From 5923088d754d448616678f05ddd27d70760d4534 Mon Sep 17 00:00:00 2001 From: Andres Gomez Date: Wed, 9 Nov 2016 18:32:41 +0200 Subject: [PATCH] dir-locals.el: Adds White Space support Trailing white spaces will be now always highlighted, not just in prog-mode. Also, the White Space package, which is available since GNU Emacs 22, is loaded and activated locally in prog-mode. Additionally, using White Space variables, we set highlighting through faces on wrong indentation and the maximum length of a coding line. Notice that: - The highlighting for the characters beyond the set length of a coding line is not activated by default, only for wrong indentations. - If the White Space package is not available, errors on loading or activation are ignored. - If the White Space mode is not activated the set variables would not have any effect. v2: Removed too long lines trail highlighting, as suggested by Ilia Mirkin.
