# bobthefish is a Powerline-style, Git-aware fish theme optimized for awesome.

# You will probably need a Powerline-patched font for this to work:

|
|
# I recommend picking one of these:

|
|
# You can override some default options in your config.fish:
|
|
#
|
|
# set -g theme_display_user yes
|
|
# set -g default_user your_normal_user
|

set -g __bobthefish_current_bg NONE
