# name: bobthefish
#
# bobthefish is a Powerline-style, Git-aware fish theme optimized for awesome.
#
# You will need a Powerline-patched font for this to work:
#
# https://powerline.readthedocs.org/en/latest/fontpatching.html
#
# I recommend picking one of these:
#
# https://github.com/Lokaltog/powerline-fonts
#
# You can override some default prompt options in your config.fish:
#
# set -g theme_display_git no
# set -g theme_display_git_untracked no
# set -g theme_display_git_ahead_verbose yes
# set -g theme_display_vagrant yes
# set -g theme_display_hg yes
# set -g theme_display_virtualenv no
# set -g theme_display_ruby no
# set -g theme_display_user yes
# set -g theme_display_vi yes
# set -g theme_display_vi_hide_mode default
