# Based on 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://gist.github.com/1595572).
#
# 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'
SEGMENT_SEPARATOR=''
ONLINE='%{%F{green}%}◉'
OFFLINE='%{%F{red}%}⦿'
# Begin a segment
# Takes two arguments, background and foreground. Both can be omitted,
# rendering default background/foreground.
prompt_segment() {
local bg fg
[[ -n $1 ]] && bg="%K{$1}" || bg="%k"
[[ -n $2 ]] && fg="%F{$2}" || fg="%f"
if [[ $CURRENT_BG != 'NONE' && $1 != $CURRENT_BG ]]; then
echo -n " %{$bg%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR%{$fg%} "
else
echo -n "%{$bg%}%{$fg%} "
fi
CURRENT_BG=$1
[[ -n $3 ]] && echo -n $3
}
# End the prompt, closing any open segments
prompt_end() {

echo -n " %{%k%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR"
else
echo -n "%{%k%}"
fi
echo -n "%{%f%}"
CURRENT_BG=''
}
### Prompt components
# Each component will draw itself, and hide itself if no information needs to be shown
# Context: user@hostname (who am I and where am I)
prompt_context() {
local user=`whoami`
if [[ "$user" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
