# rake-fast
# Fast rake autocompletion plugin for oh-my-zsh
# This script caches the output for later usage and significantly speeds it up.
# It generates a .rake_tasks file in parallel to the Rakefile.
# You'll want to add `.rake_tasks` to your global .git_ignore file:
# https://help.github.com/articles/ignoring-files#global-gitignore
# You can force .rake_tasks to refresh with:
# $ rake_refresh
# This is entirely based on Ullrich Schäfer's work
# (https://github.com/robb/.dotfiles/pull/10/),
# which is inspired by this Ruby on Rails trick from 2006:
# http://weblog.rubyonrails.org/2006/3/9/fast-rake-task-completion-for-zsh/
