PyMotorCAD

PyAnsys Python PyPI GH-CI Codecov MIT Black

This Python package provides the core Python RPC-JSON interface for Motor-CAD.

Install the package

PyMotorCAD has two installation modes: user and developer.

Install in user mode

Before installing PyMotorCAD in user mode, run this command to esure that you have the latest version of pip:

python -m pip install -U pip

Then, run this command to install PyMotorCAD:

python -m pip install ansys-motorcad-core

Install in developer mode

Installing PyMotorCAD in developer mode allows you to modify the source and enhance it.

Note

Before contributing to this project, ensure that you are familiar with all guidelines in the PyAnsys Developer's Guide.

To install in developer mode, complete these steps:

  1. Clone the pymotorcad repository with this command:

    git clone https://github.com/ansys/pymotorcad
  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 and documentation, testing, and CI tools with this command:

    python -m pip install -U pip tox
  4. Install the project in editable mode with this command:

    python -m pip install --editable ansys-motorcad-core
  5. Verify your development installation with this command:

    tox

Testing

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

While Makefile has rules, tox has environments. In fact, tox creates its own virtual environment to guarantee the project's integrity by isolating anything being tested.

tox commands

Here are commands for running various checks in the tox environment:

  • 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 the documentation-building process.

Raw testing

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

Style checks

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

To build documentation, you can run the usual rules provided in the Sphinx Makefile with a command like this:

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

However, the recommended way of checking documentation integrity is to use this tox command:

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

For more information, see the Documentation page in the PyMotorCAD documentation.

Distribution

If you would like to create either source or wheel files, run the following code to install the building requirements and execute the build module:

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