How to Contribute

We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.

Contributor License Agreement

Contributions to this project must be accompanied by a Contributor License Agreement. You (or your employer) retain the copyright to your contribution; this simply gives us permission to use and redistribute your contributions as part of the project. Head over to to see your current agreements on file or to sign a new one.

You generally only need to submit a CLA once, so if you‘ve already submitted one (even if it was for a different project), you probably don’t need to do it again.

Code reviews

All submissions, including submissions by project members, require review. We use Dawn's Gerrit for this purpose.

Submissions should follow the Tint style guide.

Pushing to Gerrit

Each change requires a Change-Id field in the commit message, which is generated by the Gerrit commit-msg hook.
In a bash terminal, with the current path set to your tint source tree, this can be obtained by running the following:

f=`git rev-parse --git-dir`/hooks/commit-msg ; mkdir -p $(dirname $f) ; curl -Lo $f ; chmod +x $f

If you've already locally committed a change without the Change-Id, running git commit --amend will add the missing Change-Id.

To create a Gerrit change for review, type:

git push origin HEAD:refs/for/main
