[PATCH] Suppress extra newlines around source code in LaTeX export

[PATCH] Suppress extra newlines around source code in LaTeX export

Hi,
title says it all.

A single paragraph such as:

#===
Dura lex
#+begin_src emacs-lisp
(a)
#+end_src
sed lex
#===

should remain entire in the LaTeX export.

Hi,

attached is a second patch which suppresses some other extra newlines
in the LaTeX export. Let me know if  you need any explanation.

Hi Nicolas,

I need additional information with respect to this patch:

I have fixed this part, in a different way though.

Why would you like to remove the "\\" as well?  When itemize lists are  
used to format headlines, I think there should be a line break after  
the end of the original headline.  Otherwise the text below the  
headline will flow into the headline.  Or am I missing something here?

What is the problem with additional empty lines before \\title  
command.  Does that really change anything in the output?

Thanks.

I'm afraid there are still extra paragraphs resulting from an extra
newline after code blocs.

Consider the following test chunk:

#=====
This is a new paragraph
#+begin_src emacs-lisp
(setq ispell-program-name "aspell")
#+end_src
continuing after the code bloc.
#=====

Using the freshest code, is is translated to

%=====
This is a new paragraph
\lstset{language=Lisp}
\begin{lstlisting}
(setq ispell-program-name "aspell")
\end{lstlisting}

continuing after the code bloc.
%=====

Unfortunately this problem remains: processing

#=====
This is a new paragraph
#+begin_src emacs-lisp
(setq ispell-program-name "aspell")
#+end_src
continuing after the code bloc.
#=====

still inserts an extra newline just before "continuing (...)".

Actually,  I cannot reproduce this problem - I do not see the extra  
newline.

Hi Carsten,

you're absolutely right, I performed yet another git pull and couldn't
reproduce this either. Great !

Now, speaking of extra newlines, I'm puzzled about this: at some stage
(which I didn't identify yet, maybe when exporting to LaTeX), Org adds
an ID property to some headings in my document ; that is, for
instance,

* Aa
  * Bb
    Text

becomes

* Aa
  * Bb
    :PROPERTIES:
    :ID: fa489059-d27e-47fb-929d-8ca9c749d079
    :END:

    Text


Notice the extra newline between :END: and Text. It's all good except
when exporting to LaTeX *and* the concerned heading is to be treated
as an item.
I've been thinking a bit about this special case ; and it seems to me
like, on one side, the extra newline should remain, and on the other
side, empty lines following a heading should be ignored by the LaTeX
translator when this heading is translated into an item.
What do you think ?

I do agree and have tried to fix it.  Please verify.

I think you're right ; I may have been abused by what Adobe Reader
displayed when performing my tests, as I just discovered that, for
whatever reason, it doesn't always reload the pdf file when using
<Ctrl-r>

Using this test document

#===========
* Level 1

** Level 2

*** Level 3

**** Level 4
Text
#===========

the current code produces

%==========
\begin{itemize}

\item Level 4\\
\label{sec-1.1.1.1}

Text
%==========

There's an extra space produced by the \label{} because there's no '%'
at the end of it ; another solution is to move the \label before the
\\
There's also an extra newline before "Text".
Please find attached my second proposal to fix this.

It's not really a problem, it just seems to me like, the less extra
'\n' you see in the output of a LaTeX code generator, the more
confident you can be.

Actually I do remember why I considered removing the '\\' : take this document:

#=============
 Level 1

** Level 2

*** Level 3

**** Level 4
- itemized
- list
#=============

Since "Level 4" is expressed as an item, the only way of getting the
correct output is *not* to have any '\\' between "Level 4" and
"itemized". That is, in LaTeX, not to have '\\' between
  \item Level 4
and
  \begin{itemize} \item itemized \item list \end{itemize}

I prefer to write

    \label{...}%

if you can agree to that.
