# 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/master/installation.html#patched-fonts
#
# I recommend picking one of these:
#
#     https://github.com/Lokaltog/powerline-fonts
#
# For more advanced awesome, install a nerd fonts patched font (and be sure to
# enable nerd fonts support with `set -g theme_nerd_fonts yes`):
#
#     https://github.com/ryanoasis/nerd-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_git_worktree_support yes
