[Docutils-users] LaTeX writer crash

[Mikołaj M. <mi...@wp...>]

Below traceback, OS info and docutils version. HTML export works without problems. Note that I have long list of empty (so far) hyperlinks - maybe that is the cause?

File itself in attachment. Command
rst2latex.py 01.txt 01.tex

Dear Mikołaj,

thank you for the bug report.

I get 160 errors of type

  /tmp/01.txt:28: (ERROR/3) Unknown target name: "02.08.06".
  
here.

No. A minimal example for the problematic input is::

  Epiroci zaprosili na tron Alketasa [180]_, ...

  .. [180] R. 312

which produces the pseudo-XML::

<document source="/tmp/test02.rst">
    <paragraph>
        Epiroci zaprosili na tron Alketasa 
        <footnote_reference ids="id1" refid="id2">
            180
        , …
    <footnote backrefs="id1" ids="id2" names="180">
        <label>
            180
        <enumerated_list enumtype="upperalpha" prefix="" start="18" suffix=".">
            <list_item>
                <paragraph>
                    312

i.e. The text R. 312 is parsed as the first item of an enumerated list,
which is surely not what you intended and looks strange in HTML, too.
see http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#enumerated-lists

You can avoid this by escaping::

  Epiroci zaprosili na tron Alketasa [180]_, ...

  .. [180] \R. 312


However, for footnotes that start with anything that is not a paragraph,
the problem remains:

I changed the code to be more stable for these cases, found a follow-up bug
and fixed as well and will upload the fix to the repository soon.

Thanks,

Günter

It should work now with revision 7904 of the SVN repository.
