| **Thank you for thinking about contributing something to this Python | ||
| implementation on Graal!** | ||
|
|
||
| ## First things first | ||
|
|
||
| You will need to sign the [Oracle Contributor | ||
| Agreement](http://www.graalvm.org/community/contributors/) for us to be able to | ||
| merge your work. | ||
|
|
||
| Please also take some time to review our [code of | ||
| conduct](http://www.graalvm.org/community/conduct/) for contributors. | ||
|
|
||
| ## How to contribute? | ||
|
|
||
| If you want to make a contribution, it's best to open an issue first about the | ||
| area you would like to offer your help with. This implementation is in an early | ||
| state and it will make more sense to work on some areas than others, so before | ||
| you sink work into a pull request that we won't be able to accept, please talk | ||
| to us :) | ||
|
|
||
| To get started with development on Python, first make sure you can build at | ||
| least the _truffle_ project in the [Graal](https://github.com/oracle/graal) | ||
| repository with our build tool [mx](https://github.com/graalvm/mx), as well as | ||
| [Sulong](https://github.com/graalvm/sulong). | ||
|
|
||
| Once you can build those projects, clone this repository and run | ||
|
|
||
| $ mx build | ||
| $ mx python -c "print(42)" | ||
|
|
||
| If this prints "42", then everything went fine and you just built and ran | ||
| Python. Note that you don't need GraalVM for this, but then you'll only run | ||
| interpreted, which won't give very good performance (but that might be fine for | ||
| development). | ||
|
|
||
| When you make your changes, you can test them with `mx python`. Additionally, | ||
| there are various "gates" that we use on our CI system to check any code that | ||
| goes in. You can run all of these gates using `mx python-gate` or just some by | ||
| using `mx python-gate --tags [TAG]`. Three interesting tags to run that cover | ||
| most things are: | ||
|
|
||
| - `python-unittest` - Run the unittests written in Python, including those for the C extension API | ||
| - `python-graalvm` - Build a minimal GraalVM bundle with Python only and a native launcher | ||
| - `python-license` - Check that all files have the correct copyright headers applied to them |
