   2 # bash completion support for core Git.
   3 #
   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.
