Here is example from Emacs library: (deffac= e ansi-color-black '((t :foreground "black" :background "black")) "Face use= d to render black color code." :group 'ansi-colors :version "28.1") Now tha= t means it should not be hard to replicate it and create your own face with= foreground and background and then to use the function` highlight-regexp' = as above shown or as: > >=20 > > (highlight-regexp "^;; \\[.$" 'my-face) > >=20 > > -- > > Jean >=20 >=20 > Made my own face with your help. Would you know the problem with the following regexp "^;; \\[.+\\].*$" It fails to match ;; [something] other things
