6# This script allows you to see repository status in your prompt.
7#
8# To enable:
9#
10# 1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
11# 2) Add the following line to your .bashrc/.zshrc/.profile:
12# . ~/.git-prompt.sh # dot path/to/this-file
13# 3a) Change your PS1 to call __git_ps1 as
14# command-substitution:
15# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
16# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
17# the optional argument will be used as format string.
18# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
19# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
20# with two parameters, <pre> and <post>, which are strings
21# you would put in $PS1 before and after the status string
22# generated by the git-prompt machinery. e.g.
23# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
24# will show username, at-sign, host, colon, cwd, then
25# various status string, followed by dollar and SP, as
26# your prompt.
27# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
28# will show username, pipe, then various status string,
29# followed by colon, cwd, dollar and SP, as your prompt.
30# Optionally, you can supply a third argument with a printf
31# format string to finetune the output of the branch status
32#
33# See notes below about compatibility with other shells.
34#
35# The repository status will be displayed only if you are currently in a
36# git repository. The %s token is the placeholder for the shown status.
37#
38# The prompt status always includes the current branch name.
39#
40# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
41# unstaged (*) and staged (+) changes will be shown next to the branch
42# name. You can configure this per-repository with the
43# bash.showDirtyState variable, which defaults to true once
44# GIT_PS1_SHOWDIRTYSTATE is enabled.
45#
46# You can also see if currently something is stashed, by setting
47# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
48# then a '$' will be shown next to the branch name.
49#
50# If you would like to see if there're untracked files, then you can set
51# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
52# files, then a '%' will be shown next to the branch name. You can
53# configure this per-repository with the bash.showUntrackedFiles
54# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
55# enabled.
56#
57# If you would like to see the difference between HEAD and its upstream,
58# set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates you are behind, ">"
59# indicates you are ahead, "<>" indicates you have diverged and "="
60# indicates that there is no difference. You can further control
61# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
62# of values:
63#
64# verbose show number of commits ahead/behind (+/-) upstream
65# name if verbose, then also show the upstream abbrev name
66# legacy don't use the '--count' option available in recent
67# versions of git-rev-list
68# git always compare HEAD to @{upstream}
69# svn always compare HEAD to your SVN upstream
70#
71# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
72# find one, or @{upstream} otherwise. Once you have set
73# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
74# setting the bash.showUpstream config variable.
75#
76# You can change the separator between the branch name and the above
77# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
78# is SP.
79#
80# When there is an in-progress operation such as a merge, rebase,
81# revert, cherry-pick, or bisect, the prompt will include information
82# related to the operation, often in the form "|<OPERATION-NAME>".
83#
84# When the repository has a sparse-checkout, a notification of the form
85# "|SPARSE" will be included in the prompt. This can be shortened to a
86# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted
87# by setting GIT_PS1_OMITSPARSESTATE.
88#
89# If you would like to see a notification on the prompt when there are
90# unresolved conflicts, set GIT_PS1_SHOWCONFLICTSTATE to "yes". The
91# prompt will include "|CONFLICT".
92#
93# If you would like to see more information about the identity of
94# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
95# to one of these values:
96#
97# contains relative to newer annotated tag (v1.6.3.2~35)
98# branch relative to newer tag or branch (master~4)
99# describe relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
100# tag relative to any older tag (v1.6.3.1-13-gdd42c2f)
101# default exactly matching tag
102#
103# If you would like a colored hint about the current dirty state, set
104# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
105# the colored output of "git status -sb".
106#
107# If you would like __git_ps1 to do nothing in the case when the current
108# directory is set up to be ignored by git, then set
109# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
110# repository level by setting bash.hideIfPwdIgnored to "false".
111#
112# Compatibility with other shells (beyond bash/zsh):
113#
114# We require posix-ish shell plus "local" support, which is most
115# shells (even pdksh), but excluding ksh93 (because no "local").
116#
117# Prompt integration might differ between shells, but the gist is
118# to load it once on shell init with '. path/to/git-prompt.sh',
119# set GIT_PS1* vars once as needed, and either place $(__git_ps1..)
120# inside PS1 once (0/1 args), or, before each prompt is displayed,
121# call __git_ps1 (2/3 args) which sets PS1 with the status embedded.
122#
123# Many shells support the 1st method of command substitution,
124# though some might need to first enable cmd substitution in PS1.
125#
126# When using colors, each escape sequence is wrapped between byte
127# values 1 and 2 (control chars SOH, STX, respectively), which are
128# invisible at the output, but for bash/readline they mark 0-width
129# strings (SGR color sequences) when calculating the on-screen
130# prompt width, to maintain correct input editing at the prompt.
131#
132# To replace or disable the 0-width markers, set GIT_PS1_COLOR_PRE
133# and GIT_PS1_COLOR_POST to other markers, or empty (nul) to not
134# use markers. For instance, some shells support '\[' and '\]' as
135# start/end markers in PS1 - when invoking __git_ps1 with 3/4 args,
136# but it may or may not work in command substitution mode. YMMV.
137#
138# If the shell doesn't support 0-width markers and editing behaves
139# incorrectly when using colors in __git_ps1, then, other than
140# disabling color, it might be solved using multi-line prompt,
141# where the git status is not at the last line, e.g.:
142# PS1='\n\w \u@\h$(__git_ps1 " (%s)")\n\$ '
143
144# check whether printf supports -v
145__git_printf_supports_v=
