fontification strikethrough unpleasantness with error forms in tables

fontification strikethrough unpleasantness with error forms in tables

[William Henney]

Hi list

Consider the following table:

         | line | variance             | mean               |
         |------+----------------------+--------------------|
         | oiii | 115.1801 +/- 37.7650 | 18.6588 +/- 2.6645 |
         | ha   | 197.3689 +/- 35.9261 | 19.5581 +/- 2.8181 |
         | nii  | 107.8689 +/- 32.3098 | 20.4745 +/- 2.9728 |
         |------+----------------------+--------------------|

Org seems to assume that the + in the bottom right cell and the first
+ in bottom hline are matching strikethrough indicators and fontifies
it accordingly! Is it possible to fix this?

Cheers

Will

P.S. I tried "#+OPTIONS: *:nil" but this has no effect

In the meantime, I have discovered a work-around is to add a blank row
to the table before the hline:

         | line | variance             | mean               |
         |------+----------------------+--------------------|
         | oiii | 115.1801 +/- 37.7650 | 18.6588 +/- 2.6645 |
         | ha   | 197.3689 +/- 35.9261 | 19.5581 +/- 2.8181 |
         | nii  | 107.8689 +/- 32.3098 | 20.4745 +/- 2.9728 |
         |      |                      |                    |
         |------+----------------------+--------------------|

Cheers

I can't reproduce this either.
However did you consider using the symbol  " ± " ? ;-))

Strange. I'm attaching a (heavily compressed) screen shot that
illustrates the problem. (Please let me know if this is a breach of
list etiquette...)

This is what I get when I do "C-u C-x =" on one of the characters in
the problem area:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  character: 0 (48, #o60, #x30, U+0030)
    charset: ascii (ASCII (ISO646 IRV))
 code point: #x30
     syntax: w 	which means: word
   category: a:ASCII l:Latin
buffer code: #x30
  file code: #x30 (encoded by coding system undecided-unix)
    display: by this font (glyph code)
     -apple-monaco-medium-r-normal--14-140-72-72-m-140-iso10646-1 (#x30)

There are text properties here:
  face                 (:strike-through t org-table)
  font-lock-multiline  t
  fontified            t
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Does it have something to do with the font-lock-multiline variable?

> However did you consider using the symbol  " ± " ? ;-))

Funnily enough, I had thought of that. This is OK so long as as you
are not using formulae, but calc will not interpret a ± b correctly as
an error form.

Slightly off-topic, but another problem I had with using unicode math
characters in tables is that the special characters (e.g., √〈α²〉) are
variable width, even though I use what is supposedly a fixed-width
font. I imagine that this is very system specific (I'm using aquamacs
on os x), but I wonder if anyone on the list has a solution to this
(on any system...).

Cheers

Will

So If I'm correct: 
Operating system  Mac OsX ... version?
emacs version     aquamacs ?     
org-mode version           ?

here I have:  
winxp, 
GNU Emacs 22.0.990.1 (i386-mingw-nt5.1.2600) of 2007-05-23 on
LENNART-69DE564 (patched)
Org-mode version 4.67c

Cheers,
Giovanni

Yes, you are quite right that I should have reported my system
details. I have now run some more extensive tests and I can reproduce
the strikethrough problem using a recent build of vanilla emacs,
disabling all my customizations and without loading any extra packages
(apart from org-mode):

GNU Emacs 22.1.50 (powerpc-apple-darwin7.9.0, Carbon Version 1.6.0) of
2007-06-05 on applecore.inf.ed.ac.uk

This is with org version 4.77 and the only contents of my .emacs are as follows:

(add-to-list 'load-path (expand-file-name "~/emacs/lisp/org"))
(add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
(define-key global-map "\C-cl" 'org-store-link)
(define-key global-map "\C-ca" 'org-agenda)
(setq org-directory "~/Org/")

Note that the problem does not exist with the version of org that
ships with emacs (4.67c)

Can anyone else reproduce the bug?

Cheers

Will

I have the latest CVS emacs and still cannot reproduce this.

Until I can, I would not know how to fix it.

Yeah, I appreciate that. I will put in some more effort to pin down
the exact conditions needed to trigger the bug. Won't be for a few
days though - too much real work to do ....

Cheers
