abcsx - The ActionScript Byte Code assembler / disassembler in Scheme

This is a set of tools to examine Adobe's ABC format file.

* Usage

abcsx.ss filename.sx

Generate ABC binary file from ASM-form or ABC-form (described
below). The output file name is filename.sx.abc.

abcsx.ss -dump [-abc] filename.abc

Desassemble an abc file. The output is printed to stdout. If -abc
option is specified, ABC-form (described below) is chosen.

runasm.sh filename.sx

Assemble ASM-form or ABC-form and execute it by avmshell. It requires
avmshell installed. Avmshell is included in Tamarin VM's source tree.

swf_abc.erl width height classname abcfile.abc

An helper program to generate a flash file from an abc file. It
requires Erlang.

* File Format

There are two kinds of representation to describe a ABC file. You can
use either way depend on the purpose. Asm.ss accepts both format.

ASM-form : A (relatively) human friendly notation

(asm
 (method
  (((signature
     ((return_type *) (param_type ()) (name "hello") (flags 0) (options ()) (param_names ())))
    (code
     ((getlocal 0)
      (pushscope)
      (findpropstrict ((package "") "print"))
      (pushstring "Hello, World!!")
      (callproperty ((package "") "print") 1)
      (returnvoid))))))
 (script (((init (method 0)) (trait ())))))

ABC-form : One-to-One translation to S-expression

(abc
 (minor_version 16)
 (major_version 46)
 (constant_pool
  ((integer ())
   (uinteger ())
   (double ())
   (string ("hello" "" "print" "Hello, World!!"))
   (namespace ((package (string 2))))
   (ns_set ())
   (multiname (((namespace 1) (string 3))))))
 (method
  (((return_type (multiname 0)) (param_type ()) (name (string 1)) (flags 0) (options ()) (param_names ()))))
 (metadata ())
 (instance ())
 (class ())
 (script (((init (method 0)) (trait ()))))
 (method_body
  (((method 0) (max_stack 2) (local_count 1) (init_scope_depth 0) (max_scope_depth 1) (code
     ((getlocal 0)
      (pushscope)
      (findpropstrict (multiname 1))
      (pushstring (string 4))
      (callproperty (multiname 1) 1)
      (returnvoid)))
    (exception ())
    (trait ())))))
