How to contribute to Marian

Reporting a bug/asking questions

Did you find a bug or want to ask a question? Great!

• Ensure the bug was not already reported or the question was not asked on the github issues or the Google discussion group.
• Open a new issue/question if you're unable to find yours.
• For bugs please provide as much relevant information as possible, and do not forget to attach training/decoding logs and your Marian command.

You are also welcome to request a new feature. Especially if you plan to help us adding it :)

Submitting changes

Whenever possible, please send a Github Pull Request with a clear list of what you've done. Feel free to update CHANGELOG.md file. We will love you forever if you provide unit or regression tests.

Please follow our coding convention (below) and do not forget to test your changes by running unit tests:

cd marian-dev/build
cmake .. -DCOMPILE_TESTS=ON
make test

and regression tests:

cd marian-dev/regression-tests
make install
./run_mrt.sh

Coding conventions

Main code style rules:

• no tabs, 2 whitespaces instead

• no space between control statements and opening brackets
