kprintf

It is just my variant of printf.

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	kprint_format, void*, kprint_format, void*...
ksprint	Maybe<char*>	kprint_format, void*, kprint_format, void*...
kfprint	Maybe	FILE*, kprint_format, void*, kprint_format, void*...

how to use it:

• format construction:

  kprint_format fmt= kprint_fgColor | kprint_bgColor | kprint_fdataFmt | flags | ktid;
  

  more about kprint_format

  • 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(kprint_fmtHex | kprint_fmtUppercase | kprint_fmtWithPrefix, 255);
  

  output: 0xFF

• using other registered types:
  should be sent as pointers

  Maybe m=MaybeNull;
  kprint(kprint_fgBlue | kprint_fmtString, "Maybe: ", kprint_fgGreen | ktid_MaybePtr, &m);
  

  output: Maybe: {value={0, ktid_Null}}
