word wrapping about eldoc-box HOT 10 CLOSED

Yeah I can fix that. Added to todo ; )

Have you tried eldoc-box-max-pixel-width?

Ah, I see. I would try

(add-hook 'eldoc-box-buffer-hook (lambda () (unless word-wrap (toggle-word-wrap))) nil t)

from eldoc-box.

It seems it prevents eldoc box from appearing

I made a mistake, it should be

(add-hook 'eldoc-box-buffer-hook (lambda () (unless word-wrap (toggle-word-wrap))) nil t)

It doesn't make sense to add the hook locally.

However, that mistake shouldn't prevent the childframe from appearing. FWIW, I tried the snippet and it seems to work. I couldn't think of a source of your problem on top of my head.

these hooks are the same, so I think you've meant:

(add-hook 'eldoc-box-buffer-hook (lambda () (unless word-wrap (toggle-word-wrap))))

This works. Thanks!

The solution posted by @andreyorst works great for word wrapping, thank you!

Just a minor annoyance that is probably not worth opening a new issue over: the arrows that indicate wrapping are getting squished at the edges of the window. Like this:

Also consider making word wrapping the default.

I pushed a change that enables visual-line-mode in child frame, give it a try :-)

I got rid of the hook function suggested earlier and indeed we are still wrapping at word boundaries, as per visual-line-mode. There are no more squished arrows either. Looks great to me!
