view-mode dismissed when changing major mode

view-mode dismissed when changing major mode

[Holger Sparr]

Hi,

When opening a file with view-file and then switching to a different
major mode to get some fontification the view-mode is dismmissed.

Is this intended behavior?

I am currently using:

GNU Emacs 22.0.93.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

Yes.

    (defun view-mode-enable ()
      "Turn on View mode."
      ;; Always leave view mode before changing major mode.
      ;; This is to guarantee that the buffer-read-only variable is restored.
      (add-hook 'change-major-mode-hook 'view-mode-disable nil t)
      [...]

Then I'd suggest a function 'View-fontify-buffer-according-to' and make
it available in the view-mode-map.  

This function should ask for a major mode for fontification, apply the
fontification and enable the view-mode afterwards.

This would make it handy to view files which do not match a regular
expression in auto-mode-alist.
