# Enable caching:
#
# If you want to use the cache, set the followings in your .zshrc:
#
# zstyle ':completion:*' use-cache yes
#
#
# Settings:
#
# - Show grunt file path:
# zstyle ':completion::complete:grunt::options:' show_grunt_path yes
#
# - Cache expiration days (default: 7):
# zstyle ':completion::complete:grunt::options:' expire 1
#
# - Not update options cache if target gruntfile is changed.
# 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
