ansys-pre-commit-hooks 0.5.2

A Python wrapper to create Ansys-tailored pre-commit hooks

This Ansys repository contains pre-commit hooks for different purposes. The following hooks are currently available:

• add-license-headers: Add missing license headers to files by using REUSE . To use this hook, you must have REUSE implemented in your repository.

• tech-review: Do a technical review of your repository according to Ansys repository requirements

How to install

The following sections provide instructions for installing the ansys-pre-commit-hooks package in two installation modes: user and developer.

For users

Before installing the package, to ensure that you have the latest version of pip, run this command:

python -m pip install -U pip

Then, to install the package, run this command:

python -m pip install ansys-pre-commit-hooks

For developers

Installing the package in developer mode allows you to modify and enhance the source code.

Before contributing to the project, ensure that you are familiar with the PyAnsys Developer’s Guide.

For a developer installation, you must follow these steps:

1. Clone the repository with this command:

   git clone https://github.com/ansys/pre-commit-hooks

2. Create a fresh-clean Python environment and activate it with these commands:

   # Create a virtual environment
   python -m venv .venv
   
   # Activate it in a POSIX system
   source .venv/bin/activate
   
   # Activate it in Windows CMD environment
   .venv\Scripts\activate.bat
   
   # Activate it in Windows Powershell
   .venv\Scripts\Activate.ps1

3. Ensure that you have the latest required build system tools by running this command:

   python -m pip install -U pip flit tox twine

4. Install the project in editable mode by running one of these commands:

   # Install the minimum requirements
   python -m pip install -e .
   
   # Install the minimum + tests requirements
   python -m pip install -e .[tests]
   
   # Install the minimum + doc requirements
   python -m pip install -e .[doc]
   
   # Install all requirements
   python -m pip install -e .[tests,doc]

5. Verify your development installation by running this command:

   tox

How to test it

This project takes advantage of tox. This tool automates common development tasks (similar to Makefile), but it is oriented towards Python development.

Using 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.

These environment 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: Checks for successfully building the documentation.

Raw testing

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

A note on pre-commit

The style checks take advantage of pre-commit. Developers are not forced but encouraged to install this tool by running this command:

python -m pip install pre-commit && pre-commit install

Documentation

For building documentation, you can run the usual rules provided in the Sphinx Makefile with a command that is formatted like this:

make -C doc/ html && your_browser_name doc/html/index.html

However, the recommended way of checking documentation integrity is by running tox with a command that is formatted like this:

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

Distributing

If you would like to create either source or wheel files, install the building requirements and then execute the build module with these commands:

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