# 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. |
|
|
