in places where C has defined macros for
integers and Erlang records can be used as arguments instead of binaries.
To use Erlang records to represent the C struct termios (e.g., when
converting binaries using serctl:termios/1) include their definition:
```
-include("serctl.hrl").
serctl:tcgetattr(FD) -> {ok, Termios} | {error, posix()}
Types FD = resource()
Termios = binary()
Get the terminal attributes of a serial device.
Returns the contents of the system struct termios as a binary.
serctl:tcsetattr(FD, Action, Termios) -> ok | {error, posix() | unsupported}
Types FD = resource()
Action = integer() | Option | Options
Options = [Option]
Option = tcsanow | tcsadrain | tcsaflush | tcsasoft
Termios = binary() | #termios{}
Sets the terminal attributes of a serial device.
'tcsasoft' is a non-portable, BSD action. tcsetattr/3 will return
{error,unsupported} on other platforms.
Warning: the contents of Termios are passed directly to
tcsettr(3). If the system tcsettr(3) does not perform any
validation of the structure, it is possible the Erlang VM may
crash.
serctl:cfsetispeed(Termios, Speed) -> Termios1
Types Termios = binary() | #termios{}
Speed = integer() | atom()
Termios1 = binary()
Set the input speed of a serial device.
See the warning for tcsetattr/2.
Failure: badarg if Speed is an invalid atom.
serctl:cfsetospeed(Termios, Speed) -> Termios1
Types Termios = binary() | #termios{}
Speed = integer() | atom()
Termios1 = binary()
Set the input speed of the serial device.
See the warning for tcsetattr/2.
Failure: badarg if Speed is an invalid atom.
serctl:getfd(FD) -> integer()
Types FD = resource()
Returns the file descriptor associated with the NIF resource.
The file descriptor can be used with erlang:open\_port/2.
serctl:constant() -> Constants
serctl:constant(Attr) -> integer() | undefined
Types Constants = [{Attr, integer()}]
Attr = tiocm\_rts | tiocm\_dtr | tiocmset | tiocmget | tiocmbis

Map of atoms representing terminal attribute constants to
integers. Varies across platforms.
```
serctl has a higher level interface for manipulating the C data structures
that takes care of portability. The structures are represented as Erlang
records. These functions only retrieve or modify values within the termios
structure and do not have side effects when used with the record format
(when binaries are used as arguments, they are first converted to record
format based on a runtime platform check).
To modify the serial device, the attributes must be written out using
serctl:tcsetattr/3.
```
serctl:flow(Termios) -> true | false
serctl:flow(Termios, Bool) -> #termios{}
Types Termios = binary() | #termios{}
Bool = true | false
Get/set serial device flow control.
flow/1 indicates whether flow control is enabled in a serial
device's terminal attributes. flow/2 returns a termios structure
that can be used for setting a serial device's flow control.
serctl:mode(Mode) -> #termios{}
Types Mode = raw
Returns an Erlang termios record with attributes that can be
used to put the serial device into raw mode.
serctl:getflag(Termios, Flag, Opt) -> true | false
Types Termios = binary() | #termios{}
Flag = cflag | lflag | iflag | oflag
Opt = atom()
Returns whether a flag is enabled. Opt is one of the atoms
returned using serctl:constant/0.
serctl:setflag(Termios, Opt) -> #termios{}
Types Termios = #termios{}
Opt = [Param]
Param = {Flag, [Val]}
Flag = cflag | lflag | iflag | oflag
Val = {atom(), Bool}
Bool = true | false
Returns an Erlang termios record which can be used for setting
the attributes of a serial device. For example, to create
attributes that can be used to enable hardware flow control on
a serial device:
{ok, FD} = serctl:open("/dev/ttyUSB0"),
{ok, Termios} = serctl:tcgetattr(FD),
Termios1 = serctl:setflag(Termios, [{cflag, [{crtscts, true}]}]),
ok = serctl:tcsetattr(FD, tcsanow, Termios1).
serctl:ispeed(Termios) -> integer()
serctl:ispeed(Termios, Speed) -> #termios{} | binary()
serctl:ospeed(Termios) -> integer()
serctl:ospeed(Termios, Speed) -> #termios{} | binary()
Types Termios = #termios{}
Speed = integer() | atom()
ispeed/1 and ospeed/1 return the input and output speed of the
serial device. Note the speed returned is the constant defined
for the system and may differ between platforms.
ispeed/2 and ospeed/2 return an Erlang termios record that can be
used for setting the input and output speed of the serial device.
Failure: badarg if Speed is an invalid atom.
serctl:baud(Speed) -> integer()
Types Speed = 115200 | 19200 | 9600 | ...
Return the constant defined for the baud rate for the platform.
serctl:termios(Termios) -> #termios{} | binary()
Types Termios = #termios{} | binary()
Convert between a C struct termios and an Erlang record.
```

```
Read the specified number of bytes from a serial device
readx/2 will block forever.
readx/3 accepts a timeout value. The behaviour of readx/3 when the timeout is reached is to throw away any buffered data and return {error, eintr} to the caller, e.g., the caller will not be returned the contents of a partial read. (The justification for this behaviour: the caller has stated they require a fixed number of bytes so the contents of a partial read represents unspecified behaviour.)

run(application, opts \\ [])
============================
[View Source](https://github.com/ndreynolds/ratatouille/blob/master/lib/ratatouille.ex#L45 "View Source")
Starts an application under a supervised runtime, given a module implementing
the `Ratatouille.Application` behaviour. This call blocks until the
application is quit (or it crashes).
This is intended as a way to easily run simple apps and examples. For more
complex apps depending on other processes, it's recommended to define an OTP
application and start the [`Ratatouille.Runtime.Supervisor`](Ratatouille.Runtime.Supervisor.html) as a child of your
application supervisor.
###
Example
```
defmodule Counter do
@behaviour Ratatouille.App
import Ratatouille.View
def init(\_context), do: 0
def update(model, msg) do
case msg do
{:event, %{ch: ?+}} -> model + 1
{:event, %{ch: ?-}} -> model - 1
\_ -> model
end
end
def render(model) do
view do
label(content: "Counter is #{model} (+/-)")
end
end
end

Architecture
---------------
You may have recognized this pattern from [the Elm Architecture](https://guide.elm-lang.org/architecture/). That's because
[`Ratatouille.App`](#content) is just a close translation of this architecture to Elixir.
Because Elixir and Elm are both functional programming languages, the pattern
also works very well in Elixir. It helps to centralize state,
The architecture cleanly separates logic into the following three parts:
* **Model:** the state of your application
* **Update:** a way to update your state
* **View:** a way to view your state as a `%Ratatouille.Element{}` tree (think
HTML).
The behaviour callbacks map to these three parts:
* [`init/1`](#c:init/1) defines your initial model, using provided context if needed.
* [`update/2`](#c:update/2) handles a message and retuns a new model.
* [`render/1`](#c:render/1) receives a model and builds a view (an element tree) to view it.
See the documentation for each callback below for additional details.
Runtime
----------
As long as you implement the behaviour callbacks, Ratatouille can handle the
rest. It provides a runtime ([`Ratatouille.Runtime`](Ratatouille.Runtime.html)), which will handle
actually running your application. That means setting up the window, rendering
the view, subscribing to events and passing these on to the application's
`update/2` callback, and making sure the view is always re-rendered when the
application's model changes.
Fetching Data & Other Expensive Calls
----------------------------------------
A good rule of thumb for developing responsive UIs in any language is to never
block the UI thread. Here, we have a runtime process, but the same rule
applies.
In Ratatouille, your application should use [`Ratatouille.Runtime.Command`](Ratatouille.Runtime.Command.html) in
order to start asynchronous tasks and get the result in the `update/2`
callback once finished.

[render(model)](#c:render/1)
The `render/1` callback defines how to render the model as a view.
[subscribe(model)](#c:subscribe/1)
The optional `subscribe/1` callback defines a subscription for the application
given the initial model. Subscriptions are fulfilled via the `update/2`
callback.
[update(model, msg)](#c:update/2)
The `update/2` callback defines how to update the model in reaction to a
message (for example, an event or a tick).

```
init([context](#t:context/0)()) :: [model](#t:model/0)() | {[model](#t:model/0)(), Command.t()}
```
The `init/1` callback defines the initial model. This model can be defined
based on the runtime context. See the "Runtime Context" section under
[`Ratatouille.Runtime`](Ratatouille.Runtime.html) for details on what context is provided.

```
render([model](#t:model/0)()) :: Ratatouille.Renderer.Element.t()
```
The `render/1` callback defines how to render the model as a view.
It should return a `%Ratatouille.Element{}` with the `:view` tag. For example:
```
@impl true
def render(model) do
view do
label(content: "Hello, #{model.name}!")
end
end
```

(optional)
```
subscribe([model](#t:model/0)()) :: Subscription.t()
```
The optional `subscribe/1` callback defines a subscription for the application
given the initial model. Subscriptions are fulfilled via the `update/2`
callback.
For example, a subscription can be used to update the view every second (see
[`Ratatouille.Runtime.Subscription.interval/2`](Ratatouille.Runtime.Subscription.html#interval/2)):
```
@impl true
def subscribe(\_model) do
Subscription.interval(1\_000, :tick)
end
```
It's also possible to subscribe to multiple things via
[`Ratatouille.Runtime.Subscription.batch/1`](Ratatouille.Runtime.Subscription.html#batch/1). See
[`Ratatouille.Runtime.Subscription`](Ratatouille.Runtime.Subscription.html) for more details.

```
update([model](#t:model/0)(), [msg](#t:msg/0)()) :: [model](#t:model/0)() | {[model](#t:model/0)(), Command.t()}
```
The `update/2` callback defines how to update the model in reaction to a
message (for example, an event or a tick).
The following messages are currently passed to `update/2` by the runtime:
* `{:event, event}` - A keyboard or click event.
* `{:refresh, event}` - A resize event.
The callback should always return the model. It can be the same model or an
updated one. If the model changes, the runtime will know to re-render the
model and update the window.

