* LaTeX export: underscores and the syntax package @ 2011-05-12 14:00 peter.frings 2011-05-14 2:51 ` Robert Love 0 siblings, 1 reply; 7+ messages in thread From: peter.frings @ 2011-05-12 14:00 UTC (permalink / raw) To: emacs-orgmode mailing list Good afternoon all, I spent the best part of the afternoon trying to figure out why an org-generated .tex file wouldn’t compile with my set-up. It turns out that the `syntax’ package messes a bit with the definition of an underscore, making it impossible to use the underscore in a \label. Unfortunately, the LaTeX exporter uses underscores in its section labels. Actually, it is possible to have the _ in \label: use the `nounderscore’ option with the syntax package. But you then do not get the tweaked underscore in plain text (unless you use \_ again). Since I’d like to keep the syntax package and the ease of using plain underscores, I’d like to avoid the _ in labels. Maybe I didn’t look hard enough, but I didn’t find an obvious way to change the way org generates the labels. Would it be an option to use the same label-generating code as AUCTeX mode? That would be very nice! Thanks, Peter. -- c++; // this makes c bigger but returns the old value ^ permalink raw reply [flat|nested] 7+ messages in thread

You can turn off the subscript interpretation of underscores globally in the file by using #+OPTIONS: ^:nil See section 12.2, "Export options", of the Org manual. AFAIK, there is no way to make underscores be underscores in some cases and trigger subscripts in other cases, in the same file. Nick ^ permalink raw reply [flat|nested] 7+ messages in thread

I have not observed any side-effects, but then again, my files aren’t that complicated either, only using rather simple markup and a few floating images, no complex math or so… I wouldn’t mind having it changed as a fix, if only to avoid clashes with the syntax package, which I use a lot. Furthermore, I personally dislike underscores: they’re ugly and harder to type than a hyphen, but since they’re generated automatically those arguments don’t stand a chance :-) Anyway, now I know where to look I can always change it after installing a new release of org :-) Cheers, Peter.

For the rest, I don't care. Thinking more about this, I think that people who want permanent links to sections in HTML pages will use CUSTOM_ID rather than relying on section numbers. OK, I am applying Nicolas' patch. - Carsten P.S. I think it counts as a bug in the syntax package, that it makes labels with underscore invalid. Maybe you could investigate this and submit a bug report? > > > Cheers, > Peter. > > > On 14 May 2011, at 05:50, Nick Dokos wrote: > >>> On May 12, 2011, at 9:00 AM, peter.frings@agfa.com wrote: >>> >>>> Good afternoon all, >>>> >>>> I spent the best part of the afternoon trying to figure out why an org-generated .tex file wouldn’t compile with my set-up.
