Using other rspec formatters

[louim]

Hey @briandunn!

First, a big thanks for putting this gem together. I'd like to know how much work would be required to allow using other rspec formatters? I'm mostly interested about using a formatter that will immediately print failure in the while the specs are still running. Eg: https://github.com/thekompanee/fuubar or https://github.com/grosser/rspec-instafail.

Would it be something possible at all?

Yes, this should totally be possible. There is already an API for implementing Flatware formatters. These are the methods that will be called on your formatter: https://github.com/briandunn/flatware/blob/master/lib/flatware/broadcaster.rb#L6-L13
Here is where the built in RSpec console formatter is instantiated: https://github.com/briandunn/flatware/blob/master/lib/flatware/rspec/cli.rb#L20-L23

Roughly the steps to implement one of those:

1. restore the formatter CLI option.
2. write an adapter from the Flatware events to the RSpec events, similar to https://github.com/briandunn/flatware/blob/master/lib/flatware/rspec/formatters/console.rb.

It may be possible to write a general adapter that make most rspec formatters work. that would be cool.
