Contributions and Licensing Agreement Template

Hi all, I'd like to contribute <feature X|bugfix Y|docs|something else> to PyWPS.  I confirm that my contributions to PyWPS will be compatible with the PyWPS license guidelines at the time of contribution.


Code, tests, documentation, wiki and issue tracking are all managed on GitHub. Make sure you have a GitHub account.

Code Overview

  • the PyWPS wiki documents an overview of the codebase [TODO]


  • documentation is managed in docs/, in reStructuredText format
  • Sphinx is used to generate the documentation
  • See the reStructuredText Primer on rST markup and syntax


The PyWPS issue tracker is the place to report bugs or request enhancements. To submit a bug be sure to specify the PyWPS version you are using, the appropriate component, a description of how to reproduce the bug, as well as the Python version and the platform.

Forking PyWPS

Contributions are most easily managed via GitHub pull requests. Fork PyWPS into your own GitHub repository to be able to commit your work and submit pull requests.


GitHub Commit Guidelines

  • enhancements and bug fixes should be identified with a GitHub issue
  • commits should be granular enough for other developers to understand the nature / implications of the change(s)
  • for trivial commits that do not need Travis CI to run, include [ci skip] as part of the commit message
  • non-trivial Git commits shall be associated with a GitHub issue. As documentation can always be improved, tickets need not be opened for improving the docs
  • Git commits shall include a description of changes
  • Git commits shall include the GitHub issue number (i.e. #1234) in the Git commit log message
  • all enhancements or bug fixes must successfully pass all OGC CITE tests before they are committed
  • all enhancements or bug fixes must successfully pass all tests before they are committed
  • enhancements which can be demonstrated from the PyWPS tests should be accompanied by example WPS request XML or KVP

Coding Guidelines

  • PyWPS instead of pywps, pyWPS, Pywps, PYWPS
  • always code with PEP 8 conventions
  • always run source code through flake8
  • for exceptions which make their way to OGC ows:ExceptionReport XML, always specify the appropriate locator and code parameters

Submitting a Pull Request

This section will guide you through steps of working on PyWPS. This section assumes you have forked PyWPS into your own GitHub repository. Note that master is the main development branch in PyWPS. for stable releases and managed exclusively by the PyWPS team.

# setup a virtualenv
virtualenv mypywps && cd mypywps
. ./bin/activate

# clone the repository locally
git clone
cd pywps
pip install -e . && pip install -r requirements.txt

# add the main PyWPS development branch to keep up to date with upstream changes
git remote add upstream
git pull upstream master

# create a local branch off master
# The name of the branch should include the issue number if it exists
git branch issue-72
git checkout issue-72

# make code/doc changes
git commit -am 'fix xyz (#72)'
git push origin issue-72

Your changes are now visible on your PyWPS repository on GitHub. You are now ready to create a pull request. A member of the PyWPS team will review the pull request and provide feedback / suggestions if required. If changes are required, make them against the same branch and push as per above (all changes to the branch in the pull request apply).

The pull request will then be merged by the PyWPS team. You can then delete your local branch (on GitHub), and then update your own repository to ensure your PyWPS repository is up to date with PyWPS master:

git checkout master
git pull upstream master
