6 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
7 # Distributed under the GNU General Public License, version 2.0.
8 #
9 # The contained completion routines provide support for completing:
10 #
11 #    *) local and remote branch names
12 #    *) local and remote tag names
13 #    *) .git/remotes file names
14 #    *) git 'subcommands'
15 #    *) tree paths within 'ref:path/to/file' expressions
16 #    *) common --long-options
17 #
18 # To use these routines:
19 #
20 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
21 #    2) Added the following line to your .bashrc:
22 #        source ~/.git-completion.sh
23 #
24 #    3) You may want to make sure the git executable is available
25 #       in your PATH before this script is sourced, as some caching
26 #       is performed while the script loads.  If git isn't found
27 #       at source time then all lookups will be done on demand,
28 #       which may be slightly slower.
29 #
30 #    4) Consider changing your PS1 to also show the current branch:
31 #        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
32 #
33 #       The argument to __git_ps1 will be displayed only if you
34 #       are currently in a git repository.  The %s token will be
35 #       the name of the current branch.
36 #
37 #       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
38 #       value, unstaged (*) and staged (+) changes will be shown next
39 #       to the branch name.  You can configure this per-repository
40 #       with the bash.showDirtyState variable, which defaults to true
41 #       once GIT_PS1_SHOWDIRTYSTATE is enabled.
42 #

44 #
45 #    *) Read Documentation/SubmittingPatches
46 #    *) Send all patches to the current maintainer:
