FFI

A TypeScript source can have FFI meta-data attached to it. Here is an example:

program.ts

export declare class C {
    public x: number;

    public static f(): void;
}

program.ffi.json

{
    "C": {"actionscript": "q.b::C"},
    "foo.C": {"actionscript": "q.b::C2"},
    "C.f": {},
    "C#x": {}
}

C.f means f property from C and C#x means x instance property from C. q.b::C is C in the public namespace of the package q.b.

The "actionscript" property is used to map a TypeScript class to an existing ActionScript class.
