Tip: Use diffparser for git DSL

[hubertgrzeskowiak]

I struggled with the raw diffs at first, even writing my own parsers, before I discovered a better way. I thought I'd share a good library that works perfectly with danger-kotlin: https://github.com/thombergs/diffparser

Usage example:

@file:Repository("https://jcenter.bintray.com")
@file:DependsOn("io.reflectoring.diffparser:diffparser:1.4")


danger(args) {
  val diff = UnifiedDiffParser().parse(git.diff!!.byteInputStream())
}

From that object, it's trivial to get changed files, lines added, removed, the different chunks etc. It's a small library, so autocompletion should be all the docs you need, really.

Happy to add this to the README if you reckon it's useful enough, but I didn't want to add anything that may break.
