grunt plugin

This plugin adds completions for grunt.

To use it, add grunt to the plugins array of your .zshrc file:

plugins=(... grunt)

Enable caching

If you want to use the cache, set the following in your .zshrc:

zstyle ':completion:*' use-cache yes

Show grunt file path: zsh zstyle ':completion::complete:grunt::options:' show_grunt_path yes
Cache expiration days (default: 7): zsh zstyle ':completion::complete:grunt::options:' expire 1
Not update options cache if target gruntfile is changed. zsh zstyle ':completion::complete:grunt::options:' no_update_options yes

Note that if you change the zstyle settings, you should delete the cache file and restart zsh.

$ rm ~/.zcompcache/grunt
$ exec zsh
