This is a short guide for potential FourierFlows.jl contributors.
We follow the ColPrac guide for collaborative practices. New contributors should make sure to read that guide.
Tackle an existing issue.
Improve documentation, docstrings, or comments if you found something is hard to use.
Implement a new feature (e.g., a new diagnostic into a module).
If you're interested in working on something, let us know by commenting on an existing issue or by opening a new issue. This is to make sure no one else is working on the same issue and so we can help and guide you in case there is anything you need to know beforehand.
- Each pull request should consist of a logical collection of changes. You can include multiple bug fixes in a single pull request, but they should be related. For unrelated changes, please submit multiple pull requests.
- Do not commit changes to files that are irrelevant to your feature or bugfix (e.g.,
- Be willing to accept criticism and work on improving your code; we don't want to break other users' code, so care must be taken not to introduce bugs. We discuss pull requests and keep working on them until we believe we've done a good job.
- Be aware that the pull request review process is not immediate, and is generally proportional to the size of the pull request.
The easiest way to get involved is to report issues you encounter when using FourierFlows.jl or by requesting something you think is missing.
- Head over to the issues page.
- Search to see if your issue already exists or has even been solved previously.
- If you indeed have a new issue or request, click the "New Issue" button.
- Please be as specific as possible. Include the version of the code you were using, as well as what operating system you are running. The output of Julia's
] statusis helpful to include. If possible, include complete, minimal example code that reproduces the problem.
- Install Julia on your system.
- Install git on your system if it is not already there (install XCode command line tools on a Mac or git bash on Windows).
- Login to your GitHub account and make a fork of the FourierFlows.jl repository by clicking the "Fork" button.
- Clone your fork of the FourierFlows.jl repository (in terminal on Mac/Linux or git shell/ GUI on Windows) in the location you'd like to keep it.
git clone https://github.com/your-user-name/FourierFlows.jl.git
- Navigate to that folder in the terminal or in Anaconda Prompt if you're on Windows.
- Connect your repository to the upstream (main project).
git remote add FourierFlows https://github.com/FourierFlows/FourierFlows.jl.git
- Create the development environment by opening Julia via
julia --projectthen typing in
] instantiate. This will install all the dependencies in the
- You can test to make sure FourierFlows.jl works by typing in
] test. This will run all the tests (this can take a while). In an ideal world you should run the tests on a machine with a GPU capability but if that's not a possibility that is available to you then don't worry – simply comment in a PR that you didn't test on GPU.
Your development environment is now ready!
Changes and contributions should be made via GitHub pull requests against the
When you're done making changes, commit the changes you made. Chris Beams has written a guide on how to write good commit messages.
When you think your changes are ready to be merged into the main repository, push to your fork and submit a pull request.
Working on your first Pull Request? You can learn how from this free video series How to Contribute to an Open Source Project on GitHub, Aaron Meurer's tutorial on the git workflow, or the guide “How to Contribute to Open Source".
All PRs that introduce new features or new modules should be accompanied with appropriate docstrings and documentation. Writing documentation strings is really important to make sure others use your functionality properly. Didn't write new functions? That's fine, but be sure that the documentation for the code you touched is still in great shape. It is not uncommon to find some strange wording or clarification that you can take care of while you are here.
We encourage using unicode characters when writing docstrings, e.g., use
α instead of
\alpha. This makes the rendering of the docstrings in the Documentation and in the Julia REPL's
help?> mode as similar as possible.
You can preview how the Documentation will look like after merging by building the documentation locally. To do that, from the main directory of your local repository call
julia --project=docs/ -e 'using Pkg; Pkg.develop(PackageSpec(path=pwd())); Pkg.instantiate()'
julia --project=docs/ docs/make.jl
and then open
docs/build/index.html in your favorite browser.
