Any thoughts about this? I don't want to annoy anyone, but please don't leave a small and focused PR hanging like this 😉

Find these regexes really tough to read, when what we're trying to do is remove the -2 constant. How about:

parts = File.basename(translation.file).split('.')
parts[parts.index(translation.locale)] = locale

path = "#{File.dirname(translation.file)/#{parts.join('.')}"

😁

@1st8 Ha, had that coming 😄

@kaspth Hehe, yeah 😉
Your suggested code is better, indeed. Changed the implementation to use it and extracted it out into a method to make it more readable. Updated the specs as well.

Don't see the point in testing argument positions, sounds like a bag of hurt going forward 😁

I am testing, that the interface defined by Transformation. replace_locale_in_path is used and used correctly. Otherwise I can't be sure, that it is actually used and not being replaced with something inline, which would make my encapsulated tests obsolete.

Coming along nicely 👍
