printf.exe: Arithmetic and Programming

[Aacini]

I included \e as escaped char for ESC and enabled Virtual Terminal Processing mode in a new printf.exe version. I did a small test via

Code: Select all

printf "\e[104;93mbright yellow on bright blue\e[0m\n"

and works correctly. However, I also tried

Code: Select all

printf "\e#3Double Height (implies Double Width)\n\e#4Double Height (implies Double Width)\n"

and the font don't change. I suppose that the ESC#3 and ESC#4 change font sequences works only in Windows 11 (I have Windows 10).

Thanks a lot for the Compiler Explorer link to the change console mode code. However, the assembler code shown there is somewhat convoluted... The way I write assembler code is simpler and more direct, similar to C code. Look it by yourself:

Code: Select all

        invoke  GetStdHandle, STD_OUTPUT_HANDLE         ;EAX = console handle
        mov     hOutput, eax                            ;store it
        ;
        invoke  GetConsoleMode, hOutput, ADDR dwVariable;get console mode in dwVariable, EAX = 0 if fail
        test    eax, eax                                ;fail?
        jz      SHORT @F                                ;yes: jump
        ;
        or      dwVariable, ENABLE_VIRTUAL_TERMINAL_PROCESSING OR DISABLE_NEWLINE_AUTO_RETURN   ;change mode
        invoke  SetConsoleMode, hOutput, dwVariable     ;enable process of VT100 terminal sequences
        ;

That's great.

I suppose that the ESC#3 and ESC#4 change font sequences works only in Windows 11 (I have Windows 10).

Unfortunately that seems to be the case. This is how it looks like in a Win 11 console.

Oh wow I didn't expect that libraries would define so many things that make writing assembly code as comfortable as in your snippet. (And it proves how little I know about assembler )
