NAME

       gitmodules - Defining submodule properties

SYNOPSIS

       $GIT_WORK_DIR/.gitmodules

DESCRIPTION

       The .gitmodules file, located in the top-level directory of a Git working tree, is a text
       file with a syntax matching the requirements of git-config(1).

       The file contains one subsection per submodule, and the subsection value is the name of
       the submodule. The name is set to the path where the submodule has been added unless it
       was customized with the --name option of git submodule add. Each submodule section also
       contains the following required keys:

       submodule.<name>.path
           Defines the path, relative to the top-level directory of the Git working tree, where
           the submodule is expected to be checked out. The path name must not end with a /. All
           submodule paths must be unique within the .gitmodules file.

       submodule.<name>.url
           Defines a URL from which the submodule repository can be cloned. This may be either an
           absolute URL ready to be passed to git-clone(1) or (if it begins with ./ or ../) a
           location relative to the superproject’s origin repository.

       In addition, there are a number of optional keys:

       submodule.<name>.update
           Defines the default update procedure for the named submodule, i.e. how the submodule
           is updated by "git submodule update" command in the superproject. This is only used by
           git submodule init to initialize the configuration variable of the same name. Allowed
           values here are checkout, rebase, merge or none. See description of update command in
           git-submodule(1) for their meaning. For security reasons, the !command form is not
           accepted here.

       submodule.<name>.branch
           A remote branch name for tracking updates in the upstream submodule. If the option is
           not specified, it defaults to master. A special value of .  is used to indicate that
           the name of the branch in the submodule should be the same name as the current branch
           in the current repository. See the --remote documentation in git-submodule(1) for
           details.

       submodule.<name>.fetchRecurseSubmodules
           This option can be used to control recursive fetching of this submodule. If this
           option is also present in the submodules entry in .git/config of the superproject, the
           setting there will override the one found in .gitmodules. Both settings can be
           overridden on the command line by using the "--[no-]recurse-submodules" option to "git
           fetch" and "git pull".

       submodule.<name>.ignore
           Defines under what circumstances "git status" and the diff family show a submodule as
           modified. The following values are supported:

           all
               The submodule will never be considered modified (but will nonetheless show up in
               the output of status and commit when it has been staged).

           dirty
               All changes to the submodule’s work tree will be ignored, only committed
               differences between the HEAD of the submodule and its recorded state in the
               superproject are taken into account.

           untracked
               Only untracked files in submodules will be ignored. Committed differences and
               modifications to tracked files will show up.

           none
               No modifications to submodules are ignored, all of committed differences, and
               modifications to tracked and untracked files are shown. This is the default
               option.

           If this option is also present in the submodules entry in .git/config of the
           superproject, the setting there will override the one found in .gitmodules.

           Both settings can be overridden on the command line by using the "--ignore-submodules"
           option. The git submodule commands are not affected by this setting.

       submodule.<name>.shallow
           When set to true, a clone of this submodule will be performed as a shallow clone (with
           a history depth of 1) unless the user explicitly asks for a non-shallow clone.

EXAMPLES

       Consider the following .gitmodules file:

           [submodule "libfoo"]
                   path = include/foo
                   url = git://foo.com/git/lib.git

           [submodule "libbar"]
                   path = include/bar
                   url = git://bar.com/git/lib.git

       This defines two submodules, libfoo and libbar. These are expected to be checked out in
       the paths include/foo and include/bar, and for both submodules a URL is specified which
       can be used for cloning the submodules.
