ox-koma-letter: how to use @@LaTeX:@@ specific commands in #+ directives

ox-koma-letter: how to use @@LaTeX:@@ specific commands in #+ directives

[Eric S Fraga]

Dear all,

I have started using ox-koma-letter from the contrib directory.  Very
nice.  Thanks Nicolas, Alan, Viktor, and Rasmus!

Everything works well so far except for one minor niggle: I would like
to introduce, sometimes, LaTeX specific inline directives in #+
lines.  E.g. for LaTeX export, I would use @@latex:\\@@ to get a line
break in a title or author entry.  I had expected the same to work with
ox-koma-letter given that it is a latex /derived/ backend and does work
in normal text, just not in #+ lines.

I guess the processing of #+ lines is handled directly by ox-koma-letter.

Would it be possible to extend @@...@@ processing to those lines?  Or am
I doing something silly?

Thanks,
eric

It also doesn't work with ox-beamer:

#+subtitle: subtitle @@latx:\LaTeX@@ @@beamer:BEAMER@@

I guess it's a feature.  Or a bug at a higher level than ox-koma-letter.

You can use the koma-letter snippet:

  #+subject: test @@koma-letter:\LaTeX@@

You can use a macro to combine several snippet types (not tested):

#+macro: latex @@latex:$1@@@@beamer:$1@@@@koma-letter:$1@@

I cannot reproduce it. koma-letter back-ends explicitly allows latex
export snippets, e.g.,

  #+title: @@latex:\something@@

produces the expected \something.

This is a feature. 

If @@latex:...@@ is supported in beamer export, you have no way to
insert latex-only code in a document that you plan to export using both
beamer and latex back-ends.

However, this doesn't apply in koma-letter.

I agree.  I cannot reproduce either.  Typo.  Thanks.

Ummm, I thought I was going crazy as, for once, I had tested using emacs
-Q before posting something silly to the list...

You are correct in that it works with #+title:.  It also works with
#+subject:.  However, it does *not* work with #+author:.  I've not tried
any of the other org setting directives.  It was author I was playing
with yesterday...

thanks,

Right.  #+author is not parsed.  In the patch I enable parsing on this and
others.

Nicolas: are there any of the keywords in the patch that shouldn't be
parsed?

Also, I left out FROM_ADDRESS as I remember it interprets newlines and I
don't have time ATM to properly check if this depends on the newline
behavior.

Rasmus,

with this patch, exporting to koma-letter doesn't work for me.  I've not
investigated properly yet but thought I'd give you a heads up on
this.  The LaTeX compilation fails:

,----
| Foot of first page
| Address (addressee)
| Location field: empty
| Title: yes

| l.59 \closing{nil}
`----

Without the patch, the compilation succeeds (although obviously I still
don't have @@latex:@@ working in the author field ;-).

Thanks,
eric

Thanks.  I don't really know where exactly it breaks with a minimal
example.  It works on my PC.  Anyway, this patch adds only a few parsed
keywords.  Does it work with your letter?

Strange thing: exporting to pdf (C-c C-e k p) does not work but
exporting to LaTeX (C-c C-e k l) and then running pdflatex on the LaTeX
works just fine.  I've tried playing with org-latex-pdf-process to no
avail, noting that ox-koma-letter uses org-latex-compile.

Something has changed along the way and I don't know what it is.  I'll
investigate further.

thanks,
eric

This works fine.  Both with emacs -Q and with my customisations.  Not
sure what was happening earlier but I must have got something out of
synch somewhere.

I don't think so.

Notwithstanding AUTHOR, which clearly is an overlook (ox.el parses it),
I wonder if it is a net gain, tho. In my experience, these values are
mostly constituted of LaTeX code anyway (e.g., \vspace and \hspace in
signature) and this change will not make them simpler.

Indeed, `parse' treats newline characters as spaces, so it is not
a replacement for `newline'.

Note that SIGNATURE has the same problem.
