Different set of packages for LaTeX export

Different set of packages for LaTeX export

[Manfred Lotz]

Hi all,
I have configured LaTeX export for using xelatex. For this I have
defined a list of packages in org-latex-default-packages-alist. One of
those packages is hyperref with certain options.

When creating a normal document, e.g. using class article that works
fine.

When creating slides, i.e using beamer I get an option clash
during compiling the tex file because beamer did already load hyperref.

How can I solve it? 

Could I have a different package list if the class is beamer?

No you can only discriminate based on the compiler version (and actually
only in ox-latex, not ox-beamer).

You can use a filter to remove hyperref.  AFAIK, there's only issues if
you use funny options for hyperref, e.g. I use

    ("unicode, psdextra,hidelinks" "hyperref" nil).

Last I checked there was an open bug report for this, so it might have
been fixed in upstream beamer.

I use this filter to remove hyperref in beamer exports:

       (defun rasmus/org-beamer-filter-remove-hyperref (text backend info)
         "Remove hyperref from beamer tex files.

     My default values are incompatible with beamer."
         ;; TODO: make better solution; check if still necessary
         (when (org-export-derived-backend-p backend 'beamer)
           (replace-regexp-in-string
            "\\\\usepackage\\[\\(.*?\\)\\]{hyperref}\n"
            ""
            text)))

       (add-to-list 'org-export-filter-final-output-functions
                    'rasmus/org-beamer-filter-remove-hyperref)


Hope it helps,
Rasmus

Hm, I think it would be great if a package list could be mapped to a
certain LaTeX class.

I have this 
      ("colorlinks=true, urlcolor=FireBrick, plainpages=false,
pdfpagelabels, bookmarksnumbered" "hyperref" nil)

which IMHO doesn't look to exotic.

Yep, this works fine.


Thanks a lot for your help.

To solve this, I set up my own LaTeX class. I find it at least as good as
to rely
on Org configuration. Actually, I removed the list of packages that Org is
exporting.
My LaTeX class can produce slides, course notes, exams and so on. Based on
options, I can chose which kind of document and a few things like the style
(font, etc.).

Hi Fabrice,
Hope you are well. Last time I saw you was in Pont-à-Mousson in
2005.

You are right, of course. Using my own class I have the full control to
do what I like.


Thanks for the idea.

The way I do it: I have different classes for different types of export
(beamer, or "normal") and I'm using different projects to choose from at
export time. The following code is at the beginning of the org file and
has to be run (C-c C-c) when you open the org file. The publishing
functions are just here to rename the pdf file.
