#compdef salt salt-call salt-cp salt-run salt-key
# The use-cache style is checked in a few places to allow caching minions, modules,
# or the directory salt is installed in.
# you can cache those three with:
# zstyle ':completion:*:salt(|-cp|-call|-run|-key):*' use-cache true
# and/or selectively:
# zstyle ':completion::complete:salt-key:set-option-a-1:'             use-cache false
# zstyle ':completion::complete:salt(|-cp|-call):minions:'            use-cache true
# zstyle ':completion::complete:salt(|-call):modules:'                use-cache true
# zstyle ':completion::complete:salt(|-cp|-call|-run|-key):salt_dir:' use-cache true
#
# cache validation can be controled with the style cache-ttl.
# it expects two arguments: number (days|hours|weeks|months)
# to invalidate the minion cache after four days:
# zstyle ':completion::complete:salt(|-cp|-call):minions:'            cache-ttl 4 days
