Hi list,
I use noweb-mode a lot. This mode allows to have several languages in
one file (e.g. latex and R) and switch major modes automatically
depending on where the cursor is -- very useful! However, every time
modes are switched the font size (which I set with text-scale-adjust)
changes back to the default. Is there a way to make the font size
persistent? Note that I'd like to use different font sizes in
different buffers, so setting the default font size a specific value
is not a solution.
Thanks!
Titus

AFAIK, text scaling is on a per-buffer basis. You could perhaps implement a
workaround for your problem using `(after-)change-major-mode-hook'.
Another thing you could do, but which goes against your last sentence, is to
zoom the frame (yes, change its default font size) instead of scaling the text
of various buffers. See http://www.emacswiki.org/emacs/SetFonts#toc6 and

Hi Drew, thanks for your suggestion. Below is my solution. I don't
know if this is the idiomatic way of doing these things but it seems
to work.
;; Restore text-scale after change of major mode.
(autoload 'text-scale-mode "face-remap")
(add-hook 'change-major-mode-hook (lambda ()
(put 'text-scale-mode-amount 'permanent-local t)))
(add-hook 'after-change-major-mode-hook 'text-scale-mode)
Cheers,
Titus
