Output of Firestore rules.debug should specify line number

[nwaughachukwuma]

When working with Firestore rules on the emulator and using debug to print security rules language objects, variables and statement results as they are being evaluated by the security rules engine, it's often necessary to know the file name and line number a printed output references in any case where there're several debug statements across multiple test files.

Simply put, if I have several debug statements as shown below and check the outputs written to firestore-debug.log, I should know where each output is coming from - it's sometimes cumbersome when there're so much content in the log and it's easy to get lost looking for debug output.

// an example function in a sample firestore.rules file 
match /products/{productId} {
   function isAuthenticated() {
     return request.auth != null;
   }
   function oneOf(primeMembers) {
     let ownerId = debug(resource.data.get('ownerId', ''));

     let owner = get(/databases/$(database)/documents/owner/$(ownerId));
     let primeMember = owner ? (owner.data.uid in primeMembers): false;

     return isAuthenticated() && primeMember;
   }
}

Potential output in firestore-debug.log

...
file: db.products.test.ts
L60: string_value: "u5jxu95H9xbv"

Hi, if I'm understanding correctly this is a feature request for the emulators. Let me know if I'm wrong and this is related to the JS SDK. Otherwise, the repo for the emulators is https://github.com/firebase/firebase-tools (which encompasses the Firebase CLI). You can create an issue there and label it as a feature request.
