Subject: [PATCH] Preserve math environments in title when exporting to LaTeX
Date: Mon, 25 Oct 2010 08:41:54 -0700	[thread overview]
Message-ID: <87ocai8ekd.fsf@berkeley.edu> (raw)

Hi all,

This patch fixes the issue I originally described here:
http://article.gmane.org/gmane.emacs.orgmode/32281

It preserves math-mode delimiters (e.g. "$" and "\(") in the document
title when exporting to LaTeX.  (That is, it prevents them from being
escaped, by running the title through org-export-preprocess-string,
which marks them with the org-protected property.)  It should work
regardless of whether the title is pulled from a headline, from the text
before the first headline, or from an explicit #+TITLE declaration.

(This is my first time contributing a patch to a Free Software project
-- so please, let me know what you think!)

Best,
Richard
