Strings to multiple files

DoktorBoshaft · Mar 08, 2006#12006-03-08T13:50+00:00

Hi, This might be a rather simple problem, but I am working on this huge binary data that contains nothing but scrambled, random data, except for a large number of "RIFF"-expressions. Something like this:

Code: Select all

...sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbfRIFFsdfsdfsdfhksjdf
hkjshdfkjshkjknsnmnmbfmsndbfsdfsdfsdfhksjdfhkjshdfkjs
hkjknsnmnmbfmsndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfms
ndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsn
dbfRIFFsdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbfsdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbfsdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbfsdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsndbfRIFF...

Now, all this data I would like to split into multiple files, each for one RIFF-string until the beginning of the next one:

...mbfmsndbfRIFFsdfsdfsdfhksjdf
hkjshdfkjshkjknsnmnmbfmsndbfsdfsdfsdfhksjdfhkjshdfkjs
hkjknsnmnmbfmsndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfms
ndbf
sdfsdfsdfhksjdfhkjshdfkjshkjknsnmnmbfmsn
dbfRIFFsdfsdfsdfhksj...

Each string should be saved as incremental numbered "#.at3"-files.

And I should probably mention that some of thse strings go as large as several MB, maybe that's the reason why I had problems creating my own macro if it.

Thanks.

Should I really help someone which forum name is Doktor Boshaft? Sorry, if your name is really Boshaft.

Your problem is very similar to that one at forum topic counter ?. You need the macro CountUp from this topic, too.

Your main macro is also similar. Below is the code for your main macro.

Note:
Trim trailing spaces before copying the 2 macros to the macro editor dialog because HTML adds a space at every line end which is bad for
".at3
RIFF"
where there should be no space after .at3.

And don't forget to enable the macro property Continue if a Find with Replace not found for your main macro.

Try to understand how your main macro works. I think, it's not too difficult.

Your main macro:

InsertMode
ColumnModeOff
HexOff
NewFile
Clipboard 9
"0"
StartSelect
Key LEFT ARROW
Cut
EndSelect
CloseFile NoSave
Top
Loop
Find MatchCase "RIFF"
IfNotFound
ExitLoop
EndIf
EndSelect
Key LEFT ARROW
Key RIGHT ARROW
StartSelect
Find MatchCase Select "RIFF"
IfSel
Key LEFT ARROW
Key LEFT ARROW
Key LEFT ARROW
Key LEFT ARROW
Clipboard 8
Copy
EndSelect
Key RIGHT ARROW
Key LEFT ARROW
NewFile
Paste
Top
".at3
RIFF"
Top
Clipboard 9
PlayMacro 1 "CountUp"
Key END
SelectToTop
Clipboard 8
Cut
Key DEL
SaveAs "^c"
CloseFile
Else
ExitLoop
EndIf
EndLoop
Clipboard 8
ClearClipboard
Clipboard 9
ClearClipboard
Clipboard 0

By the way: Is RIFF for Raster Image File Format? Hopefully your big file with multiple RIFF images does not contain 00 bytes because the macro works only in ASCII mode and not in HEX mode. If it contains 00 bytes, try to open the file in ASCII mode with checked option Allow editing of text files with HEX 00's without converting them to spaces at Configuration - Editor - Advanced. Well, I think, it's also possible to write a macro which does the splitting in HEX mode.

Heh, don't worry about the name. It may sound devious, but I'm a nice guy (or am I?).

Anyway, thanks. That halfway solved my problem, namely how to proceed with the macro. However, my big file indeed contains HEX 00-bytes, which adds to my problem.
No matter how many times I switch Allow editing of text files with HEX 00's on or off, or directly load the file instead of drag-dropping it, sometimes I'm able to manually copy any code from the big file including the 00-bytes from ASCII mode into another file, sometimes it replaces them with spaces or simply ignores what follows. The macro won't work with it either.

I'm sorta clueless here, any idea how to proceed or what settings I need to take precaution for?

Edit: Never mind, I found the solution by modifying the new file with

Code: Select all

NewFile
" "
SelectAll
HexOn
Paste 
HexOff

Thanks again though.

Aaahhh, switching to hex mode in the new file before pasting to avoid the conversion of the null bytes to spaces - very good idea. Even a macro profi can still learn something. Great, because I must not develop the splitting macro now for work completely in hex mode.
