NodeJS bridgeThe Objective-C ⇆
NodObjC exposes the Objective-C runtime to NodeJS in a high-level, easy
to use fashion. It uses the
BridgeSupport files to dynamically generate an
API from an Objective-C "Framework" at runtime, and uses
dynamically interact with Objective-C's runtime.
NodObjC is similar in nature to the other popular Objetive-C
Note: This lib is still very much under development. It is not ready for primetime quite yet. Watch this project to follow the updates!
This module offers a bi-directional bridge between NodeJS and the Objective-C runtime. What does that mean exactly? Well due to the design of the Objective-C runtime, it is possible to port the entire API to other languages. There are quite a few bridges for Obj-C so one for node was a necessity.
// In NodObjC, you send a message to an object like: obj('func', arg)
In Objective-C, the names of methods are part of the arguments that you pass along, so let's look at a method that takes more than one argument:
array('insertObject', obj, 'atIndex', 5)
So the even numbered arguments are the parts of the method name that will be
invoked, and the odd numbered arguments are the Obj-C arguments themselves. In
the above example, the
insertObject:atIndex: function will be invoked.
NodObjC, not only is the Objective-C runtime exposed, but so are the
corresponding C functions that usually go along with these APIs (thanks to
BridgeSupport). So for example, we can make an
NSRect by calling the
NSMakeRect() C function:
$.NSMakeRect(5, 10, 8, 30) // -> NSRect struct
There's literally thousands of other Objective-C resources and tutorials out there, especially Apple's offial documentation. So hopefully you get the gist of it here.
