`@yarnpkg/plugin-patch`

This plugin adds support for the patch: protocol.

This plugin is included by default in Yarn.

Run yarn patch <package name> and edit the resulting folder.
Once you're ready, run yarn patch-commit -s <patch folder> to store the result inside a .patch file.
Add the patch: protocol to your dependencies as such:

{
  "dependencies": {
    "lodash": "patch:lodash@1.0.0#./my-patch-file.patch"
  }
}

You cannot add dependencies through the patch: protocol. Check this FAQ entry for more details.
