# 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/.profile:
#        . ~/.git-prompt.sh   # dot path/to/this-file
#    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
#
#    See notes below about compatibility with other shells.
#
# 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
#
# 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.
#
# You can change the separator between the branch name and the above
# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
# is SP.
#
# When there is an in-progress operation such as a merge, rebase,
# revert, cherry-pick, or bisect, the prompt will include information
# related to the operation, often in the form "|<OPERATION-NAME>".
#
# When the repository has a sparse-checkout, a notification of the form
# "|SPARSE" will be included in the prompt.  This can be shortened to a
# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted
# by setting GIT_PS1_OMITSPARSESTATE.
#
# If you would like to see a notification on the prompt when there are
# unresolved conflicts, set GIT_PS1_SHOWCONFLICTSTATE to "yes". The
# prompt will include "|CONFLICT".
#
# 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".
#
# 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".
#
# Compatibility with other shells (beyond bash/zsh):
#
#    We require posix-ish shell plus "local" support, which is most
#    shells (even pdksh), but excluding ksh93 (because no "local").
#
#    Prompt integration might differ between shells, but the gist is
#    to load it once on shell init with '. path/to/git-prompt.sh',
#    set GIT_PS1* vars once as needed, and either place $(__git_ps1..)
#    inside PS1 once (0/1 args), or, before each prompt is displayed,
#    call __git_ps1 (2/3 args) which sets PS1 with the status embedded.
#
#    Many shells support the 1st method of command substitution,
#    though some might need to first enable cmd substitution in PS1.
#
#    When using colors, each escape sequence is wrapped between byte
#    values 1 and 2 (control chars SOH, STX, respectively), which are
#    invisible at the output, but for bash/readline they mark 0-width
#    strings (SGR color sequences) when calculating the on-screen
#    prompt width, to maintain correct input editing at the prompt.
#
#    To replace or disable the 0-width markers, set GIT_PS1_COLOR_PRE
#    and GIT_PS1_COLOR_POST to other markers, or empty (nul) to not
#    use markers. For instance, some shells support '\[' and '\]' as
#    start/end markers in PS1 - when invoking __git_ps1 with 3/4 args,
#    but it may or may not work in command substitution mode. YMMV.
#
#    If the shell doesn't support 0-width markers and editing behaves
#    incorrectly when using colors in __git_ps1, then, other than
#    disabling color, it might be solved using multi-line prompt,
#    where the git status is not at the last line, e.g.:
#      PS1='\n\w \u@\h$(__git_ps1 " (%s)")\n\$ '

	#
	# 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/.profile:
	# . ~/.git-prompt.sh # dot path/to/this-file
	# 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
	#
	# See notes below about compatibility with other shells.
	#
	# 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
	#
	# 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.
	#
	# You can change the separator between the branch name and the above
	# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
	# is SP.
	#
	# When there is an in-progress operation such as a merge, rebase,
	# revert, cherry-pick, or bisect, the prompt will include information
	# related to the operation, often in the form "\|<OPERATION-NAME>".
	#
	# When the repository has a sparse-checkout, a notification of the form
	# "\|SPARSE" will be included in the prompt. This can be shortened to a
	# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted
	# by setting GIT_PS1_OMITSPARSESTATE.
	#
	# If you would like to see a notification on the prompt when there are
	# unresolved conflicts, set GIT_PS1_SHOWCONFLICTSTATE to "yes". The
	# prompt will include "\|CONFLICT".
	#
	# 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".
	#
	# 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".
	#
	# Compatibility with other shells (beyond bash/zsh):
	#
	# We require posix-ish shell plus "local" support, which is most
	# shells (even pdksh), but excluding ksh93 (because no "local").
	#
	# Prompt integration might differ between shells, but the gist is
	# to load it once on shell init with '. path/to/git-prompt.sh',
	# set GIT_PS1* vars once as needed, and either place $(__git_ps1..)
	# inside PS1 once (0/1 args), or, before each prompt is displayed,
	# call __git_ps1 (2/3 args) which sets PS1 with the status embedded.
	#
	# Many shells support the 1st method of command substitution,
	# though some might need to first enable cmd substitution in PS1.
	#
	# When using colors, each escape sequence is wrapped between byte
	# values 1 and 2 (control chars SOH, STX, respectively), which are
	# invisible at the output, but for bash/readline they mark 0-width
	# strings (SGR color sequences) when calculating the on-screen
	# prompt width, to maintain correct input editing at the prompt.
	#
	# To replace or disable the 0-width markers, set GIT_PS1_COLOR_PRE
	# and GIT_PS1_COLOR_POST to other markers, or empty (nul) to not
	# use markers. For instance, some shells support '\[' and '\]' as
	# start/end markers in PS1 - when invoking __git_ps1 with 3/4 args,
	# but it may or may not work in command substitution mode. YMMV.
	#
	# If the shell doesn't support 0-width markers and editing behaves
	# incorrectly when using colors in __git_ps1, then, other than
	# disabling color, it might be solved using multi-line prompt,
	# where the git status is not at the last line, e.g.:
	# PS1='\n\w \u@\h$(__git_ps1 " (%s)")\n\$ '