A: top-left corner, e.g. (0, 0)
B: bottom-right corner, e.g. (10, 10)
```
For rendering purposes, the outermost box will typically have a top-left
corner (0, 0) and a bottom-right corner (x, y) where x is the number of rows
and y is the number of columns on the terminal.
This outermost box can then be subdivided as necessary to render different
elements of the view.

Ratatouille.Renderer.Canvas [View Source](https://github.com/ndreynolds/ratatouille/blob/master/lib/ratatouille/renderer/canvas.ex#L1 "View Source")
========================================================================================================================================================================
A canvas represents a terminal window, a subvision of it for rendering, and a
sparse mapping of positions to cells.
A `%Canvas{}` struct can be rendered to different output formats. This includes
the primary use-case of rendering to the termbox-managed window, but also
rendering to strings, which is useful for testing.

Ratatouille v0.5.1
Ratatouille.Runtime [View Source](https://github.com/ndreynolds/ratatouille/blob/master/lib/ratatouille/runtime.ex#L1 "View Source")
========================================================================================================================================================
A runtime for apps implementing the [`Ratatouille.App`](Ratatouille.App.html) behaviour. See
[`Ratatouille.App`](Ratatouille.App.html) for details on how to build apps.
Runtime Context
------------------
The runtime provides a map with additional context to the app's
[`Ratatouille.App.init/1`](Ratatouille.App.html#c:init/1) callback. This can be used, for example,
to get information about the terminal window. Currently, the following
attributes are provided via the map:
* `:window`: A map with `:height` and `:width` keys.
Shutdown Options
-------------------
When a quit event is received (by default, "q", "Q" or ctrl-c), the runtime
will carry out the configured shutdown strategy. The default strategy
(`:self`) just stops the runtime process itself. In certain cases, it may
be desirable to stop an OTP application or the system itself, so a few other
strategies are provided:
* `:supervisor` - Stops the runtime supervisor, which will terminate the
runtime process and other dependencies. The VM will still be running
afterwards unless stopped by other means.
* `{:application, name}` - Stops the named application. The VM will still be
running afterwards unless stopped by other means.
* `:system`: Gracefully stops the system (calls [`:init.stop/0`](http://www.erlang.org/doc/man/init.html#stop-0)). Gracefully
shutting down the VM ensures that all applications are stopped. There will
be some lag between sending the quit event and the OS process actually
exiting, as the VM needs about a second to stop this way. See the note below
if this is a problem.
If the `:system` option is too slow, it's possible to halt the system manually
with [`System.halt/0`](https://hexdocs.pm/elixir/System.html#halt/0). It's just important to ensure that the system is only
halted after the terminal was restored to its original state. Otherwise, there
may be rendering artifacts or issues with the cursor. The `:supervisor` option
can be used to properly halt the system by monitoring the runtime supervisor
and halting once it has exited. Alternatively, use the `:application` option
to stop an application that runs the runtime supervisor and halt in the
application's `stop/1` callback.

Starts the application runtime given a module defining a Ratatouille terminal
application.
Configuration
----------------
* `:app` (required) - The [`Ratatouille.App`](Ratatouille.App.html) to run.
* `:shutdown` - The strategy for stopping the terminal application when a quit
event is received.
* `:interval` - The runtime loop interval in milliseconds. The default
interval is 500 ms. A subscription can be fulfilled at most once every
interval, so this effectively configures the maximum subscription
resolution that's possible.
* `:quit_events` - Specifies the events that should quit the terminal
application. Given as a list of tuples conforming where each tuple conforms
to either `{:ch, ch}` or `{:key, key}`. If not specified, ctrl-c and q / Q
can be used to quit the application by default.

Returns a new command that can be returned in the [`Ratatouille.App.update/2`](Ratatouille.App.html#c:update/2)
or [`Ratatouille.App.init/1`](Ratatouille.App.html#c:init/1) callbacks.
Takes an anonymous function and a message. The message is used to send a
response back to your app along with the result. It can be any Erlang term, so
it's also possible to include identifiers (e.g., `{:finished, id}`).

Ratatouille v0.5.1
Ratatouille.Runtime.Subscription [View Source](https://github.com/ndreynolds/ratatouille/blob/master/lib/ratatouille/runtime/subscription.ex#L1 "View Source")
==================================================================================================================================================================================
Subscriptions provide a way for the app to be notified via
[`Ratatouille.App.update/2`](Ratatouille.App.html#c:update/2) when something interesting happens.
Subscriptions should be constructed via the functions below and not via the
struct directly, as this is internal and subject to change.
Currently, it's possible to subscribe to time intervals ([`interval/2`](#interval/2)) and to
create batch subscriptions (i.e., multiple time intervals). More subscription
types may be introduced later.
###
Accuracy of Time Intervals
Ratatouille's runtime loop, which handles subscriptions, runs on a interval
itself (by default, every 500 ms). This means that the runtime loop is the
minimum possible subscription interval. If a subscription's interval is more
frequent than the runtime loop interval, the runtime loop interval is the
subscription's effective interval.
There is also no guarantee that subscriptions will be processed on time, as
the runtime may be busy with other tasks (e.g., handling events or rendering).
With that said, if care is taken to keep expensive calls out of the runtime
loop, subscriptions should be processed very close to requested interval.

Ratatouille.View β Ratatouille v0.5.1
try { if(localStorage.getItem('night-mode') === 'true') document.body.className += ' night-mode'; } catch (e) { }
Ratatouille v0.5.1
Ratatouille.View [View Source](https://github.com/ndreynolds/ratatouille/blob/master/lib/ratatouille/view.ex#L1 "View Source")
==================================================================================================================================================
In Ratatouille, a view is simply a tree of elements. Each element in the tree
holds an attributes map and a list of zero or more child nodes. Visually, it
looks like something this:
```
%Element{
tag: :view,
attributes: %{},
children: [
%Element{
tag: :row,
attributes: %{},
children: [
%Element{tag: :column, attributes: %{size: 4}, children: []},
%Element{tag: :column, attributes: %{size: 4}, children: []},
%Element{tag: :column, attributes: %{size: 4}, children: []}
]
}
]
}
```
View DSL
-----------
Because it's a bit tedious to define views like that, Ratatouille provides a
DSL to define them without all the boilerplate.
Now we can turn the above into this:
```
view do
row do
column(size: 4)
column(size: 4)
column(size: 4)
end
end
```
While the syntax is more compact, the end result is exactly the same. This
expression produces the exact same `%Element{}` struct as defined above.
To use the DSL like this, we need to import all the functions:
```
import Ratatouille.View
```
Alternatively, import just the ones you need:
```
import Ratatouille.View, only: [view: 0, row: 0, column: 1]
```
###
Forms
All of the possible forms are enumerated below.
Element with tag `foo`:
```
foo()
```
Element with tag `foo` and attributes:
```
foo(size: 42)
```
Element with tag `foo` and children as list:
```
foo([
bar()
])
```
Element with tag `foo` and children as block:
```
foo do
bar()
end
```
Element with tag `foo`, attributes, and children as list:
```
foo(
[size: 42],
[bar()]
)
```
Element with tag `foo`, attributes, and children as block:
```
foo size: 42 do
bar()
end
```
###
Empty Elements
Similar to so-called "empty" HTML elements such as `<br />`, Ratatouille also
has elements for which passing content doesn't make sense. For example, the
leaf node `text` stores its content in its attributes and cannot have any
child elements of its own.
In such cases, the block and list forms are unsupported.
###
Validation
While some errors---such as passing children to empty elements---are prevented
by the DSL, it's still possible (for now, at least) to build
semantically-invalid element trees using the DSL. This means that the elements
are being used in a way that doesn't make sense to the renderer.
In order to prevent cryptic rendering errors, the renderer first validates the
element tree it's given and rejects the whole thing if the structure is
unsupported. It currently checks the following things:
* The top-level element passed to the renderer must have the `:view` tag.
* A parent element may only have child elements that have one of the
supported child tags for the parent element.
* An element must define all of its required attributes and may not define any
unknown attributes.
The last two rules are based on the element's specification in
`Ratatouille.Renderer.Element`.

[child\_spec(init\_arg)](#child_spec/1)
Returns a specification to start this module under a supervisor.
[close(pid \\ \_\_MODULE\_\_)](#close/1)
Closes the window by stopping the GenServer. Prior to this, termbox is
de-initialized so that the terminal is restored to its previous state.
[fetch(pid \\ \_\_MODULE\_\_, attr)](#fetch/2)
Fetches an attribute for the window. This is currently limited to the window
dimensions, which can be useful when laying out content.
[start\_link(opts \\ [])](#start_link/1)
Starts the gen\_server representing the window.
[update(pid \\ \_\_MODULE\_\_, view)](#update/2)

