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 #    *) tree paths within 'ref:path/to/file' expressions
14 #    *) file paths within current working directory and index
15 #    *) common --long-options
16 #
17 # To use these routines:
18 #
19 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
20 #    2) Add the following line to your .bashrc/.zshrc:
21 #        source ~/.git-completion.sh
22 #    3) Consider changing your PS1 to also show the current branch,
23 #       see git-prompt.sh for details.
24 #
25 # If you use complex aliases of form '!f() { ... }; f', you can use the null
26 # command ':' as the first command in the function body to declare the desired
27 # completion style.  For example '!f() { : git commit ; ... }; f' will
28 # tell the completion to use commit completion.  This also works with aliases
29 # of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".

87 # on the command line:

91 #       then

95 # The argument should be a collection of characters from the list of
96 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
97 # characters.
98 #
99 # This is roughly equivalent to going back in time and setting
100 # COMP_WORDBREAKS to exclude those characters.  The intent is to
101 # make option types like --date=<type> and <rev>:<path> easy to
102 # recognize by treating each shell word as a single token.
103 #
104 # It is best not to set COMP_WORDBREAKS directly because the value is
105 # shared with other completion scripts.  By the time the completion
106 # function gets called, COMP_WORDS has already been populated so local
107 # changes to COMP_WORDBREAKS have no effect.
