I have an archive where data is stored like nodes, for each compressed file in this archive, there is a node-header, saying what kind of data it is. I want to log these compressed files' filename depending on the node type. So a file with the type of "TEX0", would have the extension ".gtx" and so on.

Here's the script I made for the archive.

idstring "ANP 151 "
endian big
get FILES long
get NAMESZ long

for i = 0 < FILES
   getdstring NODE 4
   goto 12 SEEK_CUR
   
   # this is where you do the node name parsing
   
   getdstring NAME NAMESZ
   get OFFSET longlong
   get SIZE longlong
   log NAME OFFSET SIZE
next i

Heres the archive too.
I don't know why I can't attach an archive, but I renamed it from ".anp" to ".txt", so I could upload it.

Unfortunately there is no "switch/case"-like command in quickbms therefore the long sequence of "if/elif/else/endif" is the only option.

There are alternatives like storing the magic value and the relative in two arrays... but the script will look quite messy.

In my opinion the bestt alternative is storing the long list of "magic:extension;" in a MEMORY_FILE and searching them:

set MEMORY_FILE string "TEX0:gxt;TEXT:txt;BLAH:blah;"

# read the magic
getdstring MAGIC 4

# search the magic
string MAGIC + ":"
goto 0 MEMORY_FILE
findloc POS binary MAGIC MEMORY_FILE ""

# set the extension
if POS == ""
    set EXT string "dat"
else
    math POS + 5
    goto POS MEMORY_FILE
    getct EXT string ';' MEMORY_FILE
endif

print "Extension: %EXT%"
