# Contributing Guidelines

## Security Contact Information

To report a security vulnerability, please use the Tidelift security contact. Tidelift will coordinate the fix and disclosure.

## Questions, Feature Requests, Bug Reports, and Feedback…

…should all be reported on the GitHub Issue Tracker .

## Contributing Code

### Integration with a Another Web Framework…

…should be released as a separate package.

Pull requests adding support for another framework will not be accepted. In order to keep webargs small and easy to maintain, we are not currently adding support for more frameworks. Instead, release your framework integration as a separate package and add it to the Ecosystem page in the GitHub wiki .

### Setting Up for Local Development

1. Fork webargs on GitHub.

    $ git clone https://github.com/marshmallow-code/webargs.git
    $ cd webargs

2. Install development requirements. It is highly recommended that you use a virtualenv. Use the following command to install an editable version of webargs along with its development requirements.

    # After activating your virtualenv
    $ pip install -e '.[dev]'

3. (Optional, but recommended) Install the pre-commit hooks, which will format and lint your git staged files.

    # The pre-commit CLI was installed above
    $ pre-commit install

Note

webargs uses black for code formatting, which is only compatible with Python>=3.6. Therefore, the pre-commit hooks require a minimum Python version of 3.6.

### Git Branch Structure

Webargs abides by the following branching model:

`dev`

  Current development branch. New features should branch off here.

`X.Y-line`

  Maintenance branch for release `X.Y`. Bug fixes should be sent to the most recent release branch.. The maintainer will forward-port the fix to `dev`. Note: exceptions may be made for bug fixes that introduce large code changes.

Always make a new branch for your work, no matter how small. Also, do not put unrelated changes in the same branch or pull request. This makes it more difficult to merge your changes.

### Pull Requests

1. Create a new local branch.

    # For a new feature
    $ git checkout -b name-of-feature dev

    # For a bugfix
    $ git checkout -b fix-something 1.2-line

2. Commit your changes. Write good commit messages.

    $ git commit -m "Detailed commit message"
    $ git push origin name-of-feature

3. Before submitting a pull request, check the following:

- If the pull request adds functionality, it is tested and the docs are updated.

- You’ve added yourself to `AUTHORS.rst`.

4. Submit a pull request to `marshmallow-code:dev` or the appropriate maintenance branch. The CI build must be passing before your pull request is merged.

### Running Tests

To run all tests:

    $ pytest

To run syntax checks:

    $ tox -e lint

(Optional) To run tests in all supported Python versions in their own virtual environments (must have each interpreter installed):

    $ tox

### Documentation

Contributions to the documentation are welcome. Documentation is written in reStructured Text (rST). A quick rST reference can be found here. Builds are powered by Sphinx.

To build the docs in “watch” mode:

    $ tox -e watch-docs

Changes in the `docs/` directory will automatically trigger a rebuild.

### Contributing Examples

Have a usage example you’d like to share? Feel free to add it to the examples directory and send a pull request.
