Why do you think it is an XEmacs problem?

What is your AucTeX version? I will suggest you to get the latest AucTeX
package, the feature which you are looking for is already present in it.
You can update your packages from the Tool -> Packages -> .... menu options or
you can do it directly from the XEmacs website.

HTH.

It's definitely soluble.

I found the tricky part to be getting to a state where you can push
blocks away from the top-left corner.

The following sequence of moves (where * indicates a push):

  down
  down
  right
  up
  right
  right
* right
  down
  right
  right
  right
* up
* up
  right
  up
  up
  left

highline.el and XEmacs

Hello, I use highline.el[1] to highlight alternative lines or
alternative N-lines.  Unfortunately under XEmacs there is a missing
feature: it can't highlight a line till the window border, only till the
last character of the line, as it is written inside the elisp file:

The .el file on my system
(/usr/share/xemacs21/xemacs-packages/lisp/edit-utils/highline.el.gz) says:

,----
| (defcustom highline-line nil
|   "*Specify which part of line should be highlighted.
|
| Valid values are:
|
|    t                  mark up to end of line.
|
|    nil                mark up to window border.  On XEmacs, it behaves as t.
|                       NOTE: Let me know, if you find a way to mark up to
|                             window border on XEmacs.
| (...)
`----

>From the code it seems to me that under GNU Emacs
  (move-overlay overlay foo (1+ (line-end-position))
makes this "till window border" stuff.

How can I make it work in XEmacs?

As far as I know, to make it work generally you have to patch the
redisplay engine.  It's probably only a couple of lines of C code, but
I can't really promise that.  It's also unobvious what the API to
control the feature should be.

If you have a monospace font, the LISP code could temporarily stuff
whitespace into the end of the highlighted lines.

Screwed up my fontifying

Hello,

I somehow managed to screw up my fontifying: Sometimes, if I open a file, 
xemacs starts to fontify all buffers, not just the new opened one... This 
can take quite a long time.

I didn't find the correct settings (fontify buffer when it is opened). 
Could you give me a quick hint ?

Thanks,

Fortunately I found a usable (but ugly) elisp solution, I put an extent
at the end of the line like this:

  (let ((ext (make-extent (line-beginning-position) (line-end-position)))
        ;; number of whitespaces
        (spacing-length (- (window-width (selected-window))
                           (save-excursion
                             (goto-char (line-end-position))
                             (current-column)))))
    (when (> spacing-length 0)
      (set-extent-property ext 'my-whitespace-extent t)
      (set-extent-property ext 'end-glyph
                           (make-glyph (make-string spacing-length ? )))
      (set-extent-property ext 'end-glyph-layout 'whitespace)))

How to highlight columns?


I'd like to highlight all text/code that's beyond column 80.
I cannot figure how to set font-lock to do that, not how to write an interactive functions to do that.

Any ideas?

Here's a simple example:

(defun highlight-tail ()
  (interactive)
  (let ((exp "^.\\{1,80\\}\\(.*\\)$")
	(face (find-face 'highlight)))
    (while (re-search-forward exp nil t)
      (let* ((start (match-beginning 1))
	     (end (match-end 1))
	     (extent (make-extent start end)))
	(set-extent-property extent 'face face)
	(goto-char end)))))

It highlights everything after the 80th character, which may not be
the 80th column due to characters spanning multiple columns (primarily
tabs, but also control characters using ^M or \015 display forms).

RE: How to highlight columns?

Good, except as you noted the tabs. Can it use the "tab-width" to compensate?
