[9fans] The first annual "Hello, World" challenge

Well, they just seem to keep getting longer.

Your goal: hello, world in one line. Language of your choice. Linking
in a 512 MB library is a violation of the spirit of this contest.

Additional rules:
- line length is not defined but let's be reasonable
- if you can fit it in a standard Hollerith card format (72 chars plus
8 chars of comment) that's a plus

Redirection of stdout is allowed.

In rc:
% window 'echo hello world; sleep 5'

It's probably against the spirit, but hey, it fits on a Hollerith
card! Technically.

In C, the quickest thing I came up with using draw is:
#include <u.h>
#include <libc.h>
#include <draw.h>

void
main(void)
{
	initdraw(0, 0, "hello");

	string(screen, addpt(Pt(40,40), screen->r.min), display->black, ZP,
display->defaultfont, "hello world");
	flushimage(display, 1);
	sleep(5000);
}

If you throw in libpanel, it's only a little bigger (mostly libpanel
maintenance things) plus you get a button to quit:

#include <u.h>
#include <libc.h>
#include <draw.h>
#include <event.h>
#include <panel.h>

Panel *root;

void
done(Panel *p, int buttons) {
	USED(p, buttons);
	exits(0);
}

void eresized(int new)
{
	Rectangle r;

	if(new && getwindow(display, Refnone) == -1) {
		fprint(2, "getwindow: %r\n");
		exits("getwindow");
	}
	r = screen->r;
	plpack(root, r);
	draw(screen, r, display->white, 0, ZP);
	pldraw(root, screen);
}

void
main(void)
{
	Event e;

	initdraw(0, 0, "hello");
	einit(Emouse);
	plinit(screen->depth);
	root=plframe(0, EXPAND);
		pllabel(root, PACKN|FILLX, "Hello world!");
		plbutton(root, PACKN, "Done", done);

	eresized(0);

	for (;;) {
		switch(event(&e)){
		case Emouse:
			plmouse(root, e.mouse);
			break;
		}
	}
}

would troff be cheating?  it's a language.
	hello, world
if it is, how about in rc
	echo hello, world
sed
	s/^/hello, world/g
dc
	[hello, world]p
awk
	BEGIN{print "hello, world"; exit}
acid
	print("hello, world");

that's 1/512th of your size limit, if you count all scripts
and all executables.

i have some variations on a theme:

linux, i386: main() { syscall(4, 1, "hello world\n", 12); } (~6KB
dynamically linked)
linux, x86: main() { syscall(1, 1, "hello world\n", 12); } (~6KB, 4KB
stripped; 2.4megs statically linked, 400KB statically linked and
stripped)

p9, shell: % syscall write 1 'hello world' 11
p9, c: void main(){_write(1, "hello world\n", 12);} (link with libc
manually, 3.3KB)

also, i discovered something new today:

"... decided to link everything dynamically. To enforce this (allmost)
all static libraries are removed (or not even build)..."

$ gcc t.c -static
/usr/bin/ld: cannot find -lc
collect2: ld returned 1 exit status

You can also use some alternative libcs for a reduced footprint, or
eliminate libc altogether with some simple inline assembly.  GNU is
really bloated.

I'm not sure where one draws the line though, theres also is a lot of
code and memory behind that syscall before anything is seen on the
screen, which could be considered part of the "linked" code.

One could always poke data into video memory and avoid all that, but
that does not get us the "Are you sure?" dialog box or status bars that
go from 0 to 100% over and over again.

and if you want something more cryptic (which was a whole lot fun to do):

What, no HQ9+?

Having "Hello, world!" as a semantic & syntactic element in the language
serves as the ridiculous part...
