Create autocompletion dropdown for Cucumber paths in Textmate

Ever wanted autocompletion for paths from paths.rb in Cucumber? This card lets you write your steps like this:

CopyWhen I go to path *press tab now* # path is replaced with a list of all known Cucumber paths

This is how you do it

(key shortcuts apply for TextMate2)

1. Open the bundle editor (ctrl + alt +  + B)

2. Create a new Item ( + N), select "Command"

3. Paste this:
   ^
   #!/usr/bin/env ruby -wKU
   require File.join(ENV['TM_SUPPORT_PATH'], 'lib', 'ui.rb')

   cucumber_paths = File.join ENV['TM_PROJECT_DIRECTORY'], 'features', 'support', 'paths.rb'
   if File.exist? cucumber_paths
   lines = []
   File.open(cucumber_paths, 'r').each do |line|
   lines << line.slice(/\s+when /^?([^$]*)$?/[im]?$/, 1) # @param 1: return first matched group
   end
   paths = lines.compact.sort

   TextMate::UI.complete(paths, :extra_chars => " ")
   else
   %x{ "$DIALOG" tooltip --html 'File /features/support/paths.rb not found.' }
   end

Now you only need some more configuration:

• Name the command (e.g. "Cucumber: paths")
• scope selector is text.gherkin.feature
• choose a tab trigger (e.g. "path")
• input: nothing
• output: insert at caret
• caret placement: after output

You're done!
