#
# A prompt with the information you need the moment you need it.
#
# 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 truncated present working directory
#   - Report return codes other than 0
#   - Report local time
#   - Report the terminal line number
#   - Report git status, git remote status, git prompt info and git SHA information
#   - Indicate vi-mode
#   - Notifications for commands taking longer than n time
#
# Features may be disabled and rearranged as desired by using the corresponding tokens.
