cf4cac4c | 6 | # This script allows you to see repository status in your prompt. |
af31a456 FC |
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: | |
12 | # source ~/.git-prompt.sh | |
de29a7ac | 13 | # 3a) Change your PS1 to call __git_ps1 as |
1bfc51ac SO |
14 | # command-substitution: |
15 | # Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ ' | |
cf4cac4c | 16 | # ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ ' |
de29a7ac | 17 | # the optional argument will be used as format string. |
46b04591 JH |
18 | # 3b) Alternatively, for a slightly faster prompt, __git_ps1 can |
19 | # be used for PROMPT_COMMAND in Bash or for precmd() in Zsh | |
a6942584 SG |
20 | # with two parameters, <pre> and <post>, which are strings |
21 | # you would put in $PS1 before and after the status string | |
22 | # generated by the git-prompt machinery. e.g. | |
9678696c | 23 | # Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "' |
cf4cac4c EA |
24 | # will show username, at-sign, host, colon, cwd, then |
25 | # various status string, followed by dollar and SP, as | |
26 | # your prompt. | |
9678696c | 27 | # ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" } |
cf4cac4c EA |
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 | |
af31a456 | 32 | # |
cf4cac4c EA |
33 | # 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. | |
af31a456 FC |
37 | # |
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 | |
66cb5d44 MEW |
50 | # 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, ">" | |
f9db1921 JDL |
57 | # 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: | |
af31a456 FC |
61 | # |
62 | # verbose show number of commits ahead/behind (+/-) upstream | |
1f6806cf | 63 | # name if verbose, then also show the upstream abbrev name |
af31a456 FC |
64 | # 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 | # | |

73 | # 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 | # | |
afda36db EN |
77 | # 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 | # | |
af31a456 FC |
82 | # 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. | |
