How to use package name from shared scripts instead of INIT_CWD in monorepo?

[danielpza]

I want to reuse a script across different packages similar to how it is done in https://yarnpkg.com/getting-started/qa/#how-to-share-scripts-between-workspaces, but instead of the directory I want to use the package name. Is there a way to do it?

For example I'm using turborepo for running a script, but same could be for yarn workspaces plugin:

// root package.json
"scripts": {
  "g:dev": "yarn turbo run dev --filter <$PACKAGE_NAME>",
  "g:dev:ws": "yarn workspaces foreach run dev --filter <$PACKAGE_NAME> -R"
}

NOTE PACKAGE_NAME would be a desired env variable similar to INIT_CWD

// packages/test-package/package.json
"scripts": {
  "dev": "node server.js"
}

Example invocation: yarn packages/test-package g:dev

Using INIT_CWD here doesn't work because we need the actual package name not the directory
