plaster-dynaconf 0.1.0
A plaster plugin to configure pyramid app with Dynaconf
Requires Python: >=3.6

# Plaster Dynaconf

## Introduction

By default, Pyramid use a pasteDeploy ini format file to loads its configuration,

here is a plugin to use [Dynaconf](https://dynaconf.com) instead to configure
your pyramid application.

e.g.

```
pserve dynaconf://settings.yml
```

### Why another Configuration Loader for Pyramid's plaster?

To answer this weustion lets have a look about what is so cool on Dynaconf.
With the creation of Dynaconf the autor(s) have created a tool that handles the
reading of configuration data very well. This is especially true for applications
that are developed to be deployed in different enironments. Most of web applications
are that kind of thing.
In development of such applications you know how the settings should be for
your development environment and everything that is no specific to *your*
env and no secret should be in the source code. But The idea of
[12-factor-apps](https://12factor.net) goes even farther everything what one
knows about the environment types the application will be deployed should be in
the source too and be overridden or extended with secrets in the specific env
with environment varibales.

You can do this with pasteDeploy too, but the need of different files for
different environments is not as convinient as one default settings file
with useful defaults for different environments that can overridden by the
environments. And what environemnt is present is set by the environment and not
by the file.

On my flask driven apps using dynaconf the start up of the application looks
everythere the same `flask run`. 
I wanted to have a similar approach for my pyramid apps.
`pserve dynaconf://settings.yml`

Maybe it could even go as far as `pserve dynaconf://` but I am not sure if
it is worth to do that much implicit especially because since dynaconf3 less
things happen implicit than before.

### When will this be on version 1.x.y?

If I or someone else had time to write some good tests. Vecause this packages
is mainly an integration piece of dynaconf and plaster with the clear
destination to be used with `pserve` for pyramid there are not just unit tests
required. For now it "works for me" applies and I do not want to let this kind of
measurement be the one for version 1.x.y .

## Installation

```
pip install plaster-yaml
```

## Usage

This package registers itself by default for the entrypoint
`'plaster.loader_factory'` so that it can be used in the way described above.
If you wish to be able to do something like
`pserve settings.yml` you have to add a configuration for the  entry point for
`file+yml` to your setup.py or example:
```
setup(
    ...,
    entry_points={
     'paste.app_factory': ['main = <my_app>:main'],
     'plaster.loader_factory': ['file+yml = plaster_yaml:Loader'],
     ...
    },
)
```

You must run `pip install -e .` to finallize the registration.

## Troubleshouting

If you get the following exception:

```
plaster.exceptions.LoaderNotFound: Could not find a matching loader for the scheme "file+yaml", protocol "wsgi".
```

It meast that you did not register the entry point. Read the usage section
for to register it properly.
