Generate function by its arguments and internal call arguments on a HAXE

Question

Trying to generate the functions to fill lthe class with api methods.

not sure how to determine function argument parameters from strings and internal call valuable arguments

            var todo:haxe.macro.Function = {args: arguments};
            
            todo.expr = macro {
                trace($v{funcname});
                
                return api_call($v{funcname});  
            };
            
            
            todo.ret = macro : Dynamic;

            var f:Field = {
                name: funcname.replaceAll('.', '_'),
                pos: Context.currentPos(),
                kind: FFun(todo),
                access: [APublic], // optional
                doc: null, // optional
                meta: [], // optional
            }

            fields.push(f);

trying to create the macro type function and add fields but got some errors.
