When opening an issue to report a problem, please try and provide a minimal code example that reproduces the issue, and also include details of the operating system, and the Python, Numpy, and Astropy versions you are using.
So you're interested in contributing code to Astropy? Excellent!
Most contributions to Astropy are done via pull requests from GitHub users' forks of the astropy repository. If you're new to this style of development, you'll want to read over our development workflow.
Once you open a pull request (which should be opened against the master
branch, not against any of the other branches), please make sure that you
include the following:
-
Code: the code you are adding, which should follow as much as possible our coding guidelines.
-
Tests: these are usually tests that ensures that code that previously failed now works (regression tests) or tests that cover as much as possible of the new functionality to make sure it doesn't break in future, and also returns consistent results on all platforms (since we run these tests on many platforms/configurations). For more information about how to write tests, see our testing guidelines.
-
Documentation: if you are adding new functionality, be sure to include a description in the main documentation (in
docs/). Again, we have some detailed documentation guidelines to help you out. -
Changelog entry: whether you are fixing a bug or adding new functionality, you should add an entry to the
CHANGES.rstfile that includes if possible the issue number (if you are opening a pull request you may not know this yet, but you can add it once the pull request is open). You do not need to include a changelog entry for fixes to bugs introduced in the developer version and which are not present in the stable releases. In general you do not need to include a changelog entry for minor documentation or test updates. Only user-visible changes (new features/API changes, fixed issues) need to be mentioned. If in doubt ask the core maintainer reviewing your changes.
