Joose is an open-source self-hosting metaobject system for JavaScript with support for classes, inheritance, mixins, traits and aspect-oriented programming.
The Joose meta-object system is multi-paradigm. It supports class-based and prototype-based programming styles as well as class-based inheritance and role-based extension. While other JavaScript frameworks often specialize on DOM-access and AJAX, Joose specializes solely on bringing successful programming techniques to the JavaScript scripting language. Joose is thus often used in conjunction with another DOM/Ajax JavaScript framework and is tested with jQuery, YUI, Dojo, ExtJS, Prototype, Mootools and PureMVC.
Joose was heavily inspired by Moose, the object system for Perl 5 which was itself inspired by the Perl 6 object system, but unlike Perl and Moose, Joose doesn't support multiple inheritance.
Example
Two classes written in Joose:
Class("Point", {
has: {
x: {is: "rw"},
y: {is: "rw"}
},
methods: {
clear: function () {
this.setX(0);
this.setY(0);
}
}
});
Class("Point3D", {
isa: Point,
has: {
z: {is: "rw"}
},
after: {
clear: function () {
this.setZ(0);
}
}
});
Point3D is a subclass of Point. It has another attribute defined and additional code to run after running the superclass clear() method. The "rw" means the attribute is readable and writable with a pair of get/set accessors generated automatically.
