# Fish completions for the OpenZFS zfs command
# Possible enhancements:
# - add a test to propose iSCSI and Trusted Extensions completions only when such system is present;
# - Illumos man pages suggests that it does not support nbmand nor atime mount option, so these properties should be proposed only when available
# - generally, propose properties only when the current OS and ZFS versions support them;
# - for the promote command, propose only eligible filesystems;
# - for the rollback command, propose only the most recent snapshot for each dataset, as it will not accept an intermediary snapshot;
# - for the release command, complete with existing tags;
# - for the diff command, complete the destination dataset of the diff;
# - for the program command, complete the script to be executed
# - for commands accepting several arguments of different types, propose arguments in the right order: for get, once the ZFS parameters have been given, only propose datasets
