How it works

MacVim registers the mvim url handler to open files and directly jump to lines and columns.
We can use this to convert stacktraces reported by RSpec into clickable mvim-links.

MacVim

Requires at least MacVim 7.3. To change how MacVim opens external files go to
'Preferences' > 'Open files from applications' and select 'in the current window' and from
the dropdown menu select 'and set the arglist' to open the file in the last active buffer.

iTerm2

Cmd-Click on an mvim-link to open the file.

      file = File.join Dir.pwd, file  # create an absolute path
 
      line = backtrace_split[1]       # line number
      rest = backtrace_split[2..-1]   # the rest
 
      # output.puts cyan("#{long_padding}# #{backtrace_info}")
      output.puts cyan("#{long_padding}# mvim://open?url=file://#{file}&line=#{line} #{rest.join(':')}")

My iTerm opens any file path in mvim (Cmd+click) by default in new buffer. I can't understand why you guys use this strange solution :)

chendo commented

+1 @gorkunov.

I developed iTerm2's Semantic History feature for this very purpose. http://vimeo.com/21872771

You can Cmd+Click any path with or without a line number and it will open it in your text editor of choice.

Configure it by going to Preferences -> Profiles -> Advanced -> Semantic History.

@chendo you just blew my mind. That is an awesome feature.

rubiii commented

wow that's awesome! thanks @chendo

@chendo i just looked at the following line from an rspec test run and thought:

"what if you could click on this line and have iTerm execute the command to run the exact test again?"

rspec ./spec/wasabi/integration/data_exchange_spec.rb:21

i think this would be pretty useful and could be implemented in a pretty generic way
by extending semantic history and making it look at the command in that line.

what do you think?
