Last night over dinner I had a discussion with Miyagawa about what Devel::Cover could steal from Ruby. He mentioned a Ruby backend which uses Vim signs to show coverage information.

So today I shamelessly stole it and produced a basic version for Devel::Cover.

Devel::Cover has more coverage criteria, so extra work will be required to provide this information, but the report seems useful for now. To use it run

$ cover -report vim

and then in vim:

:so cover_db/coverage.vim

I'd be happy to…
