Based on my rewrite of the Agnoster theme, uses simpler segment drawing functions and only relies on local variables. Uses git-info module in non-verbose mode, so a repo with only untracked files will not count as dirty (but dirty state is computed faster). Also took the freedom of adding an extra space character after the 'r' for the Ranger segment, and after the dirty indicator for the Git segment. Everything else looks and behaves exactly the same as the original prompt.

# 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.
|
|
#
|
|
# Uses the 'git-info' Zim module.
|
|
|
|

### Prompt components
|
|
# Each component will draw itself, or hide itself if no information needs to be
|
|
# shown.
|
|
|
|
# Status: Was there an error? Am I root? Are there background jobs? Ranger
|
|
# spawned shell? Who and where am I (user@hostname)?
