gitmodules - Defining submodule properties
$GIT_WORK_TREE/.gitmodules
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 the 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, but not !command (for security reasons). See
the description of the update command in git-submodule(1) for
more details.
submodule.<name>.branch
A remote branch name for tracking updates in the upstream
submodule. If the option is not specified, it defaults to the
remote HEAD. 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 submodule’s
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 submodule’s 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.
Git does not allow the .gitmodules file within a working tree to
be a symbolic link, and will refuse to check out such a tree
entry. This keeps behavior consistent when the file is accessed
from the index or a tree versus from the filesystem, and helps
Git reliably enforce security checks of the file contents.
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.
