[9fans] Abaco's Web Page Name in winwatch

I realize that abaco manages multiple web pages itself,
but, for reasons I won't go into, I generally launch a new
small abaco window for each web page. To help this style
of usage along, I've been trying to incorporate writing
to /dev/label into the abaco code. I took this bit

int fd;
fd = open("/dev/label", OWRITE);
if(fd >= 0) {
write(fd, title, strlen((char *)title));
close(fd);
}

from plan9.c in links-varfont since links exhibits the
behavior I'm looking for. I've tried using this substituting
various combinations of w->tag, w->page.title, &w->tag,
&w->page.title etc. for "title" and putting the lot into
winsettag1 in abaco/wind.c with no luck (In most cases,
either the build fails with prototype mismatch, or the
build is successful, but I only get an apparently unrelated
character or two in winwatch).

The usual I'm-no-programmer-apologies etc. etc.

Thanks for any help moving this small customization along.

I use winwatch with my plan 9 box (when it's running) to manage something
like virtual desktops with sub-rio sessions. Winwatch actually helps me
manage the sub-rio's.
I just have a bunch of rc scripts edit /dev/label via echo etc. I don't
bother with C coding unless I absolutely have to on Plan 9.

But let your communication be, Yea, yea; Nay, nay: for whatsoever is more
than these cometh of evil.

I had some success with echoing to /dev/label from the
plumber, but timing seems to be an issue. If I don't bind
/dev/null /dev/label, I end up with winwatch showing "abaco".
If I do, I get the web page name in winwatch for new windows
but not when I open a new link within a window.

Perhaps I just need to think harder about how to do this
with rc. I'm certainly not opposed to that approach. Any
suggestions along these lines will be greatly appreciated
as well.

label is a Runestr, not a char*. what you want is

void
updlabel(void)
{
int fd, n;

fd = open("/dev/label", OWRITE);
if(fd == -1)
return;
fprint(fd, "%#.*S", title.nr, title.r);
close(fd);
}

Thanks.

That's much nicer than what I was doing with the plumber. It not only
updates winwatch with a new name when I stay within a single window,
but the page names, like "Plan 9 from Bell Labs" are nicer than the
plumber's argument "http://cm.bell-labs.com/plan9/".