```
Fetches an attribute for the window. This is currently limited to the window
dimensions, which can be useful when laying out content.
Examples
-----------
```
iex> Window.fetch(:height)
{:ok, 124}
iex> Window.fetch(:width)

start_link([Keyword.t](https://hexdocs.pm/elixir/Keyword.html#t:t/0)()) :: [GenServer.on\_start](https://hexdocs.pm/elixir/GenServer.html#t:on_start/0)()
```
Starts the gen\_server representing the window.
The window is intended to be run as a singleton gen\_server process, as
initializing the underlying termbox library multiple times on the same TTY can
lead to undefined behavior.
Options
----------
* `:name` - Override the name passed to [`GenServer.start_link/3`](https://hexdocs.pm/elixir/GenServer.html#start_link/3). By
```
default, `name: Ratatouille.Window` is passed in order to
protect against accidental double initialization, but this
can be overridden by passing `nil` or an alternate value.
```
* `:input_mode` - Configure the input mode. See [`Ratatouille.Constants.input_mode/1`](Ratatouille.Constants.html#input_mode/1)
```
for possible values.
```
* `:output_mode` - Configure the output mode. See [`Ratatouille.Constants.output_mode/1`](Ratatouille.Constants.html#output_mode/1)
```
for possible values.

###
Usage
```
$ mix format
```
(Formats both Elixir and Surface code.)
Mix Task Usage (Elixir 1.12 and earlier)
-------------------------------------------
###
Configuration
Add `surface_inputs` to `.formatter.exs` with patterns for all Surface files:
```
# .formatter.exs
[
...,
# match all .sface files and all .ex files with ~F sigils
surface\_inputs: ["lib/\*\*/\*.{ex,sface}", ...]
]
```
If your project does not use `sface` files, you can omit `:surface_inputs` and
specify file patterns in the standard `:inputs` field instead. ([`mix surface.format`](Mix.Tasks.Surface.Format.html) will fall back to `:inputs`.) But be warned that including
`.sface` files in `:inputs` causes [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) to crash in Elixir 1.12 and
earlier.
For documentation of other `.formatter.exs` options, see [`mix surface.format`](Mix.Tasks.Surface.Format.html).
###
Usage
```
$ mix surface.format
```
Formatting rules
-------------------
The formatter mostly follows these rules:
* Only formats code inside of `~F"""` blocks and `.sface` files.
* Child nodes are typically indented 2 spaces in from their parent.
* Interpolated Elixir code (inside `{ }` brackets) is formatted by the
[official Elixir formatter](https://hexdocs.pm/elixir/Code.html#format_string!/2).
* HTML attributes are put on separate lines if the line is too long.
* Retains "lack of whitespace" such as `<p>No whitespace between text and tags</p>`.
* Collapses extra newlines down to at most one blank line.
See [`Surface.Formatter.format_string!/2`](Surface.Formatter.html#format_string!/2) for further documentation.
Example at a glance
----------------------
Out of the box, Surface code that looks like this:
```
<RootComponent with_many_attributes={ true } causing_this_line_to_wrap={ true} because_it_is_too_long={ "yes, this line is long enough to wrap" }>
<!-- HTML public comment (hits the browser) -->
{!-- Surface private comment (does not hit the browser) --}
<div :if={ @show_div }
class="container">
<p> Text inside paragraph </p>
<span>Text touching parent tags</span>
</div>
<Child items={[%{name: "Option 1", key: 1}, %{name: "Option 2", key: 2}, %{name: "Option 3", key: 3}, %{name: "Option 4", key: 4}]}>
Default slot contents
</Child>
</RootComponent>
```
will be formatted like this:
```
<RootComponent
with_many_attributes
causing_this_line_to_wrap
because_it_is_too_long="yes, this line is long enough to wrap"
>
<!-- HTML public comment (hits the browser) -->
{!-- Surface private comment (does not hit the browser) --}
<div :if={@show_div} class="container">
<p>
Text inside paragraph
</p>
<span>Text touching parent tags</span>
</div>
<Child items={[
%{name: "Option 1", key: 1},
%{name: "Option 2", key: 2},
%{name: "Option 3", key: 3},
%{name: "Option 4", key: 4}
]}>
Default slot contents
</Child>
</RootComponent>

```
Formats the given Surface code string. (Typically the contents of an `~F`
sigil or `.sface` file.)
In short:
* HTML/Surface elements are indented to the right of their parents.
* Attributes are split on multiple lines if the line is too long; otherwise on the same line.
* Elixir code snippets (inside `{ }`) are ran through the Elixir code formatter.
* Lack of whitespace is preserved, so that intended behaviors are not removed.
(For example, `<span>Foo bar baz</span>` will not have newlines or spaces added.)
Below the **Options** section is a non-exhaustive list of behaviors of the formatter.
Options
=======
* `:line_length` - the line length to aim for when formatting
the document. Defaults to 98. As with the Elixir formatter,
this value is used as reference but is not always enforced
depending on the context.
Indentation
===========
The formatter ensures that children are indented one tab (two spaces) in from
their parent.
Whitespace
==========
Whitespace that exists
-------------------------
As in regular HTML, any string of continuous whitespace is considered
equivalent to any other string of continuous whitespace. There are four
exceptions:
1. Macro components (with names starting with `#`, such as `<#Markdown>`)
2. `<pre>` tags
3. `<code>` tags
4. `<script>` tags
The contents of those tags are considered whitespace-sensitive, and developers
should sanity check after running the formatter.
Whitespace that doesn't exist (Lack of whitespace)
-----------------------------------------------------
As is sometimes the case in HTML, *lack* of whitespace is considered
significant. Instead of attempting to determine which contexts matter, the
formatter consistently retains lack of whitespace. This means that the
following
```
<div><p>Hello</p></div>
```
will not be changed. However, the following
```
<div> <p> Hello </p> </div>
```
will be formatted as
```
<div>
<p>
Hello
</p>
</div>
```
because of the whitespace on either side of each tag.
To be clear, this example
```
<div> <p>Hello</p> </div>
```
will be formatted as
```
<div>
<p>Hello</p>
</div>
```
because of the lack of whitespace in between the opening and closing `<p>` tags
and their child content.
Splitting children onto separate lines
-----------------------------------------
In certain scenarios, the formatter will move nodes to their own line:
(Below, "element" means an HTML element or a Surface component.)
1. If an element contains other elements as children, it will be surrounded by newlines.
2. If there is a space after an opening tag or before a closing tag, it is converted to a newline.
3. If a closing tag is put on its own line, the formatter ensures there's a newline before the next sibling node.
Since SurfaceFormatter doesn't know if a component represents an inline or block element,
it does not currently make distinctions between elements that should or should not be
moved onto their own lines, other than the above rules.
This allows inline elements to be placed among text without splitting them onto their own lines:
```
The <b>Dialog</b> is a stateless component. All event handlers
had to be defined in the parent <b>LiveView</b>.
```
Newline characters
---------------------
The formatter will not add extra newlines unprompted beyond moving nodes onto
their own line. However, if the input code has extra newlines, the formatter
will retain them but will collapse more than one extra newline into a single
one.
This means that
```
<p>Hello</p>
<p>Goodbye</p>
```
will be formatted as
```
<p>Hello</p>
<p>Goodbye</p>
```
HTML attributes and component props
===================================
HTML attributes such as `class` in `<p class="container">` and component
props such as `name` in `<Person name="Samantha">` are formatted to make use
of Surface features.
Inline literals
------------------
String literals are placed after the `=` without any interpolation brackets (`{ }`). This means that
```
<Component foo={"hello"} />
```
will be formatted as
```
<Component foo="hello" />
```
Also, `true` boolean literals are formatted using the Surface shorthand
whereby you can simply write the name of the attribute and it is passed in as
`true`. For example,
```
<Component secure={true} />
```
and
```
<Component secure=true />
```
will both be formatted as
```
<Component secure />
```
Interpolation (`{ }` brackets)
---------------------------------
Attributes that interpolate Elixir code with `{ }` brackets are ran through
the Elixir code formatter.
This means that:
* `<Foo num={123456} />` becomes `<Foo num={123_456} />`
* `list={[1,2,3]}` becomes `list={[1, 2, 3]}`
* `things={%{ one: "1", two: "2"}}` becomes `things={%{one: "1", two: "2"}}`
Sometimes the Elixir code formatter will add line breaks in the formatted
expression. In that case, SurfaceFormatter will ensure indentation lines up. If
there is a single attribute, it will keep the attribute on the same line as the
tag name, for example:
```
<Component list={[
{"foo", foo},
{"bar", bar}
]} />
```
However, if there are multiple attributes it will put them on separate lines:
```
<Child
list={[
{"foo", foo},
{"bar", bar}
]}
int={123}
/>
```
Whitespace in string attributes
----------------------------------
###
Code semantics must be maintained
It's critical that a code formatter never change the semantics of the code
it modifies. In other words, the behavior of a program should never change
due to a code formatter.
The **Whitespace** section above outlines how `SurfaceFormatter` preserves
code semantics by refusing to modify contents of `<script>`, `<code>` and
`<pre>` tags as well as macro components. And for the same reason, the
formatter does not introduce whitespace between HTML tags when there is none.
###
Code semantics in string attributes
This principle is also relevant to string attributes, such as:
```
<MyComponent string_prop=" string with whitespace " />
```
`SurfaceFormatter` cannot reliably guess whether application behavior will be
changed by formatting the contents of a string. For example, consider a
component with the following interface:
```
<List items="
apples (fuji)
oranges (navel)
bell peppers (green)
" />
```
The component internally splits on newline characters and outputs the following HTML:
```
<ul>
<li>apples (fuji)</li>
<li>oranges (navel)</li>
<li>bell peppers (green)</li>
</ul>
```
If `SurfaceFormatter` assumes it is safe to modify whitespace in string
attributes, then the Surface code would likely change to this:
```
<List items="apples (fuji) oranges (navel) bell peppers (green)" />
```
Which would output the following HTML:
```
<ul>
<li>apples (fuji) oranges (navel) bell peppers (green)</li>
</ul>
```
Notice that the behavior of the application would have changed simply by
running the formatter. It is for this reason that `SurfaceFormatter`
always retains precisely the same whitespace in attribute strings,
including both space and newline characters.
Wrapping attributes on separate lines
----------------------------------------
In the **Interpolation (`{ }` brackets)** section we noted that attributes
will each be put on their own line if there is more than one attribute and at
least one contains a newline after being formatted by the Elixir code
formatter.
There is another scenario where attributes will each be given their own line:
**any time the opening tag would exceed `line_length` if put on one line**.
This value is provided in `.formatter.exs` and defaults to 98.
The formatter indents attributes one tab in from the start of the opening tag
for readability:
```
<div
class="very long class value that causes this to exceed the established line length"
aria-role="button"
>
```
If you desire to have a separate line length for [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) and [`mix surface.format`](Mix.Tasks.Surface.Format.html),
provide `surface_line_length` in `.formatter.exs` and it will be given precedence
when running [`mix surface.format`](Mix.Tasks.Surface.Format.html). For example:
```
# .formatter.exs
[
surface\_line\_length: 120,
import\_deps: [...],
# ...
]
```
Developer Responsibility
========================
As with all changes (for both [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) and [`mix surface.format`](Mix.Tasks.Surface.Format.html)) it's
recommended that developers don't blindly run the formatter on an entire
codebase and commit, but instead sanity check each file to ensure the results
are desired.

Surface.Formatter.Phase behaviour (SurfaceFormatter v0.7.5)
[View Source](https://github.com/surface-ui/surface_formatter/blob/v0.7.5/lib/surface/formatter/phase.ex#L1 "View Source")
=======================================================================================================================================================================================
A phase implementing a single "rule" for formatting code. These work as middleware
between `Surface.Compiler.Parser.parse` and `Surface.Formatter.Render.node/2`
to modify node lists before they are rendered.
Some phases rely on other phases; `@moduledoc`s should make this explicit.
For reference, the formatter operates by running these phases in the following order:
* [`Surface.Formatter.Phases.TagWhitespace`](Surface.Formatter.Phases.TagWhitespace.html)
* [`Surface.Formatter.Phases.Newlines`](Surface.Formatter.Phases.Newlines.html)
* [`Surface.Formatter.Phases.SpacesToNewlines`](Surface.Formatter.Phases.SpacesToNewlines.html)

=============================================================================================================================================================================================
Adds indentation nodes (`:indent` and `:indent_one_less`) where appropriate.
`Surface.Formatter.Render.node/2` is responsible for adding the appropriate
level of indentation. It keeps track of the indentation level based on how
"nested" a node is. While running Formatter Phases, it's not necessary to
keep track of that detail.
`:indent_one_less` exists to notate the indentation that should occur before
a closing tag, which is one less than its children.
Relies on `Newlines` phase, which collapses :newline nodes to at most 2 in a row.

Surface.Formatter.Plugin (SurfaceFormatter v0.7.5)
[View Source](https://github.com/surface-ui/surface_formatter/blob/v0.7.5/lib/surface/formatter/plugin.ex#L1 "View Source")
===============================================================================================================================================================================
An [Elixir formatter
plugin](https://hexdocs.pm/mix/1.13.0-rc.1/Mix.Tasks.Format.html#module-plugins)
for Surface code.
Elixir 1.13 introduced formatter plugins, allowing the Surface formatter to
run during [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) instead of requiring developers to run [`mix surface.format`](Mix.Tasks.Surface.Format.html) separately.
To format Surface code using Elixir 1.12 or earlier, use [`mix surface.format`](Mix.Tasks.Surface.Format.html).
###
`.formatter.exs` setup
Add to `:plugins` in `.formatter.exs` in order to format `~F` sigils and
`.sface` files when running [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html).
Only works on files matching patterns in `:inputs`, so add patterns for
all Surface files to ensure they're formatted.
```
# in .formatter.exs
[
...,
plugins: [Surface.Formatter.Plugin]
# add patterns matching all .sface files and all .ex files with ~F sigils
inputs: ["\*.{ex,exs}", "{config,lib,test}/\*\*/\*.{ex,exs,sface}"],
# THE FOLLOWING ARE OPTIONAL:
# set desired line length for both Elixir's code formatter and this one
# (only affects opening tags in Surface)
line\_length: 80,
# or, set line length only for Surface code (overrides `line\_length`)
surface\_line\_length: 84
]
```
###
Options
In `.formatter.exs`, the following options can be provided:
* `:line_length` - Maximum line length of an opening tag before
SurfaceFormatter attempts to wrap it onto multiple lines. This option is
used by [`Code.format_string!/2`](https://hexdocs.pm/elixir/Code.html#format_string!/2) and [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) and defaults to 98.
* `:surface_line_length` - Overrides `:line_length`; useful for setting
separate desired line length for Surface code and non-Surface Elixir code.

**To format Surface code using Elixir 1.13 or later, use
[`Surface.Formatter.Plugin`](Surface.Formatter.Plugin.html).**
Formats Surface `~F` sigils and `.sface` files in the given files and patterns.
```
$ mix surface.format "lib/**/*.{ex,exs}" "test/**/*.{ex,exs}"
$ cat path/to/file.ex | mix surface.format -
```
Takes the same options as [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) except for `--check-equivalent`.
Formatting options
---------------------
Like [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html), the Surface formatter reads a `.formatter.exs` file in the
current directory for formatter configuration. The Surface formatter accepts
the same options as [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html). Read more about the expected format of
`.formatter.exs` and the shared configuration options
[documented here](https://hexdocs.pm/mix/master/Mix.Tasks.Format.html#module-formatting-options).
The Surface formatter also takes the following two additional options
specified in `.formatter.exs`:
* `:surface_line_length` overrides `:line_length` only for [`mix surface.format`](#content)
(`:line_length` is used otherwise, or defaults to 98)
* `:surface_inputs` overrides `:inputs` only for [`mix surface.format`](#content)
(`:inputs` is used otherwise)
Task-specific options
------------------------
The Surface formatter accepts the same task-specific options as [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html).
[Read documentation for the options documented here.](https://hexdocs.pm/mix/master/Mix.Tasks.Format.html#module-task-specific-options).
For quick reference, here are some examples of using these options:
```
$ mix surface.format --check-formatted
** (Mix) mix surface.format failed due to --check-formatted.
The following files are not formatted:
* path/to/component.ex
* path/to/file.sface
```
```
$ mix surface.format --dry-run
```
```
$ mix surface.format --dot-formatter path/to/.formatter.exs
```
You can also use the same syntax as [`mix format`](https://hexdocs.pm/mix/Mix.Tasks.Format.html) for specifying which files to
format:
```
$ mix surface.format path/to/file.ex "lib/**/*.{ex,exs}" "test/**/*.{ex,exs}"
```

MEEx
==================
MEx stands for Embedded Elixir. It allows you to embed
Elixir code inside a string in a robust way.
```
iex> MEEx.eval_string "foo {%= bar %}", [bar: "baz"]
"foo baz"
```
API
------
This module provides 3 main APIs for you to use:
1. Evaluate a string (`eval_string`) or a file (`eval_file`)
directly. This is the simplest API to use but also the
slowest, since the code is evaluated and not compiled before.
2. Define a function from a string (`function_from_string`)
or a file (`function_from_file`). This allows you to embed
the template as a function inside a module which will then
be compiled. This is the preferred API if you have access
to the template at compilation time.
3. Compile a string (`compile_string`) or a file (`compile_file`)
into Elixir syntax tree. This is the API used by both functions
above and is available to you if you want to provide your own
ways of handling the compiled template.
Options
----------
All functions in this module accept MEx-related options.
They are:
* `:line` - the line to be used as the template start. Defaults to 1.
* `:file` - the file to be used in the template. Defaults to the given
file the template is read from or to βnofileβ when compiling from a string.
* `:engine` - the MEx engine to be used for compilation.
* `:trim` - trims whitespace left/right of quotation tags
Engine
---------
MEx has the concept of engines which allows you to modify or
transform the code extracted from the given string or file.
By default, `MEx` uses the [`MEEx.SmartEngine`](MEEx.SmartEngine.html) that provides some
conveniences on top of the simple [`MEEx.Engine`](MEEx.Engine.html).
### Tags
[`MEEx.SmartEngine`](MEEx.SmartEngine.html) supports the following tags:
```
{% Elixir expression - inline with output %}
{%= Elixir expression - replace with result %}
{%% MEx quotation - returns the contents inside %}
{%# Comments - they are discarded from source %}
```
All expressions that output something to the template
**must** use the equals sign (`=`). Since everything in
Elixir is an expression, there are no exceptions for this rule.
For example, while some template languages would special-case
`if/2` clauses, they are treated the same in MEx and
also require `=` in order to have their result printed:
```
{%= if true do %}
It is obviously true
{% else %}
This will never appear
{% end %}
```
Notice that different engines may have different rules
for each tag. Other tags may be added in future versions.
### Macros
[`MEEx.SmartEngine`](MEEx.SmartEngine.html) also adds some macros to your template.
An example is the `@` macro which allows easy data access
in a template:
```
iex> MEEx.eval_string "{%= @foo %}", assigns: [foo: 1]
"1"
```
In other words, `{%= @foo %}` translates to:
```
{%= {:ok, v} = Access.fetch(assigns, :foo); v %}
```
The `assigns` extension is useful when the number of variables
required by the template is not specified at compilation time.

MEEx.Engine
behaviour
======================================
Basic MEx engine that ships with Elixir.
An engine needs to implement four functions:
* `init(opts)` - returns the initial buffer
* `handle_body(quoted)` - receives the final built quoted
expression, should do final post-processing and return a
quoted expression.
* `handle_text(buffer, text)` - it receives the buffer,
the text and must return a new quoted expression.
* `handle_expr(buffer, marker, expr)` - it receives the buffer,
the marker, the expr and must return a new quoted expression.
The marker is what follows exactly after `{%`. For example,
`{% foo %}` has an empty marker, but `{%= foo %}` has `"="`
as marker. The allowed markers so far are: `""` and `"="`.
Read [`handle_expr/3`](#handle_expr/3) below for more information about the markers
implemented by default by this engine.
[`MEEx.Engine`](MEEx.Engine.html#content) can be used directly if one desires to use the
default implementations for the functions above.

meex v1.4.1
MEEx.SmartEngine
==============================
The default engine used by MEEx.
It includes assigns (like `@foo`) and possibly other
conveniences in the future.
Examples
-----------
```
iex> MEEx.eval_string("{%= @foo %}", assigns: [foo: 1])
"1"
```
In the example above, we can access the value `foo` under
the binding `assigns` using `@foo`. This is useful because
a template, after being compiled, can receive different
assigns and would not require recompilation for each
variable set.
Assigns can also be used when compiled to a function:
```
# sample.mex
{%= @a + @b %}
# sample.ex
defmodule Sample do
require MEx
MEEx.function_from_file :def, :sample, "sample.mex", [:assigns]
end
# iex
Sample.sample(a: 1, b: 2) #=> "3"
```

WaitForIt [View Source](https://github.com/jvoegele/wait_for_it/blob/master/lib/wait_for_it.ex#L1 "View Source")
======================================================================================================================================
WaitForIt provides macros for various ways to wait for things to happen.
Since most Elixir systems are highly concurrent there must be a way to coordinate and synchronize
the processes in the system. While the language provides features (such as [`Process.sleep/1`](https://hexdocs.pm/elixir/Process.html#sleep/1) and
`receive`/`after`) that can be used to implement such synchronization, they are inconvenient to
use for this purpose. [`WaitForIt`](#content) builds on top of these language features to provide convenient
and easy-to-use facilities for synchronizing concurrent activities. While this is likely most
useful for test code in which tests must wait for concurrent or asynchronous activities to
complete, it is also useful in any scenario where concurrent processes must coordinate their
activity. Examples include asynchronous event handling, producer-consumer processes, and
time-based activity.
There are three distinct forms of waiting provided:
1. The `wait` macro waits until a given expression evaluates to a truthy value.
2. The `case_wait` macro waits until a given expression evaluates to a value that
matches any one of the given case clauses (looks like an Elixir `case` expression).
3. The `cond_wait` macro waits until any one of the given expressions evaluates to a truthy
value (looks like an Elixir `cond` expression).
All three forms accept the same set of options to control their behavior:
* `:timeout` - the amount of time to wait (in milliseconds) before giving up
* `:frequency` - the polling frequency (in milliseconds) at which to re-evaluate conditions
* `:signal` - disable polling and use a condition variable of the given name instead
* `:pre_wait` - wait for the given number of milliseconds before evaluating conditions for the first time
The `:signal` option warrants further explanation. By default, all three forms of waiting use
polling to periodically re-evaluate conditions to determine if waiting should continue. The
frequency of polling is controlled by the `:frequency` option. However, if the `:signal` option
is given it disables polling altogether. Instead of periodically re-evaluating conditions at a
particular frequency, a *condition variable* is used to signal when conditions should be
re-evaluated. It is expected that the `signal` macro will be used to unblock the waiting code
in order to re-evaluate conditions. For example, imagine a typical producer-consumer problem in
which a consumer process waits for items to appear in some buffer while a separate producer
process occasionally place items in the buffer. In this scenario, the consumer process might use
the `wait` macro with the `:signal` option to wait until there are some items in the buffer and
the producer process would use the `signal` macro to tell the consumer that it might be time for
it to check the buffer again.
```
# CONSUMER
# assume the existence of a `buffer\_size` function
WaitForIt.wait buffer\_size() >= 4, signal: :wait\_for\_buffer
```
```
# PRODUCER
# put some things in buffer, then:
WaitForIt.signal(:wait\_for\_buffer)
```
Notice that the same condition variable name `:wait_for_buffer` is used in both cases. It is
important to note that when using condition variables for signaling like this, both the `wait`
invocation and the `signal` invocation should be in the same Elixir module. This is because
[`WaitForIt`](#content) uses the calling module as a namespace for condition variable names to prevent
accidental name collisions with other registered processes in the application. Also note that
just because a condition variable has been signalled does not necessarily mean that any waiters
on that condition variable can stop waiting. Rather, a signal indicates that waiters should
re-evaluate their waiting conditions to determine if they should continue to wait or not.

==========================================
[View Source](https://github.com/jvoegele/wait_for_it/blob/master/lib/wait_for_it.ex#L181 "View Source")
(macro)
Wait until the given `expression` matches one of the case clauses in the given block.
Returns the value of the matching clause, the value of the optional `else` clause,
or a tuple of the form `{:timeout, timeout_milliseconds}`.
The `do` block passed to this macro must be a series of case clauses exactly like a built-in
Elixir `case` expression. Just like a `case` expression, the clauses will attempt to be matched
from top to bottom and the first one that matches will provide the resulting value of the
expression. The difference with `case_wait` is that if none of the clauses initially matches it
will wait and periodically re-evaluate the clauses until one of them does match or a timeout
occurs.
An optional `else` clause may also be used to provide the value in case of a timeout. If an
`else` clause is provided and a timeout occurs, then the `else` clause will be evaluated and
the resulting value of the `else` clause becomes the value of the `case_wait` expression. If no
`else` clause is provided and a timeout occurs, then the value of the `case_wait` expression is a
tuple of the form `{:timeout, timeout_milliseconds}`.
The optional `else` clause may also take the form of match clauses, such as those in a case
expression. In this form, the `else` clause can match on the final value of the expression that
was evaluated before the timeout occurred. See the examples below for an example of this.
Options
----------
See the WaitForIt module documentation for further discussion of these options.
* `:timeout` - the amount of time to wait (in milliseconds) before giving up
* `:frequency` - the polling frequency (in milliseconds) at which to re-evaluate conditions
* `:signal` - disable polling and use a condition variable of the given name instead
* `:pre_wait` - wait for the given number of milliseconds before evaluating conditions for the first time
Examples
-----------
Wait until queue has at least 5 messages, then return them:
```
WaitForIt.case\_wait Queue.get\_messages(queue), timeout: 30\_000, frequency: 100 do
messages when length(messages) > 4 -> messages
else
# If after 30 seconds we still don't have 5 messages, just return the messages we do have.
messages -> messages
end
```
A thermostat that keeps temperature in a small range:
```
def thermostat(desired\_temperature) do
WaitForIt.case\_wait get\_current\_temperature() do
temp when temp > desired\_temperature + 2 ->
turn\_on\_air\_conditioning()
temp when temp < desired\_temperature - 2 ->
turn\_on\_heat()
end
thermostat(desired\_temperature)
end
```
Ring the church bells every 15 minutes:
```
def church\_bell\_chimes do
count = WaitForIt.case\_wait Time.utc\_now.minute, frequency: 60\_000, timeout: 60\_000 \* 60 do
15 -> 1
30 -> 2
45 -> 3
0 -> 4
end
IO.puts(String.duplicate(" ding ding ding dong ", count))
church\_bell\_chimes()
end
```
[Link to this macro](#cond_wait/2 "Link to this macro")
cond\_wait(opts \\ [], blocks)
==============================
[View Source](https://github.com/jvoegele/wait_for_it/blob/master/lib/wait_for_it.ex#L247 "View Source")
(macro)
Wait until one of the expressions in the given block evaluates to a truthy value.
Returns the value corresponding with the matching expression, the value of the optional `else`
clause, or a tuple of the form `{:timeout, timeout_milliseconds}`.
The `do` block passed to this macro must be a series of expressions exactly like a built-in
Elixir `cond` expression. Just like a `cond` expression, the embedded expresions will be
evaluated from top to bottom and the first one that is truthy will provide the resulting value of
the expression. The difference with `cond_wait` is that if none of the expressions is initially
truthy it will wait and periodically re-evaluate them until one of them becomes truthy or a
timeout occurs.
An optional `else` clause may also be used to provide the value in case of a timeout. If an
`else` clause is provided and a timeout occurs, then the `else` clause will be evaluated and
the resulting value of the `else` clause becomes the value of the `cond_wait` expression. If no
`else` clause is provided and a timeout occurs, then the value of the `cond_wait` expression is a
tuple of the form `{:timeout, timeout_milliseconds}`.
Options
----------
See the WaitForIt module documentation for further discussion of these options.
* `:timeout` - the amount of time to wait (in milliseconds) before giving up
* `:frequency` - the polling frequency (in milliseconds) at which to re-evaluate conditions
* `:signal` - disable polling and use a condition variable of the given name instead
* `:pre_wait` - wait for the given number of milliseconds before evaluating conditions for the first time
Examples
-----------
Trigger an alarm when any sensors go beyond a threshold:
```
def sound\_the\_alarm do
WaitForIt.cond\_wait timeout: 60\_000 \* 60 \* 24 do
read\_sensor(:sensor1) > 9 -> IO.puts("Alarm: :sensor1 too high!")
read\_sensor(:sensor2) < 100 -> IO.puts("Alarm: :sensor2 too low!")
read\_sensor(:sensor3) < 0 -> IO.puts("Alarm: :sensor3 below zero!")
else
IO.puts("All is good...for now.")
end
sound\_the\_alarm()
end
```

signal(condition\_var)
======================
[View Source](https://github.com/jvoegele/wait_for_it/blob/master/lib/wait_for_it.ex#L277 "View Source")
(macro)
Send a signal to the given condition variable to indicate that any processes waiting on the
condition variable should re-evaluate their wait conditions.
The caller of `signal` must be in the same Elixir module as any waiters on the same condition
variable since the module is used as a namespace for condition variables. This is to prevent
accidental name collisions as well as to enforce good practice for encapsulation.
[Link to this macro](#wait/2 "Link to this macro")
wait(expression, opts \\ [])
============================
[View Source](https://github.com/jvoegele/wait_for_it/blob/master/lib/wait_for_it.ex#L94 "View Source")
(macro)
Wait until the given `expression` evaluates to a truthy value.
Returns `{:ok, value}` or `{:timeout, timeout_milliseconds}`.
Options
----------
See the WaitForIt module documentation for further discussion of these options.
* `:timeout` - the amount of time to wait (in milliseconds) before giving up
* `:frequency` - the polling frequency (in milliseconds) at which to re-evaluate conditions
* `:signal` - disable polling and use a condition variable of the given name instead
* `:pre_wait` - wait for the given number of milliseconds before evaluating conditions for the first time
Examples
-----------
Wait until the top of the hour:
```
WaitForIt.wait Time.utc\_now.minute == 0, frequency: 60\_000, timeout: 60\_000 \* 60
```
Wait up to one minute for a particular record to appear in the database:
```
case WaitForIt.wait Repo.get(Post, 42), frequency: 1000, timeout: 60\_000 do
{:ok, data} -> IO.inspect(data)
{:timeout, timeout} -> IO.puts("Gave up after #{timeout} milliseconds")
end

