How to remove a Submodule from your Git repository
In this short post I'll share how to do just that.
We all know having submodules in Git is very handy. You don't have to check all of the code in, just the reference and, when needed, initialize them.
Traces of submodules
When installing a submodule in Git it does a couple of things. It adds a
record to your
.gitmodules file. When this file doesn't exist it will create one. An example of this is:
[submodule "some/nice/folder"] path = some/nice/folder url = git://github.com/your_idol/awesome.git
Secondly, it adds the URLs/mappings to your
.git/config file. This is done when you use
git init submodule.
Last but not least, it adds references to the submodule in your commits.
Fine, but how do I get rid of them?
The first two traces are easy enough to remove. Just open up
.gitmodules and remove the reference to it. Next, open up
.git/config and remove the mappings there as well. Last, but not least, use the following command from the root directory of your git repository:
$ git rm --cached path/to/submodule
Notice that you have to leave out the trailing slash, else the command will moan about it.
And that's it! Your submodule is gone.
Hope this helps anyone.
