Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.
You can contribute in many ways:
Types of Contributions¶
Report Bugs and Submit Feedback¶
The best way to report bugs of send feedback is to open an issue at https://github.com/pyfar/sofar/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.
sofar could always use more documentation, whether as part of the official sofar docs, in docstrings, or even on the web in blog posts, articles, and such.
Ready to contribute? Here’s how to set up sofar for local development.
Fork the sofar repo on GitHub.
Clone your fork locally and cd into the sofar directory:
$ git clone --recursive https://github.com/pyfar/sofar.git $ cd sofar/
Note that some graphical Git interfaces can not do the recursive clone. If the folder sofar/sofa_conventions is empty try
$ git submodule update –init
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 sofar python $ conda activate sofar $ conda install pip $ pip install -e . $ pip install -r requirements_dev.txt
Create a branch for local development. Indicate the intention of your branch in its respective name (i.e. feature/branch-name or bugfix/branch-name):
$ git checkout -b name-of-your-bugfix-or-feature
Now you can make your changes locally.
When you’re done making changes, check that your changes pass flake8 and the tests:
$ flake8 sofar tests $ pytest
flake8 test must pass without any warnings for ./sofar and ./tests using the default or a stricter configuration. Flake8 ignores E123/E133, E226 and E241/E242 by default. If necessary adjust the your flake8 and linting configuration in your IDE accordingly.
Commit your changes and push your branch to GitHub:
$ git add . $ git commit -m "Your detailed description of your changes." $ git push origin name-of-your-bugfix-or-feature
Submit a pull request through the GitHub website.
Pull Request Guidelines¶
Before you submit a pull request, check that it meets these guidelines:
The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring.
The pull request should work for Python 3.7 and 3.8. Check https://travis-ci.com/pyfar/sofar/pull_requests and make sure that the tests pass for all supported Python versions.
Sofar uses test-driven development based on three steps and continuous integration to test and monitor the code. In the following, you’ll find a guideline. Note: these instructions are not generally applicable outside of sofar.
The main tool used for testing is pytest.
All tests are located in the tests/ folder.
Make sure that all important parts of sofar are covered by the tests. This can be checked using coverage (see below).
In case of sofar, mainly state verification is applied in the tests. This means that the outcome of a function is compared to a desired value (
assert ...). For more information, it is refered to Martin Fowler’s article.
Pytest provides several, sophisticated functionalities which could reduce the effort of implementing tests.
Similar tests executing the same code with different variables can be parametrized.
Feel free to add more recommendations on useful pytest functionalities here. Consider, that a trade-off between easy implemention and good readability of the tests needs to be found.
You can create an html report on the test coverage by calling
$ pytest –cov=. –cov-report=html
Writing the Documentation¶
Sofar follows the numpy style guide for the docstring. A docstring has to consist at least of
A short and/or extended summary,
the Parameters section, and
the Returns section
Optional fields that are often used are
Here are a few tips to make things run smoothly
Use the tags
:py:class:to reference sofar functions, modules, and classes: For example
:py:func:`~sofar.write_sofa`for a link that displays only the function name.
Code snippets and values as well as external modules, classes, functions are marked by double ticks `` to appear in mono spaced font, e.g.,
Parameters, returns, and attributes are marked by single ticks ` to appear as emphasized text, e.g., unit.
.. [#]to get automatically numbered footnotes.
Do not use footnotes in the short summary. Only use footnotes in the extended summary if there is a short summary. Otherwise, it messes with the auto-footnotes.
See the Sphinx homepage for more information.
Building the Documentation¶
You can build the documentation of your branch using Sphinx by executing the make script inside the docs folder.
$ cd docs/ $ make html
After Sphinx finishes you can open the generated html using any browser
Note that some warnings are only shown the first time you build the documentation. To show the warnings again use
$ make clean
before building the documentation.
To update the submodule containing the conventions and verification rules run
$ git submodule update –init –recursive $ git submodule update –recursive –remote
and then commit the changes
A reminder for the maintainers on how to deploy.
Commit all changes to develop
Update HISTORY.rst in develop
Check if new contributors should be added to AUTHORS.rst
Merge develop into main
Switch to main and run:
$ bumpversion patch --verbose # possible: major / minor / patch
Bumpversion will update all version strings, create and commit tags by default
$ git push –follow-tags
Continuous integration will then deploy to PyPI if tests pass.
Merge main back into develop
