The submodule-dependency action allows PR authors to mark pull requests against submodules as necessary changes in order to compile a new pull request. The action automatically checks out those submodule changes, based on the contents of the pull request body.

A submodule pull-request dependency can be declared by putting "Requires <GitHub user>/<repository>#<PR number>" anywhere in the pull request body. You can also use "Depends on" with the same format.

• The action assumes that the corresponding submodule is located in a folder of the same name in the root directory of the repository.
• The action assumes that the dependency can be fetched over HTTPS.
• The action assumes that the pullfrom remote name is not in use in the submodule.
