# 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). | ||
# | ||
# In addition, I recommend the | ||
# [Solarized theme](https://github.com/altercation/solarized/) and, if you're | ||
# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app - | ||
# it has significantly better color fidelity. | ||
# | ||
# # 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' | ||
LEFT_SEGMENT_SEPARATOR='' | ||
RIGHT_SEGMENT_SEPARATOR='' | ||
|
||
# Begin a left prompt segment | ||
# Takes two arguments, background and foreground. Both can be omitted, | ||
# rendering default background/foreground. | ||
left_prompt_segment() { | ||
local bg fg | ||
[[ -n $1 ]] && bg="%K{$1}" || bg="%k" | ||
[[ -n $2 ]] && fg="%F{$2}" || fg="%f" | ||
