# Garrett Zsh Theme for Prezto
# Created with modified code by Chauncey Garrett
# (ver.2013.05.21.15.17.46)
#
# A prompt full of information when you need it and absent when you don't.
#
# This prompt has the following features:
# - change prompt color when UID is root
# - change host color when on SSH
# - display full or truncated hostname on SSH
# - determine the number of background jobs
# - report the present working directory
# - report return codes
# - report local time
# - report the terminal line number
# - report git status, git remote status, git prompt info and git SHA information
# - indicate vi-mode
# - growl notifications for commands taking longer than x time
#
# Features may be disabled and rearranged as desired by using the corresponding tokens.

This prompt is configurable via styles:
Context: :prompt:garrett
Colors (red green yellow blue magenta cyan white grey):
color_user | The color for user@host. Defaults to 'green'
root_color | The color for the hostname for root. Defaults to 'red'
color_prompt | The color for everything else. Defaults to ''
Path (path type - possible values):
ratio - use COLUMNS/ratio to clip the path. Default.
fixed - use a fixed maximum lenght.
subdir - clip by number of subdirectories.
full - show the full path
Path length styles:
ratio | the ratio for the 'ratio' path style, funnily enough. Defaults to 6.
length | the maximum length for the 'fixed' path style. Defaults to 20.
subdir | the number of subdirs to show for the 'subdir' path style. Defaults to 3.
You can set styles in the current terminal to test things out, values will be updated.
