go-golden should support pretty-printed golden files

[vsinha]

Hi jimeh, have you thought about supporting something like json.Indent for updated golden files? It would make them cleaner to read manually, which I think would be a nice thing to have.

Excited about this library!

I believe what is written to golden files is actually outside the scope of the golden package itself, as it just reads/writes byte slices.

But I have been on and off working on a companion package that has assertion helpers for JSON, YAML, and XML. Along with a means for supplying custom marshal/unmarshal functions for any kind of wire format.

I can't promise a timeline, but I want to get it finished "soon", as it would replace and simplify nearly all of my own current uses of the golden package.

That makes sense. I wrote up a helper function for my json-specific application, is this the kind of thing you had in mind?

Just getting started with Go / getting a lay of the land wrt libraries and best practices

Yep, that's roughly the kind of thing I'm doing myself for structs that serialized to JSON/YAML/XML.

And the companion package I'm working on will do that, but lots of flexibility :)
