# ip(8) completion for fish
# The difficulty here is that ip allows abbreviating options, so we need to complete "ip a" like "ip address", but not "ip m" like "ip mroute"
# Also the manpage and even the grammar it accepts is utter shite (options can only be before commands, some things are only in the BNF, others only in the text)
# It also quite likes the word "dev", even though it needs it less than the BNF specifies
