Contributing
So you want to contribute to uMap? Great news 🙌
We've put together this document so you have a brief overview of how things work. You can help on different areas: translation, bug triage, documentation and development.
Translating
uMap is translated to more than 50 languages! The translation is managed through Transifex. You will need an account to get started, and then you'll be able to translate easily.
Bug Triage
You are very welcome to help us triage uMap issues. Don't hesitate to help other users by answering questions, give your point of view in discussions and just report bugs!
Reporting a bug
If you've encountered a bug, don't hesitate to tell us about it. The best way to do this is by opening a ticket on the bug tracker. But please, first, have a look around to see if other users already reported something 😅
Hacking on the code
Following the installation instructions should get you started to hack on the code.
Installing dev dependencies
To be sure to install all the dev dependencies, and have everything working locally.
make develop
JavaScript
For JavaScript, here is the tooling we use:
- Format your code with Prettier
- Be sure to configure your editor to insert new lines at the end of files.
Hack!
You can now do your changes in a specific branch, and when you're ready you can open a pull-request for us to review.
Running tests
Multiple tests suites are in use in the project.
Python unit tests
pytest . --ignore umap/tests/integration
By default, the tests are run in parallel to reduce the time taken to run them. You can run them in serial mode by using the -n1 option.
If you only want to run one test, you can add -k specific-test-name to the command line.
Integration tests
pytest umap/tests/integration
The tests are using Playwright, which spawns a headless browser and runs the tests on it. If the tests are failing, it might be useful to step trough the tests in the browser. This will let you go step by step with a debugger, so you can see what is happening on a real browser.
PWDEBUG=1 pytest --headed -n1 -k specific-test-name
JS tests
make testjs
These tests are located in umap/static/test, and we are currently using a mocha test runner.
All the tests are run when you're creating a pull request, to avoid regressions.
Merging rules
Pull requests need to be accepted by one maintainer of the project. Please be patient, we try to do our best, but it sometimes takes time.
Update the translations
Install needed tools:
apt install gettext transifex-client
Pull the translations from transifex website:
tx pull -f
Then you will need to update binary files with command:
make compilemessages
Done. You can now review and commit modified/added files.
