   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:
  12 #        source ~/.git-prompt.sh
  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 # 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.
  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
  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.
  54 #
  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, ">"
  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:
  61 #
  62 #     verbose       show number of commits ahead/behind (+/-) upstream
  63 #     name          if verbose, then also show the upstream abbrev name
  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 #
  69 # 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.
  72 #
  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 #
  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 #
  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.
  86 #
  87 # If you would like to see more information about the identity of
  88 # commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
  89 # to one of these values:
  90 #
  91 #     contains      relative to newer annotated tag (v1.6.3.2~35)
  92 #     branch        relative to newer tag or branch (master~4)
  93 #     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
  94 #     tag           relative to any older tag (v1.6.3.1-13-gdd42c2f)
  95 #     default       exactly matching tag
  96 #
  97 # If you would like a colored hint about the current dirty state, set
  98 # GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
  99 # the colored output of "git status -sb" and are available only when
 100 # using __git_ps1 for PROMPT_COMMAND or precmd in Bash,
 101 # but always available in Zsh.
 102 #
 103 # If you would like __git_ps1 to do nothing in the case when the current
 104 # directory is set up to be ignored by git, then set
 105 # GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
