Issues
======

Please report bugs or feature requests by `creating GitHub issues`_.

.. _creating GitHub issues: https://github.com/aas-core-works/aas-core3.0-python/issues

In Code
=======

If you want to contribute in code, pull requests are welcome!

Please do `create a new issue`_ before you dive into coding.
It can well be that we already started working on the feature, or that there are upstream or downstream complexities involved which you might not be aware of.

.. _create a new issue: https://github.com/aas-core-works/aas-core3.0-python/issues

SDK Code Generation
===================

The biggest part of the code has been automatically generated by `aas-core-codegen`_.
It probably makes most sense to change the generator rather than add new functionality.
However, this needs to be decided on a case-by-case basis.

.. _aas-core-codegen: https://github.com/aas-core-works/aas-core-codegen

To re-generate the code, run:

.. code-block::

    python dev_scripts/update_to_aas_core_meta_codegen.py

Test Data
=========

The test data is automatically generated by `aas-core3.0-testgen`_, and copied to this repository on every change.

.. _aas-core3.0-testgen: https://github.com/aas-core-works/aas-core3.0-testgen

Pre-commit Checks
=================

Before you can run pre-commit checks, you need to all the development dependencies.
Run in your virtual environment:

.. code-block::

    pip3 install --editable .
    pip3 install -r requirements-dev.txt

Now you can execute the checks (from the repository root):

.. code-block::

    python continuous_integration/precommit.py

Some of the checks, such as formatting, can be automatically fixed.
If you want a self-healing checks, run:

.. code-block::

    python continuous_integration/precommit.py --overwrite

The pre-commit checks for the development tools are managed separately in
`dev_scripts/continuous_integration_of_dev_scripts`. You can install and run them
in a similar manner from your root directory:

.. code-block::

    pip3 install --editable dev_scripts --group dev_scripts/pyproject.toml:dev
    python dev_scripts/continuous_integration_of_dev_scripts/precommit.py

Pull Requests
=============

**Feature branches**.
We develop using the feature branches, see `this section of the Git book`_.

.. _this section of the Git book: https://git-scm.com/book/en/v2/Git-Branching-Branching-Workflows

If you are a member of the development team, create a feature branch directly within the repository.

Otherwise, if you are a non-member contributor, fork the repository and create the feature branch in your forked repository.
See `this GitHub tutorial`_ for more guidance.

.. _this GitHub tutorial: https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork

**Branch Prefix**.
Please prefix the branch with your Github user name (*e.g.,* ``mristin/Add-some-feature``).

**Continuous Integration**. 
GitHub will run the continuous integration (CI) automatically through GitHub actions.
The CI includes running the tests, inspecting the code, re-building the documentation *etc.*

Commit Messages
===============

The commit messages follow the guidelines from https://chris.beams.io/posts/git-commit:

* Separate subject from body with a blank line,
* Limit the subject line to 50 characters,
* Capitalize the subject line,
