I can reproduce what the original bug report is seeing -- but that's because the regexp seems to be wrong? There's nothing in the test file that matches "# endif". However the following call does properly match the region I think was intended, and works fine, as far as I can see (in Emacs 26.1 and 28): (highlight-regexp "def HALF_LJ[^^]+?# +endif") Or do I misunderstand what the original problem was? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
