# bash/zsh git prompt support
#
# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
# Distributed under the GNU General Public License, version 2.0.
#
# This script allows you to see repository status in your prompt.
#
# To enable:
#
# 1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
# 2) Add the following line to your .bashrc/.zshrc:
# source ~/.git-prompt.sh
# 3a) Change your PS1 to call __git_ps1 as
# command-substitution:
# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
# the optional argument will be used as format string.
# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
# with two parameters, <pre> and <post>, which are strings
# you would put in $PS1 before and after the status string
# generated by the git-prompt machinery. e.g.
# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
# will show username, at-sign, host, colon, cwd, then
# various status string, followed by dollar and SP, as
# your prompt.
# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
# will show username, pipe, then various status string,
# followed by colon, cwd, dollar and SP, as your prompt.
# Optionally, you can supply a third argument with a printf
# format string to finetune the output of the branch status
#
# The repository status will be displayed only if you are currently in a
# git repository. The %s token is the placeholder for the shown status.
#
# The prompt status always includes the current branch name.
#
# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
# unstaged (*) and staged (+) changes will be shown next to the branch
# name. You can configure this per-repository with the
# bash.showDirtyState variable, which defaults to true once
# GIT_PS1_SHOWDIRTYSTATE is enabled.
#
# You can also see if currently something is stashed, by setting
# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
# then a '$' will be shown next to the branch name.
#
# If you would like to see if there're untracked files, then you can set
# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
# files, then a '%' will be shown next to the branch name. You can
# configure this per-repository with the bash.showUntrackedFiles
# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
# enabled.
#
# If you would like to see the difference between HEAD and its upstream,
# set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates you are behind, ">"
# indicates you are ahead, "<>" indicates you have diverged and "="
# indicates that there is no difference. You can further control
# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
# of values:
#
# verbose show number of commits ahead/behind (+/-) upstream
# legacy don't use the '--count' option available in recent
# versions of git-rev-list
# git always compare HEAD to @{upstream}
# svn always compare HEAD to your SVN upstream
#
# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
# find one, or @{upstream} otherwise. Once you have set
# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
# setting the bash.showUpstream config variable.
#
# If you would like to see more information about the identity of
# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
# to one of these values:
#
# contains relative to newer annotated tag (v1.6.3.2~35)
# branch relative to newer tag or branch (master~4)
# describe relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
# default exactly matching tag
#
# If you would like a colored hint about the current dirty state, set
# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
# the colored output of "git status -sb" and are available only when
# using __git_ps1 for PROMPT_COMMAND or precmd.
# stores the divergence from upstream in $p
# used by GIT_PS1_SHOWUPSTREAM
