Currently Helma-NG ships with some modules, transfered from helma 1.x

Our goal is to open a discussion, about which modules and function should ship with helma-ng, and how they should be structured in directories and modules.

== Module Struture == core

=== Core

Core could be renamed to "lang" or "javascript" because all modules here are extending original Javascript objects. Mozilla docs refers to these objects as "Core" (Core JavaScript 1.5 Reference:Global Objects:Array:indexOf at http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Objects:Array:indexOf) in their reference. What do you think? Should we stay with "Core"? Or should we change that? (matt) +/-

==== array.js

<a href="http://www.prototypejs.org">prototype.js</a> provides a bunch of neat functions: <a href="http://www.prototypejs.org/api/enumerable">Enumerable Docs</a> and <a href="http://www.prototypejs.org/api/array">Array Docs</a>. prototype.js could be offered as a replacement or addition to the current array.js -> see <a href="https://dev.helma.org/trac/helma/browser/sandbox/aida/modules/javascript/prototype.js">/sandbox/aida/modules/javascript/prototype.js</a>

===== Array.prototype.indexOf

is part of <a href="http://developer.mozilla.org/en/docs/New_in_JavaScript_1.6">JavaScript 1.6</a> and should be removed (matt)

===== Array.prototype.lastIndexOf

is part of <a href="http://developer.mozilla.org/en/docs/New_in_JavaScript_1.6">JavaScript 1.6</a> and should be removed (matt)

===== Array.prototype.contains

works, but could be replaced by prototype.js>Enumerable>include ; see: http://www.prototypejs.org/api/enumerable/include, for compaitibility reasons we could add a conatains alias

===== Array.union

Has a bug when the source objects look similar, but are not

var obj1 = {test:"one"};
var obj2 = {test:"one"};
(obj1 != obj2) === true;
var arr1 = [obj1];
var arr2 = [obj2];
Array.union(arr1, arr2); // => [{test:"one"}]
                          //    instead of [{test:"one"}, {test:"one"}]
 
Array.union could be replaced by using the prototyp.js .uniq() function. It's not very fast, but it works like expected.

// replacement using prototype.js
var result = arr1.concat(ar2).uniq();
// or:
Array.union = function() {
  var r = [];
      $A(arguments).forEach(function(arr) { r = r.concat(arr).uniq() });
      return r;
}

===== Array.intersection

not tested yet

// replacement using prototype.js
var result = arr1.intersect(ar2).uniq();
