Theia is a young open-source project with a modular architecture. One of the goals is to make sure that we can customize and enhance any Theia application through extensions. So while the main Theia repository contains some common functionality for IDE-like applications, like a file system or a navigator view, most functionality doesn't necessarily need to be put into the core repository but can be developed separately.
In the following some of the typical ways of contribution are described.
It's totally fine to ask questions by opening an issue in the Theia GitHub repository. We will close it once it's answered and tag it with the 'question' label. Please check if the question has been asked before there or on Stack Overflow.
If you have found a bug, you should first check if it has already been filed and maybe even fixed. If you find an existing unresolved issue, please add your case. If you could not find an existing bug report, please file a new one. In any case, please add all information you can share and that will help to reproduce and solve the problem.
You may want to see a feature or have an idea. You can file a request and we can discuss it. If such a feature request already exists, please add a comment or some other form of feedback to indicate you are interested too. Also in this case any concrete use case scenario is appreciated to understand the motivation behind it.
Before you get started investing significant time in something you want to get merged and maintained as part of Theia, you should talk with the team through an issue. Simply choose the issue you would want to work on, and tell everyone that you are willing to do so and how you would approach it. The team will be happy to guide you and give feedback.
We follow the coding guidelines described here.
Before your contribution can be accepted by the project team contributors must electronically sign the Eclipse Contributor Agreement (ECA).
Commits that are provided by non-committers must have a Signed-off-by field in the footer indicating that the author is aware of the terms by which the contribution has been provided to the project. The non-committer must additionally have an Eclipse Foundation account and must have a signed Eclipse Contributor Agreement (ECA) on file.
For more information, please see the Eclipse Committer Handbook: https://www.eclipse.org/projects/handbook/#resources-commit
The sign-off is a simple line at the end of the explanation for the patch. Your signature certifies that you wrote the patch or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
