We’re excited to collaborate with the community and look forward to the many improvements you can make to OpenTimelineIO!
Contributor License Agreement¶
Before contributing code to OpenTimelineIO, we ask that you sign a Contributor License Agreement (CLA). At the root of the repo you can find the two possible CLAs:
OTIO_CLA_Corporate.pdf: please sign this one for corporate use
OTIO_CLA_Individual.pdf: please sign this one if you’re an individual contributor
Once your CLA is signed, send it to
firstname.lastname@example.org (please make sure to include your github username) and wait for confirmation that we’ve received it. After that, you can submit pull requests.
Please follow the coding convention and style in each file and in each library when adding new files.
Platform Support Policy¶
As recomended by the VFX Platform (see “Support Guidance”), we support the intended calendar year of the release as well as the three prior years.
Here is the workflow we recommend for working on OpenTimelineIO if you intend on contributing changes back:
Post an issue on github to let folks know about the feature or bug that you found, and mention that you intend to work on it. That way, if someone else is working on a similar project, you can collaborate, or you can get early feedback which can sometimes save time.
Use the github website to fork your own private repository.
Clone your fork to your local machine, like this:
git clone https://github.com/you/OpenTimelineIO.git
Add the primary OpenTimelineIO repo as upstream to make it easier to update your remote and local repos with the latest changes:
cd OpenTimelineIO git remote add upstream https://github.com/PixarAnimationStudios/OpenTimelineIO.git
Now you fetch the latest changes from Pixar’s OpenTimelineIO repo like this:
git fetch upstream git merge upstream/main
All the development should happen against the
main branch. We recommend you create a new branch for each feature or fix that you’d like to make and give it a descriptive name so that you can remember it later. You can checkout a new branch and create it simultaneously like this:
git checkout -b mybugfix upstream/main
Now you can work in your branch locally.
Once you are happy with your change, you can verify that the change didn’t cause tests failures by running tests like this:
make test make lint
If all the tests pass and you’d like to send your change in for consideration, push it to your remote repo:
git push origin mybugfix
Now your remote branch will have your
mybugfix branch, which you can now pull request (to OpenTimelineIO’s
main branch) using the github UI.
Please make sure that your pull requests are clean. Use the rebase and squash git facilities as needed to ensure that the pull request is as clean as possible.
