[go-nuts] git, golang and continuous integration

I haven't worked with gitlab at all, but it seems like a simple enough problem to solve if you can't find a good existing solution. If you can manage to get gitlab to just run "go build" and other parts of the go tool then you might have the basic functionality youre looking for: if the tool exits with 0 status and no output its a green, otherwise you should report the output to the user and mark it red.

Also, I'm not sure if gofmt notes were just an example, but as far as I know its more common to blindly accept gofmt's suggested style than to cherry pick its suggestions. Usually just running it on each file you're checking in is enough, but running it in diff mode and writing that to the webpage for users to see modifications could also be useful.
