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

132 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
133 # characters.
134 #
