This provides improved syntax highlighting for rspec. This is pulled from Specky which is a great plugin which just does a little too much for me.
If you don't have a preferred installation method check out vim-plug
By default this syntax is used with all *_spec.rb
files. If you don't
follow this pattern use something like:
autocmd BufNewFile,BufRead *_foo.rb set syntax=rspec
In your ~/.vimrc
