Re: tex-mode.el

[Christopher Dimech]

I think that I have found a problem with my code, because when I applied
the two commands mentioned for tex-mode.el the fontifying was disabled on
the entire buffer.

(setq-local tex-fontify-script nil)
(font-lock-flush)

I am actually trying to write a minor-mode for suscript to work also
for texinfo, when one can call tex commands.  For texinfo, the
fontifying is enabled as soon as the mode is called.  However, for
my minor mode I would like that a function would set things up, and
another to disable it.

Have copied the following code parts from tex-mode.el and want to
write a function that enables the raising and lowering fontification.
And anothr that I can call to disable.  Have fount the setup in
tex-mode.el quite complicated.

--------

(defcustom tex-fontify-script t)
(defcustom tex-font-script-display '(-0.2 0.2))
(defcustom tex-suscript-height-ratio 0.8)
(defcustom tex-suscript-height-minimum 0.0)
(defun tex-suscript-height height)

(defface superscript )
(defface subscript )

(defun tex-font-lock-match-suscript limit)
(defun tex-font-lock-suscript pos)
(defun tex-font-lock-unfontify-region beg end)
