# powerlevel9k Theme
# https://github.com/bhilburn/powerlevel9k
#
# This theme was inspired by agnoster's Theme:
# https://gist.github.com/3712874
#
# The `vcs_info` hooks in this file are from Tom Upton:
# https://github.com/tupton/dotfiles/blob/master/zsh/zshrc
#
# In order for this theme to render correctly, you will need a Powerline-patched font:
# https://github.com/Lokaltog/powerline-fonts
#
### Segment drawing
# A few utility functions to make it easy and re-usable to draw segmented prompts
# The `CURRENT_BG` variable is used to remember what the last BG color used was
# when building the left-hand prompt. Because the RPROMPT is created from
# right-left but reads the opposite, this isn't necessary for the other side.
CURRENT_BG='NONE'
# These characters require the Powerline fonts to work properly. If see boxes or
# bizarre characters below, your fonts are not correctly installed.
LEFT_SEGMENT_SEPARATOR=''
RIGHT_SEGMENT_SEPARATOR=''
VCS_UNSTAGED_ICON='●'
VCS_STAGED_ICON='✚'
