hyperloop
DESCRIPTION
Hyperloop will make Titanium more native then ever, but also more standard JavaScript at the same time. As an example, the API will now be fully prototypal, and because it’s all (Hyperloop) JavaScript you can extend every bit of it without touching Objective-C or JAVA.TRANSCRIPT

What’s next?
Ti.Next (Titanium 4.0)•Significant re-architecture of Titanium
• (Mostly) same API
• Incredible performance boost and reduction in app size
• Improved Extensibility
•Windows support
Ti.Next Foundation•Foundation of Ti.Next is a new compiler, built from the ground up for performance, extensibility
•Open Source under Apache Public License v2
•http://github.com/appcelerator/hyperloop
•Over a year of R&D already on Hyperloop (4th generation compiler under development)
Hyperloop integrations•Titanium traditional (all-in)
•Titanium in Native
•Native in Titanium
•Titanium in other frameworks (PhoneGap, Xamarin)
•Pure Native (Hyperloop only)
What is Hyperloop?•Hyperloop turns JS code into native code by mapping the native APIs into JS syntax
•Hyperloop will be (mainly) used by Titanium platform developers to build Titanium APIs or modules
•A more traditional compiler architecture: – Front-end (parse and transform JS AST) – Back-end (generate native, platform specific code) – +Metabase (metadata about target platform)
Hyperloop iOS example!!@import('Foundation'); @import('UIKit'); !var view = new UIView(CGRectMake(100,100,50,50)); view.backgroundColor = UIColor.redColor(); var window = new UIWindow(); window.addSubview(view); window.makeKeyAndVisible()
Hyperloop Front-end•Front-end uses UglifyJS to turn JS code into an AST and then perform transformations on the code to make it more suitable for native generation
Example of Front-end translations!
Foo.bar = 1 Foo_set_bar(1) !
Foo.bar() Foo_bar() !
var foo = new Bar() Bar_constructor() !
foo.bar(1) Bar_bar(foo, 1)
Hyperloop Back-end•Back-end generates C/C++ code for target platform
•~90% of the back-end code is reusable for all platforms supported
•10% is basically specific syntax for things like calling methods, properties, etc. and other platform specific nuances (differences in file extensions, etc.)
Hyperloop Metabase•Defined platform APIs in JSON format
•Automatically generate for all platforms supported
•Large tree of all supported APIs (classes, functions, types, etc.)
•Supports both C and platform specific languages (Objective-C, Java, etc.)
•Uses Clang (+platform specific tools) to generate
•Rich metadata about the platform
Hyperloop Metabase iOS example
Hyperloop Metabase Android example
Hyperloop JS engine•Unified JS engine for all platforms based on JavaScriptCore – iOS 7.0+ comes with engine installed – Port for Windows and Android
!
•Performance testing showed JSC was basically native speed
Hyperloop code rewriting•Huge blocks of code will be optimized into pure native code generation
•No penalty for “JS bridge” like in current Titanium
•JS engine runs on main UI Thread: – No thread context switching / creation overhead – Will provide background worker for asynchronous non-
blocking tasks
The proof is in the pudding!
DEMO
Ti.Next•Titanium APIs are being re-written using Hyperloop JS syntax and compiled using Hyperloop compiler
•Titanium APIs (and native APIs) will be first class JS objects •Goal is to generate API interfaces, test cases from API documentation
•Full Node.js require implementation •Will likely deprecate platform specific APIs and provide a compatibility module
•Likely will reduce size of overall API •Titanium APIs will use module design
Ti.Next modules•Migration path for modules (still trying to determine)
•Packaging likely will change and modules will be expressed in Hyperloop syntax
•Possibility of a module compatibility shim
