I've found a bug in pp2latex.
The code....
=Background
*Blah
*Blah
*A Sublist
>
*Foo
*Bar
*Wub
Generates
\section{Example}
\begin{itemize}
\item Blay
\item Blah
\item A Sublist
\end{itemize}
% Shift >
\begin{itemize}
\item Foo
\item Bar
\item Wub
\end{itemize}
Note that the outer "itemize" is incorrectly ended, so the
inner list is not a sublist, but appears to be a continuation.
I've had a quick look, and the problem looks horribly
deep inside PerlPoint. It looks to me that the document
is being parsed and fed to the backend as...
ListItem....
ListItem...
--> EndList
Shift
BeginImisedList
ListItem...
I believe the problem is in the "EndItemize".
The natural interpretation of ">" is "start a sub-list of this item".
And the fact that you can only use it within a list re-inforces
this idea somewhat.
And if you planted a new "list start", this is what both HTML and
Latex would do. And since Latex works very hard to get spacings
right, telling it to do a sublist is the "right thing to do".
But once the parser has signaled the end of the outer list,
">" collapses to just "move over a bit".
pp2html does this by opening
a null <UL>, and keeping track of how many "bits" it has moved
over, so it can unwind the right amount at the right time.
And pp2latex simply ignores it --- for, I suspect, because almost
any way of telling LaTeX to start "moving over a bit" will fail
horribly unless there is a corresponding something to tell it to stop.
And that is tricky if
the indented list happens to be the last thing on a slide/page,
there won't be a corresponding "<" (the parser prohibits it), thus
obliging the back end to keep track of indentation. AAAAARGH!
I've fudged soemthing in pp2latex that does the minimum
I need, but it is a hack. Someone should sort this properly!