Raspberry Pi 3 Kiosk
====================
Implements `qt-webengine-kiosk` for rendering QtWebEngine.
This is the base Nerves System configuration for the Raspberry Pi 3 Model B.
[Image credit](#fritzing)
| Feature | Description |
| --- | --- |
| CPU | 1.2 GHz quad-core ARMv8 |
| Memory | 1 GB DRAM |
| Storage | MicroSD |
| Linux kernel | 4.19 w/ Raspberry Pi patches |
| IEx terminal | ttyS0 |
| GPIO, I2C, SPI | Yes - Elixir ALE |
| ADC | No |
| PWM | Yes, but no Elixir support |
| UART | 1 available - ttyS0 |
| Camera | Yes - via rpi-userland |
| Ethernet | Yes |
| WiFi | Yes - Nerves.InterimWiFi |
| Bluetooth | Not yet |
Using
--------
The most common way of using this Nerves System is create a project with `mix nerves.new` and to export `MIX_TARGET=rpi3`.
Then, change the rpi3 system dependency to
`{:kiosk_system_rpi3, "~> 1.0"}`
See the [Getting started
guide](https://hexdocs.pm/nerves/getting-started.html#creating-a-new-nerves-app)
for more information.
If you need custom modifications to this system for your device, clone this
repository and update as described in [Making custom
systems](https://hexdocs.pm/nerves/systems.html#customizing-your-own-nerves-system)
See the [example project](https://github.com/LeToteTeam/kiosk_system_rpi3/tree/master/example) for more info
Built-in WiFi Firmware
-------------------------
WiFi modules almost always require proprietary firmware to be loaded for them to work. The
Linux kernel handles this and firmware blobs are maintained in the
`linux-firmware` project. The firmware for the built-in WiFi module on the RPi3
hasn't made it to the `linux-firmware` project nor Buildroot, so it is included
here in a `rootfs-additions` overlay directory. The original firmware files came from
<https://github.com/RPi-Distro/firmware-nonfree/blob/master/brcm80211/brcm>.
[Image credit](#fritzing): This image is from the [Fritzing](http://fritzing.org/home/) parts library.
Provisioning devices
-----------------------
This system supports storing provisioning information in a small key-value store
outside of any filesystem. Provisioning is an optional step and reasonable
defaults are provided if this is missing.
Provisioning information can be queried using the Nerves.Runtime KV store's
[`Nerves.Runtime.KV.get/1`](https://hexdocs.pm/nerves_runtime/Nerves.Runtime.KV.html#get/1)
function.
Keys used by this system are:
| Key | Example Value | Description |
| --- | --- | --- |
| `nerves_serial_number` | "1234578"` | By default, this string is used to create unique hostnames and Erlang node names. If unset, it defaults to part of the Raspberry Pi's device ID. |
The normal procedure would be to set these keys once in manufacturing or before
deployment and then leave them alone.
For example, to provision a serial number on a running device, run the following
and reboot:
```
iex> cmd("fw\_setenv nerves\_serial\_number 1234")
```
This system supports setting the serial number offline. To do this, set the
`NERVES_SERIAL_NUMBER` environment variable when burning the firmware. If you're
programming MicroSD cards using `fwup`, the commandline is:
```
sudo NERVES_SERIAL_NUMBER=1234 fwup path_to_firmware.fw
```
Serial numbers are stored on the MicroSD card so if the MicroSD card is
replaced, the serial number will need to be reprogrammed. The numbers are stored
in a U-boot environment block. This is a special region that is separate from
the application partition so reformatting the application partition will not
lose the serial number or any other data stored in this block.

