2 # bash completion support for core Git.

4 # Copyright (C) 2006 Shawn Pearce
5 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
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 #    *) tree paths within 'ref:path/to/file' expressions
14 #
15 # To use these routines:
16 #
17 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
18 #    2) Added the following line to your .bashrc:
19 #        source ~/.git-completion.sh
20 #
21 #    3) You may want to make sure the git executable is available
22 #       in your PATH before this script is sourced, as some caching
23 #       is performed while the script loads.  If git isn't found
24 #       at source time then all lookups will be done on demand,
25 #       which may be slightly slower.
26 #
27 #    4) Consider changing your PS1 to also show the current branch:
28 #        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
29 #
30 #       The argument to __git_ps1 will be displayed only if you
31 #       are currently in a git repository.  The %s token will be
32 #       the name of the current branch.
