Hi,
Is there a reason why Beamer export does not place "\maketitle" in a frame?
The beamer user guide (I.3.4) specifies the following:
\begin{frame}
\titlepage
\end{frame}
But org-mode simply writes "\maketitle" outside of a frame.
This is important when you are using the same source to produce both a
beamer presentation and a beamerarticle print version. For the
presentation, you should use the ignorenonframetext class option, which
omits everything that is not between \begin{frame} and \end{frame}. Since
org doesn't write a frame for the title, then the title disappears.
Bug? I suspect so, as Beamer export is not following the format described
in the beamer manual.

Oh, I think I see the issue... there's only one org-latex-title-command. ;; 10. Title command. (org-element-normalize-string (cond ((string= "" title) nil) ((not (stringp org-latex-title-command)) nil) ((string-match "\\(?:[^%]\\|^\\)%s" org-latex-title-command) (format org-latex-title-command title)) (t org-latex-title-command))) An isolated \maketitle is ok for articles, but not for Beamer. So I suppose it's incorrect to press the same variable into service for both. hjh ^ permalink raw reply [flat|nested] 9+ messages in thread

Anyway, patch welcome. Sure, I can work on a patch. I'll need this in another month or so. One question, though: How would I determine the LaTeX document class programmatically? "Beamerarticle" uses the article class, with \usepackage{beamerarticle} in the preamble. This package redefines beamer commands so that they print somewhat reasonably well in article format. So, org needs to generate beamer-style commands, and that's done by the beamer backend. That is: Exporting as presentation (normal) - Backend = beamer - Document class = beamer Exporting as article - Backend = beamer - Document class = article In the former case, the title command should be wrapped in a frame. In the latter, it should not. Currently, I'm working around it by #+bind'ing org-latex-title-command, but I'd like that to be automatic. hjh ^ permalink raw reply [flat|nested] 9+ messages in thread

The patch is based on release_8.2.4 (as noted in my bug report from a few minutes ago, I can't perform any Beamer export against current master). If it doesn't apply against master, I'll be happy to tweak it, once the other bug is fixed. Let me know if there are any other problems, say, LISP style errors. I wrapped my change in a (let...) to isolate it from other bits of the code. Tests: - Export to beamer, presentation mode, without ignorenonframetext option: Title appears in its own frame, exactly as before. - Export to beamer, presentation mode, *with* ignorenonframetext option: Title appears in its own frame. Without the patch, the title frame was missing. - Export to beamer, using article class and the beamerarticle package: Title appears, without begin/end{frame} (same behavior as without the patch). I haven't signed FSF papers, though... I guess I should get on that. hjh [-- Attachment #1.2: Type: text/html, Size: 1455 bytes --] [-- Attachment #2: 0001-ox-beamer-Wrap-the-title-command-in-a-frame-for-beam.patch --] [-- Type: text/x-patch, Size: 1858 bytes --] From 1f70f3f41b266da204abd8dbcdddfefe648868eb Mon Sep 17 00:00:00 2001 From: James Harkins <jamshark70@dewdrop-world.net> Date: Sat, 11 Jan 2014 11:59:32 +0800 Subject: [PATCH] ox-beamer: Wrap the title command in a frame for "beamer" class This supports an option, described in the beamer user guide, for supporting material using the beamerarticle package. 1.

It may be totally unrelated to "beamer". You need to use a regexp to find out what class is used: (let ((beamer-class-p (and (stringp header) (org-string-match-p "^[ \t]*\\\\documentclass\\(?:\\[.*\\]\\)?{beamer}[ \t]*$" (nth 1 (assoc (plist-get info :latex-class) org-latex-classes))))))) > + (if (string= (plist-get info :latex-class) "beamer") > + (format "\\begin{frame}%s\\end{frame}" titlecmd) > + titlecmd)) You need to check if TITLECMD is nil before wrapping it within a frame. Ideally before defining BEAMER-CLASS-P. Regards, -- Nicolas Goaziou ^ permalink raw reply [flat|nested] 9+ messages in thread
