Type "Hello, World!"

11

2

Write a program which generates keyboard events which type Hello, World!.

It doesn't have to be platform-independent.

It can't leave any keys pressed. For example, in Java, Robot.KeyPress('H'); will leave H pressed, so you must release it with Robot.KeyRelease('H');

You may assume that the caps lock is off when your program is run. Capital letters can be typed either by holding shift and pressing the letter, or by toggling caps lock. For the !, you'll probably have to use the shift method.

Shortest code wins.

C (Linux), 186 bytes

#include<sys/ioctl.h>
#include<fcntl.h>
#include<stdio.h>
main(){char*s="Hello, World!",d[99],*c;fscanf(popen("tty","r"),"%s",d);int D=open(d,O_RDWR);for(c=s;*c;c++)ioctl(D,TIOCSTI,c);}

After applying ugoren's suggestions:

111 bytes

main(D){char*c,d[99];fscanf(popen("tty","r"),"%s",d);D=open(d,2);for(c="Hello, World!";*c;)ioctl(D,21522,c++);}

You can shorten some. Remove s (just initialize for(c="H..), increment c in the ioctl, main(D) to save int. Maybe also remove some includes (even hard-code O_RDWR and TIOCSTI). – ugoren – 2013-02-25T14:44:32.150

@ugoren Thanks, I'll try them :) – saeedn – 2013-02-26T00:44:57.600

This one is not the shortest. Why is this the accepted answer? (I think it is a nice answer, but I just want to learn how the site works.) – 11684 – 2013-03-11T12:56:33.633

@11684 The author of the shortest answer asked me not to count it, so I accepted the shortest non-trivial answer instead. – cardboard_box – 2013-03-11T23:44:23.620

No need to call tty it only works if stdin is a tty, in which case, 0 is already an open terminal fd. – Dave – 2013-12-09T08:38:20.713

3Huh. Looks like you chose the right language for the right job. – cardboard_box – 2013-02-23T02:18:53.583

You can shorten it to tell app"System Events"to keystroke"Hello, World!". – marinus – 2013-02-25T05:01:02.413

Damnit, I thought of this independently... +1! – 11684 – 2013-03-11T12:54:37.613

send Hello, World{!}

Please don't count this one. I don't want to cheat out people who have actually done this with a language not meant for sending keystrokes. This answer is just for completion :P
