Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation

elm-fluent could always use more documentation, whether as part of the official elm-fluent docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/elm-fluent/elm-fluent/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 elm_fluent for local development.

  1. Fork the elm-fluent repo on GitHub.

  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/elm-fluent.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 elm_fluent
    $ cd elm-fluent/
    $ python setup.py develop
    $ pip install -r requirements_dev.txt
    

    We also need Elm and some other tools installed. If you don’t already have it installed and available on your path, you can use nodeenv to first create a nodejs virtualenv:

    $ nodeenv --python-virtualenv
    

    Reload the virtualenv for changes to take affect:

    $ deactivate
    $ workon elm_fluent
    

    And then install things into it:

    $ npm install -g elm@0.18 elm-test@0.18 elm-github-install
    
  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, including testing other Python versions with tox:

    $ flake8 elm_fluent tests
    $ py.test
    $ tox
    

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

    A fast test run:

    $ py.test -k-slow
    

    See py.test docs for more collection options

    Show the browser for the end to end tests:

    $ TEST_SHOW_BROWSER=1 py.test
    
  6. 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
    
  7. Submit a pull request through the GitHub website.

Pull Request Guidelines

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

  1. The pull request should include tests.
  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.
  3. The pull request should work for Python 3.4, 3.5 and 3.6, and for PyPy. Check https://travis-ci.org/elm-fluent/elm-fluent/pull_requests and make sure that the tests pass for all supported Python versions.

Deploying

A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in HISTORY.rst). Then run:

$ bumpversion patch # possible: major / minor / patch
$ git push
$ git push --tags

Travis will then deploy to PyPI if tests pass.