> GitHub OAuth2 strategy for Γberauth.
>
>
Installation
---------------
1. Setup your application at [GitHub Developer](https://developer.github.com).
2. Add `:ueberauth_github` to your list of dependencies in `mix.exs`:
```
def deps do
[
{:ueberauth\_github, "~> 0.8"}
]
end
```
3. Add GitHub to your Γberauth configuration:
```
config :ueberauth, Ueberauth,
providers: [
github: {Ueberauth.Strategy.Github, []}
]
```
4. Update your provider configuration:
```
config :ueberauth, Ueberauth.Strategy.Github.OAuth,
client\_id: System.get\_env("GITHUB\_CLIENT\_ID"),
client\_secret: System.get\_env("GITHUB\_CLIENT\_SECRET")
```
Or, to read the client credentials at runtime:
```
config :ueberauth, Ueberauth.Strategy.Github.OAuth,
client\_id: {:system, "GITHUB\_CLIENT\_ID"},
client\_secret: {:system, "GITHUB\_CLIENT\_SECRET"}
```
5. Include the Γberauth plug in your router:
```
defmodule MyApp.Router do
use MyApp.Web, :router
pipeline :browser do
plug Ueberauth
...
end
end
```
6. Create the request and callback routes if you haven't already:
```
scope "/auth", MyApp do
pipe\_through :browser
get "/:provider", AuthController, :request
get "/:provider/callback", AuthController, :callback
end
```
7. Your controller needs to implement callbacks to deal with [`Ueberauth.Auth`](https://hexdocs.pm/ueberauth/0.10.3/Ueberauth.Auth.html)
and [`Ueberauth.Failure`](https://hexdocs.pm/ueberauth/0.10.3/Ueberauth.Failure.html) responses.
For an example implementation see the [Γberauth Example](https://github.com/ueberauth/ueberauth_example) application.
Calling
----------
Depending on the configured url you can initiate the request through:
```
/auth/github
```
Or with options:
```
/auth/github?scope=user,public\_repo
```
By default the requested scope is `"user,public\_repo"`. This provides both read
and write access to the GitHub user profile details and public repos. For a
read-only scope, either use `"user:email"` or an empty scope `""`. Empty scope
will only request minimum public information which even excludes user's email address
which results in a `nil` for `email` inside returned `%Ueberauth.Auth.Info{}`.
See more at [GitHub's OAuth Documentation](https://developer.github.com/apps/building-integrations/setting-up-and-registering-oauth-apps/about-scopes-for-oauth-apps/).
Scope can be configured either explicitly as a `scope` query value on the
request path or in your configuration:
```
config :ueberauth, Ueberauth,
providers: [
github: {Ueberauth.Strategy.Github, [default\_scope: "user,public\_repo,notifications"]}
]
```
It is also possible to disable the sending of the `redirect_uri` to GitHub.
This is particularly useful when your production application sits behind a
proxy that handles SSL connections. In this case, the `redirect_uri` sent by
[`Ueberauth`](https://hexdocs.pm/ueberauth/0.10.3/Ueberauth.html) will start with `http` instead of `https`, and if you configured
your GitHub OAuth application's callback URL to use HTTPS, GitHub will throw an
`uri_mismatch` error.
To prevent [`Ueberauth`](https://hexdocs.pm/ueberauth/0.10.3/Ueberauth.html) from sending the `redirect_uri`, you should add the
following to your configuration:
```
config :ueberauth, Ueberauth,
providers: [
github: {Ueberauth.Strategy.Github, [send\_redirect\_uri: false]}
]
```
Private Emails
-----------------
GitHub now allows you to keep your email address private. If you don't mind
that you won't know a users email address you can specify
`allow_private_emails`. This will set the users email as
`id+username@users.noreply.github.com`.
```
config :ueberauth, Ueberauth,
providers: [
github: {Ueberauth.Strategy.Github, [allow\_private\_emails: true]}
]
```

Ueberauth.Strategy.Github (Γeberauth GitHub v0.8.3)
[View Source](https://github.com/ueberauth/ueberauth_github/blob/#v{@version}/lib/ueberauth/strategy/github.ex#L1 "View Source")
=====================================================================================================================================================================================
Provides an Ueberauth strategy for authenticating with GitHub.
###
Setup
Create an application in Github for you to use.
Register a new application at: [your github developer page](https://github.com/settings/developers)
and get the `client_id` and `client_secret`.
Include the provider in your configuration for Ueberauth;
```
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [] }
]
```
Then include the configuration for GitHub:
```
config :ueberauth, Ueberauth.Strategy.Github.OAuth,
client\_id: System.get\_env("GITHUB\_CLIENT\_ID"),
client\_secret: System.get\_env("GITHUB\_CLIENT\_SECRET")
```
If you haven't already, create a pipeline and setup routes for your callback handler
```
pipeline :auth do
Ueberauth.plug "/auth"
end
scope "/auth" do
pipe\_through [:browser, :auth]
get "/:provider/callback", AuthController, :callback
end
```
Create an endpoint for the callback where you will handle the
[`Ueberauth.Auth`](https://hexdocs.pm/ueberauth/0.10.3/Ueberauth.Auth.html) struct:
```
defmodule MyApp.AuthController do
use MyApp.Web, :controller
def callback\_phase(%{ assigns: %{ ueberauth\_failure: fails } } = conn, \_params) do
# do things with the failure
end
def callback\_phase(%{ assigns: %{ ueberauth\_auth: auth } } = conn, params) do
# do things with the auth
end
end
```
You can edit the behaviour of the Strategy by including some options when you
register your provider.
To set the `uid_field`:
```
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [uid\_field: :email] }
]
```
Default is `:id`.
To set the default 'scopes' (permissions):
```
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [default\_scope: "user,public\_repo"] }
]
```
Default is empty ("") which "Grants read-only access to public information
(includes public user profile info, public repository info, and gists)"

Svelte handles the look and feel of the chat, while LiveView takes care of syncing. E2E reactivity to the Svelte component so we don't really need to fetch anything! The 'login' to enter your name is a simple LiveView form. Hybrid!

News items are synced with the server while the speed is only client side.
[why-livesvelte](#why-livesvelte)
Why LiveSvelte
--------------------------------------------------
Phoenix LiveView enables rich, real-time user experiences with server-rendered HTML.
It works by communicating any state changes through a websocket and updating the DOM in realtime.
You can get a really good user experience without ever needing to write any client side code.
LiveSvelte builds on top of Phoenix LiveView to allow for easy client side state management while still allowing for communication over the websocket.
###
[reasons-why-you-d-use-livesvelte](#reasons-why-you-d-use-livesvelte)
Reasons why you'd use LiveSvelte
* You have (complex) local state
* You want to take full advantage of Javascript's ecosystem
* You want to take advantage of Svelte's animations
* You want scoped CSS
* You like Svelte and its DX :)
[requirements](#requirements)
Requirements
--------------------------------------------
For Server-Side Rendering (SSR) to work you need `node` (version 19 or later) installed in your environment.
Make sure you have it installed in production too. You might be using `node` in the build step, but it might actually not be installed in your production environment.
You can make sure you have `node` installed by running `node --version` in your project directory.
If you don't want SSR, you can disable it by not setting [`NodeJS.Supervisor`](https://hexdocs.pm/nodejs/2.0.0/NodeJS.Supervisor.html) in `application.ex`. More on that in the [SSR](#ssr-server-side-rendering) section of this document.
[installation](#installation)
Installation
--------------------------------------------
*If you're updating from an older version, make sure to check the `CHANGELOG.md` for breaking changes.*
1. Add `live_svelte` to your list of dependencies in `mix.exs`:
```
defp deps do
[
{:live\_svelte, "~> 0.12.0"}
]
end
```
2. Adjust the `setup` and `assets.deploy` aliases in `mix.exs`:
```
defp aliases do
[
setup: ["deps.get", "ecto.setup", "cmd --cd assets npm install"],
...,
"assets.deploy": ["cmd --cd assets node build.js --deploy", "phx.digest"]
]
end
```
3. Run the following in your terminal
```
mix deps.get
mix live\_svelte.setup
```
4. Add `import LiveSvelte` in `html_helpers/0` inside `/lib/<app_name>_web.ex` like so:
```
# /lib/<app\_name>\_web.ex
defp html\_helpers do
quote do
# ...
import LiveSvelte # <-- Add this line
# ...
end
end
```
5. For tailwind support, add `"./svelte/**/*.svelte"` to `content` in the `tailwind.config.js` file
```
...
content: [
...
"./svelte/**/*.svelte"
],
...
```
6. Finally, remove the `esbuild` configuration from `config/config.exs` and remove the dependency from the `deps` function in your `mix.exs`, and you are done!
###
[what-did-we-do](#what-did-we-do)
What did we do?
You'll notice a bunch of files get created in `/assets`, as well as some code changes in `/lib`. This mostly follows from the recommended way of using esbuild plugins, which we need to make this work. You can read more about this here: <https://hexdocs.pm/phoenix/asset_management.html#esbuild-plugins>
In addition we commented out some things such as the `esbuild` watcher configured in `dev.exs` that won't be needed anymore, you can delete these comments if desired.
[usage](#usage)
Usage
-----------------------
Svelte components need to go into the `assets/svelte` directory
Attributes:
* `name`: Specify the Svelte component
* `props` *(Optional)*: Provide the `props` you want to use that should be reactive as a map to the props field
* `class` *(Optional)*: Provide `class` to set the class attribute on the root svelte element
* `ssr` *(Optional)*: Set `ssr` to `false` to disable server-side rendering
e.g. If your component is named `assets/svelte/Example.svelte`:
```
def render(assigns) do
~H"""
<.svelte name="Example" props={%{number: @number}} socket={@socket} />
"""
end
```
If your component is in a directory, for example `assets/svelte/some-directory/SomeComponent.svelte` you need to include the directory in your name: `some-directory/SomeComponent`.
###
[the-components-macro](#the-components-macro)
The Components Macro
There is also an Elixir macro which checks your `assets/svelte` folder for any Svelte components, and injects local function `def`s for those components into the calling module.
This allows for an alternative, more JSX-like authoring experience inside Liveviews.
e.g. in the below example, a Svelte component called `Example` is available to be called inside the Liveview template:
```
use LiveSvelte.Components
def render(assigns) do
~H"""
<.Example number={@number} socket={@socket} />
"""
end
```
###
[examples](#examples)
Examples
Examples can be found in the `/examples` and `/example_project` directories.
Most of the `/example_project` examples are visible in the [YouTube demo video](https://www.youtube.com/watch?v=JMkvbW35QvA).
I recommend cloning `live_svelte` and running the example project in `/example_project` by running the following commands:
```
git clone https://github.com/woutdp/live\_svelte.git
cd ./live\_svelte/example\_project
npm install --prefix assets
mix deps.get
mix phx.server
```
Server should be running on `localhost:4000`
If you have examples you want to add, feel free to create a PR, I'd be happy to add them.
#### Create a Svelte component
```
<script>
// The number prop is reactive,
// this means if the server assigns the number, it will update in the frontend
export let number = 1
// live contains all exported LiveView methods available to the frontend
export let live
function increase() {
// This pushes the event over the websocket
// The last parameter is optional. It's a callback for when the event is finished.
// You could for example set a loading state until the event is finished if it takes a longer time.
live.pushEvent("set_number", {number: number + 1}, () => {})
// Note that we actually never set the number in the frontend!
// We ONLY push the event to the server.
// This is the E2E reactivity in action!
// The number will automatically be updated through the LiveView websocket
}
function decrease() {
pushEvent("set_number", {number: number - 1}, () => {})
}
</script>
<p>The number is {number}</p>
<button on:click={increase}>+</button>
<button on:click={decrease}>-</button>
```
*Note: that here we use the `pushEvent` function, but you could also use `phx-click` and `phx-value-number` if you wanted.*
The following methods are available on `live`:

