export to latex broken

[Puneeth]

Hi,

Exporting from org to LaTeX is broken on the master.

Git bisect gives the bad commit as 034dbac3eecd
"Search for LaTeX setup case-insensitively"

-- Puneeth

ps : Thanks to ngz for a patient IRC tutorial on git bisect.

I can confirm it's broken.  I've not had time to really track down
where it is happening but I can say that all my latex files are
incorrect in the generation of the \documentclass{} line, specifically
an extra character is being inserted between "class" and "{", even
though I have specified my own org-export-latex-classes.  Very
strange.  I'll try to track this down on the way home on the train
tonight...

: Org-mode version 7.01trans (release_7.01h.180.g190e)

OK, I have reverted it.

Can you please describe what happened?

Thanks

Sorry for the incomplete report. I'd been using C-c C-e ?d and getting
a direct pdf output which was garbled.

Getting a LaTeX output and compiling gives me a clearer picture.

The documentclass is getting appended with a "random" character.
pdflatex gave me this error

-------------------------------------------
! Undefined control sequence.
l.2 \documentclassT
                   {article}

-------------------------------------------

Removing that "T" from the end of documentclass solves the problem.

(and I think the T is coming from the org file itself. I get a
different character in different documents.)

HTH,
Puneeth

line 1144 ff in org-latex.el:

                ....
		(and (let ((case-fold-search t))
		       (re-search-forward
			"^#\\+LaTeX_CLASS_OPTIONS:[ \t]*\\(.*?\\)[ \t]*$" nil t)
		       (match-string 1)))))

The and used to check for the match and if the match succeeded it would return
the match string. Now it returns the match string whether the search succeeds or not.
It probably should be:

                 ...
                 (let ((case-fold-search t))
                   (and (re-search-forward
			"^#\\+LaTeX_CLASS_OPTIONS:[ \t]*\\(.*?\\)[ \t]*$" nil t)
		       (match-string 1)))...

Carsten,

at least in my case, what happens is that the \documentclass line gets
munged somewhere along the way. I have the following for
org-export-latex-classes:

: (("article"
: "\\documentclass[11pt]{scrartcl}\n\\usepackage[utf8]{inputenc}\n..."))

(truncated).  When I export to latex, I get:

: % Created 2010-08-20 Fri 18:21
: \documentclassI{scrartcl}
: \usepackage[utf8]{inputenc}
: \usepackage[T1]{fontenc}

(truncated again)  Note the "I" after "class" which somehow has
replaced the "[11pt]" argument I had to this command.  In other latex
files, I have seen "r" instead of "I".

Hope this helps.

eric

PS - I sympathise with your response to another email on the list
     about crossing emails: I do much of my email processing on the train
     while off-line...  so I hope this doesn't cross the message from you
     that says that this problem has already been fixed ;-)

Hi,

I think this commit broke latex export.

$ git log -1 1f78ceb

Author: Nicolas Goaziou <n.goaziou@gmail.com>
Date:   Mon Feb 28 11:04:46 2011 +0100

    org-latex: fix export with various values for `org-list-ending-method'

    * lisp/org-latex.el (org-export-latex-lists): make sure markers used
      for export are taken into account by temporarily setting an
      appropriate value for `org-list-ending-method'.

Emacs (24) hangs with a message saying "Applying style hooks" in the
minibuffer and the cpu usage shoots up and I have to kill emacs. Can
someone else confirm this?

Yes its fixed now! Thanks a lot. :)

However after I sent my previous email I noticed a separate bug was
introduced in a commit somewhere between the previous commit I mentioned
and

commit d3432917ed8f95af0ce76127e632052fc7430439

    Merge branch 'master' of orgmode.org:org-mode

All babel source blocks are quoted inside a verbatim environment when
exported to latex. I haven't narrowed down the commit yet though.

IMO, you shouldn't bother trying to find the commit that introduced the
error (the one you cited earlier was actually wrong). It's better to
provide a test file, and some pertinent configuration variables.

I think I found the commit. This is the first time I used bisect, so
might be wrong. This is the output after git bisecting.

I have attached a test file and the exported tex file. I don't have any
customisations for latex export.

I hope this helps.
