  13DESCRIPTION
  14-----------
  15
  16The `.gitmodules` file, located in the top-level directory of a Git
  17working tree, is a text file with a syntax matching the requirements
  18of linkgit:git-config[1].
  19
  20The file contains one subsection per submodule, and the subsection value
  21is the name of the submodule. The name is set to the path where the
  22submodule has been added unless it was customized with the '--name'
  23option of 'git submodule add'. Each submodule section also contains the
  24following required keys:
  25
  26submodule.<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.
  31
  32submodule.<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.
  37
  38In addition, there are a number of optional keys:
  39
  40submodule.<name>.update::
  41        Defines what to do when the submodule is updated by the superproject.
  42        If 'checkout' (the default), the new commit specified in the
  43        superproject will be checked out in the submodule on a detached HEAD.
  44        If 'rebase', the current branch of the submodule will be rebased onto
  45        the commit specified in the superproject. If 'merge', the commit
  46        specified in the superproject will be merged into the current branch
  47        in the submodule.
  48        If 'none', the submodule with name `$name` will not be updated
  49        by default.
  50
  51        This config option is overridden if 'git submodule update' is given
  52        the '--merge', '--rebase' or '--checkout' options.
  53
  54submodule.<name>.branch::
  55        A remote branch name for tracking updates in the upstream submodule.
  56        If the option is not specified, it defaults to 'master'.  See the
  57        `--remote` documentation in linkgit:git-submodule[1] for details.
  58+
  59This branch name is also used for the local branch created by
  60non-checkout cloning updates.  See the `update` documentation in
  61linkgit:git-submodule[1] for details.
  62
  63submodule.<name>.fetchRecurseSubmodules::
  64        This option can be used to control recursive fetching of this
  65        submodule. If this option is also present in the submodules entry in
  66        .git/config of the superproject, the setting there will override the
  67        one found in .gitmodules.
  68        Both settings can be overridden on the command line by using the
  69        "--[no-]recurse-submodules" option to "git fetch" and "git pull".
  70
  71submodule.<name>.ignore::
  72        Defines under what circumstances "git status" and the diff family show
  73        a submodule as modified. When set to "all", it will never be considered
  74        modified, "dirty" will ignore all changes to the submodules work tree and
  75        takes only differences between the HEAD of the submodule and the commit
  76        recorded in the superproject into account. "untracked" will additionally
  77        let submodules with modified tracked files in their work tree show up.
  78        Using "none" (the default when this option is not set) also shows
  79        submodules that have untracked files in their work tree as changed.
  80        If this option is also present in the submodules entry in .git/config of
  81        the superproject, the setting there will override the one found in
  82        .gitmodules.
  83        Both settings can be overridden on the command line by using the
  84        "--ignore-submodule" option. The 'git submodule' commands are not
  85        affected by this setting.

  88EXAMPLES
  89--------
  90
  91Consider the following .gitmodules file:
  92
  93        [submodule "libfoo"]
  94                path = include/foo
  95                url = git://foo.com/git/lib.git
  96
  97        [submodule "libbar"]
  98                path = include/bar
  99                url = git://bar.com/git/lib.git
 100
 101
 102This defines two submodules, `libfoo` and `libbar`. These are expected to
 103be checked out in the paths 'include/foo' and 'include/bar', and for both
 104submodules a URL is specified which can be used for cloning the submodules.
