## CLI Usage

```
Usage: ibi [OPTIONS] COMMAND [ARGS]...

  Library and CLI for generating installation instructions from json schema
  and jinja templates.

Options:
  --version   Show the version and exit.
  -h, --help  Show this message and exit.

Commands:
  install  Installs with config and parameters given.
  show     Shows installation instructions for your specified config file...
```

Options are dynamically created with the schema part of the config file.   

> [!TIP]
> Show help for a config file with: `ibi show CONFIG_FILE/FOLDER/GIT_REPO_URL --help`.


## Config

* The config is comprised of a single file `install.cfg`.
* The config has two parts delimited by `------` (6 or more `-`).
* Both parts should be developed in different files for language server support.


### Schema

* The first section of the config is a [json-schema](https://json-schema.org/).
* It can be written in [JSON](https://www.json.org/json-en.html) or to JSON capabilites restricted [YAML](https://yaml.org/).
* When creating a schema use the following schema draft version: https://json-schema.org/draft/2020-12/schema
* `title` are used for pretty print option names.
* `description` is used for the options help message.
* For adding a description and a pretty print name to enum values (for [web-installation-instruction](https://github.com/instructions-d-installation/web-installation-instruction)):
  1. Indent the schema with the key `schema`.
  2. Add `pretty` and `description` keys.
  3. Create lists like `key: Pretty Key`.
* `title` and `description` from within the schema overwrite `pretty` and `description` outside of the schema.
* For the package to set the default os to the running system, name the property `__os__`.

```yaml
schema:
  name: installation-instruction
  type: object
  properties:
    method:
      enum:
        - pipx
        - pip
pretty:
  pipx: Pipx
  pip: Pip
description:
  pipx: Installs python packages into virtual environments.
  pip: Standard python package manager.
```


### Template

* You can have as much whitespace and line breaks as you wish in and inbetween your commands.
* Commands must be seperated by `&&`! (`pip install installation-instruction && pip uninstall installation-instruction`.)
* If you wish to stop the render from within the template you can use the macro `raise`. (`{{ raise("no support!") }}`.) 


### MISC

Please have a look at the [examples](./examples/).
