How do you use match to split at a .

Example using :

Code:

macro doCall param 
{ 
        match library:proc,param 

        etc etc ......
}


doCall kernel32:ExitProcess

Works because : is a symbol character, library and proc are separated Smile

Code:

macro doCall param 
{ 
        match library.proc,param 

        etc etc ......
}


doCall kernel32.ExitProcess

Does not work. I've reread the docs, looked at include file all over the place, but still can't work it out Sad

"." is normal character, just like any of a-z, A-Z, 0-9. That would be same as trying to split "kernel32xExitProcess"

Below, doCall1 prints out "kernel32 ExitProcess" because : is a symbol character, but as you say . is not a symbol character, it's a normal character. So what is the syntax to achieve the same print out with doCall2 using a non symbol character like a dot?

Clearly it must be easy but it seems I'm to stupid to work it out Sad

Code:

macro doCall1 param 
{ 
        match library:proc, param 
        \{
                display \`library, ' ', \`proc, 13,10
        \}
}

macro doCall2 param 
{ 
        match library.proc, param 
        \{
                display \`library, ' ', \`proc
        \}
}


doCall1 kernel32:ExitProcess
doCall2 kernel32.ExitProcess

output:

doCall1 = kernel32 ExitProcess
doCall2 = library proc <-- wrong

none. think of the problem, as if you would want "x" to become separator. for example "doCall2" would have to split "abcxyz" to "abc" and "yz". It is exactly same problem as with ".". There is no (normal) solution i know to that.

So there is no solution Shocked

Seems strange to be able to concat a string but not split it. Oh well, thanks for the reply.

Does anyone have a complicated macro way of doing this?

MichaelH: thing about "`", "load" and "store". that is the ugly way.

Is it possible to parse GUID string {XXXXXXXX-XXXX-XXXX-XXXXXXXXXX} into GUID struct using "match" keyword? How to split last XXXXXXXXXX into db 0XXh,0XXh,0XXh,0XXh,0XXh,0XXh,0XXh,0XXh,0XXh,0XXh ?

afw2004: i am afraid, you will need ugly `/load/store tricks again. If the number would fit into dq, it would be much easier.

Have you seen the GUID macro in the USECOM example in standard Win32 package?

Tomasz since match already can separated using symbol characters, would it be out of the question to have match be able to split a string with non symbol characters or is that just too difficult?

split is a very powerful function in javascript and having it in fasm macros would to great if it could be done.

I agree that this would be an useful addition to preprocessor, however I really don't understand the reference to JavaScript. Wink

Yes, you are right, sorry Smile

Given what you still have to achieve with a debug format for fasm etc, I suspect this idea will not happen for some time?
