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。

yesterday and today I have worked on the script parser and the results are so good that my beta version already works. " D7 @% [( T: a" s5 w) @$ I
" q, T3 t6 E% P
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. 8 C' t" r. P# F! \$ h. _* 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. 8 b r- m0 z" B2 p0 I8 i
then the input BMS script no longer needs the semicolon ';' and the file number which are now optional. : q3 \9 L7 S3 {) v$ e3 J1 L
/ X; O" ~9 _. K' q7 ?# n
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.

r1 q9 d7 r0 }. {% [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:
, h- u4 Q# w- e
7 R) h) t, I: @) TCode:get OFFSET asize
( e+ j: D; ?, L D$ u" R B" [math OFFSET -= 4 5 q9 [* \1 j6 B, ^5 n
goto OFFSET
' P$ W+ Z9 k+ Y: @# v: U8 hget OFFSET long 0 f$ A8 h: T+ F& w" W" ^4 o
goto OFFSET 4 {, c- Y. U, O4 S& G
..."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. ' P) y; \9 b, F ?* D4 I
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.
