Create diff patch for a composer package

问题

I'm contributing to quite a large project with lots of submodules, and using repositories section of composer.json etc. Sometimes it is handy to edit files in the vendor directory instead of the real repository (e.g. there are some submodules with tests for the other ones).

Then I use composer update and a message pops up: Discard changes [y,n,v,d,s,?]?

I can choose the option d, thus getting a nice diff patch I can later use for the real Git repository. Can I have such a patch in a simpler way?

回答1:

You can go to dependency directory and use git to show diff:

cd vendor/somevendor/somepackage
git diff HEAD

This is what Composer is actually doing.
