1 # bash/zsh completion support for core Git.
2 #
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 # 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 # completion (e.g., completing "foo" when "origin/foo" exists).
