How can I as an emacs prelude (-nw) user turn off the 80 column warning highlight seen here:
That effect comes from
whitespace-mode, enabled by default in Prelude.
If you want to keep the effect but set it at a different column, you can set
whitespace-line-column to a value you like. If you want to disable the effect, remove
Make these changes in your
init.el (which ever one you use). Something like the following would keep Prelude's default
whitespace-mode settings but disable "greater than 80 column highlighting":
;; Change Prelude's default whitespace-mode settings (setq whitespace-style '(face tabs empty trailing))
And the following should disable all
;; Turn off whitespace-mode styling (setq whitespace-style nil)
If you don't care about
whitespace-mode at all, you could unload it:
;; Disable whitespace-mode entirely (unload-feature whitespace-mode)
Although, if another library relies on
whitespace-mode, it may not be able to be unloaded.
