Write Documentation

DRAGONS Tools could always use more documentation, whether as part of the official DRAGONS Tools docs or in docstrings.

Submit Feedback

The best way to send feedback is to file an issue at https://bitbucket.org/dragons-astro/dragons/issues.

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 :)

Get Started!

Ready to contribute? Here’s how to set up dragons for local development.

  1. Fork the dragons repo on BitBucket.

  2. Clone your fork locally:

    $ git clone git@bitbucket.org:your_name_here/dragons.git

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

    $ mkvirtualenv dragons
$ cd dragons/
$ pip install -e .
$ mv regrid.so dragons/munge

  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

5. When you’re done making changes, check that your changes pass flake8 and the tests:

$ flake8 dragons tests
$ python setup.py test

To get flake8, just pip install them into your virtualenv.

  1. Commit your changes and push your branch to BitBucket:

    $ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

  2. Submit a pull request through the BitBucket website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests (unless it’s a reader for simulation/model output - such tests will be added at a later date).
  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.

Tips

To run a subset of tests:

$ python -m unittest tests.test_dragons
