# Eriner's Theme - fork of agnoster
|
|
# A Powerline-inspired theme for ZSH
|
|
#
|
|
# In order for this theme to render correctly, you will need a font with
|
|
# powerline symbols. A simple way to add the powerline symbols is to follow the
|
|
# instructions here:
|
|
# https://simplyian.com/2014/03/28/using-powerline-symbols-with-your-current-font/
|
|
#
|
|
# 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.
|
|
#
|
|
# Requires the `git-info` zmodule to be included in the .zimrc file.
