Like most # prompts, it will only show git information when in a git working directory. # However, it goes a step further: everything from the current user and # hostname to whether the last call exited with an error to whether background # jobs are running in this shell will all be displayed automatically when # appropriate. ### Segment drawing # A few utility functions to make it easy and re-usable to draw segmented prompts CURRENT_BG='NONE' # Fix odd char on mac if [[ `uname` == 'Darwin' ]]; then SEGMENT_SEPARATOR='\ue0b0' else SEGMENT_SEPARATOR='' fi # Begin a segment # Takes two arguments, background and foreground.
