   5 # Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
   6 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
   7 # Distributed under the GNU General Public License, version 2.0.
   8 #
   9 # The contained completion routines provide support for completing:
  10 #
  11 #    *) local and remote branch names
  12 #    *) local and remote tag names
  13 #    *) .git/remotes file names
  14 #    *) git 'subcommands'
  15 #    *) tree paths within 'ref:path/to/file' expressions
  16 #    *) common --long-options
  17 #
  18 # To use these routines:
  19 #
  20 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
  21 #    2) Added the following line to your .bashrc:
  22 #        source ~/.git-completion.sh
  23 #
  24 #       Or, add the following lines to your .zshrc:
  25 #        autoload bashcompinit
  26 #        bashcompinit
  27 #        source ~/.git-completion.sh
  28 #
  29 #    3) Consider changing your PS1 to also show the current branch:
  30 #        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
  31 #
  32 #       The argument to __git_ps1 will be displayed only if you
  33 #       are currently in a git repository.  The %s token will be
  34 #       the name of the current branch.
  35 #
  36 #       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
  37 #       value, unstaged (*) and staged (+) changes will be shown next
  38 #       to the branch name.  You can configure this per-repository
  39 #       with the bash.showDirtyState variable, which defaults to true
  40 #       once GIT_PS1_SHOWDIRTYSTATE is enabled.
  41 #
  42 #       You can also see if currently something is stashed, by setting
  43 #       GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
  44 #       then a '$' will be shown next to the branch name.
  45 #
  46 #       If you would like to see if there're untracked files, then you can
  47 #       set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
  48 #       untracked files, then a '%' will be shown next to the branch name.
  49 #
  50 #       If you would like to see the difference between HEAD and its
  51 #       upstream, set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates
  52 #       you are behind, ">" indicates you are ahead, and "<>"
  53 #       indicates you have diverged.  You can further control
  54 #       behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated
  55 #       list of values:
  56 #           verbose       show number of commits ahead/behind (+/-) upstream
  57 #           legacy        don't use the '--count' option available in recent
  58 #                         versions of git-rev-list
  59 #           git           always compare HEAD to @{upstream}
  60 #           svn           always compare HEAD to your SVN upstream
  61 #       By default, __git_ps1 will compare HEAD to your SVN upstream
  62 #       if it can find one, or @{upstream} otherwise.  Once you have
  63 #       set GIT_PS1_SHOWUPSTREAM, you can override it on a
  64 #       per-repository basis by setting the bash.showUpstream config
  65 #       variable.
