Any idea why the following does not work: Your code does something you definitely shouldn't do: your advices make `hi-lock-set-file-patterns' and `hi-lock-find-patterns' switch to a different buffer (persistently!). When you need the context of another buffer, use `with-current-buffer' to switch to it temporarily. Maybe the following illustration may help: (defvar-local foo) Suppose we have two buffers buffer-a and buffer-b. buffer-a is current, and we want to set `foo's binding in buffer-a to `foo's value in buffer-b (I think this is what you try to do, more or less). This is how you can do it --8<---------------cut here---------------start------------->8--- (let (helper) ; temporary variable (not buffer local) (with-current-buffer buffer-b ;; set it to `foo's binding in buffer-b (setq helper foo)) ;;back in buffer-a (setq foo helper)) --8<---------------cut here---------------end--------------->8--- BTW, did you have a look at my example? I think it's quite close to what you want to achieve. Michael.
