# Completion

# %command% generates its own zsh completion, so we cache it instead of
# maintaining a `_%command%` file by hand.
#
# On the first shell after installing this plugin the cache file doesn't exist
# yet, so compinit hasn't bound it. Do that manually here.

# Regenerate the cache in the background so it never blocks shell startup.
# TMPPREFIX puts the temp file next to the destination, which keeps the move
# atomic.
