Re: [O] custom emacs org-emphasis-alist breaks EXPORT, help ;-) ?
Working with font-lock keywords is quite messy. The good news is that you don't have to do it. If you want highlighting in the buffer or a file (and but not in the exported buffer), just go with hi-lock-mode. The relevant manual page is at C-h K C-x w b In your Org file do this, C-x C-f somefile.org M-x hi-lock-mode RET C-x w p server M- C-x w b C-x C-s C-x k C-x C-f somefile.org When you reopen the file hi-lock may ask some confusing questions. Answer those. You will see that now whenever you open the file, the word `server' is always highlighted. If you are adventurous, you can do C-h v font-lock-keywords within the org file and examine how it looks like for specific keywords you have added.

That's a bit unfortunate, since regexps aren't a great place to start! I'd recommend getting something that's close enough, and not going down the rabbit hole of perfect. Then start at the top of the introduction to elisp... Good luck, Eric

Hi Xebar, Xebar Saram zelt...@gmail.com writes: so after struggling for weeks to figure out why i always get an error when exporting i finally nailed the issue: org-emphasis-alist. i have alot of them (see below) and use them in orgmode quite often. is this a bug or if you want to use the exporter you should avoid using org-emphasis-alist? You use org-emphasis-alist to do simple highlighting, right? In that case, using you should better use `font-lock-add-keywords'. See http://www.emacswiki.org/emacs/AddKeywords for details.

Re: [O] custom emacs org-emphasis-alist breaks EXPORT, help ;-) ?
Thx Bastien! i look at it but it seemed highly complex (im an academic and dont know much (well nothing tbh :) ) about programming. is there a simple way of defining these like the GUI for org-emphasis-alist (i used customize-variables ) as you said i just want to highlight (BG/FG) specific areas/lines. any help would be greatly appreciated! best guys Itai On Fri, Oct 4, 2013 at 10:21 AM, Bastien b...@gnu.org wrote: Hi Xebar, Xebar Saram zelt...@gmail.com writes: so after struggling for weeks to figure out why i always get an error when exporting i finally nailed the issue: org-emphasis-alist. i have alot of them (see below) and use them in orgmode quite often. is this a bug or if you want to use the exporter you should avoid using org-emphasis-alist?

Not with font-lock-add-keywords, which I think is just for one-liner highlights (as the name suggests.)
