URGENT Need help fixing beamer exporting, can someone jump on IRC?

[James Harkins]

Hi, sorry to press, but is anyone on the org-mode IRC channel?

The new beamer exporter has suddenly gotten borked on my system and I
can't restore it. I have class tomorrow morning. This is an emergency.

This occurred after updating master to test a fix that Bastien pushed.
Recalling advice from others to use "maint" for production, I did "git
checkout maint" and "make clean" and now Emacs fails to initialize.

Symbol's value as variable is void: org-babel-tangle-lang-exts

I figure IRC is faster than e-mail (especially since I read the digest
only). But, nobody is answering.

Again, it's urgent. It's 11:15 PM here in China and I have to be up at
6:30 AM. Didn't quite want to be staying up late fixing my org
configuration...

Thanks,
hjh

OK, in desperation, I checked out my sandbox branch (based on master),
cleaned all the elc files, and quit and relaunched Emacs. Now it's
fine.

I had been using C-c C-x ! to reload org after doing a "make" but this
turned out to mess things up pretty badly. I could get reasonable
behavior only by quitting emacs and restarting it. I don't know if
that should be considered a bug or not. Perhaps I don't understand
what C-c C-x ! is supposed to do? Tonight at least, it was totally
unreliable.

So, crisis averted, but it was quite scary to get essentially complete
garbage from the beamer exporter...

You can't switch between maint and master without restarting Emacs.  Even when
it appears to work it really doesn't.

org-reload is there for convenience, quite often a proper emacs restart
is indeed required to get a consistent Org instance.

That said, I have noticed something odd about the new exporter and
org-reload.  I think with the new exporter after doing org-reload, org
related config is not reloaded properly.  This borks the Org instance.
This is more visible when using the Beamer backend since it requires
customisation of org-latex-classes by the user.  One of these days, I'll
try to come up with a proper recipe to reproduce this.

Config is not reloaded at all (and never has been), any configuration
variables that are already existing are not touched when the file gets
reloaded.

Please do, this should not happen.

[Bug] beamer backend and org-reload

Here is the recipe:

1. emacs -nw -Q -l ~/minimal-org.el

   ;;; minimal-org.el: Minimal setup to load latest `org-mode'
   
   ;;; Code:
   (setq debug-on-error t
         debug-on-signal nil
         debug-on-quit nil)
   
   (add-to-list 'load-path (expand-file-name "~/build/org-mode/lisp"))
   
   (require 'ox-beamer)
   (add-to-list 'org-latex-classes
                '("beamer"
                  "\\documentclass\[presentation\]\{beamer\}"
                  ("\\section\{%s\}" . "\\section*\{%s\}")
                  ("\\subsection\{%s\}" . "\\subsection*\{%s\}")
                  ("\\subsubsection\{%s\}" . "\\subsubsection*\{%s\}")))

2. C-x C-f some-file.org RET
3. Now try to export: C-c C-e.  You can see menu options for beamer export.
4. Now reload Org: C-c C-x !.  Try step 3 again.  You will notice the
   entries for beamer is missing.

This might actually be a problem with ox-beamer and not org-reload
because I noticed my other Org customisations do stay intact (which is
of course in line with your comment about settings not being touched).

Instead of step (3), you could also try M-x org-beamer-export-as-latex.
After step (4), repeating this alternate step (3) should give you the
following backtrace.

Debugger entered--Lisp error: (error "Unknown \"beamer\" back-end: Aborting export")
  signal(error ("Unknown \"beamer\" back-end: Aborting export"))
  error("Unknown \"%s\" back-end: Aborting export" beamer)
  org-export-barf-if-invalid-backend(beamer)
  org-export-as(beamer nil nil nil nil)
  org-export-to-buffer(beamer "*Org BEAMER Export*" nil nil nil nil)
  org-beamer-export-as-latex()
  call-interactively(org-beamer-export-as-latex record nil)
  command-execute(org-beamer-export-as-latex record)
  execute-extended-command(nil "org-beamer-export-as-latex")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

Hopefully my recipe is complete to fix this issue.

Pilot error, I'd say: org-latex-classes is a defcustom, I don't think it
is a good idea to muck with the data directly (it doesn't have
getter/setter methods IIRC, but still).  So what happens when you add
the beamer classes properly, via customize — and then do an org-reload?

I see the same problem when I put the following in my minimal-org.el

(custom-set-variables
 '(org-latex-classes (quote (("beamer" "\\documentclass[presentation]{beamer}" ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("chapter" "\\documentclass[11pt]{report}" ("\\chapter{%s}" . "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("article" "\\documentclass[11pt]{article}" ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}") ("\\paragraph{%s}" . "\\paragraph*{%s}") ("\\subparagraph{%s}" . "\\subparagraph*{%s}")) ("report" "\\documentclass[11pt]{report}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" . "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("book" "\\documentclass[11pt]{book}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" . "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")))))
)

I did encounter another curious problem though.  When in the customise
buffer I try to add a new class, I get a customize interface similar to
what is shown below.

  [INS] [DEL] List:
              LaTeX class: beamer
              LaTeX header: \documentclass[presentation]{article}
              Choice: [Value Menu] Heading:
                numbered: \section{%s}
              unnumbered: \section*{%s}
  [INS] [DEL] List:
              LaTeX class: article
              LaTeX header: \documentclass[11pt]{article}
              Levels:
              [INS] [DEL] Choice: [Value Menu] Heading:
                            numbered: \section{%s}
                          unnumbered: \section*{%s}
              [INS] [DEL] Choice: [Value Menu] Heading:
                            numbered: \subsection{%s}
                          unnumbered: \subsection*{%s}
  [...]

As you can see, there is no way to add deeper sectioning entries for the
new entry (beamer).  I worked around it for the moment to proceed with
my test, but I find this very curious indeed.
