The Contributor Guide
========================

Welcome to the Python Keycloak contributing guidelines. We are all more than happy to receive
any contributions to the repository and want to thank you in advance for your contributions!
This document outlines the process and the guidelines on how contributions work for this repository.

Setting up the dev environment
-------------------------------

The development environment is mainly up to the developer. Our recommendations are to create a python
virtual environment and install the necessary requirements. Example

.. code-block:: console

    # Install and upgrade pip & poetry
    python -m pip install --upgrade pip poetry

    # Create virtualenv
    python -m poetry env use <PATH_TO_PYTHON_VERSION>

    # install package dependencies including dev dependencies
    python -m poetry install

    # Activate virtualenv
    python -m poetry shell

Running checks and tests
---------------------------

We're utilizing `tox` for most of the testing workflows. However we also have an external dependency on `docker`.
We're using docker to spin up a local keycloak instance which we run our test cases against. This is to avoid
a lot of unnecessary mocking and yet have immediate feedback from the actual Keycloak instance. All of the setup
is done for you with the tox environments, all you need is to have both tox and docker installed
(`tox` is included in the `dev-requirements.txt`).

To run the unit tests, simply run

.. code-block:: console

    tox -e tests

The project is also adhering to strict linting (flake8) and formatting (black + isort). You can always check that
your code changes adhere to the format by running

.. code-block:: console

    tox -e check

If the check fails, you'll see an error message specifying what went wrong. To simplify things, you can also run

.. code-block:: console

    tox -e apply-check

which will apply isort and black formatting for you in the repository. The flake8 problems however need to be resolved
manually by the developer.

Additionally we require that the documentation pages are built without warnings. This check is also run via tox, using
the command

.. code-block:: console

    tox -e docs


The check is also run in the CICD pipelines. We require that the documentation pages built from the code docstrings
do not create visually "bad" pages.

Conventional commits
----------------------

Commits to this project must adhere to the [Conventional Commits
specification](https://www.conventionalcommits.org/en/v1.0.0/) that will allow
us to automate version bumps and changelog entry creation.

After cloning this repository, you must install the pre-commit hook for
conventional commits (this is included in the `dev-requirements.txt`)

.. code-block:: console

    # Create virtualenv
    python -m poetry env use <PATH_TO_PYTHON_VERSION>

    # Activate virtualenv
    python -m poetry shell

    pre-commit install --install-hooks -t pre-commit -t pre-push -t commit-msg

How to contribute
-------------------

1. Fork this repository, develop and test your changes
2. Make sure that your changes do not decrease the test coverage
3. Make sure you're commits follow the conventional commits
4. Submit a pull request

How to release
-------------------

The CICD pipelines are set up for the repository. When a PR is merged, a new version of the library
will be automatically deployed to the PyPi server, meaning you'll be able to see your changes immediately.
