6 gitmodules - defining submodule properties
10 $GIT_WORK_DIR/.gitmodules
16 The `.gitmodules` file, located in the top-level directory of a Git
17 working tree, is a text file with a syntax matching the requirements
18 of linkgit:git-config[1].
20 The file contains one subsection per submodule, and the subsection value
21 is the name of the submodule. The name is set to the path where the
22 submodule has been added unless it was customized with the '--name'
23 option of 'git submodule add'. Each submodule section also contains the
24 following required keys:
26 submodule.<name>.path::
27 Defines the path, relative to the top-level directory of the Git
28 working tree, where the submodule is expected to be checked out.
29 The path name must not end with a `/`. All submodule paths must
30 be unique within the .gitmodules file.
32 submodule.<name>.url::
33 Defines a URL from which the submodule repository can be cloned.
34 This may be either an absolute URL ready to be passed to
35 linkgit:git-clone[1] or (if it begins with ./ or ../) a location
36 relative to the superproject's origin repository.
38 submodule.<name>.update::
39 Defines what to do when the submodule is updated by the superproject.
40 If 'checkout' (the default), the new commit specified in the
41 superproject will be checked out in the submodule on a detached HEAD.
42 If 'rebase', the current branch of the submodule will be rebased onto
43 the commit specified in the superproject. If 'merge', the commit
44 specified in the superproject will be merged into the current branch
46 If 'none', the submodule with name `$name` will not be updated
49 This config option is overridden if 'git submodule update' is given
50 the '--merge', '--rebase' or '--checkout' options.
52 submodule.<name>.branch::
53 A remote branch name for tracking updates in the upstream submodule.
54 If the option is not specified, it defaults to 'master'. See the
55 `--remote` documentation in linkgit:git-submodule[1] for details.
57 submodule.<name>.fetchRecurseSubmodules::
58 This option can be used to control recursive fetching of this
59 submodule. If this option is also present in the submodules entry in
60 .git/config of the superproject, the setting there will override the
61 one found in .gitmodules.
62 Both settings can be overridden on the command line by using the
63 "--[no-]recurse-submodules" option to "git fetch" and "git pull".
65 submodule.<name>.ignore::
66 Defines under what circumstances "git status" and the diff family show
67 a submodule as modified. When set to "all", it will never be considered
68 modified, "dirty" will ignore all changes to the submodules work tree and
69 takes only differences between the HEAD of the submodule and the commit
70 recorded in the superproject into account. "untracked" will additionally
71 let submodules with modified tracked files in their work tree show up.
72 Using "none" (the default when this option is not set) also shows
73 submodules that have untracked files in their work tree as changed.
74 If this option is also present in the submodules entry in .git/config of
75 the superproject, the setting there will override the one found in
77 Both settings can be overridden on the command line by using the
78 "--ignore-submodule" option. The 'git submodule' commands are not
79 affected by this setting.
85 Consider the following .gitmodules file:
89 url = git://foo.com/git/lib.git
93 url = git://bar.com/git/lib.git
96 This defines two submodules, `libfoo` and `libbar`. These are expected to
97 be checked out in the paths 'include/foo' and 'include/bar', and for both
98 submodules a URL is specified which can be used for cloning the submodules.
