Announcing: RABCDAsm
RABCDAsm (Robust ABC (ActionScript Bytecode) [Dis-]Assembler) is a collection of utilities including an ActionScript 3 assembler/disassembler, and a few tools to manipulate SWF files.
This package was created due to lack of similar software out there.
Particularly, I needed an utility which would allow me to edit ActionScript 3 bytecode (used in Flash 9 and newer) with the following properties:
- Speed. Less waiting means more productivity.

can assemble large projects (>200000 LOC) in under a second on modern machines. - Comfortably-editable output. Each class is decompiled to its own file, with files arranged in subdirectories representing the package hierarchy. Class files are

d from the main file. - Most importantly – robustness! If the Adobe AVM can load and run the file, then it must be editable – no matter if the file is obfuscated or otherwise mutilated to prevent reverse-engineering. RABCDAsm achieves this by using a textual representation closer to the ABC file format, rather than to what an ActionScript compiler would generate.
