 #
 # 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
 #     name          if verbose, then also show the upstream abbrev name
 #     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
 #
 # You can change the separator between the branch name and the above
 # state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
 # is SP.
 #
 # 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)
 #     tag           relative to any older 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.
 #
 # If you would like __git_ps1 to do nothing in the case when the current
 # directory is set up to be ignored by git, then set
 # GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
 # repository level by setting bash.hideIfPwdIgnored to "false".

 # Copyright (C) 2006,2007 Shawn O. Pearce <[email protected]>
 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
 # Distributed under the GNU General Public License, version 2.0.
 #
 # The contained completion routines provide support for completing:
 #
 #    *) local and remote branch names
 #    *) local and remote tag names
 #    *) .git/remotes file names
 #    *) git 'subcommands'
 #    *) git email aliases for git-send-email
 #    *) tree paths within 'ref:path/to/file' expressions
 #    *) file paths within current working directory and index
 #    *) common --long-options
 #
 # To use these routines:
 #
 #    1) Copy this file to somewhere (e.g. ~/.git-completion.bash).
 #    2) Add the following line to your .bashrc/.zshrc:
 #        source ~/.git-completion.bash
 #    3) Consider changing your PS1 to also show the current branch,
 #       see git-prompt.sh for details.
 #
 # If you use complex aliases of form '!f() { ... }; f', you can use the null
 # command ':' as the first command in the function body to declare the desired
 # completion style.  For example '!f() { : git commit ; ... }; f' will
 # tell the completion to use commit completion.  This also works with aliases
 # of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".
 #
 # Compatible with bash 3.2.57.
 #
 # You can set the following environment variables to influence the behavior of
 # the completion routines:
 #
 #   GIT_COMPLETION_CHECKOUT_NO_GUESS
 #
 #     When set to "1", do not include "DWIM" suggestions in git-checkout
 #     and git-switch completion (e.g., completing "foo" when "origin/foo"
 #     exists).

	#
	# 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:
	#
