Question

If I want to submodule a Git repository:

https://github.com/shadowhand/paypal

…that has a config file:

https://github.com/shadowhand/paypal/blob/master/config/paypal.php

…how do I contribute to the project without committing my version of the config file?

Answer 1

When you commit, don’t add that file:

git add classes/paypal.php
...
# don't add config/paypal.php
git commit

Before committing, check with git status that you haven’t staged any modifications to the config – if you accidentally have, use git reset HEAD config/paypal.php to unstage them.

(And for what it’s worth, this doesn’t really have anything to do with the fact that you’re using this repository as a submodule.)
