I am trying to get a handle on git and am having some difficulty  
understanding how to manage my projects. My project was built outside of  
version control where my extensions used were all git-cloned into my  
project. Two of the extensions (page\_attachments and copy\_move) are  
using  
previous revisions set up as local branches. The project directory was  
then  
initialized as a local git repo and the remote.upload.url variable was  
set  
up. I can ‘git push upload master’ to my online git server at Rails  
Playground. It all seems to work properly, but if I try and git-clone my  
project to test if it’s working, none of the extensions have any files  
in  
the vendor/extensions/extensionX directories.

In the past when I was using subversion to manage my projects a  
git-cloned  
extension maintained its content. How should I be adding extensions to  
my  
project so that travel with the project?

The typical method is with `git submodule`. So if I were to install  
page\_attachments manually, it would be like so:

$ git submodule add  
git://github.com/radiant/radiant-page-attachments-extension.git  
vendor/extensions/page\_attachments  
$ git submodule init && git submodule update

You’ll likely need to remove the original extension installation before  
you use submodules. Once it’s installed correctly as a submodule, you  
can use pull/reset within the extension directory to put it on the  
revision that you prefer to use, then commit to the main project to lock  
in that revision.

Thanks for your help Sean. Now I have another related question. I am  
using  
the subscriber\_lists extension but on my copy I changed a couple of  
things.  
Since I cannot use submodule to include the extension, how can I tell  
git  
ignore the fact that it was a cloned copy of the one on github? Or,  
barring  
that, how can I download a copy of the code from github (think svn  
export)  
to make the changes and track the code in my own repo?

Thanks,

Nate

One thing I forgot to mention. Whenever you clone the project again,  
you need to run:

$ git submodule init && git submodule update

This will make sure you download the submodules.

I would suggest forking on github, pushing up your changes to your fork,  
and then creating the submodule from the fork. If you don’t want to  
track other branches/forks but just keep your changes in the Radiant  
project, just clone the extension (not as a submodule) and then remove  
its .git directory.

Thanks. I am really not feeling the git love right now so I am going to  
try  
and avoid adding more complexity to my situation by starting a fork. I  
did  
remove the .got directory from my locally cloned copy of the  
subscriber\_lists extension, but when I run git submodule I keep getting  
this  
error:

No submodule mapping found in .gitmodules for path  
‘vendor/extensions/subscriber\_lists’

Preceding the error, I git a list of the extensions that I have set up  
as  
submodules and there is one (tags) that should show up as a submodule as  
well, but nothing gets past this error.

To remove the .git directory did an ‘rm -rf’ to remove it and a ‘git rm’  
just to make sure it was out of git.

Any ideas?

Nevermind. I hadn’t done a ‘git add .’ and commit to add the files to  
the  
repo. It’s working now.

Thanks,
