#autoload
# The main loop of the completion code. This is what is called when
# completion is attempted from the command line.
# If you want to complete only set or unset options for the unsetopt
# and setopt builtin, un-comment these lines:
#
# local _set_options _unset_options
#
# _set_options=(${(k)options[(R)on]})
# _unset_options=(${(k)options[(R)off]})
#
# This is needed because completion functions may set options locally
# which makes the output of setopt and unsetopt reflect a different
# state than the global one for which you are completing.
setopt localoptions nullglob rcexpandparam extendedglob
unsetopt markdirs globsubst shwordsplit nounset ksharrays
exec </dev/null # ZLE closes stdin, which can cause errors
# Failed returns from this code are not real errors
