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。
0 z2 C4 j8 e0 ^0 C/ I$ o; \, n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.
2 ]7 n: p) ?( Y; uobviously 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.
4 u5 g) T# `$ U* |, M- Sthen the input BMS script no longer needs the semicolon ';' and the file number which are now optional. ' Q" o: ] _" |5 G+ Z
: z. s7 v3 @/ h' f0 S: ~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.

about the new commands, the following is an example of BMS script for the game Outcry (you can call it outcry.bms or outcry.txt or as you want):

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. ) n1 ] A' t8 h( l5 l8 j

4 ^: o9 a# [; P: q$ w! {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:
( l3 J& w* H4 G4 f7 ]- N k& J2 e1 T+ d% B7 r
Code:get OFFSET asize - U n. v) T+ w- S3 Z0 P6 C. z

..."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. w5 t! n4 J0 ~2 w3 r
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. ! y: ^, o% E! c& C
