   5# Distributed under the GNU General Public License, version 2.0.
   6#
   7# The contained completion routines provide support for completing:
   8#
   9#    *) local and remote branch names
  10#    *) local and remote tag names
  11#    *) .git/remotes file names
  12#    *) git 'subcommands'
  13#    *) git email aliases for git-send-email
  14#    *) tree paths within 'ref:path/to/file' expressions
  15#    *) file paths within current working directory and index
  16#    *) common --long-options
  17#
  18# To use these routines:
  19#
  20#    1) Copy this file to somewhere (e.g. ~/.git-completion.bash).
  21#    2) Add the following line to your .bashrc/.zshrc:
  22#        source ~/.git-completion.bash
  23#    3) Consider changing your PS1 to also show the current branch,
  24#       see git-prompt.sh for details.
  25#
  26# If you use complex aliases of form '!f() { ... }; f', you can use the null
  27# command ':' as the first command in the function body to declare the desired
  28# completion style.  For example '!f() { : git commit ; ... }; f' will
  29# tell the completion to use commit completion.  This also works with aliases
  30# of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".

  87# This function can be used to access a tokenized list of words
  88# on the command line:
  89#
  90#       __git_reassemble_comp_words_by_ref '=:'
  91#       if test "${words_[cword_-1]}" = -w
  92#       then
  93#               ...
  94#       fi
  95#
  96# The argument should be a collection of characters from the list of
  97# word completion separators (COMP_WORDBREAKS) to treat as ordinary
  98# characters.
  99#
 100# This is roughly equivalent to going back in time and setting
 101# COMP_WORDBREAKS to exclude those characters.  The intent is to
 102# make option types like --date=<type> and <rev>:<path> easy to
 103# recognize by treating each shell word as a single token.
 104#
 105# It is best not to set COMP_WORDBREAKS directly because the value is
 106# shared with other completion scripts.  By the time the completion
 107# function gets called, COMP_WORDS has already been populated so local
 108# changes to COMP_WORDBREAKS have no effect.
 109#
 110# Output: words_, cword_, cur_.