#### Create a LiveView
```
# `/lib/app\_web/live/live\_svelte.ex`
defmodule AppWeb.SvelteLive do
use AppWeb, :live\_view
def render(assigns) do
~H"""
<.svelte name="Example" props={%{number: @number}} socket={@socket} />
"""
end
def handle\_event("set\_number", %{"number" => number}, socket) do
{:noreply, assign(socket, :number, number)}
end
def mount(\_params, \_session, socket) do
{:ok, assign(socket, :number, 5)}
end
end
```
```

[livesvelte-as-an-alternative-liveview-dsl](#livesvelte-as-an-alternative-liveview-dsl)
LiveSvelte As An Alternative LiveView DSL
[Blogpost on the topic](https://wout.space/notes/live-svelte-as-liveview-dsl)
We can go one step further and use LiveSvelte as an alternative to the standard LiveView DSL. This idea is inspired by [Surface UI](https://surface-ui.org/).
Take a look at the following example:
```
defmodule ExampleWeb.LiveSigil do
use ExampleWeb, :live\_view
def render(assigns) do
~V"""
<script>
export let number = 5
let other = 1
$: combined = other + number
</script>
<p>This is number: {number}</p>
<p>This is other: {other}</p>
<p>This is other + number: {combined}</p>
<button phx-click="increment">Increment</button>
<button on:click={() => other += 1}>Increment</button>
"""
end
def mount(\_params, \_session, socket) do
{:ok, assign(socket, :number, 1)}
end
def handle\_event("increment", \_value, socket) do
{:noreply, assign(socket, :number, socket.assigns.number + 1)}
end
end
```
Use the `~V` sigil instead of `~H` and your LiveView will be Svelte instead of an HEEx template.
#### Installation
1. If it's not already imported inside `html_helpers/0`, add `import LiveSvelte` inside the `live_view` function in your project, this can be found in `/lib/<app_name>_web.ex`:
```
def live\_view do
quote do
use Phoenix.LiveView,
layout: {ExampleWeb.Layouts, :app}
import LiveSvelte
unquote(html\_helpers())
end
end
```
2. Ignore build files in your `.gitignore`. The sigil will create Svelte files that are then picked up by `esbuild`, these files don't need to be included in your git repo:
```
# Ignore automatically generated Svelte files by the ~V sigil
/assets/svelte/_build/
```
#### Neovim Treesitter Config
To enable syntax highlighting in Neovim with Treesitter, create the following file:
`~/.config/nvim/after/queries/elixir/injections.scm`
```
; extends
; Svelte
(sigil
(sigil\_name) @\_sigil\_name
(quoted\_content) @svelte
(#eq? @\_sigil\_name "V"))
```
Also make sure Svelte and Elixir is installed in Treesitter.
#### Options
Options can be passed in the mount by setting `svelte_opts`, check the following example:
```
def mount(\_params, \_session, socket) do
{:ok, assign(socket, some\_value: 1, svelte\_opts: %{ssr: false, class: "example-class"})}
end
```
###
[liveview-live-navigation-events](#liveview-live-navigation-events)
LiveView Live Navigation Events
Inside Svelte you can define [Live Navigation](https://hexdocs.pm/phoenix_live_view/live-navigation.html) links. These links navigate from one LiveView to the other without refreshing the page.
For example this can be useful when you have a Svelte store and you want this store state to remain during navigation. Example of Svelte store usage can be found in `/examples/store`.
`push_navigate`
```
<a href="/your-liveview-path" data-phx-link="redirect" data-phx-link-state="push">Redirect</a>
```
`push_patch`
```
<a href="/your-liveview-path" data-phx-link="patch" data-phx-link-state="push">Patch</a>
```

###
[ssr-server-side-rendering](#ssr-server-side-rendering)
SSR (Server-Side Rendering)
If you're unfamiliar with SSR (Server-Side Rendering), it is a feature of Svelte to... render Svelte on the server. This means on first page load you get to see HTML instead of a blank page. Immediately after the first page load the page is '[hydrated](https://www.youtube.com/watch?v=D46aT3mx9LU)', which is a fancy word for adding reactivity to your component. This happens in the background, you don't notice this step happening.
The way LiveSvelte updates itself through LiveView is by letting Svelte handle all the HTML edits. Usually LiveView would edit the HTML by passing messages through the websocket. In our case we only pass the data we provided in the props attribute to Svelte through the websocket. No HTML is being touched by LiveView, Svelte takes care of that.
Like mentioned, without SSR you'd see a brief flash of un-rendered content. Sometimes you can get away with not rendering Svelte on the server, for example when your Svelte component doesn't do any rendering on first page load and needs to be manually toggled for visibility by the user. Or when it is a component that has no visual component to it like tracking your mouse cursor and sending it back to the server.
In theses cases you can turn off SSR.
#### Disabling SSR
SSR is enabled by default when you install LiveSvelte. If you don't want to use Server-Side Rendering for Svelte, you have 2 options:
##### Globally
If you don't want to use SSR on any component you can disable it globally.
This will automatically be the case if you don't include the [`NodeJS`](https://hexdocs.pm/nodejs/2.0.0/NodeJS.html) supervisor in the `application.ex` file
##### Component
To disable SSR on a specific component, set the `ssr` property to false. Like so:
```
<.svelte name="Example" ssr={false} />
```
###
[live\_json](#live_json)
live\_json
LiveSvelte has support for [live\_json](https://github.com/Miserlou/live_json).
By default, LiveSvelte sends your entire json object over the wire through LiveView. This can be expensive if your json object is big and changes frequently.
`live_json` on the other hand allows you to only send a *diff* of the json to Svelte. This is very useful the bigger your json objects get.
Counterintuitively, you don't always want to use `live_json`. Sometimes it's cheaper to send your entire object again. Although diffs are small, they do add a little bit of data to your json. So if your json is relatively small, I'd recommend not using `live_json`, but it's something to experiment with for your use-case.
#### Usage
1. Install [live\_json](https://github.com/Miserlou/live_json#installation)
2. Use `live_json` in your project with LiveSvelte. For example:
```
def render(assigns) do
~H"""
<.svelte name="Component" live\_json\_props={%{my\_prop: @ljmy\_prop}} socket={@socket} />
"""
end
def mount(\_, \_, socket) do
# Get `my\_big\_json\_object` somehow
{:ok, LiveJson.initialize("my\_prop", my\_big\_json\_object)}
end
def handle\_info(%Broadcast{event: "update", payload: my\_big\_json\_object}, socket) do
{:noreply, LiveJson.push\_patch(socket, "my\_prop", my\_big\_json\_object)}
end
```
#### Example
You can find an example [here](https://github.com/woutdp/live_svelte/blob/master/example_project/lib/example_web/live/live_json.ex).
###
[structs-and-ecto](#structs-and-ecto)
Structs and Ecto
We use [Jason](https://github.com/michalmuskala/jason) to serialize any data you pass in the props so it can be handled by Javascript.
Jason doesn't know how to handle structs by default, so you need to define it yourself.
#### Structs
For example, if you have a regular struct like this:
```
defmodule User do
defstruct name: "John", age: 27, address: "Main St"
end
```
You must define `@derive`
```
defmodule User do
@derive Jason.Encoder
defstruct name: "John", age: 27, address: "Main St"
end
```
Be careful though, as you might accidentally leak certain fields you don't want the client to access, you can include which fields to serialize:
```
defmodule User do
@derive {Jason.Encoder, only: [:name, :age]}
defstruct name: "John", age: 27, address: "Main St"
end
```
#### Ecto
In ecto's case it's important to *also* omit the `__meta__` field as it's not serializable.
Check out the following example:
```
defmodule Example.Planets.Planet do
use Ecto.Schema
import Ecto.Changeset
@derive {Jason.Encoder, except: [:\_\_meta\_\_]}
schema "planets" do
field :diameter, :integer
field :mass, :integer
field :name, :string
timestamps()
end
...
end
```

###
[slot-interoperability](#slot-interoperability)
Slot Interoperability
Slot interoperability is still experimental, **so use with caution!**
Svelte doesn't have an official way of setting the slot on mounting the Svelte object or updating it on subsequent changes, unlike props. This makes using slots from within Liveview on a Svelte component fragile.
The server side rendered initial Svelte rendering does have support for slots so that should work as expected.
Slots may eventually reach a state where it is stable, any help in getting there is appreciated. If you know a lot about the internals of Svelte your help may be invaluable here!
Any bugs related to this are welcome to be logged, PR's are especially welcome!
###
[secret-state](#secret-state)
"Secret State"
With LiveView, it's easy to keep things secret. Let's say you have a conditional that only renders when something is `true`, in LiveView there's no way to know what that conditional will show until it is shown, that's because the HTML is sent over the wire.
With LiveSvelte, we're dealing with JSON being sent to Svelte, which in turn takes that JSON data and conditionally renders something, even if we don't set the conditional to `true`, the Svelte code will contain code on what to show when the conditional turns `true`.
In a lot of scenarios this is not an issue, but it can be and is something you should be aware of.

TelemetryUI
(telemetry\_ui v4.1.0)
======================================================================================================================================================
Main entry point to start all the processes as part of your application.
Usage
=====
```
use Application
def start(\_type, \_args) do
children = [
Shopcast.Repo,
MyAppWeb.Endpoint,
{TelemetryUI, my\_config()}
]
```
The reporter, write buffer and pruner processes will be part of your supervision tree, ensuring that everything runs smoothly.
The config is a data structure representing all settings used by TelemetryUI.
[Config example](#module-config-example)
-----------------------------------------
```
[
metrics: [
{"System", [last\_value("vm.memory.total", unit: {:byte, :megabyte})]}
],
theme: %{title: "Metrics"},
backend:
%TelemetryUI.Backend.EctoPostgres{
repo: MyApp.Repo,
pruner\_threshold: [months: -1],
pruner\_interval\_ms: 3\_600\_000,
max\_buffer\_size: 1\_000,
flush\_interval\_ms: 10\_000
}
]
```
This config will show a basic "last value" chart for the memory usage reported by the VM.
The title of the page will be "Metrics" and the backend used to store and query metrics will be PostgreSQL.
See [`TelemetryUI.Config`](TelemetryUI.Config.html) for a list of all options.
[Metrics list](#module-metrics-list)
-------------------------------------
Every kind of metrics exposed by `TelemetryMetrics` is supported by [`TelemetryUI`](TelemetryUI.html#content):
* `last_value`
* `summary`
* `sum`
* `counter`
* `distribution`
[`TelemetryUI`](TelemetryUI.html#content) also exposes its own set of metrics:
* `average`
* `average_over_time`
* `count_over_time`
* `median`
* `median_over_time`
[The Web](#module-the-web)
---------------------------
Finally, when the configuration is done and we actually want to see our metrics, we need to add the [`TelemetryUI.Web`](TelemetryUI.Web.html) module in our router:
*Phoenix*
```
scope "/" do
pipe\_through([:browser])
get("/metrics", TelemetryUI.Web, [], [assigns: %{telemetry\_ui\_allowed: true}])
end
```
The metrics page is protected by default. It needs to have the `telemetry_ui_allowed` assign to true to render.
We can imagine having a `:admin_protected` plug that ensure a user is an admin and also assign `telemetry_ui_allowed` to true.
```
scope "/" do
pipe\_through([:browser, :admin\_protected])
get("/metrics", TelemetryUI.Web, [])
end
```
Thatβs it! The `/metrics` page will show the metrics as they are recorded. Checkout the Guides to dive into more complex configuration and awesome features :)

(telemetry\_ui v4.1.0)
=======================================================================================================================================================================================
Inserting, fetching and pruning of metrics.
[Inserting](#module-inserting)
-------------------------------
Inserting is called by the internal `WriteBuffer`. It can be grouped depending on the buffer configuration inside the backend struct:
* `flush_interval_ms`: Time interval before the write buffer calls the backend
* `max_buffer_size`: Maximum count of events before the write buffer calls the backend
[Fetching](#module-fetching)
-----------------------------
Fetching is called when rendering metrics in the view. The `filters` argument is a struct with predefined fields: `to`, `from`, `event_name` and `compare`.
[Pruning](#module-pruning)
---------------------------
Pruning is implemented to keep the datastore clean. Keeping data forever will increase the size of the storage and affect performance.
* `pruner_threshold`: *Example:* `[months: -1]`. Delete events older than a month.
* `pruner_interval_ms`: *Example:* 84\_000. Time interval for the pruner process to run. The process simply calls `#prune_events!/2`.

TelemetryUI.Backend.EctoPostgres.Migrations
(telemetry\_ui v4.1.0)
=======================================================================================================================================================================================================================
Migrations create and modify the database tables TelemetryUI needs to function.
[Usage](#module-usage)
-----------------------
To use migrations in your application you'll need to generate an [`Ecto.Migration`](https://hexdocs.pm/ecto_sql/3.10.1/Ecto.Migration.html) that wraps
calls to [`TelemetryUI.Backend.EctoPostgres.Migrations`](TelemetryUI.Backend.EctoPostgres.Migrations.html#content):
```
mix ecto.gen.migration add\_telemetry\_ui
```
Open the generated migration in your editor and call the `up` and `down` functions on
[`TelemetryUI.Backend.EctoPostgres.Migrations`](TelemetryUI.Backend.EctoPostgres.Migrations.html#content):
```
defmodule MyApp.Repo.Migrations.AddTelemetryUI do
use Ecto.Migration
def up, do: TelemetryUI.Backend.EctoPostgres.Migrations.up()
def down, do: TelemetryUI.Backend.EctoPostgres.Migrations.down()
end
```
This will run all of TelemetryUI's versioned migrations for your database.
Now, run the migration to create the table:
```
mix ecto.migrate
```
Migrations between versions are idempotent. As new versions are released, you
may need to run additional migrations. To do this, generate a new migration:
```
mix ecto.gen.migration upgrade\_telemetry\_ui\_to\_v11
```
Open the generated migration in your editor and call the `up` and `down`
functions on [`TelemetryUI.Backend.EctoPostgres.Migrations`](TelemetryUI.Backend.EctoPostgres.Migrations.html#content), passing a version number:
```
defmodule MyApp.Repo.Migrations.UpgradeTelemetryUIToV11 do
use Ecto.Migration
def up, do: TelemetryUI.Backend.EctoPostgres.Migrations.up(version: 11)
def down, do: TelemetryUI.Backend.EctoPostgres.Migrations.down(version: 11)
end
```
[Isolation with Prefixes](#module-isolation-with-prefixes)
-----------------------------------------------------------
TelemetryUI supports namespacing through PostgreSQL schemas, also called "prefixes" in Ecto. With
prefixes your events table can reside outside of your primary schema (usually public) and you can
have multiple separate job tables.
To use a prefix you first have to specify it within your migration:
```
defmodule MyApp.Repo.Migrations.AddPrefixedTelemetryUIJobsTable do
use Ecto.Migration
def up, do: TelemetryUI.Backend.EctoPostgres.Migrations.up(prefix: "private")
def down, do: TelemetryUI.Backend.EctoPostgres.Migrations.down(prefix: "private")
end
```
The migration will create the "private" schema and all tables, functions and triggers within
that schema. With the database migrated you'll then specify the prefix in your configuration:
```
config :my\_app, TelemetryUI,
prefix: "private",
...
```
In some cases, for example if your "private" schema already exists and your database user in
production doesn't have permissions to create a new schema, trying to create the schema from the
migration will result in an error. In such situations, it may be useful to inhibit the creation

Telemetry-based metrics UI. Take your [`telemetry`](https://github.com/beam-telemetry/telemetry) metrics and display them in a web page.
[](https://hex.pm/packages/telemetry_ui)
[Features](#features)
----------------------
[`TelemetryUI`](TelemetryUI.html)βs primary goal is to display [your application metrics](https://hexdocs.pm/telemetry_metrics) without external infrastructure dependencies. [Plug](https://hexdocs.pm/plug/Plug.Telemetry.html), [Phoenix](https://hexdocs.pm/phoenix/telemetry.html), [Phoenix LiveView](https://hexdocs.pm/phoenix_live_view/telemetry.html), [Absinthe](https://hexdocs.pm/absinthe/telemetry.html), [Ecto](https://hexdocs.pm/ecto/Ecto.Repo.html#module-telemetry-events), [Erlang VM](https://hexdocs.pm/telemetry_poller/readme.html), [Tesla](https://hexdocs.pm/tesla/Tesla.Middleware.Telemetry.html), [Finch](https://hexdocs.pm/finch/Finch.Telemetry.html), [Redix](https://hexdocs.pm/redix/telemetry.html), [Oban](https://hexdocs.pm/oban/Oban.Telemetry.html), [Broadway](https://hexdocs.pm/broadway/Broadway.html#module-telemetry) and others expose all sorts of data that can be useful. You can also emit your own events from your application.
Your data should not have to be uploaded somewhere else to have insighful metrics.
It comes with a Postgres backend, powered by [Ecto](https://hexdocs.pm/ecto), to quickly (and efficiently) store and query your application events.
###
[Advantages over other tools](#advantages-over-other-tools)
* Persisted metrics inside your own database
* Live dashboard
* Many built-in charts and visualizations using [VegaLite](https://vega.github.io/vega-lite/)
###
[Advanced features](#advanced-features)
* 100% custom UI hook to show your own components
* 100% custom data fetching to show live data
* Shareable metrics page (secured, cacheable, without external requests)
* Slack digest with rendered images
* Multiple metrics dashboard living in the same app
Checkout the Guides for more informations.
[Usage](#usage)
----------------
###
[Installation](#installation)
TelemetryUI is published on Hex. Add it to your list of dependencies in `mix.exs`:
```
# mix.exs
def deps do
[
{:telemetry\_ui, "~> 4.0"}
]
end
```
Then run mix deps.get to install Telemetry and its dependencies.
After the packages are installed you must create a database migration to add the `telemetry_ui_events` table to your database:
```
mix ecto.gen.migration add\_telemetry\_ui\_events\_table
```
Open the generated migration in your editor and call the up and down functions on `TelemetryUI.Adapter.EctoPostgres.Migrations`:
```
defmodule MyApp.Repo.Migrations.AddTelemetryUIEventsTable do
use Ecto.Migration
def up do
TelemetryUI.Backend.EctoPostgres.Migrations.up()
end
# We specify `version: 1` in `down`, ensuring that we'll roll all the way back down if
# necessary, regardless of which version we've migrated `up` to.
def down do
TelemetryUI.Backend.EctoPostgres.Migrations.down(version: 1)
end
end
```
This will run all of TelemetryUI's versioned migrations for your database. Migrations between versions are idempotent and rarely change after a release. As new versions are released you may need to run additional migrations.
Now, run the migration to create the table:
```
mix ecto.migrate
```
TelemetryUI instances are isolated supervision trees and must be included in your application's supervisor to run. Use the application configuration you've just set and include TelemetryUI in the list of supervised children:
```
# lib/my\_app/application.ex
def start(\_type, \_args) do
children = [
MyApp.Repo,
{TelemetryUI, telemetry\_config()}
]
Supervisor.start\_link(children, strategy: :one\_for\_one, name: MyApp.Supervisor)
end
defp telemetry\_config do
import TelemetryUI.Metrics
[
metrics: [
last\_value("my\_app.users.total\_count", description: "Number of users", ui\_options: [unit: " users"]),
counter("phoenix.router\_dispatch.stop.duration", description: "Number of requests", unit: {:native, :millisecond}, ui\_options: [unit: " requests"]),
value\_over\_time("vm.memory.total", unit: {:byte, :megabyte}),
distribution("phoenix.router\_dispatch.stop.duration", description: "Requests duration", unit: {:native, :millisecond}, reporter\_options: [buckets: [0, 100, 500, 2000]]),
],
backend: %TelemetryUI.Backend.EctoPostgres{
repo: MyApp.Repo,
pruner\_threshold: [months: -1],
pruner\_interval\_ms: 84\_000,
max\_buffer\_size: 10\_000,
flush\_interval\_ms: 10\_000
}
]
end
```
Since the config is read once at startup, you need to restart the server of you add new metrics to track.
To see the rendered metrics, you need to add a route to your router.
```
# lib/my\_app\_web/router.ex
scope "/" do
get("/metrics", TelemetryUI.Web, [], [assigns: %{telemetry\_ui\_allowed: true}])
end
```
#### Security
Since it may contain sensitive data, [`TelemetryUI`](TelemetryUI.html) requires a special assign to render the page.
`:telemetry_ui_allowed` must be set to `true` in the `conn` struct before it enters the [`TelemetryUI.Web`](TelemetryUI.Web.html) module.
By using a special assign to control access, you can integrate [`TelemetryUI.Web`](TelemetryUI.Web.html) page with your existing authorization. We can imagine an admin protected section that also gives you access to the [`TelemetryUI.Web`](TelemetryUI.Web.html) page:
```
pipeline :admin\_protected do
plug(MyAppWeb.EnsureCurrentUser)
plug(MyAppWeb.EnsureRole, :admin)
plug(:enable\_telemetry\_ui)
end
def enable\_telemetry\_ui(conn, \_), do: assign(conn, :telemetry\_ui\_allowed, true)
```
Thatβs it! You can declare as many metrics as you want and they will render in HTML on your page!

Jason
===============================================================================================================
A blazing fast JSON parser and generator in pure Elixir.
The parser and generator are at least twice as fast as other Elixir/Erlang libraries
(most notably `Poison`).
The performance is comparable to `jiffy`, which is implemented in C as a NIF.
Jason is usually only twice as slow.
Both parser and generator fully conform to
[RFC 8259](https://tools.ietf.org/html/rfc8259) and
[ECMA 404](http://www.ecma-international.org/publications/standards/Ecma-404.htm)
standards. The parser is tested using [JSONTestSuite](https://github.com/nst/JSONTestSuite).
[installation](#installation)
Installation
--------------------------------------------
The package can be installed by adding `jason` to your list of dependencies
in `mix.exs`:
```
def deps do

