   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 #    *) file paths within current working directory and index
  17 #    *) common --long-options
  18 #
  19 # To use these routines:
  20 #
  21 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
  22 #    2) Add the following line to your .bashrc/.zshrc:
  23 #        source ~/.git-completion.sh
  24 #    3) Consider changing your PS1 to also show the current branch,
  25 #       see git-prompt.sh for details.

  97 # This function can be used to access a tokenized list of words
  98 # on the command line:

 100 #       __git_reassemble_comp_words_by_ref '=:'
 101 #       if test "${words_[cword_-1]}" = -w

 106 # The argument should be a collection of characters from the list of
 107 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 108 # characters.
 109 #
 110 # This is roughly equivalent to going back in time and setting
 111 # COMP_WORDBREAKS to exclude those characters.  The intent is to
 112 # make option types like --date=<type> and <rev>:<path> easy to
 113 # recognize by treating each shell word as a single token.
 114 #
 115 # It is best not to set COMP_WORDBREAKS directly because the value is
 116 # shared with other completion scripts.  By the time the completion
 117 # function gets called, COMP_WORDS has already been populated so local
 118 # changes to COMP_WORDBREAKS have no effect.
