Vi ZLE bindings: status in prompt?

Vi ZLE bindings: status in prompt?

Hello,

The Subject pretty much asks the question. I'd be delighted if there was
some way to add the Vi mode to the prompt. This is the only thing
preventing me from using bindkey -v. Any ideas?

Thanks in advance,
Tom

I have such a thing implemented. You can have a look at my .zshrc
to see how it works:

In short, it uses the show_mode function to display the mode
(normal or insert) and rewrites all vi widgets to also call
show_mode :) It overwrites some area in my (multi-line) prompt,
see also the screenshot on
http://gott-gehabt.de/800_wer_wir_sind/thomas/Homepage/pics/prompt.png
Doesn't work perfectly, though: for overly long lines, the
display may shift to where you don't want it. Of course, you
could also modify the show_mode function to display the mode in
the RPROMPT, then this problem would go away...

Ciao,
Thomas

That relies on being able to reposition the cursor to where the prompt
was last drawn, and write something new over it, without the real prompt
being reprinted.  Which is clever, if not entirely reliable.

In recent CVS snapshots there's a built-in widget called "reset-prompt"
that can be used to cause zle to redraw the true prompt.  That plus
the readonly KEYMAP parameter can probably be caused to do the right
thing, though you've still got to redefine all the vi widgets to call
reset-prompt on every mode change.

Thank you very much, this is exactly what I wanted!
