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

87 # This function can be used to access a tokenized list of words
88 # on the command line:
89 #
90 #       __git_reassemble_comp_words_by_ref '=:'

92 #       then
93 #               ...
94 #       fi
95 #
96 # The argument should be a collection of characters from the list of
97 # word completion separators (COMP_WORDBREAKS) to treat as ordinary
98 # characters.
99 #
100 # This is roughly equivalent to going back in time and setting
101 # COMP_WORDBREAKS to exclude those characters.  The intent is to
102 # make option types like --date=<type> and <rev>:<path> easy to
103 # recognize by treating each shell word as a single token.
104 #
105 # It is best not to set COMP_WORDBREAKS directly because the value is
106 # shared with other completion scripts.  By the time the completion
107 # function gets called, COMP_WORDS has already been populated so local
108 # changes to COMP_WORDBREAKS have no effect.
