# Progressive theme that displays only relevant information as needed.
|
|
|
# Builds on both sorin and nicoulaj theme.
|
|
|
#
|
|
|
# Features:
|
|
|
# - Multiple verbosity styles:
|
|
|
# - One or multiple lines
|
|
|
# - In minimal style, only shows user@hostname if connected through SSH.
|
|
|
# - toggle with aliases "P 0" ... "P 5"
|
|
|
# - VCS information in the right prompt.
|
|
|
# - Supports both prezto's git-info and zsh's default vcs_info
|
|
|
# - A callback function can decide whether to use the featureful git-info or faster
|
|
|
# vcs_info on a case-by-case basis:
|
|
|
# define prompt_is_git_info_ok and return false when you want to force the faster vcs_info
|
|
|
# - If using the default vcs_info module:
|
|
|
# - Only shows the path on the left prompt by default.
|
|
|
# - Crops the path to a defined length and only shows the path relative to
|
|
|
# the current VCS repository root.
|
|
|
# - Shows if logged in as root or not.
|
|
|
# - Shows number of jobs
|
|
|
# - Shows shell level if greater than 1
|
|
|
# - Colors work with Solarized theme implemented by remapping 8-bit ANSI colors
|
|
|
# - Supports callbacks for customizing style and value of user and hostname:
|
|
|
# prompt_map_user and prompt_map_host are passed in the original values and are expected
|
|
|
# to return: $prompt_info_user and $prompt_info_user_unformatted
|
|
|
# $prompt_info_host and $prompt_info_host_unformatted
|
