LaTeX export - can't skip a heading level

LaTeX export - can't skip a heading level

[Richard Stanton]

Using org-mode 7.8.03, I've found that exporting to LaTeX has a tough time
if you try to skip a header level. For example, to prevent my TODO items
being numbered, one method is to make them a lower-level heading, and then
make that level un-numbered.

However, if I try the following:

* To Do List
*** TODO First item
*** TODO Second item

Then when exported to LaTeX, only the title appears (both TODO items are
excluded).

I tried make the first title one level lower, like this:

** To Do List
*** TODO First item
*** TODO Second item

* Next Section

Now the TODO list exports, though it now treats ** as the section header,
so it hasn't solved that problem, and moreover, the next section is
omitted entirely.

TODO items as part of an itemized list?

[Richard Stanton]

To save space in LaTeX exports and also to stop my TODO items being
numbered, I'd like to have TODO items as part of a list, e.g.,

- TODO Item 1
- TODO Item 2

However, while this prints OK, these entries are ignored by org-mode when
I ask it to create a TODO list. Is there any way to do what I want?

Thanks.

No, because you are mixing to different things: lists and TODO items.

TODO items start with "*".

You can convert 

* TODO item 1
* TODO item 2

to a list by selecting the region they are in, then doing C-u C-c -

You can convert a list to TODO items with C-u C-c *

[Richard Stanton]

Makes sense. I realize I can achieve almost all of what I want by making
my TODO items, say, level three headers, "***", then not including
\subsubsection in my latex_class definition. Now each TODO item is printed
in LaTeX as a separate \item in an itemize list, just as I wanted.

Just one remaining problem, however. The exporter inserts a hard
line-break, "\\" after the first line of each of these \item entries. This
is fine when there is additional text for that item, but if the TODO item
is just one line, this results in unwanted extra white space being
inserted between the \item entries.

Yes - unfortunately it is hardwired (line 1321 of org-latex.el).
AFAICT, there is no good reason for it to be included, even with
additional text for the item: if one wants it, then adding one
explicitly to the org file works (although the other exporters might not
like that). BTW, the html exporter also adds a hardwired <br/>.

I fixed the LaTeX exporter, it only includes the additional \\ when the
subtree has some content.

Thanks Richard for reporing this.

Have you tried org-export-headline-levels ?

Does this do what you want?

--8<---------------cut here---------------start------------->8---

#+OPTIONS: num:1

* To Do List
** TODO First item
** TODO Second item
--8<---------------cut here---------------end--------------->8---

PS. Not sure why the third level headlines are skipped if the second level
headline is absent. This feels like a bug to me.

Not quite, I don't think, as it removes numbers from *all* second level headers.

The latex exporter is very rigid about what it will accept: it wants the
levels to be in strict sequence. So this has to be chalked down as a
fairly deeply ingrained limitation of the exporter. I don't see an easy way
to lift it.

Especially as this is a limitation of LaTeX, not the exporter.

Not true - the following compiles with no problems:

--8<---------------cut here---------------start------------->8---
...
\begin{document}

\maketitle

\setcounter{tocdepth}{3}
\tableofcontents
\vspace*{1cm}

\section{foo}
\label{sec-1}

\subsubsection{baz}
\label{sec-1-1-1}
\subsubsection{hunoz}
\label{sec-1-1-2}

Yes, LaTeX doesn't really enforce it, but it makes the assumption of
"correct nesting".  It's been a few years since I tried something like
you've posted, but I've quickly learned that funny things happen when
your document grows to a more realistic size (it had to do with how the
counters are interacting).  So I've stopped doing it and have never
looked back.  If you must, you can provide your own sectioning commands
in LaTeX that handle this situation more gracefully, but that's really a
bit much to ask of an org exporter, don't you think?

Certainly - I did not argue that the exporter should do this. I just
pointed out its limitation and that the limitation would be tough to
lift.
