   3# bash/zsh completion support for core Git.

   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) Add the following line to your .bashrc/.zshrc:
  22#        source ~/.git-completion.sh
  23#
  24#    3) Consider changing your PS1 to also show the current branch:
  25#         Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
  26#         ZSH:  PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
  27#
  28#       The argument to __git_ps1 will be displayed only if you
  29#       are currently in a git repository.  The %s token will be
  30#       the name of the current branch.
  31#
  32#       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
  33#       value, unstaged (*) and staged (+) changes will be shown next
  34#       to the branch name.  You can configure this per-repository
  35#       with the bash.showDirtyState variable, which defaults to true
  36#       once GIT_PS1_SHOWDIRTYSTATE is enabled.
  37#
  38#       You can also see if currently something is stashed, by setting
  39#       GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
  40#       then a '$' will be shown next to the branch name.
  41#
  42#       If you would like to see if there're untracked files, then you can
  43#       set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
  44#       untracked files, then a '%' will be shown next to the branch name.
  45#
  46#       If you would like to see the difference between HEAD and its
  47#       upstream, set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates
  48#       you are behind, ">" indicates you are ahead, and "<>"
  49#       indicates you have diverged.  You can further control
  50#       behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated
  51#       list of values:
  52#           verbose       show number of commits ahead/behind (+/-) upstream
  53#           legacy        don't use the '--count' option available in recent
  54#                         versions of git-rev-list
  55#           git           always compare HEAD to @{upstream}
  56#           svn           always compare HEAD to your SVN upstream
  57#       By default, __git_ps1 will compare HEAD to your SVN upstream
  58#       if it can find one, or @{upstream} otherwise.  Once you have
  59#       set GIT_PS1_SHOWUPSTREAM, you can override it on a
  60#       per-repository basis by setting the bash.showUpstream config
  61#       variable.

 349# This function can be used to access a tokenized list of words
 350# on the command line:
 351#
 352#       __git_reassemble_comp_words_by_ref '=:'
 353#       if test "${words_[cword_-1]}" = -w
 354#       then
 355#               ...
 356#       fi
 357#
 358# The argument should be a collection of characters from the list of
 359# word completion separators (COMP_WORDBREAKS) to treat as ordinary
 360# characters.
 361#
 362# This is roughly equivalent to going back in time and setting
 363# COMP_WORDBREAKS to exclude those characters.  The intent is to
 364# make option types like --date=<type> and <rev>:<path> easy to
 365# recognize by treating each shell word as a single token.
 366#
 367# It is best not to set COMP_WORDBREAKS directly because the value is
 368# shared with other completion scripts.  By the time the completion
 369# function gets called, COMP_WORDS has already been populated so local
 370# changes to COMP_WORDBREAKS have no effect.
 371#
 372# Output: words_, cword_, cur_.
