Pull Requests and Contributing to XlsxWriter

Ad a Missing option in documentation. And I'm missing a easy way to report that. All patches and pull requests are welcome but must start with an issue tracker.

Getting Started

Pull requests and new feature proposals must start with an issue tracker. This serves as the focal point for the design discussion.
Describe what you plan to do. If there are API changes or additions add some pseudo-code to demonstrate them.
Fork the repository.
Run all the tests to make sure the current code work on your system using make test.
Create a feature branch for your new feature.

Writing Tests

This is the most important step. XlsxWriter has over 1000 tests and a 2:1 test to code ratio. Patches and pull requests for anything other than minor fixes or typos will not be merged without tests.

Use the existing tests in XlsxWriter/xlsxwriter/test/ as examples.

Ideally, new features should be accompanied by tests that compare XlsxWriter output against actual Excel 2007 files. See the XlsxWriter/xlsxwriter/test/comparison test files for examples. If you don't have access to Excel 2007 I can help you create input files for test cases.

Tests should use the standard unittest Python module.

Code Style

Follow the general style of the surrounding code and format it to the PEP8 coding standards.

Tests should conform to PEP8 but can ignore E501 for long lines to allow the inclusion of Excel XML in tests.

There is a make target that will verify the source and test files using flake8:

make test_flake8

Running tests

As a minimum, tests should be run using Python 3.6+.

make test
# or
pytest

I use pythonbrew and Tox to test with a variety of Python versions. See the Makefile for example test targets. A tox.ini file is already configured.

When you push your changes they will also be tested using GitHub Actions.

Documentation

If your feature requires it then write some RST documentation in Sphinx format or add to the existing documentation.

The docs, in dev/docs/source can be built in Html format using:

make docs

Example programs

If applicable add an example program to the examples directory.

Copyright and License

Copyright remains with the original author. Do not include additional copyright claims or Licensing requirements. GitHub and the git repository will record your contribution an it will be acknowledged in the Changes file.

Submitting the Pull Request

If your change involves several incremental git commits then rebase or squash them onto another branch so that the Pull Request is a single commit or a small number of logical commits.

Push your changes to GitHub and submit the Pull Request with a hash link to the to the Issue tracker that was opened above.
