# blecher.at Theme - sped up git support and fixed status, 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://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
|
|

|
|
# Takes two arguments, background and foreground. Both can be omitted,
|
|
# rendering default background/foreground.

|
