AFAIK, it is not very easy. Syntax highlighting is just a matter of applying the right text properties, but not line numbers. Native line numbering in Emacs is implemented on low level, and is not very exposed to Elisp. There is a limited set of options available for customization - all in `display-line-numbers' variable. See "16.24 Customization of Display" section in Emacs manual. I do not know anything built-in that can help in our situation, with line numbers to be applied selectively. We may try the approach taken by the old linum-mode, except that linum is infamous for its poor performance. So, it might be better to hack on https://git.savannah.gnu.org/cgit/emacs/elpa.git/tree/nlinum.el?h=externals/nlinum as suggested in lisp/obsolete/linum.el commentary. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
