libps2_printf

A library/wrapper created by myself inspired on ps2_drivers by fjtrujy that makes easy to print on the screen with one declaration without any burrocracy, it´s gonna be using firstly on doomgeneric-ps2 and Wolf4SDL

History

When i was trying to upgrade the dooomgeneric-ps2 by Arawn-Davies Arawn was having difficult to make the scr_printf work yesterday. so i decided to implement a wraaper(initially) and when it worked i felt realized so, i thinked to work more on this and this makes the libps2_printf surges.

Installation

Install ps2dev and his whole package and then: $ make install to get the library running.

to link the library just copy and past this on the Makefile EE_LIBS += -lps2_printf -ldebug

Comparison and example

Let me put an example based on the helloworld sample, which we will compare Before vs After to see how easy this library can be.

BEFORE

Makefile

EE_LIBS += -ldebug -lc

main.c

#include <stdio.h>
#include <tamtypes.h>
#include <sifrpc.h>
#include <debug.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
  SifInitRpc(0);
  init_scr();

  scr_printf("Hello, World!\n");

  // After 5 seconds, clear the screen.
  sleep(5);
  scr_clear();

  // Move cursor to 20, 20
  scr_setXY(20, 20);
  scr_printf("Hello Again, World!\n");

  sleep(10);

  return 0;
}

AFTER

Makefile

LIBS += -lps2_printf -ldebug -lc

main.c

#include <ps2_printf.h>
#include <sifppc.h>
int main(int argc, char *argv[])
{
  SifInitRpc(0);
  //Print the screen and then after 5 seconds clear the screen.
  ps2_printf("Hello, World!\n", 5);

  // Prints the screen once again but move the cursor to 20 20
  // after 10 seconds
  ps2_printf_XY("Hello again, World\n", 10, 20, 20);

  return 0;
}

beautiful isn´t it?
