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#

sequence could always use more documentation, whether as part of the official sequence 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/sequence-dev/sequence/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 sequence for local development.

  1. Fork the sequence repo on GitHub.

  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/sequence.git

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

    $ conda create -n sequence
$ conda activate sequence
$ pip install -e .

  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 sequence tests
$ pytest

    To get flake8 and pytest, just condat install them into your environment.

  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 3.6 and 3.7. Check https://travis-ci.org/sequence-dev/sequence/pull_requests and make sure that the tests pass for all supported Python versions.

Tips#

To run a subset of tests:

$ pytest tests.test_sequence

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:

$ git tag <version>
$ git push
$ git push --tags

conda-forge will see the new tag, and set up a pull request with the new version. Once the pull request is merged, sequence will be deployed to the conda-forge channel.
