Couple of things we will need to think about with this when testing actually - the first is if the child class overrides something in the parent class we want to take the childs implementation not the parents

class Base {
    @method
    test() {

    }
}

class Test < Base {
    @method1234
    test() {

    }
}

print(Test.methodAnnotations); // {"test": {"method": nil}}

// Where I would expect {"test": {"method1234": nil}}

I would imagine some sort of key check in copyAnnotations should do the trick.

Similarly (not sure why this would happen) but if we modify the annotation value on the child we want to make sure it doesn't update the parent (essentially we would want a deep copy)

class Base {
    @method
    test() {

    }
}

class Test < Base {

}

Test.methodAnnotations['test']['method'] = 10;

print(Test.methodAnnotations); // {"test": {"method": 10}}
print(Base.methodAnnotations); // {"test": {"method": 10}}

Great catches. Impl updated as well as tests.

Sorry couple more comments!

[briandowns]

All set!

Nicceeee thanks for this!!

[briandowns]

No prob. Thanks for the quick reviews! My ORM is really coming along now that all of the annotation features are in!

[Jason2605]

Awesome! Definitely be interested to see it! Also side note, I ended up using Wanbli for a little side project of mine :)

[briandowns]

Open to any and all feedback on that. I don't really have it in a stable state yet so use with caution!

It’s all good just a little tool I’m using in the house to track some smart plug usage! I’ll potentially PR some things across for it but it’s been a fun project

Here's the ORM. Suuuuper naive... Not finished but works. https://github.com/briandowns/kahless . Gonna get an example together using Kahless and Wanbli together.

This looks really cool!
