Can't use bindkey -c

Can't use bindkey -c

[Steve Talley]

I'm converting from tcsh to zsh, and have question:

Does zsh's "bindkey" allow the same functionality as tcsh's "bindkey
-c"?  This allows a keystroke to be bound to a builtin or external
command instead of an editor command.  This is useful when I'd like to
run a command and see it's output without having to destroy the
contents of the command-line buffer.

Example:

bindkey -c "^P" pwd

% vi /tmp/blah         <-- Type "^P" here
/usr/bin               <-- shell prints wd
% vi /tmp/blah         <-- I can continue typing here

If there's any way to do this in zsh, please let me know.

Thanks,

Steve

Currently the way to do this is:

bindkey -s "^P" "^qpwd\n"

in which the ^q saves the line on the buffer stack, which is restored
after "pwd\n" is executed as input (this assumes emacs bindings; it's
actually a little better to have push-input bound to something and use
that instead of the ^q).

Maybe other ways will be forthcoming.

Apart from the method that Peter has posted, if you have version 3.1.1
and have applied the patches that have been posted recently, the following
can be done:

bindkey "^P" run-pwd
zle -N run-pwd
function run-pwd {
  echo
  pwd
  zle redisplay
}

Presumably that patch will be in 3.1.2.  In a later version, there will
be a slightly more general solution, probably looking something like:

zle -N run-command
function run-command {
  zle trash-zle
  eval "$STACK"
  zle -s
}
bindkey -x "^P" run-command pwd
