Files extractors scripting

[chrrox]

can you go to end of file and add x bytes to the end like "fatduck"
and then process the file like normal?
not another - option just something in bms script like what fatduck did with the end of file only adding some bytes to the end so it will recognize it as a file.

for the previous post of chrrox: uhmmm simple solution but it's not logical (because at that returned offset is not located the searched string) and still incompatible with the current findloc standard behaviour.

while for the current one: modifying the input file manually is definitely not a good solution (it's just not a solution at all, it can be defined a work-around)

[fatduck]

Is it possible to return a negative value rather then exit? eg: return -1 to the variable but not terminated the script! So we can at least do something to check and continue!

Another minor problem:

Code: Select all

set FName string "File_"
for i = 1 to 20
    set RES_NAME FName
    ...
    string RES_NAME += i
    log RES_NAME RES_START RES_OFFSET
next i

The i value is in Hexadecimal format! So the RES_NAME become:
File_1
File_2
...
File_9
File_0xa
File_0xb
File_0xc
...

Is it possible to export a decimal number?

[aluigi]

the value that I would assign to the destination variable is not found is "" so that it's enough to use the following example:

Code: Select all

findloc OFFSET string "FatduckFile"
if OFFSET == ""
    cleanexit # or anything else you want to do when the end of the file is reached
endif

but the problem is that the standard BMS language says that FindLoc must exit if the string is not found so the problem is differentiating the behavioiur of FindLoc keeping the compatibility with the standard command.
and idea could be a new command like FindLocX which returns "" instead of exiting but I don't know if it's a good idea to introduce a new custom command only for this thing.

[aluigi]

about FindLoc I have opted for the additional argument after the file number.
practically if you specify -1 after the filenumber that value will be assigned to the variable if the string is not found, example:

Code: Select all

FindLoc OFFSET string "FatduckFile" 0 "bad_luck_man"
if OFFSET == "bad_luck_man"
    cleanexit
endif

well it's a good compromise, so this is the solution available in the next version of quickbms

is it possible to make quickbms also for packing back ?

Here is an extractor for FEZ (fantasy earth Zero)

Code: Select all

get FILES long
get UNK long
for i = 0 < FILES
get NSIZE short
getdstring NAME NSIZE
get OFFSET long
get SIZE long

log NAME OFFSET SIZE
next i

this is a great archive format for som one to learn bms scripting from.
I attached a sample.
website http://tw.fez.gamania.com/
installer http://tw.dl.gamania.com/fez/FEZ_1103.exe
this game uses textures with wrong headers mainly dds and some tga and some kind of .mdl format.

[fatduck]

The new version work great! Thank you Bugtest!

How about decimal output as I said a few post above?

[aluigi]

ops I forgot that :)
uhmmm I could add an option for that (an option and not a command for not creating too much custom commands outside the BMS language).
practically internally quickbms converts all the numbers in 0xhexadecimal because it's more useful during scripts debugging so, yes, if necessary I can add an option which forces the myitoa() function to use the decimal notation.

oh I take the time also to say that I implemented some ways to add custom bytes (read "header") to the output files.
obviously it's not the most easy thing of the world just because it's not the job of the tool (something like a car which prepares the coffee) but works :)
the following is an example which builds a riff wave header in real time, like a raw_pcm to wav converter: http://aluigi.org/papers/bms/raw2wav.bms

the archive of that game is horrible, it's composed by various chunks but the PNTR one is not like the others... blah

@fatduck
I have just added the -D option which uses the decimal notation internally in quickbms so your doubt problem be solved.
