#
# bash completion support for core Git.
#
# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
# Distributed under the GNU General Public License, version 2.0.
#
# The contained completion routines provide support for completing:
#
# *) local and remote branch names
# *) local and remote tag names
# *) .git/remotes file names
# *) git 'subcommands'
# *) tree paths within 'ref:path/to/file' expressions
# *) common --long-options
#
# To use these routines:
#
# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
# 2) Added the following line to your .bashrc:
# source ~/.git-completion.sh
#
# 3) You may want to make sure the git executable is available
# in your PATH before this script is sourced, as some caching
# is performed while the script loads. If git isn't found
# at source time then all lookups will be done on demand,
# which may be slightly slower.
#
# 4) Consider changing your PS1 to also show the current branch:
# PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
#
# The argument to __git_ps1 will be displayed only if you
# are currently in a git repository. The %s token will be
# the name of the current branch.
#
# To submit patches:
#
# *) Read Documentation/SubmittingPatches
# *) Send all patches to the current maintainer:
#
# "Shawn O. Pearce" <spearce@spearce.org>
#
# *) Always CC the Git mailing list:
#
# git@vger.kernel.org
