This command can be used to initialize, update and inspect submodules. It uses a .gitmodules file, readable by git-config, in the top level directory of the 'superproject' to specify a mapping between submodule paths and repository url. Example .gitmodules layout: [module "git"] url = git://git.kernel.org/pub/scm/git/git.git With this entry in .gitmodules (and a commit reference in the index entry for the path "git"), the command 'git submodule init' will clone the repository at kernel.org into the directory "git". Known issues ============ There is currently no way to override the url found in the .gitmodules file, except by manually creating the subproject repository. The place to fix this in the script has a rather long comment about a possible plan. Funny paths will be quoted in the output from git-ls-files, but git-submodule does not attempt to unquote (or even detect the presence of) such paths.

NAME
|
|
----
|
|
git-submodule - Initialize, update or inspect submodules
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-submodule' [--quiet] [--cached] [status|init|update] [--] [<path>...]
|
|
|
|
|
|
COMMANDS
|
|
--------
|
|
status::
|
|
Show the status of the submodules. This will print the SHA-1 of the
|
|
currently checked out commit for each submodule, along with the
|
|
submodule path and the output of gitlink:git-describe[1] for the
|
|
SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
|
|
initialized and `+` if the currently checked out submodule commit
|
|
does not match the SHA-1 found in the index of the containing
|
|
repository. This command is the default command for git-submodule.
|
|
|
|
init::
|
|
Initialize the submodules, i.e. clone the git repositories specified
|
|
in the .gitmodules file and checkout the submodule commits specified
|
|
in the index of the containing repository. This will make the
|
|
submodules HEAD be detached.
|
|
|
|
update::
|
|
Update the initialized submodules, i.e. checkout the submodule commits
|
|
specified in the index of the containing repository. This will make
|
|
the submodules HEAD be detached.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
-q, --quiet::
|
|
Only print error messages.
|
|
|
|
--cached::
|
|
Display the SHA-1 stored in the index, not the SHA-1 of the currently
|
|
checked out submodule commit. This option is only valid for the
|
|
status command.
|
|
|
|
<path>::
|
|
Path to submodule(s). When specified this will restrict the command
|
|
to only operate on the submodules found at the specified paths.
|
|
|
|
FILES
|
|
-----
|
|
When cloning submodules, a .gitmodules file in the top-level directory
|
|
of the containing repository is used to find the url of each submodule.
|
|
This file should be formatted in the same way as $GIR_DIR/config. The key
|
|
to each submodule url is "module.$path.url".
