It seems like the variable fringe-indicator-alist can be modified to hide the line-wrap indicators on the edges / fringe of the window.

I am having trouble getting this to work properly in the GUI of emacs on MacOS.

I added the following to my init.el, but the changes are not having an effect. Is there something wrong with the way I'm trying to update the values?

Specifically, I want to change continuation to nil nil.

(setq fringe-indicator-alist '((truncation nil nil)
    (continuation nil nil)
    (overlay-arrow . right-triangle)
    (up . up-arrow)
    (down . down-arrow)
    (top top-left-angle top-right-angle)
    (bottom bottom-left-angle bottom-right-angle top-right-angle top-left-angle)
    (top-bottom left-bracket right-bracket top-right-angle top-left-angle)
    (empty-line . empty-line)
    (unknown . question-mark)))

  • Are you using Emacs in the Terminal, or the GUI version of Emacs? Emacs in the Terminal does not use fringes.

  • @lawlist I'm using the GUI version (updated in post).

  • TEST: *No .emacs. Open a GUI version of Emacs, in this case 27.2-3 downloaded from emacsformacosx.com . The default buffer that is visible is *GNU Emacs*. The line "GNU Emacs 27.2 (build 1, x86_64-apple-darwin15.6.0, NS appkit-1404.47 Version 10.11.6 (Build 15G22010))" is wrapped. I evaluate (setq truncate-lines t) and the aforementioned line of text is now continued beyond the length of the screen, and there is a right-arrow visible in the fringe. Then, I evaluate the code posted by the O.P. in the question above, and the right-arrow (continuation) disappears.

Reset to default

The fringe-indicator-alist is a buffer-local variable, which means that the code the O.P. wishes to use should either be evaluated in every buffer desired, or set the default value by using setq-default.

`fringe-indicator-alist' is a variable defined in ‘C source code’.
Its value is shown below.

  Automatically becomes buffer-local when set.
  Probably introduced at or before Emacs version 22.1.

  • Thanks — updating setq to setq-default in init.el did the trick.
