dotemacs/tests/test-system-lib-font-lock-global-modes.el, branch main My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-06-16T12:58:26+00:00 fix(mail): theme mu4e buffers via a shared font-lock exclusion 2026-06-16T12:58:26+00:00 Craig Jennings c@cjennings.net 2026-06-16T12:58:26+00:00 urn:sha1:56d105f0ec3b7e5e4088d0683ae9cc5797442854 mu4e paints its header lines, main menu, and view headers with manual `face' text properties. Global font-lock stripped them, so the buffers rendered unthemed, the same failure the dashboard hit. I extracted the dashboard's one-off exclusion into a shared, additive cj/exclude-from-global-font-lock helper in system-lib and repointed the dashboard to it. Then I excluded mu4e-headers-mode, mu4e-main-mode, and mu4e-view-mode. The view body renders through gnus's own washing rather than font-lock, so excluding it is safe.
