Custom printf - Tr1viUm - 03.12.2009

Hello!

I've been trying to make my own printf function that only gets called if debug mode is on. I however can't get them working with strings in it. I made them for integers and floats though but that's useless for me. I tried using getarg to use it at printf.

I read about making a #define to bypass this problem. It didn't work with the state machines at me. I'm not sure if it's even possible what I want but perhaps anyone knows more?

My code:
Код:
sprintf(const format[], {Float,_}:...) <debug:on>
{
	printf(format, getarg(1));
}

You mean something like this?

pawn Код:
new
    FALSE = 0;
pawn Код:
#define ConsoleMsg(%0,%1) \
do \
{ \
  new \
      string[128]; \
  if(strlen(%0) > 0) \
  { \
    format(string, sizeof(string), %0, %1); \
    print(string); \
  } \
} \
while(FALSE)

No, that does not support the state machine (<debugn>).

I use this code for a custom print function. I need one that formats the print too.

pawn Код:
sprint(const string[]) <debug:on>
{
    print(string);
}

pawn Код:
#define DEBUG
pawn Код:
#if defined DEBUG
    #define debug(%1) printf(%1)
#else
    stock asd() { }
    #define debug(%1) asd()
#endif
Use debug() as printf() and when you don't want the debug messages coming up, simply comment out #define DEBUG.

Sorry for not mentioning it but I'm using a /debug command to put it on and off.

I suppose you meant printf(string); to be print(string);.

I was reading Code Optimisations before I posted this and as you said there is no solution yet.

Only remaining 'solution' is defines then.

Thanks for the help.

Yes, edited.
