Bug: LaTeX export and LaTeX environment

Bug: LaTeX export and LaTeX environment

[Ulf Stegemann]

With

Org-mode version 6.36trans (release_6.36.80.gbdfd)
GNU Emacs 24.0.50.3 (i686-pc-linux-gnu, GTK+ Version 2.18.6)

the LaTeX exporter seems to cease to work when encountering a LaTeX
environment. Suppose this minimal org file:

--8<--------------------------snip-------------------------->8---

#+TITLE: Wrapping in Env

/foo/

#+BEGIN_LaTeX
\begin{center}
#+END_LaTeX

/bar/

#+BEGIN_LaTeX
\end{center}
#+END_LaTeX

/baz/

--8<--------------------------snap-------------------------->8---

When exported to LaTeX the relevant part looks like this:

--8<--------------------------snip-------------------------->8---

\emph{foo}

\begin{center}

/bar/

\end{center}

\emph{baz}

--8<--------------------------snap-------------------------->8---

As far as I can see, this happens only if an environment is defined in
the BEGIN/END_LaTeX blocks. Everything between such blocks is exported
literally. I'm pretty sure this once had worked but I'm not sure when
org stopped to export correctly.

I must have been blind, thanks for the pointer! It works like a charm
with org-special-blocks.

I have not looked into the contrib directory lately (for quite a while,
actually) so was not aware of the org-special-blocks stuff.  This is
pretty cool and *almost* what I was about to ask for as well.

The only problem I have with it is I need (for specific environments) to
pass a parameter to the \begin{xxx} call on latex export.  I think what
is there is a more than adequate basis for what I am looking to do and I
will add my stuff to it and try it out.

My question is:  Is there a preferred way of doing this?  I can do a
local enhancement that hard-codes what I am trying to do but would
prefer to do this is a more open-ended (even elegant) way.  At the
end of the day it simply has to work.  But I would prefer doing it
"right." :)

Hi Mark,

several environments already to accept parameters, and in all cases it  
is
done by just listing the arguments after the begin statement,  
separated by spaces.

So what you could implement is that if a user writes

#+begin_xxx {aa}[bb]{cc}

that org-special-blocks will then create

\begin{xxx}{aa}[bb]{cc}

I think we must ask for the space, to make sure that all old code will  
work.
A patch to org-special-blocks for this goal would be very useful, I  
think.

Hi Carsten,

I actually needed this yesterday, so I'll make a patch and try to send
it in the next couple of days.

Should anything be done for the HTML exporter if there are arguments?

Cheers,
Chris

Hi Chris

I can't think of anything useful - unless we do something like

#+begin_xxx -largs "{aa}[bb]{cc}" -hargs "aa=\"xxx\" bb=\"uuu\""

and then use the largs for LaTeX and the hargs as additional attributes
in the HTML div.

But right now I don't see many applications for this in HTML, so
I am not sure it is worth the trouble.  Maybe just ignore these  
additional
arguments, or put them as a string into some special attribute like

<div class="xxx" latex_block_args="{aa}[bb]{cc}">

so that some javascript hacker can do something with these
arguments.

I am not sure what the right cause of action is, and I would
be happy already with a patch that attaches the rest of the line
in LaTeX and throws it away in HTML.

I am starting to think we should have this package in the
core - can I get you to sign the papers with the FSF for
your contributions to Org-mode?  Instructions are here:

Here is the patch for the LaTeX exporter.  I'm not much of an HTML
person, so I don't know if arguments would be useful there.

Wow!  I had hoped to start looking at this over the long weekend
but had other things grabbing my attention.  Now Chris has already
submitted a patch for it!

Chris, I take it that the following:

   #+begin_refquote {Albert Einstein}
   Make things as simple as possible, but no simpler.
   #+end_refquote

would then translate into:

   \begin{refquote}{Albert Einstein}
   Make things as simple as possible, but no simpler.
   \end{refquote}

This is exactly what I was looking for.

Mark

That's the idea.  If it doesn't work, let me know. :)
