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 modifiations 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.
