Bug: Problems with sub/super-script when using: org-cdlatex + org-pretty-entities + org-catch-invisible-edits

[Anders Johansson]

Hi,
I used the configuration:

org-catch-invisible-edits 'show
org-pretty-entities t

together with org-cdlatex. This breaks the insertion of subscripts and 
superscripts through org-cdlatex because _{} is fontified and the {} are 
hidden so typing for example: "a _ bc" results in "a_{b}c" (or sometimes 
"a_bc", but should be "a_{bc}") and gives the message "Unfolding 
invisible region around point before editing".

Setting org-catch-invisible-edits to nil let's cdlatex do it's work so I 
guess an easy solution would be to "let" that in 
org-cdlatex-underscore-caret.


Cheers,
Anders Johansson

Hi,
I realized that my solution won't work since 
"org-check-before-invisible-edit" does it's work after 
"org-cdlatex-underscore-caret" has called "cdlatex-sub-superscript" and 
inserted "_{}".

Maybe then org-catch-invisible-edits should be nil all the time in 
org-cdlatex-mode? But this would be unexpected. Maybe this can be 
treated as a special case in "org-check-before-invisible-edit" in some way?

Digging into it some more it's actually the "pretty entities" folding 
which is the problem, regardless of org-check-before-invisible-edit. The 
cursor jumps out of the {}-brackets after the first character, when the 
hiding/folding is done. I have no idea what should be done about this.

In case anyone has the same problem, my current workaraound for this is 
disabling "pretty entities" for sub/superscript when using cdlatex:

(add-hook 'cdlatex-mode-hook
  (lambda () (when (eq major-mode 'org-mode)
   (make-local-variable 'org-pretty-entities-include-sub-superscripts)
    (setq org-pretty-entities-include-sub-superscripts nil))))

Did you fish around enough to find a workaround? I have the same problem...

Cheers!

Hi,

you want to set

(setq org-pretty-entities-include-sub-superscripts nil)

before using `org-cdlatex-mode'.

HTH,

Bastien,

Aaaah, thanks, it works great!
I looked for hours for a setting of the sort...

I do still think that this is a bug however: when I don't use the setting
you provided and don't use pretty-entities, after I place the
sub/superscript sign, the point gets places inside the braces. If I do use
pretty-entities however, the cursor gets placed *after* the brace pair, and
this is what causes problems - I would expect the point to get inside the
brace pair, as at least to my understanding, pretty-entities should change
the way things look, but not how they behave... What do you think?

Other than that, I have a feature suggestion that I'm throwing out there:
It would be really cool
I think it would be really cool if there was an option to expand
sub/superscript braces when the point is near them.

Other than that, I also noticed that after I export to PDF, my kill-ring
gets filled with a bunch of tex and/or output pieces. Is this
expected/known behaviour or should I investigate it further on my end?

Thanks,
Kosta
