Subject: visual-line-mode produces erratic behaviour with text properties
Date: Fri, 01 Jul 2016 15:30:25 +1000 [thread overview]
Message-ID: <1467351025.3299202.653866593.5B4EE9EF@webmail.messagingengine.com> (raw)
Enabling visual-line-mode and adding line-prefix and wrap-prefix properties to a long paragraph of text produces erratic navigational behaviour. Can anyone else reproduce?
To reproduce:
1. $ emacs -Q
2. insert a long paragraph of text
M-: (url-insert-file-contents "https://gist.githubusercontent.com/rnkn/d5987c3495901e4950782f6648846e4e/raw/c22074e8f0940f6ec9c8b729f04567dc50664823/loren-ipsum.txt")
3. turn on visual line mode
M-: (visual-line-mode 1)
4. add text properties
M-: (add-text-properties (point-min) (point-max) '(line-prefix (space :align-to 10) wrap-prefix (space :align-to 10)))
5. C-n past window length and up and around.
Expected results:
Navigation should continue by visual line.
Actual results:
Navigational behaviour becomes erratic. Point will no long move with visual lines, instead jumping to different columns. This is more pronounced with a window 80 columns or less.
Configuration:
GNU Emacs 24.5.1 (x86_64-apple-darwin15.5.0, NS apple-appkit-1404.47) of 2016-06-26
OS X 10.11.4 (15E65)
MacBook Pro (Retina, 15-inch, Mid 2014)
2.2 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel Iris Pro 1536 MB
