   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 # Compatible with bash 3.2.57.
  33 #
  34 # You can set the following environment variables to influence the behavior of
  35 # the completion routines:
  36 #
  37 #   GIT_COMPLETION_CHECKOUT_NO_GUESS
  38 #
  39 #     When set to "1", do not include "DWIM" suggestions in git-checkout
  40 #     and git-switch completion (e.g., completing "foo" when "origin/foo"
  41 #     exists).
