Add global not working with Proxy

[noel-schenk]

Dynamically generated functions do not work with add global.

twingEnv.addGlobal('dom', new DomGen().getInstance((subNameCallArray)=>{ return '{!'+subNameCallArray.join('.')+'!}'; }));

Standalone the function works perfectly:
https://jsfiddle.net/noelelias/4evgpko5/117/

class DomGen{
    getInstance(cb:(subNameCallArray:Array<string>)=>any):any{
        let functions = {
            get(target:any, key:any):any{
                target().subName.push(key);
                return new Proxy(target, functions);
            },
            apply(target:any, key:any, args:any){
                args.unshift("args");
                return cb(target().subName.concat(args)); //whatever cb is returning will be send back
            }
        };
        let save = new DomGen.Save([]);
        return new Proxy(()=>{return save.load(save)}, functions);
    }
    static Save = class{
        subName:any;
      constructor(subName:any){
          this.subName = subName;
      }
      load(instance:this){
        return instance;
      }
    }
}

Can you paste the Twig template that fails?

[noel-schenk]

Hey Eric sorry I this is not important rn. Can you add a label to keep this update so we can look into it at another time?

The template could look like this:

{% dom.testing.test.test() %}
//or
{% dom.testing.somethingelse.test() %}
