LaTeX export > Avoid \newline command after timestampsX-Draft-From: ("nnimap+mc:INBOX.sncb")

[Francesco Pizzolante]

Hi,

When exporting an Org buffer to latex, I can see that Org generates an extra
\newline command just after exporting the timestamps to the heading.

An example.

This Org stuff:
--8<---------------cut here---------------start------------->8---
*** DONE My Task                                                 :Be:
    SCHEDULED: <2010-03-01 Mon> DEADLINE: <2010-03-05 Fri>
    :LOGBOOK:
    - State "STARTED"    from "TODO"       [2010-03-02 Tue 09:30]
    - State "DONE"       from "STARTED"    [2010-03-02 Tue 10:00]
    CLOCK: [2010-03-02 Tue 09:30]--[2010-03-02 Tue 10:00] =>  0:30
    - PWA.
    :END:
    :PROPERTIES:
    :Effort:   4:00
    :END:
--8<---------------cut here---------------end--------------->8---

Is exported to latex this way:
--8<---------------cut here---------------start------------->8---
\subsubsection{\textbf{DONE} My Task \textbf{:Be:}}
\label{sec-2.2.2}

    \texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:} \textit{2010-03-05 Fri}\newline
--8<---------------cut here---------------end--------------->8---

At the end of the timestamps line, you can see the extra \newline command.

This \newline command should be removed as it adds extra vertical space which
does not respect the document class definition used for the document.

In order to do that, I made the following change to org-latex.el and it works
for me, but I'm not sure my change is completely safe:

--8<---------------cut here---------------start------------->8---
index 03216a8..88bd8c3 100644
--- a/lisp/org-latex.el
+++ b/lisp/org-latex.el
@@ -1511,7 +1511,7 @@ The conversion is made depending of STRING-BEFORE and STRING-AFTER."
       (beginning-of-line 1)
       (unless (looking-at ".*\\\\newline[ \t]*$")
        (end-of-line 1)
-       (insert "\\newline")))))
+       ))))

 (defun org-export-latex-fixed-width (opt)
   "When OPT is non-nil convert fixed-width sections to LaTeX."
--8<---------------cut here---------------end--------------->8---

Is this the right thing to do to avoid this extra \newline command?

Thanks,
Francesco

Hi Francesco,

thanks for this.  The reason why I put this is is to make sure that  
text after that line will start
in a new line, and now flow into the scheduled/deadline line.   For  
example:

*** DONE My Task                                                 :Be:
    SCHEDULED: <2010-03-01 Mon> DEADLINE: <2010-03-05 Fri>
    this should start a new line but does not with your patch

Do you disagree that this is the right thing to do?  Do you know a  
method to achieve the same result without generating extra white space?

We could simply insert a blank line (e.g. "\n\n"), couldn't we?  This
would let LaTeX start a new paragraph if there's no space between
scheduled/deadline line and do no harm if there is, because LaTeX
doesn't care about multiple newlines.

Yes, we could, but what I tries was to *not* start a new paragraph...

Why not? From my point of view, the timestamps are more technical information
and the text you have after is the "real" text regarding the heading, so why
not put them on separate paragraphs?

After a few more tests, I think that David's suggestion is the best one:
having a simple blank line after the timestamps in the generated LaTex code.

This way, if we have some text in the heading, LaTex will simply start a new
paragraph and we will have the correct spacing. If don't have text in the
heading, LaTeX will simply ignore the blank line and will format the next
heading according to the document class chosen.

The problem with the actual implementation is that it forces a newline in all
cases (both if you have text in the heading or not) which does not respect the
document class formatting that you've chosen.

What do you think?

Thanks a lot,
Francesco

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.

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.

I hope, the problem is clearer now.

Please let me know what you think.

Francesco

Yes, sorry, my brain's logical unit misfired.  What I meant was

,----
| (unless (or (looking-at ".*\n[ \t]*\n") (looking-at ".*\\\\newline[ \t]*$"))
`----

Translating to: insert /no/ \newline, if either (a) there is a empty
line beneath this line or (b) there is already a \newline.  Using this
the examples give:

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---
\section{STARTED  First}
\label{sec-1}

   \texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:} \textit{2010-03-19 Fri}
--8<---------------cut here---------------end--------------->8---

No extra vertical space between this heading and the next one.

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---

Gives the following:

--8<---------------cut here---------------start------------->8---
\section{STARTED  Second}
\label{sec-2}

   \texttt{SCHEDULED:} \textit{2010-03-01 Mon} \texttt{DEADLINE:} \textit{2010-03-19 Fri}\newline
   This task is split among all services and communication between the
   entities.
--8<---------------cut here---------------end--------------->8---

This would be Carsten's case.

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---

Gives the following:

--8<---------------cut here---------------start------------->8---
\section{\textbf{DONE} Third}
\label{sec-3}

   \texttt{DEADLINE:} \textit{2010-03-26 Fri}

   This task is split among all services and communication between the

   Second paragraph.

   fdqsfdq

What you expected.

IMO inserting a \newline after the deadline/scheduled line if text follows
immediately (example 2) makes sense.

We're going ahead! ;-)

Your intention is also clearer for me now.

Examples 1 and 3 are OK. I still have a remark for example 2.

Yes, it is. ;-)

I'm just wondering why having a special handling for this case (the second
one). Adding a simple blank line instead of the \newline command would be
cleaner as it you would totally rely on LaTeX for the formatting.

In addition, we keep having 2 different behaviors: in example 2, the text
starts on a newline (but on the same paragraph as what comes before) while on
example 3, the text starts on a new paragraph.

See the attached picture which shows clearly the difference between the text
of section 1.2 and the text of section 1.3: for this example, I simply use the
default article formatting which uses paragraph indentation except for the
first paragraph of sections.

From my point of view, both examples 2 and 3 should be exported the same way:
it should not matter if we have (or not) an empty line in the Org buffer between
the heading and text. While, in the LaTex code, we should always add blank
line instead of \newline commands. LaTeX will thus always put things on
separate paragraphs, which totally makes sens to me.

Does all this make sense to you?

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.
