Demo Details

A demoable version that allows you to select a flickr photo feed, scale the images in real time, and drag photos you wish to keep into a tray.

Tasks

Note: this page has not yet been reconciled with any tasks the SWF9 Target or DHTML_Target pages.

[edit]

Server

  • Add wrapper page that includes OLR and lzt=js script includes (LPP-1304) [Max]
  • Add request type (lzt=js?) that emits javascript from lzc --script (LPP-1305) [Henry]
[edit]

Build System

(reduces integration overhead between lps-dev and lps-legals if done early)

    • Move mini runtime from sandbox to lps/includes/lfc (| LPP-1299)[Max]
    • Migrate .as files to .js (LPP-1300) [Max]
      • lps-legals -> lps-dev or the other way around?
      • Holding off until move to svn
    • move ORL out of WEB-INF (LPP-1300) [Max]
      • Instead, could build DHTML OLR outside WEB-INF
[edit]

Compiler

  • Add runtime type (lzr=dhtml) for conditionalizing ORL builds and server actions (LPP-1324) [Max/Tucker]
  • Compile resource tags to script (LPP-1325) [Henry]
    • responsible for assembling multiframe resources
    • Should provide a list of relative URLs for each resource declaration, keyed off server-assigned library names
    • LzLibrary = {}; LzLibrary.$resname = ['url','url2'];
    • Could preload resources
  • Emit constraints as ECMA instead of bytecode (LPP-1302) [Tucker/Oliver]
    • convert new constructor(parent, args) -> LzFactory.create(constructor, parent, args) (LPP-1303)[Tucker]
      • may want to copy n constructor arguments instead of just 2 (parent, args)
    • convert .super.foo(args) -> .callInherited('foo', args) [Done according to Tucker]
    • Pass list of events to runtime (LPP-1326)[[Tucker]
      • events need to be created ahead of time - can't rely on onxxx failing silently as in flash
      • e.g. DeclareEvent( LzFactory, 'oncreate' );
      • should this be a runtime task based on a list of events?
    • clean ECMA4~ frontend
    • multi-target backend
      • AS3
        • (ECMA4~ to AS3 transform) LPP-1358 Tucker

      • DHTML (JS1.6)
        • ECMA4~ to ECMA3+ transform LPP-1360 Tucker
      • AS2
        • ECMA4~ to ECMA3 (to AS2) transform LPP-1361 Tucker
        • AS2 to SWF6-8 backend LPP-1362 Tucker
        • E4X to XML API transform LPP-1363 Tucker

    • AS3 runtime (LPP-1373 max)
[edit]

ORL

    • Include prototype AJAX library and have dataset instantiate/load from it [Henry]
    • Remove flasm, make sure it's in sync with bytecode in lps-dev (LPP-350) [Jim]

    • update ORL generic to ECMA4~ (LPP-1419)[max]
    • DHTML kernel
      • implement display node (LPP-1420)[Henry]
      • multiframe resources (LPP-1421) [Max]

[edit]

Research

    • investigate AS3 Sprite API [Max]
    • Investigate Flash CSS runtime support/APIs [Elliot]
    • MiniLFC: Why does style.backgroundColor only work if the div has contents?
    • LZX stress test (10, 100, 1000 animated views with resources) timed in dhtml, flash
[edit]

Notes

  • ECMA4~ here means ECMA3 + whatever we need from ECMA4
    • at least: class keyword, sealed decl, type decls, E4X, compound attrs
    • not this time: packages, namespaces
  • ECMA3+ is ECMA3 + E4X
  • "DHTML" here is XHTML + DOM2 + CSS2 + maybe canvas/whatwg
  • when is IE7 going to be released? Will Jscript.NET support ECMA4~ features by then?
[edit]

Notes

  • Stages are currently milestone-driven, not resource-driven.
  • components work may need to move earlier than Stage 3
  • E4X and regexp available to cut if necessary (prefer E4X)
  • DHTML work after Stage 1 to scale with available resources
  • risk: AS3 compiler, runtime and kernel not complete until Stage 3
