Re: Bug Report

Hello Robert,

thank you for your bug report.
Yes, you are completely right, the implementation of the shift
paragraphs  >  and  <  is not correct.

It works for simple lists, but you get into trouble with nested
lists, especially if the last list item is not on top level, for
example a list like

   * Item 1 of outer list
   * Item 2 of outer list
     o  item one of inner list
     o  item two of inner list (and that's it!)

In HTML this woud be implemented as

   <ul>
   <li> Item 1 of outer list
   <li> Item 2 of outer list
     <ul>
     <li>  item one of inner list
     <li>  item two of inner list (and that's it!)
     </ul>
   </ul>


The problem is, as you pointed out, that the parser does not allow
a <  (shift back) at the end of a list. Sublists cannot be placed
at the end of a list. At least one item should come after the
sublist. In pp2html I tried to keep track of the level and to
rewind the indentation level by adding an appropriate number of </ul>.
In pp2latex the implementation is totally buggy (it just ignores
sublists).

It think that the parser should be changed so that the following
PerlPoint code would be correct:

    =Background

    *Blah

    *Blah

    *A Sublist

    >

    *Foo

    *Bar

    <

    Some thing else

The first *Blah starts a (toplevel) list. The > starts a second level
list (and does not terminate the toplevel list)
The < should terminate the second level list and the "Something else"
(which is a normal text paragraph) terminates the toplevel list.

Probably the Parser should implement a stack of lists.
Another problem is the continuation of numbered lists, which may be
interrupted by an example (verbatim) block.

I will discuss this further with Jochen, who knows the details about
the parser. Hopefully we will soon come up with a solution.

Reards,

  Lorenz
