The kaustic lab __ http://compiler.kaustic.net/lab ActionScript / Flex / Flash / AIR / Processing Tue, 24 Aug 2010 06:45:36 +0000 http://wordpress.org/?v=2.3.2 en Flash 10.1 avmplus.* http://compiler.kaustic.net/lab/?p=49 http://compiler.kaustic.net/lab/?p=49#comments Mon, 23 Aug 2010 19:17:43 +0000 Jan http://compiler.kaustic.net/lab/?p=49 If you introspect the Flash 10.1 playerglobal.swc (in Flash Builder for example) you will notice a package that was not there in Flash Player 10, namely avmplus.

The interesting part is that it contains a method describeTypeJSON(*, uint):Object (which is an internal function)
The first parameter is the object to describe and the second is a flags parameter (defined as uint constants in the very same package).

HIDE_NSURI_METHODS = 1
INCLUDE_BASES = 2
INCLUDE_INTERFACES = 4
INCLUDE_VARIABLES = 8
INCLUDE_ACCESSORS = 16
INCLUDE_METHODS = 32
INCLUDE_METADATA = 64
INCLUDE_CONSTRUCTOR = 128
INCLUDE_TRAITS = 256
USE_ITRAITS = 512
HIDE_OBJECT = 1024
FLASH10_FLAGS = 1535

By doing a little monkey-patch-hacking (creating something in the same package so that it can access the internals), it is possible to expose this method for all yer class inspection purposes… *grin*

Example:

package avmplus
{
    public function getInterfaces(object:*):Array
    {
        return describeTypeJSON(object, INCLUDE_TRAITS | INCLUDE_INTERFACES).traits.interfaces;
    }
}

Update August 24th 2010: Till Schneidereit’s in-depth article on the subject.

If you’re lucky you get away with running copylocale, but i always stumble upon nastier stuff (most projects for Belgian clients are bi-lingual… erm… bi-local French/Dutch).

To solve this for once and for all i wanted to create an elegant ANT scripty that takes care of all my localisation woes… Something easy, as it should be (c).
Thus i embarked on a (somewhat boring i must admit) adventure and started from the article “Easily compile resource bundles using Ant” which i improved a little here and there (uses compc.jar and not flexTasks, dynamically composes the -include-resource-bundles argument etc…) and did get some gratification i’d like to share.

Thou can download the project here.

Configuration:
- edit build.xml and change the FLEX_HOME property if needed
- that’s it… the rest is automagically done for you… no locales or bundles to specify…

Workflow:

Explode existing resource bundles
- place .swc files under /src/main/resources/locale/{locale}/..
- run ANT build script, target “explode-overwrite”

Compile resource bundles to swc or swf
- place .properties files under /src/main/locale/{locale}/{bundle}/..
- run ANT build script, target “compile-swc” (default) or target “compile-swf” (for runtime resource loading)

Example:
- copy the SDK compiled resource bundles under /src/main/resources/locale/en_US
- run the “explore-overwrite” target
- adapt the files under /src/main/locale/en_US to your liking + rename the en_US folder to your locale
- run the “compile-swc” target

Et voilà! Happy multilingual times verdekke nondedju.

With Cairngorm and PureMVC projects, i often see mock Delegates or Proxies appear (and some kind of injection). What i do most of the time is write the service implementation as an Interface and mock there instead of in the Proxy (PureMVC) or mock the ServiceLocator (Cairngorm) by using (in the case of Remoting) MockRemoteObjects.

Mims online as the “Atari Punk Console“, that name and circuit got a life on it’s own.

And now here’s the Flash software synth version in glorious pre-alpha rough fashion (Flash Player 10 required)!

I’ve got some ideas to turn this into something… stay tuned…

New features? Plenty… One of them is real-time, dynamic audio processing. That’s right ladies and genetals! We’re talking synths and effects in Flash here!

This is so much fun, here’s one experiment (requires the Flash Player 10 and is loading a remix i’ll never finish…)

A big cheers to Tinic, Joa and Andre!
