kprintf

It is just my cross-plaform variant of printf. Unlike in standard printf, %l... and %ll... placeholders dont depend on size of long int and long long int. And you can change terminal colors by unix codes (\e[92m) even on Windows.

type	placeholder
i8 / i16 / i32	%i / %d
i64	%li / %ld / %lld / %lli
u8 / u16 / u32	%u
u64	%lu / %llu
f32 / f64	%f
char	%c
char[]	%s
void*	%p
32bit or less	%x
64bit	%lx

kprint

I don't really like printf function (and its variants), so i made safer and more convinient replacement.

function	returns	arguments
kprint	void/throw	kp_fmt, void*, kp_fmt, void*...
ksprint	Maybe<char*>	kp_fmt, void*, kp_fmt, void*...
kfprint	Maybe	FILE*, kp_fmt, void*, kp_fmt, void*...

how to use it:

• format construction:

  kp_fmt fmt= kp_fgColor | kp_bgColor | kp_dataFmt | flags | ktid;
  

  more about kp_fmt

  • fgColor and bgColor can be set to change console output color
  • you should set dataFormat for int/uint/float/char\* arguments and ktid for other types
  • flags can be set to modify TypeDescriptor.toString() behavior
  • don't forget to set TypeDescriptor.toString when registering type, or kprint will crash

• using base type arguments:
  you can just put them into a function

  kprint(kp_h|kp_upper|kp_prefix, 255);
  

  output: 0xFF

• using other registered types:
  should be sent as pointers

  Maybe m=MaybeNull;
  kprint(kp_fgBlue|kp_s, "Maybe: ", kp_fgGreen|ktid_MaybePtr, &m);
  

  output: Maybe: {value: { Pointer, 0x0 }}
