Hi orgers,
In a mode derived from org-mode, I would like to hide some characters with a
special function to make the display cleaner. There are two cases:
- special characters that should be always invisible
- strings matched by a regex that should be invisible
I would be glad for any pointers or ideas on how to implement this, either
by piggy-packing on org-mode code or by using generic Emacs features.
All the best,
Christian

Meant to respond to this earlier. Reading this brought to mind the
setting =org-hide-leading-stars=. See this for more:
- http://orgmode.org/manual/Clean-view.html
Perhaps check out some of those variables, or at least the hiding of
leading stars, as it might at least give you some ideas of how this is
implemented in Org. I'm no elisper, so that's about the best I can
provide and I have no idea of Org's implementation will match your
goals, but it was worth a shot.
Best regards,
John

Hi,
maybe have a look how
ar-hide-bracketed-in-line-atpt
for example is implemented.
https://launchpad.net/s-x-emacs-werkstatt/
https://launchpad.net/s-x-emacs-werkstatt/trunk/1.3/+download/S-X-Emacs-Werkstatt-1.3.tar.gz
This provides a framework for tasks like this.
HTH,
Andreas

Hi Andreas, Hi John
Thank both of you for trying to get me on track.

I can't actually find this function, but I get the general point from the
files in Emacs Werkstatt.
What tripped me up originally that simply setting a region to 'invisible
worked in fundamental mode, but not in org-mode.
I found the solution after I finally understood what
(info "(elisp) Invisible Text")
was trying to tell me:
- first set the desired region(s) to an arbitrary symbol, like my-symbol:
(overlay-put (make-overlay beginning end) 'invisible 'my-symbol)
- next add this symbol to 'invisibility' spec :
(add-to-invisibility-spec 'my-symbol)
After straighting this out I am now a happy camper, enjoying my uncluttered
display.
All the best,
Christian

ar-hide-bracketed-in-line-atpt seems vanished indeed, something got broken. Thanks pointing at.
