  9+# agnoster's Theme - https://gist.github.com/3712874
 10+# A Powerline-inspired theme for ZSH
 11+#
 12+# # README
 13+#
 14+# In order for this theme to render correctly, you will need a
 15+# [Powerline-patched font](https://gist.github.com/1595572).
 16+#
 17+# In addition, I recommend the
 18+# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
 19+# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
 20+# it has significantly better color fidelity.
 21+#
 22+# # Goals
 23+#
 24+# The aim of this theme is to only show you *relevant* information. Like most
 25+# prompts, it will only show git information when in a git working directory.
 26+# However, it goes a step further: everything from the current user and
 27+# hostname to whether the last call exited with an error to whether background
 28+# jobs are running in this shell will all be displayed automatically when
 29+# appropriate.
 30+
 31+### Segment drawing
 32+# A few utility functions to make it easy and re-usable to draw segmented prompts
 33+
 34+CURRENT_BG='NONE'
 35+SEGMENT_SEPARATOR='⮀'
 36+
 37+# Begin a segment
 38+# Takes two arguments, background and foreground. Both can be omitted,
 39+# rendering default background/foreground.
