Hello, I would like to take this opportunity to announce the availability of an Adobe Shockwave Flash (SWF) library for Haskell: darcs get http://www.n-heptane.com/nhlab/repos/haskell-swf/ The library is a bit old and crufty, and it is not really release quality code. The cabal files are out of date, etc. But, I thought I would get it out there in case people wanted to play with it. (I have heard some noise on #haskell about it). It is primarily useful for compiling ActionScript assembly into a .swf file. If anyone is interested in improving the library, the most sensible starting places would be: 1) Update the code to use the new Binary library 2) Create a better API for creating assemble macros 3) Add support for the new Flash 9 action script virtual machine (AVM2). I currently implement 'macros' by defining a function like,
popArray :: [SwfAssembly] popArray = [ ActionPushFloat 0.0 -- Array.pop takes no arguments , ActionStackSwap , ActionPushString "pop" -- Call the pop() method , ActionCallMethod ]
And then using it like:
bindArg (STG.AtomVar var) = (ActionPushDuplicate : popArray ++ [ ActionPushString (escape var) , ActionGetVariable , ActionSetVariable ])
This is clearly, pretty lame. :) j. ps. I also have the beginnings of a YHC.Core -> SWF compiler. It can currently compile this simple program:
main = case id (Just 'a') of (Just c) -> displayPrimitive c Nothing -> displayPrimitive 'f'
Unfortunately, it does not yet implement garbage collecting, updates, proper environment saving, and other essential features. It also generates some pretty inefficient code. I am going to try to get the current version 'working', and then do a better implementation based on everything I learned from my first attempt at a Haskell compiler. I should note that this is different than the Haskell -> Javascript compiler that is already in YHC. I am targeting the flash virtual machine byte-code directly, not the higher level actionscript (aka, ecmascript) code. I pushed what I currently have at: http://www.n-heptane.com/nhlab/repos/yhc/ the code is in the directory: http://www.n-heptane.com/nhlab/repos/yhc/src/translator/avm2/ First build yhc normally, then cd into that directory and run make. Hopefully that will work for you.
