Object iterators added.

[milichev]

Added support of object property iterators, e.g. for (key in obj) {...}

Notation is similar to array iterators, '@' char is used instead of '~':

{{@ {one: 1, two: 2, three: 3} :val :key}}
    {{=key}} = {{=val}}
{{@}}

Also, this can iterate only own properties – with additional '@':

{{ obj = (function() {
    function O() {
        this.four = 4;
    }
    O.prototype = { one: 1, two: 2, three: 3 };
    return new O;
})(); }}

{{@@ obj :val :key}}
    {{=key}} = {{=val}}
{{@@}}

And tests for this:

describe("iterate object (for..in)", function() {
    function Obj() {
        this.awesome = "doT.js";
    }
    Obj.prototype = {
        one: 1,
        2: "two",
        THREE: 3
    };

    var obj;

    beforeEach(function() {
        obj = new Obj();
    });

    it("should iterate all object properties", function() {
        var tpl = doT.compile('{{@ it :val :key}}[{{=key}}={{=val}}]{{@}}');
        var exp = '';
        for (var k in obj) {
            exp += "[" + k + "=" + obj[k] + "]";
        }
        expect(tpl(obj)).toBe(exp);
    });

    it("should iterate only own properties", function() {
        var tpl = doT.compile('{{@@ it :val :key}}[{{=key}}={{=val}}]{{@@}}');
        var exp = '';
        for (var k in obj) {
            if (obj.hasOwnProperty(k)) {
                exp += "[" + k + "=" + obj[k] + "]";
            }
        }
        expect(tpl(obj)).toBe(exp);
    });
});

[VitalyKovalev]

same q to @Olando, do you support this project?

[zevero]

Is there a case, where you would like to iterate without checking for own properties?

Please pull!!!
