   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 #               ...

  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_.
