That is not a bug. When you do (global-visual-line-mode) [which should better be (global-visual-line-mode 1), BTW], the function adds code to several hooks to check for new buffers (find-file-hook, etc.). In your first case, the global mode is active (so the hooks are active); when you run find-file, it creates the buffer, runs html-mode-hook (disabling visual-line-mode), and finally a hook is run which activates the mode. In the second case, you activate the global mode, run find-file (and the hooks check that visual mode is active, so do nothing), and finally run visual-off-fill-on, deactivating the visual-line mode. If you want to deactivate the mode automatically after find-file, there are several ways, like an `after' advice for find-file, or adding code to the relevant hooks, etc. Juanma ^ permalink raw reply [flat|nested] 8+ messages in thread

We agree, I think: it's not a feature, nor a bug. It's an epiphenomenon of the current implementation of global minor modes. Juanma ^ permalink raw reply [flat|nested] 8+ messages in thread

You mean for major modes which follow a particular convention (convention which could be automatically enforced by define-derived-mode)?
