Eduardo R. D'Avilacf4cac42013-06-26 00:05:17 -03006# This script allows you to see repository status in your prompt.
Felipe Contrerasaf31a452012-05-22 22:46:40 +02007#
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:
12# source ~/.git-prompt.sh
Junio C Hamanode29a7a2012-12-11 15:04:36 -080013# 3a) Change your PS1 to call __git_ps1 as
Simon Oosthoek1bfc51a2012-10-10 21:31:58 +020014# command-substitution:
15# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
Eduardo R. D'Avilacf4cac42013-06-26 00:05:17 -030016# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
Junio C Hamanode29a7a2012-12-11 15:04:36 -080017# the optional argument will be used as format string.
Junio C Hamano46b04592013-07-01 12:41:55 -070018# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
19# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
SZEDER Gábora6942582013-06-24 02:28:02 +020020# with two parameters, <pre> and <post>, which are strings
21# you would put in $PS1 before and after the status string
22# generated by the git-prompt machinery. e.g.
Ramkumar Ramachandra96786962013-05-17 14:25:48 +053023# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
Eduardo R. D'Avilacf4cac42013-06-26 00:05:17 -030024# will show username, at-sign, host, colon, cwd, then
25# various status string, followed by dollar and SP, as
26# your prompt.
Ramkumar Ramachandra96786962013-05-17 14:25:48 +053027# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
Eduardo R. D'Avilacf4cac42013-06-26 00:05:17 -030028# will show username, pipe, then various status string,
29# followed by colon, cwd, dollar and SP, as your prompt.
Simon Oosthoek126b5962012-12-26 20:15:05 +010030# Optionally, you can supply a third argument with a printf
31# format string to finetune the output of the branch status
Felipe Contrerasaf31a452012-05-22 22:46:40 +020032#
Eduardo R. D'Avilacf4cac42013-06-26 00:05:17 -030033# The repository status will be displayed only if you are currently in a
34# git repository. The %s token is the placeholder for the shown status.
35#
36# The prompt status always includes the current branch name.
Felipe Contrerasaf31a452012-05-22 22:46:40 +020037#
38# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
39# unstaged (*) and staged (+) changes will be shown next to the branch
40# name. You can configure this per-repository with the
41# bash.showDirtyState variable, which defaults to true once
42# GIT_PS1_SHOWDIRTYSTATE is enabled.
43#
44# You can also see if currently something is stashed, by setting
45# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
46# then a '$' will be shown next to the branch name.
47#
48# If you would like to see if there're untracked files, then you can set
49# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
Martin Erik Werner66cb5d42013-02-13 12:01:58 +010050# files, then a '%' will be shown next to the branch name. You can
51# configure this per-repository with the bash.showUntrackedFiles
52# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
53# enabled.

55# If you would like to see the difference between HEAD and its upstream,
56# set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates you are behind, ">"
Jonathan "Duke" Letof9db1922012-09-24 10:41:26 -070057# indicates you are ahead, "<>" indicates you have diverged and "="
58# indicates that there is no difference. You can further control
59# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
60# of values:
Felipe Contrerasaf31a452012-05-22 22:46:40 +020061#
62# verbose show number of commits ahead/behind (+/-) upstream
Julien Carsique1f6806c2013-10-10 16:40:39 +020063# name if verbose, then also show the upstream abbrev name
Felipe Contrerasaf31a452012-05-22 22:46:40 +020064# legacy don't use the '--count' option available in recent
65# versions of git-rev-list
66# git always compare HEAD to @{upstream}
67# svn always compare HEAD to your SVN upstream
68#
Joe Cridgeab7fade2015-06-10 18:19:24 +010069# You can change the separator between the branch name and the above
70# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
71# is SP.

Elijah Newren30b00f02020-06-21 05:21:26 +000073# When there is an in-progress operation such as a merge, rebase,
74# revert, cherry-pick, or bisect, the prompt will include information
75# related to the operation, often in the form "|<OPERATION-NAME>".
76#
Elijah Newrenafda36d2020-06-21 05:21:27 +000077# When the repository has a sparse-checkout, a notification of the form
78# "|SPARSE" will be included in the prompt. This can be shortened to a
79# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted
80# by setting GIT_PS1_OMITSPARSESTATE.
81#
Felipe Contrerasaf31a452012-05-22 22:46:40 +020082# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
83# find one, or @{upstream} otherwise. Once you have set
84# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
85# setting the bash.showUpstream config variable.

369 # subjects the value of PS1 to parameter expansion:
370 #
371 # * bash does unless the promptvars option is disabled

373 # * POSIX shells always do
374 #
375 # If the shell would expand the contents of PS1 when drawing
376 # the prompt, a raw ref name must not be included in PS1.
377 # This protects the user from arbitrary code execution via
378 # specially crafted ref names. For example, a ref named
379 # 'refs/heads/$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)' might cause the
380 # shell to execute 'sudo rm -rf /' when the prompt is drawn.
381 #
382 # Instead, the ref name should be placed in a separate global
383 # variable (in the __git_ps1_* namespace to avoid colliding
384 # with the user's environment) and that variable should be
385 # referenced from PS1. For example:
386 #
387 # __git_ps1_foo=$(do_something_to_get_ref_name)
388 # PS1="...stuff...\${__git_ps1_foo}...stuff..."
389 #
390 # If the shell does not expand the contents of PS1, the raw
391 # ref name must be included in PS1.
392 #
393 # The value of this variable is only relevant when in pcmode.
394 #
395 # Assume that the shell follows the POSIX specification and
396 # expands PS1 unless determined otherwise. (This is more
397 # likely to be correct if the user has a non-bash, non-zsh
398 # shell and safer than the alternative if the assumption is
399 # incorrect.)
