# 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='⮀' |
|
|
|
# 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() { |
|
if [[ -n $CURRENT_BG ]]; then |
|
echo -n " %{%k%F{$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 "$SSH_CLIENT" ]]; then |
|
prompt_segment black default "%(!.%{%F{yellow}%}.)$user@%m" |
|
fi |
|
} |
|
|
|
# Git: branch/detached head, dirty status |
