You can contribute in many ways:

Types of Contributions

Report Bugs or Submit Feedback

To report bugs or send feedback, open an issue at https://github.com/Any2HRTF/mesh2hrtf/issues.

If you are reporting a bug, please include:

  • Your operating system name and version.

  • Any details about your local setup that might be helpful in troubleshooting.

  • Detailed steps to reproduce the bug.

If you are proposing a feature:

  • Explain in detail how it would work.

  • Keep the scope as narrow as possible, to make it easier to implement.

  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Fix Bugs or Implement Features

Look through the GitHub issues for bugs. Anything tagged with “bug” or “enhancement” is open to whoever wants to implement it. It might be good to contact us first, to see if anyone is already working on it.

Write Documentation

Mesh2HRTF could always use more documentation, whether as part of the official Mesh2HRTF docs, in docstrings, or even on the web in blog posts, articles, and such.

Start Contributing

Ready to contribute? Here’s how to set up Mesh2HRTF for local development. Work on the numerical core NumCalc and the Matlab/Octave API can directly be done. Working on the Python API requires a local copy of mesh2hrtf to install the API for local development

  1. Fork the Mesh2HRTF repo on GitHub.

  2. Clone your fork locally and cd into the Mesh2HRTF directory:

    $ git clone https://github.com/Any2HRTF/Mesh2HRTF.git
$ cd Mesh2HRTF

  3. Install your local copy into a virtualenv. Assuming you have Anaconda or Miniconda installed, this is how you set up your fork for local development:

    $ conda create --name mesh2hrtf python
$ conda activate mesh2hrtf
$ pip install -e ".[dev]"

If the installation fails, try to restrict the python version first, e.g., by using.

$ conda create –name mesh2hrtf ‘python<3.13’

The latest work is contained in develop. For bug-fixes, enhancements, and new ideas please create a new branch based on develop.

Testing

Mesh2HRTF uses py pytest for testing. For all tests to work, you must configure your blender path in test/utils.py (variable computer_id and function blender_paths).

  • All tests are ran by

    $ pytest

  • Run a single test with

    $ pytest tests/test_plot.py::test_line_plots

  • Exclude tests (for example the time consuming test of plot) with

    $ pytest -k ‘not plot’

  • Create an html report on the test coverage with

    $ pytest –cov=. –cov-report=html

Submodules

To update the submodules containing the conventions and verification rules run

$ git submodule update –remote mesh2hrtf/Mesh2Input/Meshes/GradingHybrid

Releasing

To release a new Mesh2HRTF version do the following

  • Write the new version to the file VERSION, mesh2input.py, the global __init__.py, and pyproject.toml

  • Commit all changes to develop

  • Update HISTORY.rst (also include new contributors)

  • check if installing the python package works via pip install -e ".[dev]"

  • check if the tests pass

  • check if the documentation is building (configure at https://app.readthedocs.org/projects/mesh2hrtf/)

  • merge develop into main

  • add a tag and release on github

  • merge main into develop
