Using KOMA and Memoir?

Using KOMA and Memoir?

[Martin Schöön]

[-- Attachment #1: Type: text/plain, Size: 623 bytes --]

I have tried to get KOMA and Memoir work in Org-mode. In short: I only get
error messages telling me they are unknown LaTeX classes.

I have looked in the archives with little success. All I find is a KOMA
letter thing.
I have looked all over the web (no, not really) but with little success.

I am in the middle of a small project for which I think KOMA's article
class is a better choice than the ordinary article class. How do I make it
work? Is it even possible?

This hobby, not work, so don't drop everything you are doing to help me.

It would help to know what you have actually tried.

I have the following in my org customisation files:

#+begin_src emacs-lisp
  (add-to-list 'org-latex-classes
               '("komaarticle" "\\documentclass{scrartcl}"
                 ("\\section{%s}" . "\\section*{%s}")
                 ("\\subsection{%s}" . "\\subsection*{%s}")
                 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
                 ("\\paragraph{%s}" . "\\paragraph*{%s}")
                 ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))
#+end_src

which defines the komaarticle class to use scrartcl from koma.  In the
org file, I then have

#+begin_src org
  ,#+latex_class: komaarticle
#+end_src

HTH,
eric

Thanks Eric, that was quick. I will try it but not tonight, too tired. And
I have to figure out what an org customisation file is. So far I have only
modified my .emacs.

Sorry for my brevity. What I tried was the first thing I could think of:
#+LATEX_CLASS: memoir
end
#+LATEX_CLASS: scrartcl
neithor of which worked.

putting the latex classes entry in your .emacs is fine.  there's no need
for any other file.  it's just that some of us have so much
initialisation code that we use several files instead of just .emacs.

indeed.  the name given here must match one of the entries in
org-latex-classes, not necessarily the same name as the actual LaTeX
class.  A little confusing, unfortunately.

No luck thus far. I added your code to my .emacs but left the #+begin_src
and #+end_src lines out since I figured they have no purpose in .emacs.

I the altered #+latex_class: article to #+latex_class: komaarticle in my
org-file.
Whe trying to export it I am told komaarticle is not a known Latex class. I
then wrapped that line in #+begin_src org #+end_src which, of course, didn't
work.

The #+begin_src, #+end_src, is to clearly separate the lisp source in
the email (many posters to this list use Org syntax in emails).

Did you restart Emacs after that?

Yes. No better.
And I had restarted emacs after editing .emacs before I started working on
my org-document.

I am a very novice Latex user, so forgive me for asking but do you have 
the KOMA package installed?

correct.  they are org src block delimiters.

What is the value of org-latex-classes?  check this with C-h v when in
the org buffer.  If komaarticle is not one of the entries, your emacs
initialisation was incorrectly implemented.  Note that you probably want
to have that customisation after loading org and ox-latex in particular.

It looks like I don't have an org-latex-classes variable. C-h v
org-latex-classes results
in the message [No match].

Looking into the Warnings buffer of emacs I find:
Warning (initialization): An error occurred while loading
`/home/martin/.emacs':
Symbol's value as variable is void: org-latex-classes

Running emacs --debug-init does not yield any further information.

Kind of puzzling I think since LaTeX works rather well as long as I stay
away from KOMA.

My emacs installation is what comes with Debian stable: 23.4.1
My org-mode version is 8.2.5h.

I've taken the liberty to add some emphasis to Eric's comment: I think
you are trying to set the variable before loading the file where it is
defined.

It is the second to last part of my .emacs file (not counting
custom-set-variables).
The LaTeX call sits just before the KOMA stuff. No ox-latex to be found, I
haven't
needed it so far. Is that maybe...

I have a feeling you are a victim of the infamous mixed install issue.

The output of M-x org-version looks good and going back to the
emacs-supplied
version does not help.

Unfortunately that is not a complete test.  You should compare the
load-path shadows and match them library for library (excluding
libraries that exist in only one of the distributions).

