NAME

6       flasm - A swf bytecode assembler/disassembler
7

SYNOPSIS

9       flasm [-daubzx] filename
10

OPTIONS

12       -d  Disassemble the given SWF file to the console
13
14       -a  Assemble the given flasm project
15
16       -u  Update SWF, replace flasm macros
17
18       -b  generate __bytecode__ instruction or byte sequence
19
20       -z  ompress SWF with Zlib
21
22       -x  Decompress SWF
23

EXAMPLES

25       flasm -d foo.swf
26
27       Disassemble foo.swf to the console. To see action offsets in disassem‐
28       bly set showoffset and hexoffset options in flasm.ini.
29
30       flasm -d foo.swf > foo.flm
31
32       Disassemble foo.swf, redirect the output to foo.flm. Alternatively you
33       can simply call flasm without command: flasm foo.swf creates foo.flm in
34       the same directory.
35
36       flasm -a foo.flm
37
38       Assemble foo.flm and update the SWF defined inside.  The backup of
39       original SWF is created with .$wf extension.
40
41       flasm -u foo.swf
42
43       Disassemble foo.swf to the temporary file.  Execute flasm macros embed‐
44       ded in SWF.  Make trivial optimizations automatically: remove double
45       nots, replace 0.0 with 0, rebuild constant pools, clear register argu‐
46       ments.  Create .$wf backup, update the original SWF.
47
48       It's a good idea to update the final version of SWF with flasm -u.
49       Don't expect the SWF to be noticeably faster, it will just make it a
50       bit smaller.
51
52       flasm -b foo.txt
53
54       produce __bytecode__ instruction or byte sequence, depending on boutput
55       setting in flasm.ini.  Takes as input a simple action list without any
56       movie or frame declarations.  Output is sent to console.  Redirect it
57       to file if you wish: flasm -b foo.txt > foo.as When boutput is set to
58       1, Flasm produces binary output
59
60       flasm -x foo.swf
61
62       Decompress foo.swf, create .$wf backup.
63
64       flasm -z foo.swf
65
66       Compress foo.swf, create .$wf backup. Source SWF doesn't have to be
67       Flash MX/MX 2004 file. However, only Flash MX/MX 2004 player will be
68       able to play the resulting compressed file.
69
70       flasm settings are read from flasm.ini. There aren't many of them, and
71       they are commented. You may, for example, switch bytecode offsets on
72       and off there.

DESCRIPTION

75       flasm disassembles your entire SWF including all the timelines and
76       events.  Looking at disassembly, you learn how the Flash compiler
77       works, which improves your ActionScript skills.  You can also do some
78       optimizations on the disassembled code by hand or adjust the code as
79       you wish.  flasm then applies your changes to the original SWF, replac‐
80       ing original actions.
81
82       It's also possible to embed flasm actions in your ActionScript, making
83       optimizing of large projects more comfortable.  flasm is not a decom‐
84       piler. What you get is the human readable representation of SWF byte‐
85       codes, not ActionScript source.  If you're looking for a decompiler,
86       Flare may suit your needs. However, Flare can't alter the SWF.
