[9fans] a little gotcha

[9fans] a little gotcha

[erik quanstrom]

don't do this under 9term in plan9port:

@{cd /somewhere; tar c} | tar x

took me a while to figure out what was going on, as just catting
the output looked fine.
1: "

the explaination is missing; i'm assuming that you're running into this
magic:

	fn cd { builtin cd $* && awd }

where awd outputs magic xterm escape codes.  if that's what you're talking
about the quick solution is

	@{ builtin cd /somewhere; tar c} | tar x

another way to work with this is to do this

	fn awd { tty -s < /dev/fd/1 && builtin awd $* }

asswards combackability.  ☺.  i tried to convince russ that
9term needed a /dev/label analog but he didn't agree.
his point was that you still need xterm escape sequences,
since most distributions use them in their shell prompts.

it might be reasonable to interpret them (along with cr-lf and bs), but that doesn't mean that p9p
stuff should *generate* them... it's a pity really that writing a 9p fileserver
for 9term to implement awd functionality isn't roughly the same amount of code
as interpreting the escape-sequence.

not the point.  most people i know using p9p don't actually use 9term.
i do, but i'm in the minority.

well then you're in a minority of one more. i can't see how anyone
would go back to a 70s tty emulation after having used rio for a while.
if i can't edit any text in the window or go into hold mode, i feel
like one hand's being tied behind my back...

anyway, an isatty check seems like a good plan.

I was surprised it was a minority.  I wouldn't want to live in a world
of xterms.

Re: [9fans] a little gotcha

[quanstro]

i've used 9term since it first appeared.  but it's true.  it doesn't
quite fit into unix.  readline, for example, does not work well.
i've added some support to recognize color escapes (and ignore them),
but there are some fancier editing tricks that readline uses that
9term doesn't recognize.  i didn't have the energy to fix those.
instead, i avoid bash. ;-)

oh, for isatty
	fn awd {tty -s </dev/fd/1 && awd $*}

that should be
	fn awd {tty -s </dev/fd/1 && builtin awd $*}

d'oh.

would readline be the thing that is always annoying me when i
try to send a line that's a little longer than it expects and i get a weird sequence
out, then most of the line repeated, then it settles down a bit until next time?

have some fun. In plan9ports rio, make a real little xterm window (with
bash in it), hit ^R, and watch the window disappear. It's fun if you're
like me and have a low fun threshhold :-)

That's far more fun than I can handle.  I'm going back to folding
socks WHOOPEEE!

I feel left out.  It doesn't work for me.  How will I have fun?

dang.

Well, in plan 9ports, I frequently don't use 9term (sorry), I use xterm.
You have to make it REALLY small, like 2 characters.

[quanstro]

he good news on the xterm front is they *finally* got utf-8 working.
about 10 years after 9term did.

About the only time I fire up xterm any more is to run pine.

When and if I ever run X and P9P it's always 9term.

Typically my unix boxes don't do X11 though... I've little to no use of it.

maybe awd or that fn cd needs to check isatty.
