You can contribute in many ways:
Types of Contributions¶
Report bugs at https://gitlab.aicrowd.com/flatland/flatland/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.
Look through the Repository Issue Tracker for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.
Look through the Repository Issue Tracker for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.
flatland could always use more documentation, whether as part of the official flatland docs, in docstrings, or even on the web in blog posts, articles, and such. A quick reference for writing good docstrings is available at : https://docs.python-guide.org/writing/documentation/#writing-docstrings
The best way to send feedback is to file an issue at https://gitlab.aicrowd.com/flatland/flatland/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 :)
Ready to contribute? Here’s how to set up flatland for local development.
Fork the flatland repo on https://gitlab.aicrowd.com/flatland/flatland .
Clone your fork locally:
$ git clone firstname.lastname@example.org:flatland/flatland.git
Install the software dependencies via Anaconda-3 or Miniconda-3. (This assumes you have Anaconda installed by following the instructions here)
$ conda install -c conda-forge tox-conda $ conda install tox $ tox -v –recreate
This will create a virtual env you can then use.
These steps are performed if you run
from Anaconda prompt.
Create a branch for local development:
$ git checkout -b name-of-your-bugfix-or-feature
Now you can make your changes locally.
When you’re done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:
$ flake8 flatland tests examples benchmarks $ python setup.py test or py.test $ tox
To get flake8 and tox, just pip install them into your virtualenv.
Commit your changes and push your branch to Gitlab:
$ git add . $ git commit -m "Addresses #<issue-number> Your detailed description of your changes." $ git push origin name-of-your-bugfix-or-feature
Submit a merge request through the Gitlab repository website.
Merge Request Guidelines¶
Before you submit a merge request, check that it meets these guidelines:
- The merge request should include tests.
- If the merge 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.
- The merge request should work for Python 3.6, 3.7 and for PyPy. Check https://gitlab.aicrowd.com/flatland/flatland/pipelines and make sure that the tests pass for all supported Python versions.
To run a subset of tests:
$ py.test tests.test_flatland
A reminder for the maintainers on how to deploy. Make sure all your changes are committed . Then run:
$ bumpversion patch # possible: major / minor / patch $ git push $ git push --tags
TODO: Travis will then deploy to PyPI if tests pass. (To be configured properly by Mohanty)
