Hi,
is it still possible to add items to the emphasis alists?
I'm preparing a presentation with orgmode/beamer and try to get a markup
for alert using '@'.
According to some (old..) thread
(http://lists.gnu.org/archive/html/emacs-orgmode/2010-01/msg00592.html)
I added an entry to org-emhasis-alist and
org-export-latex-emphasis-alist, see below.
Unfortunately, this is not working, '@noise@' is exported to '@noise@'
literally.
I had a quick look at the source in org-latex.el and if I understand it
correctly, the fontification is done in org-export-latex-fontify
according to matches with org-emph-re, defined in org.el. But
org-emph-re doesn't match with '@'- consequently, the markup is ignored.
So do I have to redefine org-emph-re as well or is there any other trick?
I'm using the current org from git.
Thanks all!
;; this is how I add the entries to the lists
(setq org-emphasis-alist
(append org-emphasis-alist
'(("@" org-warning "<b>" "</b>"))))
(setq org-export-latex-emphasis-alist
(append org-export-latex-emphasis-alist
'(("@" "\\alert{%s}" nil))))
;; this is a minimal example
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_FRAME_LEVEL: 1

So if you arrange to call the org-set-emph-re function afterwards, you can change org-emphasis-alist at any time. Customize makes it easy, in that it does that automatically (see the :set property of org-emphasis-alist). If you do the setq before loading org, then what happens is that when the defcustom is encountered, the value of the :set property (a function) is called: the modified value of org-emphasis-alist is then used to calculate org-emph-re, instead of the original default. If you do it after, none of that happens and it's as if you never changed it. Nick PS BTW, the docstring for the variable says: "Use customize to modify this, or restart Emacs after changing it" but I'm not sure that's correct: if you change the variable in one session, the value is not going to be propagated to the next session, unless you use customize or put the setq in .emacs. In the latter case, it's not going to work unless you do it the way Seb describes: set it before loading Org. So restarting emacs is *not* enough.

At some point, emphasis markers will be hard-coded anyway. Though, it will be easy to change their meaning during the export process.

Thanks for the patch. As Nicolas said, emphasis markers will be hardcoded at some point, so we don't want to encourage users to tweak this in the meantime. I'll add a note about this in the release notes of Org 7.9. I'll not apply the patch, as it exposes the user to things we don't really want him to explore, such as `org-set-emph-re'... the current docstring is fine to me. > Hopefully, if I can contribute a `real' patch someday, the format will > be right ;) No doubt :) Ps: Think of using `C-x 4 a' to get a proper ChangeLog entry. -- Bastien ^ permalink raw reply [flat|nested] 7+ messages in thread
