# https://github.com/roryokane/z-fish/blob/master/z.fish
# maintains a jump-list of the directories you actually use
#
# INSTALL:
# * put something like this in your config.fish:
# source /path/to/z.fish
# * cd around for a while to build up the db
# * PROFIT!!
#
# USE:
# * z foo # cd to most frecent dir matching foo
# * z foo bar # cd to most frecent dir matching foo and bar
# * z -r foo # cd to highest ranked dir matching foo
# * z -t foo # cd to most recently accessed dir matching foo
# * z -l foo # list matches instead of cd
# * z -c foo # restrict matches to subdirs of $PWD
