How to contribute#
Contributions are always welcome. Everything ranging from small extensions of the documentation to implementing new features is appreciated. Of course, the bigger the change the more it is necessary to reach out to us in advance for an discussion. You can post an issue or contact janosg via email.
To get acquainted with the code base, you can also check out our issue tracker for some immediate and clearly defined tasks.
Assuming you have settled on contributing a small fix to the project, please read the Styleguide on the next page before you continue.
Next, fork the repository. This will create a copy of the repository where you have write access. Your fix will be implemented in your copy. After that, you will start a pull request (PR) which means a proposal to merge your changes into the project. If you plan to become a regular contributor we can give you push access to unprotected branches, which makes the process more convenient for you.
Clone the repository to your disk. Set up the project environment with conda and the and install your local version of estimagic in editable mode. The commands for this are (in a terminal in the root of your local estimagic repo):
conda env create -f environment.yml
conda activate estimagic
pip install -e .
Implement the fix or new feature.
We validate contributions in three ways. First, we have a test suite to check the implementation of respy. Second, we correct for stylistic errors in code and documentation using linters. Third, we test whether the documentation builds successfully.
You can run all checks with
This will run the complete test suite. To run only a subset of the suite you can use the environments,
sphinx, with the
-eflag of tox.
Correct any errors displayed in the terminal.
To correct stylistic errors, you can also install the linters as a pre-commit with
$ pre-commit install
Then, all the linters are executed before each commit and the commit is aborted if one of the check fails. You can also manually run the linters with
$ pre-commit run -a
If the tests pass, push your changes to your repository. Go to the Github page of your fork. A banner will be displayed asking you whether you would like to create a PR. Follow the link and the instructions of the PR template. Fill out the PR form to inform everyone else on what you are trying to accomplish and how you did it.
The PR also starts a complete run of the test suite on a continuous integration server. The status of the tests is shown in the PR. Reiterate on your changes until the tests pass on the remote machine.
Ask one of the main contributors to review your changes. Include their remarks in your changes.
The final PR will be merged by one of the main contributors.
