Removing a git submodule is a mess... some bash script to ease the process and to make sure there's nothing left unsaved before removing.
#!/usr/bin/env bash
if [ -z "$1" ]; then
echo "Missing submodule"
exit 1
fi
sn=$1
# verify that the folder is not deleted while there are unsaved changes
if [ -d $sn/.git ]; then
cd $sn
if [ "$?" -eq "0" ]; then
status=$(git status --porcelain)
if [ -n "${status}" ]; then
printf '\n\n!!! CAUTION !!!\n\n';
printf 'Submodule contains untracked/unstaged/unpushed changes:\n'
echo ${status}
printf "\n\n"
read -n 1 -p 'Are you sure you want to continue? [Enter]' con;
echo '';
if [ "${con}" != "" ]; then
echo "abort"
exit 1
fi
fi
read -n 1 -p 'Shall the repo be pushed to origin before deletion? [Enter]' con
if [ "${con}" = "" ]; then
git push
fi
echo ''
cd -
fi
fi
function remove() {
line=$(cat ${1} | grep -n "\[submodule \"${sn}\"\]")
line="${line:0:1}"
end="$(($line+2))"
sed -i.bak "$line,${end}d" ${1}
}
remove .gitmodules
remove ".git/config"
printf "\n\nDiff .gitmodules"
diff .gitmodules .gitmodules.bak
printf "\n\nDiff .git/config\n"
diff .git/config .git/config.bak
printf "\n\n"
# verify removed lines are ok
read -n 1 -p "Diffs of .gitmodules and .git/config ok? [Enter]" con;
if [ "$con" != "" ]; then
echo "Aborted.."
mv .gitmodules.bak .gitmodules
mv .git/config.bak .git/config
echo "Changes reverted"
exit 1
fi
git add .gitmodules
git rm -rf .git/modules/${1}
git commit -m "remove submodule ${1}"
rm -rf ${1}
echo "Done!"
