p9p backspace/delete in osx

[Christopher Hobbs]

Being that macs don't have a proper delete key, how can I get delete
behavior to kill a program in rc short of slapping a real keyboard
on this machine?

i think it's function or apple +backspace. (doesn't work through a kvm.)

fn+delete works on both local and remote (X11 based) p9p acme and 9vx.

obviously not necessary when using a full-size keyboard, and there is a
real delete on those keyboards.

none of these works with an rc shell. all i see is:

printed with each method. repeatedly as i bash the keyboard with my stubby
fingers :)

You must be running p9p rc in a terminal window on the mac!
For that the interrupt key is whatever stty all shows you.
Probably ^C. If you are running rc under p9p acme or 9vx on
the mac fn+delete is the interrupt key. The same works with
a remote X windows p9p acme or 9vx or plan9/qemu running rc.

If he is running rc in a terminal window, he can use ^C. If
he is running rc in acme, he can use fn+delete to kill a
program. Assuming I have not misunderstood his problem. Which
I probably have, given how many messages have been exchanged!

Just use a multitouch gesture on the magic mouse. This makes it
completely keyboard agnostic.

just to make it clear: is this in 9term?

works with my old copy of p9p in 9term. when did p9p go broken?

i don't know. here's what i got with mac book and normal keyboards plugged
in today:

notably, ctrl+c worked.

delete to kill a program is a function of rio/9term/acme, not a function
of rc.

Not true. It's a feature of the terminal line discipline.

% stty
speed 38400 baud; line = 0;
intr = ^?; erase = ^H;

(The problem is that this only allows single chars as special keys,
so you can't bind '^[[3~'.)

(Actually, p9p 9term always sends the current intr-char on Delete, while
acme/win and matty's 9term always send ^?.)

the interrupt is delivered through the star wars-vintage
imperial garbage chute known as the tty subsystem, but
when i start 9term, stty intr is reset from ^C to ^?.
and if i change it back, then the fn+delete generates
escape codes, rather than an interrupt.

Not surprisingly i have 15+ threaded mail relted to osx.

Not on my p9p 9term:

% stty
speed 38400 baud; line = 0;
intr = ^?; erase = ^H;
-brkint -imaxbel
-onlcr onocr
% cat
^?
% stty intr '^C'
% cat
^C
% cat
<Press C-c, RET here>
^C

I pressed DEL twice, and after that C-c. The second DEL sends C-c, see

This is not what's happening: delete (which you type as fn-backspace, I
guess?) always sends the intr char, nevermind what it is set to
(in 9term, not acme!).
