[9fans] web plumbing on OS X drawterm

[9fans] web plumbing on OS X drawterm

[a]

OS X has this command 'open', which I'm told exists or is
available on other unixes. It's about as close as you get to
'plumb' when in foreign lands. You call it like 'open
http://9fans.net' or 'open /etc/passwd' and it does more
or less what you'd expect, finding (usually) the right app.

I mostly get to my Plan 9 cpu servers via drawterm from
my OS X laptop these days (9vx soon, once I get a
comfortable environment there). I have a script that
calls drawterm with the right arguments. I just added
this to the script:
	mkfifo /tmp/open.fifo
	while () {open `{cat open.fifo}}
I also have a srcipt on the Plan 9 side, 'web':
	#!/bin/rc

	fifoname=/mnt/term/tmp/open.fifo

	if (test -e $fifoname)
		echo $* > $fifoname
	if not
		lynx2txt $*
(for those unfamiliar, lynx2txt is like wurl2txt, but using
fgb's lynx port instead of hget to get things like tables).
So now 'web http://9fans.net' on my Plan 9 box opens up
a Safari window. Stick that in a plumbing rule and I can
now click on urls in my drawterm'd acme and have a
Safari window come up.

It's pretty nice, and took all of about two minutes. Maybe
useful for others.

There is a web command in plan9port, so this doesn't
need to be OS X specific:

	mkfifo /tmp/web.fifo
	while() { web `{cat /tmp/web.fifo} }

Ah, right. I'd started out using p9p's 'web', but
decided having access to 'open' might be useful
in other contexts, even if i'm not plumbing
anything to it right now.

Project for today is sort of the inverse: how to
make OS X use Acme-sac or B for text files.
Anyone looked at it?

i added /dev/showfile for windows a while back.  in that case, dt
hands anything it is given on /dev/showfile to explorer (closest thing
to plumber on windows).  plumb rule for urls hands them to a script
that looks like this:

	echo -n $* > /mnt/term/dev/showfile

Could you please tell me in more details where should I write it?
I am not familiar with plumb rules.

in $home/lib/plumbing add a line to plumb to winstart for the
following rule:

	type	is text
	data	matches '(https?|ftp|file|gopher|mailto|news|nntp|telnet|wais|prospero)://[a-zA-Z0-9_@\-]+([.:][a-zA-Z0-9_@\-]+)*/?[a-zA-Z0-9_?,%#~&/\-+=]+([:.][a-zA-Z0-9_?,%#~&/\-+=]+)*'
	plumb	to web
	plumb	start winstart $0

the script /rc/bin/winstart looks like this:

	#!/bin/rc
	echo -n $* > /mnt/term/dev/showfile

a better script would test existance of /dev/showfile first.
