最近老外开发了一个很不错的通用命令行解包器，以后制作解包器只要简单的写几句脚本就行了。 8 s t; B' @" ~1 y1 I
现在老外还在不断完善之中，有兴趣的朋友来测试一下吧。

well I have some good news.

I have made it compatible with the BMS scripting language so people don't need to learn 1000 languages and then it's a good language. # }: v( r* o0 b0 d& e: a! ?! s
obviously the BMS support has been enhanced so it's possible to use XOR, rot13, zlib/deflate, lzo, lzss plus various new operator in the "math" command (and, or, xor, complement, not, shift and modulus) and some other things like choosing the desired endianness.
+ V6 N s- h+ t& Wthen the input BMS script no longer needs the semicolon ';' and the file number which are now optional.

note that the BMS guide available on http://wiki.xentax.com/index.php/BMS doesn't report some additional fields which instead already exists like the GetCT, ComType and ReverseLong or some internals variables like EXTRCNT so I have tried to find and add also these ones.

obviously it needs to be tested more because 2 days are not enough for a project like this which is not so basic so anyone is invited to test it and suggest new features. 1 u" B' L' ?5 h, [) t* }' _

if you know the size of the structure or where is located the particular value you are searching (for example some file formats have a 32bit number in the last 4 bytes which has the offset where are located the other file structures) you could use something like the following:
% m% Q- b0 Z( i6 }, D' T
, X; e6 [$ U9 Q9 uCode:get OFFSET asize % Q' H- ?* y$ o% U- R
math OFFSET -= 4
: D2 A9 n a5 ^goto OFFSET 3 g! Y6 `/ d5 J5 ?/ k: `! D
get OFFSET long
: ~. E+ X' |9 S3 l5 Mgoto OFFSET
6 f5 E: q j, S k8 f..."asize" is not available in the BMS guide but is supported by both multiex and my tool, it contains the total size of the file. ' |& {, a" @7 o; [
anyway tell me a file format which has the file name table at the end, it's good to make various exercises for testing the BMS language and where is possible to enhance it. . h1 y! V/ k3 c1 q) a
