First off, thanks for taking time to contribute!
The following is a set of guidelines for contributing to Yorc. Feel free to provide feedback about it in an issue or pull request.
Don't be afraid to contribute, if something is unclear then just ask or submit the issue or pull request anyways. The worst that can happen is that you'll be politely asked to change something.
Go 1.11+ is required. The easiest way to install it to follow the official guide
Here is how to install and setup the Yorc project:
sudo apt-get install build-essential git curl
# Or
sudo yum install build-essential git curl
# Install Go
git clone https://github.com/ystia/yorc.git
cd yorc
# Build
make tools
make
Using make
you will automatically generate required code, run unit tests and format code with go fmt
.
You can contribute to the Yorc project in several ways. All of them are welcome.
- Report a documentation issue
- Report a bug
- Report an improvement request
- Propose a PR that fixes one of the above, we will try to tag

Unless explicitly stated, we follow all coding guidelines from the Go community. While some of these standards may seem arbitrary, they somehow seem to result in a solid, consistent codebase.
It is possible that the code base does not currently comply with these guidelines. We are not looking for a massive PR that fixes this, since that goes against the spirit of the guidelines. All new contributions should make a best effort to clean up and make the code base better than they left it. Obviously, apply your best judgement. Remember, the goal here is to make the code base easier for humans to navigate and understand. Always keep that in mind when nudging others to comply.
The rules:
- All code should be formatted with
go fmt
. - All code should pass the default levels of
golint
. - All code should follow the guidelines covered in Effective Go and Go Code Review Comments.
- Comment the code. Tell us the why, the history and the context.
- Document all declarations and methods, even private ones. Declare expectations, caveats and anything else that may be important. If a type gets exported, having the comments already there will ensure it's ready.
- Variable name length should be proportional to its context and no longer.
noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo
. In practice, short methods will have short variable names and globals will have longer names. - No underscores in package names. If you need a compound name, step back, and re-examine why you need a compound name. If you still think you need a compound name, lose the underscore.
- All tests should run with
go test
and outside tooling should not be required. No, we don't need another unit testing framework. Assertion packages are acceptable if they provide real incremental value. - Even though we call these "rules" above, they are actually just guidelines. Since you've read all the rules, you now know that.
If you are having trouble getting into the mood of idiomatic Go, we recommend reading through Effective Go. The Go Blog is also a great resource. Drinking the kool-aid is a lot easier than going thirsty.
