# Contributions Guidelines
|
|
|
|
## Code formatting
|
|
|
|
Try to follow the existing formatting.
|
|
If there is no existing formatting, you may use `clang-format` with our included `.clang-format` configuration.
|
|
|
|
In general, in order of importance:
|
|
- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
|
|
- Prefer readability over dogma.
|
|
- Keep to the existing formatting.
|
|
- Indent with 4 space unless it's in a submodule.
|
|
- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
|

## Signing your work
|
|
|
|
In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
|
|
|
|
This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
|
|
|
|
```
|
|
<commit message>
|
|
|
|
Signed-off-by: Author name <Author email>
|
|
```
|
|
|
|
By signing off your work, you agree to the terms below:
|
|
|
|
```
|
|
Developer's Certificate of Origin 1.1
|
|
|
|
By making a contribution to this project, I certify that:
|
|
|
|
(a) The contribution was created in whole or in part by me and I
|
|
have the right to submit it under the open source license
|
|
indicated in the file; or
|
|
|
|
(b) The contribution is based upon previous work that, to the best
|
|
of my knowledge, is covered under an appropriate open source
|
|
license and I have the right under that license to submit that
|
|
work with modifications, whether created in whole or in part
|
|
by me, under the same open source license (unless I am
|
|
permitted to submit under a different license), as indicated
|
|
in the file; or
|
|
|
|
(c) The contribution was provided directly to me by some other
|
|
person who certified (a), (b) or (c) and I have not modified
|
|
it.
|
|
|
|
(d) I understand and agree that this project and the contribution
|
|
are public and that a record of the contribution (including all
|
|
personal information I submit with it, including my sign-off) is
|
|
maintained indefinitely and may be redistributed consistent with
|
|
this project or the open source license(s) involved.
|
|
```
|
|
|
|
These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
|
|
|
|
As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.
