I'm still working on a new Forth implementation... Forth has a word `key` that gets one character from stdin. It shouldn't wait for a newline to get the character. Is there any way to implement this currently in PIR?
`$S0 = read 1` waits for the newline. If you turn off buffering for stdin: $P0 = getstdin stdin."setbuf"(0) $S0 = read 1 Parrot still waits for the newline, but the remaning characters aren't picked up. So if you type "hello world\n" Parrot will take the "h" and your console will get "ello world\n". If it's not possible right now, I think it should be. The Forth implementation needs it (though it's not exactly one of the target languages). And I know people often want/expect Perl's getc to do the same (I did -- and I see the question come up at Perl Monks occasionally). I don't how much work it'd take either, not knowing much C myself. It looks like maybe it requires `getch` from conio.h (ported from DOS) or curses (which I know dan is fond of ;)? And given the cross-platform requirements of Parrot... is this even possible? -- matt
