Our project welcomes external contributions. A good way to familiarize yourself with the codebase and the contribution process is to look for and address issues in the issue tracker.
To contribute code or documentation, please submit a pull request; and please quickly get in touch with us before embarking on a more ambitious contribution.
Note: We appreciate your effort, and want to avoid a situation where a contribution requires extensive rework (by you or by us), sits in backlog for a long time, or cannot be accepted at all!
If you would like to implement a new feature, please raise an issue before sending a pull request so that the proposed feature can be discussed first. This is to avoid putting an effort on a feature that the project developers would not be able to accept into the code base.
If you would like to fix a bug, please raise an issue before sending a pull request so that the bug fix can be tracked properly.
The project maintainers use LGTM (Looks Good To Me) in comments on the code review to indicate acceptance. A change requires LGTMs from two of the maintainers of each component affected.
For a list of the maintainers, please see the maintainers page.
Each source file must include a license header for the Apache Software License 2.0. Using the SPDX format is the simplest approach. For example,
/*
Copyright <holder> All Rights Reserved.
SPDX-License-Identifier: Apache-2.0
*/
We have tried to make it as easy as possible to make contributions. This applies to how we handle the legal aspects of contribution. We use the same approach - the Developer's Certificate of Origin 1.1 (DCO) - that the Linux® Kernel community uses to manage code contributions.
We simply ask that when submitting a patch for review, the developer must include a sign-off statement in the commit message.
Here is an example Signed-off-by line, which indicates that the submitter accepts the DCO:
Signed-off-by: John Doe <[email protected]>
You can include this automatically when you commit a change to your local git repository using the following command:
git commit -s
Please feel free to connect with us on our Slack channel or via email. Note that the projects in this repository are not formal products. As a result, the communication channels are to the maintainers and not to a support staff.
The documentation is a work in progress but should provide a good overview on how to get started with the project.
We follow the LLVM Coding standards in this project. There is a .clang-format file in the master repo clang-format that can be used in conjunction with ClangFormat Tool to automatically format code. For linting,
we use Clang Tidy Linter. This is referenced in the Makefile.
