Hi David,

Took me a while to realize the problem with current implementation:
If
you already have a blank line between scheduled/deadline line and the
content the newline forces extra spacing between scheduled/deadline
and the following paragraph.
I'm sorry if I wasn't clear enough.
This cleary /is/ problem. Maybe we should catch these two cases
(patch attached):
,----
| (unless (and (looking-at ".*\n[ \t]*\n") (looking-at ".*\\\
\newline[ \t]*$"))
`----
Insert \newline only if there is no paragraph separator. As far as I
can see the LaTeX code is already rendered when
`org-export-latex-keywords' is called so this should work out.
I tried your patch, but I still get extra \newline commands in the
generated
LaTeX.
Let's go back to examples, I think it will be easier to understand
my problem.
1) Heading with no text
--8<---------------cut here---------------start------------->8---
** STARTED First
SCHEDULED: <2010-03-01 Mon> DEADLINE: <2010-03-19 Fri>
--8<---------------cut here---------------end--------------->8---
Gives the following:
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{STARTED} First}
\label{sec-1.1}
\texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:}
\textit{2010-03-19 Fri}\newline
--8<---------------cut here---------------end--------------->8---
Which gives me an extra vertical space between this heading and the
next one.
While I would expect this (with or without the extra blank line in
this case,
as there's no text after):
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{STARTED} First}
\label{sec-1.1}
\texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:}
\textit{2010-03-19 Fri}
--8<---------------cut here---------------end--------------->8---
2) Heading with text and no blank line between heading and text
--8<---------------cut here---------------start------------->8---
** STARTED Second
SCHEDULED: <2010-03-01 Mon> DEADLINE: <2010-03-19 Fri>
This task is split among all services and communication between the
entities.
--8<---------------cut here---------------end--------------->8---
This gives the following:
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{STARTED} Second}
\label{sec-1.2}
\texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:}
\textit{2010-03-19 Fri}\newline\newline
This task is split among all services and communication between the
entities.
--8<---------------cut here---------------end--------------->8---
I also get an extra vertical space between the timestamps and the
text which
is on a new paragraph.
Instead, I was expecting this:
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{STARTED} Second}
\label{sec-1.2}
\texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:}
\textit{2010-03-19 Fri}
This task is split among all services and communication between the
entities.
--8<---------------cut here---------------end--------------->8---
3) Heading with text and blank line between heading and text
--8<---------------cut here---------------start------------->8---
** DONE Third
DEADLINE: <2010-03-26 Fri>
This task is split among all services and communication between the
entities.
Second paragraph.
fdqsfdq
--8<---------------cut here---------------end--------------->8---
This gives the following:
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{DONE} Third}
\label{sec-1.3}
\texttt{DEADLINE:} \textit{2010-03-26 Fri}\newline
This task is split among all services and communication between the
entities.
Second paragraph.
fdqsfdq
--8<---------------cut here---------------end--------------->8---
In this case, again, I get an extra vertical space between the
timestamps and
the text which is also in a new paragraph.
Instead, I would simply expect this:
--8<---------------cut here---------------start------------->8---
\subsection{\textbf{DONE} Third}
\label{sec-1.3}
\texttt{DEADLINE:} \textit{2010-03-26 Fri}
This task is split among all services and communication between the
entities.
Second paragraph.
fdqsfdq
--8<---------------cut here---------------end--------------->8---
As you can see from these 3 examples, it is safer to always generate
blank
lines only instead of \newline commands.
Sorry for the length of this message.
On the contrary, thank you for this long message. This is exactly
what nails
the discussion and shows the problems.
I agree with what I think is the conclusion of this discussion: No
\newline,
only an empty line to star a new paragraph, in all three example cases.
I have made this change now, thank you both.