Hope this helps,

Tonight I have been a bit adventurous and I have seen some success.
But before that I tried to understand what lading ox-latex meant and how
to do it. I found something here: http://orgmode.org/worg/exporters/koma
-letter-export.html
and tried it with no luck. Then I thought, org + LaTeX and exporting to PDFworks
just fine as long as I stay away from trying KOMA so ox-latex must work...

Next I looked up org-latex.el in the directory org-mode version 8.2.5h
lives in
my computer and started to study the code. I soon found were
org-latex-classes
are defined and decided to add the code Eric has supplied.

Now komaarticle works!

This indicates to me that ox-latex has loaded just fine all the time and it
is indeed
the one from version 8.2.5h that loads.

So why didn't it work the way I was told to do it?
How much of my .emacs is needed to figure it out, all? Here are the parts I
think
are relevant. First the very beginning of my .emacs (comments are mixed
Swedish
and English):

;;; Martins nya .emacs

(require 'org)

-letter-export.html
;;
;(eval-after-load 'ox-latex
;  '(add-to-list 'org-latex-packages-alist '("AUTO" "babel" t) t))
;;

After this follows many lines of tweaks most of which is copied from
BerntHansen and
none of it related to bable or exporting. This is the stuff I have been
using for a while
and use every day at work.

Then near the end LaTeX and Eric's code (commented out):

;;;
;;;
;;; LaTeX
;;;
(org-babel-do-load-languages
 'org-babel-load-languages
 '((latex . t)))
;;;
;;; KOMA
;;;
;(add-to-list 'org-latex-classes
;               '("komaarticle" "\\documentclass{scrartcl}"
;                 ("\\section{%s}" . "\\section*{%s}")
;                 ("\\subsection{%s}" . "\\subsection*{%s}")
;                 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
;                 ("\\paragraph{%s}" . "\\paragraph*{%s}")
;                 ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))
;;;

So much for Thursday evening.

Fine up to here.  Now what you need to do is (require 'ox-latex)
*before* you try to:

> ;(add-to-list 'org-latex-classes

> ;                 ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))

which is what several of us have been trying to get across!  At the very
least, you need:

,----
| (add-to-list 'load-path ...org lisp directory...)
| (require 'org)
| (require 'ox-latex)
| (add-to-list 'org-latex-classes ...)
`----

to do what you want!  You are missing the third line.

A minimal initialisation with just those four lines should be enough to
see if org with KOMA works.

For your understanding, you can do a simple test.  Start emacs without
the add-to-list line.  Then evaluate these:

  (featurep 'org)
  (featurep 'ox-latex)

You will get t for the first, nil for the second.  

Now try to find the variable org-latex-classes with C-h v.  You will not
be able to find it.  Now load ox-latex with either load-library or by
evaluating (require 'ox-latex).  Try the above evaluations again, you
will see t for both, and when you try to find the variable with C-h v,
you will succeed.

AFAIU, the exporter loads enabled backends when you do the first export.
So when you modify a variable that is defined in an unloaded module, of
course this does not work!  Hope this makes the problem and the
resolution clearer.

To get some hints about doing things right, I would point you to my
setup: <https://github.com/suvayu/.emacs.d/blob/master/org-mode-config.el>

Hope this helps,

First of all: sorry for the previous, empty post. I misclicked.
Further comments below.

Thanks for your patience guys.
You have overestimated my elisp-knowledge.
Telling me I need to call in ox-latex without telling me how was asking too
much
of me. I tried to look it up myself and failed.
Now, finally, this works as adverticed and Suvayu's explanation of how the
exporter
loads backends clears some fog.

I have even got Memoir to work.

Yes, it is easy to assume that people know what we mean.  The trick is
to ask for clarification!

Excellent.  Glad we got there in the end.

Could you post the initialisation you do have?  It's difficult to debug
your case with partial information.  My gut feeling is that you are not
loading org properly and are indeed falling victim to a mixed
installation scenario, as mentioned by Suvayu.

In m experience, you need to load org, then ox-latex and finally
customise org-latex-classes.  If you are not doing this, things won't
work.
