Yarn re-patch package already patched

[finnmerlett]

I love yarn patch, a great built-in implementation of patch-package. But often I need to redo patches I created earlier, and update them with new alterations. At present, I have to run yarn patch package-in-question, then manually re-do every change, then add in the new changes.

Is there any way to apply the old patch to the temp folder created by yarn patch so this step is not necessary? Or is there any other way to update a yarn patch? Many thanks.

You can. ie: yarn patch "foo@patch:foo@npm%3A11.1.0#./.yarn/patches/foo-npm-11.1.0-044300d42a.patch::version=11.1.0&hash=9322f9&locator=frontend%40workspace%3A."
you can do yarn why foo to find what to put in inside the quotes, make sure you have package-name@ prefixed
