Subject: 30.0.91; which-key error in speedbar (wrong-type-argument wholenump
 -13)
Date: Mon, 30 Sep 2024 19:08:13 +0100

An error is signalled when which-key is activated, point is within the
speedbar frame, and a portion of a key-sequence has been typed
(e.g. C-x).

To generate an example backtrace:

  emacs -Q \
      --eval "(which-key-mode)" \
      --eval "(speedbar-get-focus)" \
      --eval "(toggle-debug-on-error)" \
      --eval "(setq unread-command-events (listify-key-sequence \"\C-x\"))"

Here's the error I get:

Debugger entered--Lisp error: (wrong-type-argument wholenump -14)
  make-string(-14 32)

The problem occurs is in `which-key--pad-column': the speedbar frame is
only 14 characters wide, and so can't fit longer strings than that.

I actually see two bugs here:

1. Create a regular Emacs frame of width 14, enable `which-key-mode' and
   press some key, e.g. C-h.  You now get a similar backtrace.  Probably
   `which-key' should simply be smarter in this case, for example by
   truncating instead of padding.

2. With a dframe, as in speedbar, I guess `which-key' should try to
   display it's help window in the original frame?

I'm copying in Justin Burkett.

[Message part 1 (text/plain, inline)]

Thanks. Can you try the attached patch for the first problem?

I'm not sure what the best approach is with speedbar. I'm inclined to
disable which-key for that case, but maybe showing which-key in the
original frame is better?

Could you use string-pixel-width there instead of
which-key--col-widths?  If not, why not?

I vote for the latter.

Thanks.
