# Fish completions for the OpenZFS zpool command
# Possible improvements:
# - whenever possible, propose designation of vdevs using their GUID
# - for eligible commands, with arguments of different types, only propose second type completions after the first have been selected; for instance, only propose pool members for offline command
# - this has been written mainly from manpages, which are known to be out-of-sync with the real feature set; some discrepancies have been addressed, but it is highly likely that others still lie
