Subject: bug#44521: 27.1; ivy.el breaks harfbuzz Arabic shaping
Date: Sun, 08 Nov 2020 19:15:37 +0300 [thread overview]
Message-ID: <87tutz4yfq.fsf@brutus.matara> (raw)
When using ivy.el, some Arabic letters become disconnected. This bug
doesn't affect Emacs 26.3 or any build "--without-harfbuzz".
1. Eval:
(progn
(load-library "~/.emacs.d/elpa/ivy-0.13.0/ivy-overlay.el")
(load-library "~/.emacs.d/elpa/ivy-0.13.0/colir.el")
(load-library "~/.emacs.d/elpa/ivy-0.13.0/ivy.el")
(ivy-mode t)
(run-with-timer .5 nil 'set-input-method "arabic")
(run-with-timer .5 nil 'insert "السلام عليكم")
(execute-extended-command nil))
2. While still in the minibuffer, type any Arabic letter. Note the
AIN(ع) in "عليكم" changes shape from initial to final.
This bug breaks shaping in most buffers, especially after using
swiper.el (ivy-based isearch).
