Ever had a submodule that you wanted to keep the full history of, but you no longer wanted it is a submodule? You want it as part of the main project. This set of commands allows you to do just that - pulling the submodule's history and incorporating it into the main project.

unsubmodulify_in_git

#!/bin/bash

# Just in case something goes wrong, let's do this un-submodulifying on a new branch.
git checkout new_branch

# You need to go in and remove the SUBMODULE_DIR project from your .gitmodules file
# Save the URL that the submodule points to.
vim .gitmodules 

# We're going to completely wipe out the SUBMODULE_DIR from your project...trust me...
git rm --cached SUBMODULE_DIR
git commit -am "Removed SUBMODULE_DIR as submodule" 
rm -rf SUBMODULE_DIR

# Now we're going to add that SUBMODULE_DIR as a remote. You can get this URL from
# what you removed when you edited the .gitmodules file.
git remote add -f TEMP_REMOTE git@github.com:Caveat4U/submodule_project.git

# Basically? Merge the history together from the submodule and this project.
git merge -s ours --no-commit TEMP_REMOTE/master 
git read-tree --prefix=SUBMODULE_DIR -u TEMP_REMOTE/master 

# FINALLY, commit all these new changes
git commit -am "SUBMODULE_DIR is now part of main project"


# Now when you're done with all that, push to your new_branch, and create a pull request from new_branch -> master and everything will be green to go.
