Well this is what I have up to this point.
Some missing semi colons, maybe some other stuff. But the recursion on
expressions, binary and unary operators are working great.
Got anonymous functions, getters, setters, try etc. working. Will have
to be schooled on the use of 'this' and other things but the design is
so mutable we could even implement more than one type of cross compile
as easy as I just made this new one for the closure compiler.
How do we want default arguments dealt with on functions?
Honestly I don't know exactly how ActionScript is supposed to
translate to JavaScript on somethings. I have namespaces and stuff
like that working but obviously it doesn't have a js counterpart.
Erik! I need your table erm.. javascript bible for a reference of what
we need to test against.
Ah, the beauty of this new design is we can unit test each part of the
expression, statement conversion from as -> js! This part is so
exciting, we will know down to the binary, unary expression if the js
code is getting output correct.
Erik, you will have to get me a comprehensive list for comment and
type hint locations as well.
Well that's it for me for now.

Quoting Michael Schmalle <apa...@teotigraphix.com>:
Hi,
Seeing as winter is here in NewHampshire and ice covers the ground,
I used the opportunity to put my money where my mouth is;
NOTE: All the javascript is generated by code I wrote using the
AST/Visitor/Walker pattern of the node hierarchy and their
corresponding definitions. I have it running from the command line
like MXMLC does.
I about 10 hours of programing I have the following constructs cross
compiling to JS using Flacon.
I will say, Falcon is one of the best designed APIs I have used in a
long time. Whoever architected this compiler gets a huge pat on the
back from me.
Right now this is hoisted ontop of MXMLC as a quasi target compiler.
Oh how I love prototypes. I cannot believe I actually have this
working in less than two days.
As far as code, it will be in my whiteboard when it's in my
whiteboard. :) Whenever that is, no specific time.
The amount of ridiculousness I felt trying to wade through the
FlaconJS code prompted me to do this.
The thing I really grabbed on to is we are using the closure
compiler so worrying about highly optimized cross compiler becomes a
non issue. Quote Erik on this.
Peace,
Mike
