Every little bit helps, and credit will always be given. You can contribute in many ways: Types of Contributions ---------------------- Report Bugs ~~~~~~~~~~~ Report bugs at https://github.com/WoLpH/numpy-stl/issues. If you are reporting a bug, please include: * Your operating system name and version. * Any details about your local setup that might be helpful in troubleshooting. * Detailed steps to reproduce the bug. Fix Bugs ~~~~~~~~ Look through the GitHub issues for bugs. Anything tagged with "bug" is open to whoever wants to implement it. Implement Features ~~~~~~~~~~~~~~~~~~ Look through the GitHub issues for features. Anything tagged with "feature" is open to whoever wants to implement it. Write Documentation ~~~~~~~~~~~~~~~~~~~ Python Progressbar could always use more documentation, whether as part of the official Python Progressbar 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/WoLpH/numpy-stl/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 `numpy-stl` for local development. 1. Fork the `numpy-stl` repo on GitHub. 2. Clone your fork locally:: $ git clone --branch develop git@github.com:your_name_here/numpy-stl.git numpy_stl 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 numpy_stl $ cd numpy_stl/ $ pip install -e . 4. Create a branch for local development with `git-flow-avh`_:: $ git-flow feature start name-of-your-bugfix-or-feature Or without git-flow: $ git checkout -b feature/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 --ignore=W391 stl tests $ py.test $ tox To get flake8 and tox, just pip install them into your virtualenv using the requirements file. $ pip install -r tests/requirements.txt 6. Commit your changes and push your branch to GitHub with `git-flow-avh`_:: $ git add . $ git commit -m "Your detailed description of your changes." $ git-flow feature publish Or without git-flow: $ git add . $ git commit -m "Your detailed description of your changes." $ git push -u origin feature/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 2.7, 3.3, 3.4 and 3.5. Check https://travis-ci.org/WoLpH/numpy-stl/pull_requests and make sure that the tests pass for all supported Python versions.
