Subject: Redisplay loop with an unicode overlay-arrow-string
Date: Thu, 21 Apr 2022 21:16:46 +0200 [thread overview]
Message-ID: <87o80u6ych.fsf@wavexx.thregr.org> (raw)
I'm disabling the left fringe to force using the overlay-arrow-string
(due to the fringe being unreadable on hidpi displays).
At some point I thought of being smart and attempt to:
(setq overlay-arrow-string "🡆") ; RIGHTWARDS HEAVY ARROW
since it's an uncommon/heavy character (while still being narrower than
"=>"). Or just in case it's not readable for you, a more commonly
available character:
(setq overlay-arrow-string "⮕") ; RIGHTWARDS BLACK ARROW
This results in an endless/unrecoverable redisplay loop on my current
config, hanging emacs.
To trigger on an emacs -q, evaluate this inside a buffer:
(fringe-mode 0) ; force-disable the fringe
(setq overlay-arrow-string "⮕")
(setq overlay-arrow-position
(set-marker (or overlay-arrow-position (make-marker))
(line-beginning-position)))
