# 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 any Google project must be accompanied by a Contributor
|
||
|
|
License Agreement. This is not a copyright **assignment**, it simply gives
|
||
|
|
Google permission to use and redistribute your contributions as part of the
|
||
|
|
project.
|
||
|
|
|
||
|
|
* If you are an individual writing original source code and you're sure you
|
||
|
|
own the intellectual property, then you'll need to sign an [individual
|
||
|
|
CLA][].
|
||
|
|
|
||
|
|
* If you work for a company that wants to allow you to contribute your work,
|
||
|
|
then you'll need to sign a [corporate CLA][].
|
||
|
|
|
||
|
|
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.

## Submitting a patch ##
|
||
|
|
|
||
|
|
1. It's generally best to start by opening a new issue describing the bug or
|
||
|
|
feature you're intending to fix. Even if you think it's relatively minor,
|
||
|
|
it's helpful to know what people are working on. Mention in the initial
|
||
|
|
issue that you are planning to work on that bug or feature so that it can
|
||
|
|
be assigned to you.
|
||
|
|
|
||
|
|
1. Follow the normal process of [forking][] the project, and setup a new
|
||
|
|
branch to work in. It's important that each group of changes be done in
|
||
|
|
separate branches in order to ensure that a pull request only includes the
|
||
|
|
commits related to that bug or feature.
|
||
|
|
|
||
|
|
1. Go makes it very simple to ensure properly formatted code, so always run
|
||
|
|
`go fmt` on your code before committing it. You should also run
|
||
|
|
[golint][] over your code. As noted in the [golint readme][], it's not
|
||
|
|
strictly necessary that your code be completely "lint-free", but this will
|
||
|
|
help you find common style issues.
|
||
|
|
|
||
|
|
1. Any significant changes should almost always be accompanied by tests. The
|
||
|
|
project already has good test coverage, so look at some of the existing
|
||
|
|
tests if you're unsure how to go about it. [gocov][] and [gocov-html][]
|
||
|
|
are invaluable tools for seeing which parts of your code aren't being
|
||
|
|
exercised by your tests.
|
||
|
|
|
||
|
|
1. Do your best to have [well-formed commit messages][] for each change.
|
||
|
|
This provides consistency throughout the project, and ensures that commit
|
||
|
|
messages are able to be formatted properly by various git tools.
|
||
|
|
|
||
|
|
1. Finally, push the commits to your fork and submit a [pull request][].
