# vim:ft=zsh ts=2 sw=2 sts=2 # # agnoster's Theme - https://gist.github.com/3712874 # A Powerline-inspired theme for ZSH # # # README # # In order for this theme to render correctly, you will need a # [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts). # Make sure you have a recent version: the code points that Powerline # uses changed in 2012, and older versions will display incorrectly, # in confusing ways. # # In addition, I recommend the # [Solarized theme](https://github.com/altercation/solarized/) and, if you're # using it on Mac OS X, [iTerm 2](https://iterm2.com/) over Terminal.app - # it has significantly better color fidelity. # # If using with "light" variant of the Solarized color schema, set # SOLARIZED_THEME variable to "light". If you don't specify, we'll assume # you're using the "dark" variant. # # # Goals # # The aim of this theme is to only show you *relevant* information. 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' case ${SOLARIZED_THEME:-dark} in light) CURRENT_FG='white';; *) CURRENT_FG='black';; esac # Special Powerline characters () { local LC_ALL="" LC_CTYPE="en_US.UTF-8" # NOTE: This segment separator character is correct.
