`Rougail`'s library description
=================================

Rougail is a configuration management library that allows you to load variables in a simple and convenient way.

In the following examples, we will use a specific configuration of Rougail.


.. FIXME: You will find all the configuration options in doc:`configuration`
   find a document with all the configuration options

To load the configuration you must import the `RougailConfig` class and set the `main_structural_directories` values:

.. code-block:: python

    from rougail import RougailConfig

    RougailConfig['main_structural_directories'] = ['dict']

Let's convert a our first structural file
-----------------------------------------

As a reminder, a :term:`structure file` is a set of instructions that will allow us to create :term:`families <family>` and :term:`variables <variable>`.

Let's start by creating a simple structure file.

Here is a first :file:`dict/00-base.yml` structure file:

.. code-block:: yaml

    %YAML 1.2
    ---
    version: 1.1

    my_variable: my_value  # my variable
    ...

Then, let's create the :term:`Tiramisu` objects via the following script:

.. code-block:: python
    :caption: the `script.py` file content

    from rougail import Rougail, RougailConfig

    RougailConfig['main_structural_directories'] = ['dict']
    rougail = Rougail()
    config = rougail.run()
    print(config.value.get())

.. demo:: Let's execute `script.py`:

    .. code-block:: bash

        $ python3 script.py
        {'rougail.my_variable': 'my_value'}

The operator role
--------------------

The :term:`operator` role corresponds to the :term:`tiramisu` settings:

.. image:: ../images/tiramisu_get_set.png

.. index:: questionary

But instead of coding in the end user developer way, the opterator will prefer using the Rougail CLI interface:

.. image:: ../images/QuestionaryChoice.png


The Rougail CLI can output a rather complete view of the dataset:

.. image:: ../images/UserDataOutput.png