###
[running](#running)
Running
Benchmarks against most popular Elixir & Erlang json libraries can be executed after
going into the `bench/` folder and then executing `mix bench.encode` and `mix bench.decode`.
A HTML report of the benchmarks (after their execution) can be found in
`bench/output/encode.html` and `bench/output/decode.html` respectively.
[differences-to-poison](#differences-to-poison)
Differences to Poison
-----------------------------------------------------------------------
Jason has a couple feature differences compared to Poison.
* Jason follows the JSON spec more strictly, for example it does not allow
unescaped newline characters in JSON strings - e.g. `"\"\n\""` will
produce a decoding error.
* no support for decoding into data structures (the `as:` option).
* no built-in encoders for [`MapSet`](https://hexdocs.pm/elixir/MapSet.html), [`Range`](https://hexdocs.pm/elixir/Range.html) and [`Stream`](https://hexdocs.pm/elixir/Stream.html).
* no support for encoding arbitrary structs - explicit implementation
of the [`Jason.Encoder`](Jason.Encoder.html) protocol is always required.
* different pretty-printing customisation options (default `pretty: true` works the same)
###
[encoders](#encoders)
Encoders
If you require encoders for any of the unsupported collection types, I suggest
adding the needed implementations directly to your project:
```
defimpl Jason.Encoder, for: [MapSet, Range, Stream] do
def encode(struct, opts) do
Jason.Encode.list(Enum.to\_list(struct), opts)
end
end
```
If you need to encode some struct that does not implement the protocol,
if you own the struct, you can derive the implementation specifying
which fields should be encoded to JSON:
```
@derive {Jason.Encoder, only: [....]}
defstruct # ...
```
It is also possible to encode all fields, although this should be
used carefully to avoid accidentally leaking private information
when new fields are added:
```
@derive Jason.Encoder
defstruct # ...
```
Finally, if you don't own the struct you want to encode to JSON,
you may use [`Protocol.derive/3`](https://hexdocs.pm/elixir/Protocol.html#derive/3) placed outside of any module:
```
Protocol.derive(Jason.Encoder, NameOfTheStruct, only: [...])
Protocol.derive(Jason.Encoder, NameOfTheStruct)
```
[injecting-an-already-encoded-json-inside-a-to-be-encoded-structure](#injecting-an-already-encoded-json-inside-a-to-be-encoded-structure)
Injecting an already encoded JSON inside a to-be-encoded structure
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
If parts of the to-be-encoded structure are already JSON-encoded, you can
use [`Jason.Fragment`](Jason.Fragment.html) to mark the parts as already encoded, and avoid a
decoding/encoding roundtrip.
```
already\_encoded\_json = Jason.encode!(%{hello: "world"})
Jason.encode!(%{foo: Jason.Fragment.new(already\_encoded\_json)})
````
This feature is especially useful if you need to cache a part of the JSON,
or if it is already provided by another system (e.g. `jsonb\_agg` with Postgres).

```
Parses a JSON value from `input` iodata.
[options](#decode/2-options)
Options
--------------------------------------
* `:keys` - controls how keys in objects are decoded. Possible values are:
+ `:strings` (default) - decodes keys as binary strings,
+ `:atoms` - keys are converted to atoms using [`String.to_atom/1`](https://hexdocs.pm/elixir/String.html#to_atom/1),
+ `:atoms!` - keys are converted to atoms using [`String.to_existing_atom/1`](https://hexdocs.pm/elixir/String.html#to_existing_atom/1),
+ custom decoder - additionally a function accepting a string and returning a key
is accepted.
* `:strings` - controls how strings (including keys) are decoded. Possible values are:
+ `:reference` (default) - when possible tries to create a sub-binary into the original
+ `:copy` - always copies the strings. This option is especially useful when parts of the
decoded data will be stored for a long time (in ets or some process) to avoid keeping
the reference to the original data.
* `:floats` - controls how floats are decoded. Possible values are:
+ `:native` (default) - Native conversion from binary to float using [`:erlang.binary_to_float/1`](https://www.erlang.org/doc/man/erlang.html#binary_to_float-1),
+ `:decimals` - uses [`Decimal.new/1`](https://hexdocs.pm/decimal/2.0.0/Decimal.html#new/1) to parse the binary into a Decimal struct with arbitrary precision.
* `:objects` - controls how objects are decoded. Possible values are:
+ `:maps` (default) - objects are decoded as maps
+ `:ordered_objects` - objects are decoded as [`Jason.OrderedObject`](Jason.OrderedObject.html) structs
[decoding-keys-to-atoms](#decode/2-decoding-keys-to-atoms)
Decoding keys to atoms
-----------------------------------------------------------------------------------
The `:atoms` option uses the [`String.to_atom/1`](https://hexdocs.pm/elixir/String.html#to_atom/1) call that can create atoms at runtime.
Since the atoms are not garbage collected, this can pose a DoS attack vector when used
on user-controlled data.

Generates JSON corresponding to `input`.
The generation is controlled by the [`Jason.Encoder`](Jason.Encoder.html) protocol,
please refer to the module to read more on how to define the protocol
for custom data types.
[options](#encode/2-options)
Options
--------------------------------------
* `:escape` - controls how strings are encoded. Possible values are:
+ `:json` (default) - the regular JSON escaping as defined by RFC 7159.
+ `:javascript_safe` - additionally escapes the LINE SEPARATOR (U+2028)
and PARAGRAPH SEPARATOR (U+2029) characters to make the produced JSON
valid JavaScript.
+ `:html_safe` - similar to `:javascript_safe`, but also escapes the `/`
character to prevent XSS.
+ `:unicode_safe` - escapes all non-ascii characters.
* `:maps` - controls how maps are encoded. Possible values are:
+ `:strict` - checks the encoded map for duplicate keys and raises
if they appear. For example `%{:foo => 1, "foo" => 2}` would be
rejected, since both keys would be encoded to the string `"foo"`.
+ `:naive` (default) - does not perform the check.
* `:pretty` - controls pretty printing of the output. Possible values are:
+ `true` to pretty print with default configuration
+ a keyword of options as specified by [`Jason.Formatter.pretty_print/2`](Jason.Formatter.html#pretty_print/2).

Generates JSON corresponding to `input` and returns iodata.
This function should be preferred to [`encode/2`](#encode/2), if the generated

Jason.Encoder protocol
(jason v1.4.1)
====================================================================================================================================================
Protocol controlling how a value is encoded to JSON.
[deriving](#module-deriving)
Deriving
---------------------------------------
The protocol allows leveraging the Elixir's `@derive` feature
to simplify protocol implementation in trivial cases. Accepted
options are:
* `:only` - encodes only values of specified keys.
* `:except` - encodes all struct fields except specified keys.
By default all keys except the `:__struct__` key are encoded.
[example](#module-example)
Example
------------------------------------
Let's assume a presence of the following struct:
```
defmodule Test do
defstruct [:foo, :bar, :baz]
end
```
If we were to call `@derive Jason.Encoder` just before `defstruct`,
an implementation similar to the following implementation would be generated:
```
defimpl Jason.Encoder, for: Test do
def encode(value, opts) do
Jason.Encode.map(Map.take(value, [:foo, :bar, :baz]), opts)
end
end
```
If we called `@derive {Jason.Encoder, only: [:foo]}`, an implementation
similar to the following implementation would be generated:
```
defimpl Jason.Encoder, for: Test do
def encode(value, opts) do
Jason.Encode.map(Map.take(value, [:foo]), opts)
end
end
```
If we called `@derive {Jason.Encoder, except: [:foo]}`, an implementation
similar to the following implementation would be generated:
```
defimpl Jason.Encoder, for: Test do
def encode(value, opts) do
Jason.Encode.map(Map.take(value, [:bar, :baz]), opts)
end
end
```
The actually generated implementations are more efficient computing some data
during compilation similar to the macros from the [`Jason.Helpers`](Jason.Helpers.html) module.
[explicit-implementation](#module-explicit-implementation)
Explicit implementation
------------------------------------------------------------------------------------
If you wish to implement the protocol fully yourself, it is advised to
use functions from the [`Jason.Encode`](Jason.Encode.html) module to do the actual iodata
generation - they are highly optimized and verified to always produce
valid JSON.

