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。

well I have some good news.
2 J4 P6 p0 H t: T$ I+ a$ ~yesterday and today I have worked on the script parser and the results are so good that my beta version already works.

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 G/ E [, [: j$ f: }
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.

& ?' m4 T6 X% L9 a! y9 a7 A, Z, f, h, _' V' [
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. ( q! N. u( Y2 h8 M! A

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:
8 y( I, ?* u3 m8 w; m8 O% d* J0 ~% n& L
Code:get OFFSET asize - Q( D4 r6 r3 Q; N! `, w/ u3 J
math OFFSET -= 4
- Z: `- l9 K! a/ rgoto OFFSET 8 z; Q1 |7 ^8 I5 s
get OFFSET long + e# m, e' W; y( M0 |$ e
goto OFFSET 8 v+ W1 k* S! u' E7 J) c" L
..."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. ( N% o: i! }* L$ L6 E3 j+ ^( @/ s
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. 3 O6 B2 _5 X( B% S
