@-style attributes in js...

    just wanted to confirm...it's still not possible to use @-style attributes in javascript in max 5? (or, has it been possible all along, and i just didn't know it?)

      In 4.6, I just parse them using some prewritten code.
      Basically, I create the variable and default value, and add its name to an array of valid attribute names. Then I parse jsarguments for properly-formed pairs which match the format @ATTR1 VALUE (checking for the presence of ATTR1 in the atribute array). Finally I use an eval to set the value of a variable corresponding to the attribute name (ATTR=VALUE).
      My parser also handles position-dependent arguments.
      Apart from the code used to do the parsing etc (which isnt particularly optimised, so about 60 lines long), which could be included in a code template, that reduces my argument and attribute parsing to the following:
      args = new argHandler;
      // note - declare arguments in order;
      var ARG1 = 100;
      args.setUpArgument("ARG1");
      var ARG2 = 0;
      args.setUpArgument("ARG2");
      var ATTR1 = 100;
      args.setUpAttribute("ATTR1");
      args.argumentParser(jsarguments);
      // required : reads and evals supplied arguments
      args.reportAttributes();
      // posts all attributes as per a non-js patcher