```
Minimizes JSON-encoded `input` and returns iodata.
This function should be preferred to [`minimize/2`](#minimize/2), if the minimized
JSON will be handed over to one of the IO functions or sent
over the socket. The Erlang runtime is able to leverage vectorised
writes and avoid allocating a continuous buffer for the whole
resulting string, lowering memory use and increasing performance.

```
Pretty-prints JSON-encoded `input`.
`input` may contain multiple JSON objects or arrays, optionally separated
by whitespace (e.g., one object per line). Objects in output will be
separated by newlines. No trailing newline is emitted.
[options](#pretty_print/2-options)
Options
--------------------------------------------
* `:indent` - used for nested objects and arrays (default: two spaces - `" "`);
* `:line_separator` - used in nested objects (default: `"\n"`);
* `:record_separator` - separates root-level objects and arrays
(default is the value for `:line_separator` option);
* `:after_colon` - printed after a colon inside objects (default: one space - `" "`).

=============================================================================================================================================
Provides a way to inject an already-encoded JSON structure into a
to-be-encoded structure in optimized fashion.
This avoids a decoding/encoding round-trip for the subpart.
This feature can be used for caching parts of the JSON, or delegating
the generation of the JSON to a third-party system (e.g. Postgres).

Provides macro facilities for partial compile-time encoding of JSON.
[Link to this section](#summary)
Summary
==========================================
[Functions](#functions)
------------------------
[json\_map(kv)](#json_map/1)
Encodes a JSON map from a compile-time keyword.
[json\_map\_take(map, take)](#json_map_take/2)
Encodes a JSON map from a variable containing a map and a compile-time
list of keys.
[Link to this section](#functions)
Functions
=============================================
[Link to this macro](#json_map/1 "Link to this macro")
json\_map(kv)
=============
[View Source](https://github.com/michalmuskala/jason/blob/v1.4.1/lib/helpers.ex#L32 "View Source")
(macro)
Encodes a JSON map from a compile-time keyword.
Encodes the keys at compile time and strives to create as flat iodata
structure as possible to achieve maximum efficiency. Does encoding
right at the call site, but returns an `%Jason.Fragment{}` struct
that needs to be passed to one of the "main" encoding functions -
for example [`Jason.encode/2`](Jason.html#encode/2) for final encoding into JSON - this
makes it completely transparent for most uses.
Only allows keys that do not require escaping in any of the supported
encoding modes. This means only ASCII characters from the range
0x1F..0x7F excluding '\', '/' and '"' are allowed - this also excludes
all control characters like newlines.
Preserves the order of the keys.
[example](#json_map/1-example)
Example
----------------------------------------
```
iex> fragment = json\_map(foo: 1, bar: 2)
iex> Jason.encode!(fragment)
"{\"foo\":1,\"bar\":2}"
```
[Link to this macro](#json_map_take/2 "Link to this macro")
json\_map\_take(map, take)
==========================
[View Source](https://github.com/michalmuskala/jason/blob/v1.4.1/lib/helpers.ex#L70 "View Source")
(macro)
Encodes a JSON map from a variable containing a map and a compile-time
list of keys.
It is equivalent to calling [`Map.take/2`](https://hexdocs.pm/elixir/Map.html#take/2) before encoding. Otherwise works
similar to `json_map/2`.
[example](#json_map_take/2-example)
Example
---------------------------------------------
```
iex> map = %{a: 1, b: 2, c: 3}
iex> fragment = json\_map\_take(map, [:c, :b])
iex> Jason.encode!(fragment)
"{\"c\":3,\"b\":2}"

Overview
===============================================================================================================================
> Still early in development & subject to change
>
>
`mix phx.gen.solid` exists to generate the boilerplate usually required when
utilizing the SOLID principles, outlined below, in a larger phoenix project.
By default it provides fairly general templates for each of the handlers,
services, finders, and values. However, all of the templates are completely
overrideable.
[currently-supported-generators](#currently-supported-generators)
Currently Supported Generators
--------------------------------------------------------------------------------------------------
* [`Mix.Tasks.Phx.Gen.Solid.Value`](Mix.Tasks.Phx.Gen.Solid.Value.html) - used to generate a value
* `Mix.Tasks.Phx.Gen.Solid.Handler` - TODO
* [`Mix.Tasks.Phx.Gen.Solid.Service`](Mix.Tasks.Phx.Gen.Solid.Service.html) - used to generate C~~R~~UD services
* `Mix.Tasks.Phx.Gen.Solid.Finder` - TODO
[solid-principles](#solid-principles)
SOLID Principles
--------------------------------------------------------
The best way to contain cyclomatic complexity is by employing SOLID principles whenever applicable:
> Single-responsibility principle - A class/module should only have a single responsibility
>
>
> Open-closed principle - Software entities should be open to extension but closed to modification
>
>
> Liskov Substitution principle - Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
>
>
> Interface Segregation principle - Many client-specific interfaces are better than one general-purpose interface.
>
>
> Dependency inversion principle - Abstractions over concretions
>
>
[4-patterns](#4-patterns)
4 Patterns
--------------------------------------
A way to enforce the SOLID principles is by implementing a combination of 4
design patterns and their interactions to guide codebase scalability.
* Handlers
* Services
* Finders
* Values
###
[handlers](#handlers)
Handlers
Handlers are orchestators. They exist only to dispatch and compose. It orders
execution of tasks and/or fetches data to put a response back together.
**Do**
* Organize by business logic, domain, or sub-domain
* Orchestrate high level operations
* Command services, finders, values or other handlers
* Multiple public functions
* Keep controllers thin
* Make it easy to read
* Flow control (if, case, pattern match, etc.)
**Don't**
* Directly create/modify data structures
* Execute any read/write operations
Below is an example of a handler that creates a user, sends a notification, and
fetches some data.
```
defmodule Remoteoss.Handler.Registration do
alias Remoteoss.Accounts.Service.{CreateUser, SendNotification}
alias Remoteoss.Accounts.Finder.SuperHeroName
def setup\_user(name) do
with {:ok, user} <- CreateUser.call(name),
:ok <- SendNotification.call(user),
super\_hero\_details <- SuperHeroName.find(name) do
{user, super\_hero\_details}
else
error ->
error
end
end
end
```
###
[services](#services)
Services
Services are the execution arm. Services execute actions, write data, invoke
third party services, etc.
**Do**
* Organize by Application Logic
* Reusable across Handlers and other Services
* Commands services, finders and values
* Focuses on achieving one single goal
* Exposes a single public function: `call`
* Create/modify data structures
* Execute and take actions
**Don't**
* Use a service to achieve multiple goals
* Call Handlers
* If too big you need to break it into smaller services or your service is
actually a handler
Below is an example of a service that creates a user.
```
defmodule Remoteoss.Accounts.Service.CreateUser do
alias Remoteoss.Accounts
alias Remoteoss.Service.ActivityLog
require Logger
def call(name) do
with {:ok, user} <- Accounts.create\_user(%{name: name}),
:ok <- ActivityLog.call(:create\_user) do
{:ok, user}
else
{:error, %Ecto.Changeset{} = changeset} ->
{:error, {:invalid\_params, changeset.errors}}
error ->
error
end
end
end
```
###
[finders](#finders)
Finders
Finders fetch data, they don't mutate nor write, only read and present.
Non-complex database queries may also exist in Phoenix Contexts. A query can be
considered complex when their are several conditions for filtering, ordering,
and/or pagination. Rule of thumb is when passing a params or opts Map variable
to the function, a Finder is more appropriate.
**Do**
* Organized by Application Logic
* Reusable across Handlers and Services
* Focuses on achieving one single goal
* Exposes a single public function: `find`
* Read data structure
* Uses Values to return complex data
* Finders only read and look up data
**Don't**
* Call any services
* Create/modify data structures
Below is an example of a finder that finds a user.
```
defmodule Remoteoss.Accounts.Finder.UserWithName do
alias Remoteoss.Accounts
def find(name) when is\_binary(name) do
case Accounts.get\_user\_by\_name(name) do
nil -> {:error, :not\_found}
user -> {:ok, user}
end
end
def find(\_), do: {:error, :invalid\_name}
end
```
###
[values](#values)
Values
Values allow us to compose data structures such as responses,
intermediate objects, etc.
**Do**
* Organize by Application Logic
* Reusable across Handlers, Services, and Finders
* Focuses on composing a data structure
* Exposes a single public function: `build`
* Use composition to build through simple logic
* Only returns a [`List`](https://hexdocs.pm/elixir/List.html) or a [`Map`](https://hexdocs.pm/elixir/Map.html)
**Don't**
* Call any Services, Handlers or Finders
Below is an example of a value that builds a user object to be used in a JSON
response. Note this utilizes the helper functions generated with
[`Mix.Tasks.Phx.Gen.Solid.Value`](Mix.Tasks.Phx.Gen.Solid.Value.html).
```
defmodule Remoteoss.Accounts.Value.User do
alias Remoteoss.Value
@valid\_fields [:id, :name]
def build(user, valid\_fields \\ @valid\_fields)
def build(nil, \_), do: nil
def build(user, valid\_fields) do
user
|> Value.init()
|> Value.only(valid\_fields)
end
end
```

=========================================================================================================================================================================================
Generates Value logic for a resource.
```
mix phx.gen.solid.value Accounts User users id name age
```
The first argument is the context module followed by the schema module and its
plural name.
This creates a new Value in `MyApp.Accounts.Value.User`. By default the
allowed fields for this value will be the arguments you passed into the
generator, in this case, `@valid_fields [:id, :slug, :name]`.
**Options**
* `--helpers` - This will generate the Value helpers context in `MyApp.Value`.
Module name can be overridden by `--value-context`.
* `--value-context MODULE` - This will be the name used for the helpers alias
and/or helper modue name when generated. Defaults to `MyApp.Value`.
The generated Value relies on a few helper functions also generated by this
task. By default it will be placed in your projects context folder.
For more information about the generated Value, see the [Overview](overview.html).
