   1 # bash/zsh completion support for core Git.

   3 # Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
   4 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
   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 ; ... '".
  31 #
  32 # If you have a command that is not part of git, but you would still
  33 # like completion, you can use __git_complete:
  34 #
  35 #   __git_complete gl git_log
  36 #
  37 # Or if it's a main command (i.e. git or gitk):
  38 #
  39 #   __git_complete gk gitk
  40 #
  41 # Compatible with bash 3.2.57.
  42 #
  43 # You can set the following environment variables to influence the behavior of
  44 # the completion routines:
  45 #
  46 #   GIT_COMPLETION_CHECKOUT_NO_GUESS
  47 #
  48 #     When set to "1", do not include "DWIM" suggestions in git-checkout
  49 #     and git-switch completion (e.g., completing "foo" when "origin/foo"
  50 #     exists).
  51 #
  52 #   GIT_COMPLETION_SHOW_ALL
  53 #
  54 #     When set to "1" suggest all options, including options which are
  55 #     typically hidden (e.g. '--allow-empty' for 'git commit').

 213 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
 214 # characters.
 215 #
 216 # This is roughly equivalent to going back in time and setting
 217 # COMP_WORDBREAKS to exclude those characters.  The intent is to
 218 # make option types like --date=<type> and <rev>:<path> easy to
 219 # recognize by treating each shell word as a single token.
 220 #
 221 # It is best not to set COMP_WORDBREAKS directly because the value is
 222 # shared with other completion scripts.  By the time the completion
 223 # function gets called, COMP_WORDS has already been populated so local
 224 # changes to COMP_WORDBREAKS have no effect.
