# 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).
|
|
# Make sure you have a recent version: the code points that Powerline
|
|
# uses changed in 2012, and older versions will display incorrectly,
|
|
# in confusing ways.
|
|
#
|
|
# In addition, I recommend the
|
|
# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
|
|
# using it on Mac OS X, [iTerm 2](https://iterm2.com/) over Terminal.app -
|
|
# it has significantly better color fidelity.
|
|
#
|
|
# If using with "light" variant of the Solarized color schema, set
|
|
# SOLARIZED_THEME variable to "light". If you don't specify, we'll assume
|
|
# you're using the "dark" variant.
|
|
#
|
|
# # 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.
|
|
|

|

# If this is not working for you, you probably have an old version of the
|
|
# Powerline-patched fonts installed. Download and install the new version.
|
|
# Do not submit PRs to change this unless you have reviewed the Powerline code point
|
|
# history and have new information.
|

# This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of
