Contribute#

Overall guidance on contributing to a PyAnsys library appears in Contributing in the PyAnsys developer’s guide. Ensure that you are thoroughly familiar with this guide before attempting to contribute to Ansys SCADE Git Extensions.

The following contribution information is specific to Ansys SCADE Git Extensions.

Install in developer mode#

Installing Ansys SCADE Git Extensions in developer mode allows you to modify the source and enhance it.

Clone the ansys-scade-git repository:

git clone https://github.com/ansys/scade-git

Access the scade-git directory where the repository has been cloned:
```
cd scade-git
```

Create a clean Python 3.10 environment and activate it:

You should use the interpreter delivered with Ansys SCADE. For example, C:\Program Files\ANSYS Inc\v241\SCADE\contrib\Python310\python.exe.

# Create a virtual environment
python -m venv .venv

# Activate it in Windows CMD environment
.venv\Scripts\activate.bat

# Activate it in Windows Powershell
.venv\Scripts\Activate.ps1

Make sure that you have the latest required build system, documentation, testing, and CI tools:

python -m pip install -U pip     # Upgrading pip
python -m pip install tox        # Installing tox (optional)
python -m pip install .[build]   # for building the wheels
python -m pip install .[tests]   # for testing the package
python -m pip install .[doc]     # for building the documentation

Install the project in editable mode:
```
python -m pip install --editable .
```
Configure the project:
```
python -m ansys.scade.git.register
```
Use tox to verify your development installation:
```
tox
```

Test#

Ansys SCADE Git Extensions uses tox for testing. This tool allows you to automate common development tasks (similar to Makefile), but it is oriented towards Python development.

Use `tox`#

While Makefile has rules, tox has environments. In fact, tox creates its own virtual environment so that anything being tested is isolated from the project to guarantee the project’s integrity.

The following tox commands are provided:

tox -e style: Checks for coding style quality.
tox -e py: Checks for unit tests.
tox -e py-coverage: Checks for unit testing and code coverage.
tox -e doc-html: Checks for the documentation-building process.

Use raw testing#

If required, from the command line, you can call style commands like black, isort, and flake8. You can also call unit testing commands like pytest. However, running these commands does not guarantee that your project is being tested in an isolated environment, which is the reason why tools like tox exist.

Use `pre-commit`#

Ansys SCADE Git Extensions follows the PEP8 standard as outlined in PEP 8 in the PyAnsys developer’s guide and implements style checking using pre-commit.

To ensure your code meets minimum code styling standards, run these commands:

pip install pre-commit
pre-commit run --all-files

You can also install this as a pre-commit hook by running this command:

pre-commit install

This way, it’s not possible for you to push code that fails the style checks:

$ pre-commit install
$ git commit -am "added my cool feature"
Add License Headers......................................................Passed
ruff.....................................................................Passed
codespell................................................................Passed
check for merge conflicts................................................Passed
debug statements (python)................................................Passed
check yaml...............................................................Passed
trim trailing whitespace.................................................Passed

Build documentation#

For building documentation, you can run the usual rules provided in the Sphinx make file. Here are some examples:

#  build and view the doc from the POSIX system
make -C doc/ html && your_browser_name doc/html/index.html

# build and view the doc from a Windows environment
.\doc\make.bat clean
.\doc\make.bat html
start .\doc\_build\html\index.html

However, the recommended way for checking documentation integrity is to use tox:

tox -e doc-html && your_browser_name .tox/doc_out/index.html

Distribute#

If you would like to create either source or wheel files, start by installing the building requirements and then executing the build module:

python -m pip install .[build]
python -m build
python -m twine check dist/*

Post issues#

Use the Ansys SCADE Git Extensions Issues page to submit questions, report bugs, and request new features. When possible, use these templates:

Bug, problem, error: For filing a bug report
Documentation error: For requesting modifications to the documentation
Adding an example: For proposing a new example
New feature: For requesting enhancements to the code

If your issue does not fit into one of these template categories, click the link for opening a blank issue.
