Git is it possible to show the current tag of a submodule?

is it possible to show the tag of a current submodule without having to be inside its directory?

I would want to do something like

git describe --tags <submodule_dir>

and return the particular tag.

Solution

  • You can use git submodule foreach (doc here) to run a command from within each submodule :

    # something like the following should work :
git submodule foreach 'echo $name : `git describe --tags`'

    For a command such as git describe (which extracts its information only from the .git/ directory, not from the working tree), you can pass the git directory as an argument to the git command :

    # the .git directory for a submodule can be found under .git/modules/module_name :
git --git-dir=.git/modules/module_name describe --tags
