I'm trying to bind ^L to a key sequence that will reset my xterm saved
lines. The escape sequence ^[c does the trick if I do
echo -n ^[c
at the command line. However, if I try
bindkey -s "^L" "echo -n ^[c"
it just prints a new prompt as if I'd typed return. (Note I've typed all
the control charaters using ^V first; I'm just typing them safely here.)
I managed to get somewhat the behavior I want by
zle -N clear-screen2
function clear-screen2 () { echo -n ^[c; zle clear-screen }
bindkey "^L" clear-screen2
Without the call to clear-screen, the prompt doesn't get printed, but with
it there's a slight flash.
I'm using xterm-70, if that makes any difference.
How should I be going about this?

^^
Right here's your key - -s puts the keys on the line as if you typed
them. Try typing 'echo -n ^[c' on the command line and see what
happens. Anyway, I think 'echo -n ^V^O' is what you really want; you
then don't need to associate it with clear-screen.

Which tells you what would happen with what you're trying with the
bindkey you're asking about - you'd get no prompt.
I handle this with
alias sanity='echo ^O; stty sane; stty -erase ^H'
I avoid the situation enough that a keybinding is not called for.
Considering the number of actual terminal lockups available from the
same source as your messed up charset, I think avoidance is probably a
good idea. (I saw one of those happen to a sysadmin at work, who was on
console on a machine which must not go down. Oops. Funny thing was, he
didn't realize it was a binary file until I showed it to him with less.
And some people wonder why I hate /bin/more with a passion.)

It does - it means you're talking about a dec-vt style terminal, which
is what I know best. You'll only have problems applying this to
something weird like wyse terminals (what the hey?!?) or ansi
(standards? Who ever follows standards?) (though dec-vt style is close
enough to ansi that it might carry over.)

D'Oh! It completely slipped my mind that I would have to include the ^V in
the bindkey out-string, too. That completely solves the problem; my saved
lines are reset, the screen is cleared, and I get a prompt printed (which
was what I wanted ... not to reset to a G0 charset and sane tty, though it
probably wouldn't hurt to throw that in anyway :).
I'm still not sure I see what's going on WRT the widget solution. It,
after all, should do the echo exactly like I want. I tried putting the
echo in a function and binding ^L to call that function, and that worked
fine, so I don't see why it doesn't work in a widget, unless I explicitly
have to tell zsh to print a prompt afterwards.
Anyway, thanks much. That should teach me not to try to learn new things
on so little sleep. ;-)

I would like a prompt, with parts that only shows when i'm editing the
command, like the mode line in emacs. Is this possible to have in zsh
without heavy modification of the source?
