[Python-modules-team] Bug#991917: python3-wikitrans: Wiki 2 html conversion errors

[Erich Schubert]

Package: python3-wikitrans
Version: 1.3-1
Severity: important
Tags: upstream
X-Debbugs-Cc: gray at gnu.org

Unfortunately, the wikitrans package fails to convert wiki to html quite 
often.

Here are some errors I noticed when processing the Simpsons fandom wiki:

1. This upstream patch should be included in the package:

https://git.gnu.org.ua/wikitrans.git/commit/?id=c785e3ad767b12a13ae75a3513ec88a4d1144210

2. A wrong variable name is used here:
File "/usr/lib/python3/dist-packages/wikitrans/wikimarkup.py", line 662, in
parse_ref
list.append(self.parse_tag(tok))
TypeError: descriptor 'append' for 'list' objects doesn't apply to a
'HtmlTagNode' object

Here, `list` is the standard class, the instance apparently was renamed to
`seq` in some places. Looks like a copy and paste error to me, as in other
location the local variable is named `list`.

https://git.gnu.org.ua/wikitrans.git/tree/wikitrans/wikimarkup.py?id=c785e3ad767b12a13ae75a3513ec88a4d1144210#n662

3. WikiDelimNodes (generated by wikimarkup: ''Example'') cause raw JSON 
to be
inserted in the HTML:

{"content": "''", "type": "DELIM", "wikinode": "WikiDelimNode"}

A simple workaround (but not a proper solution) is to override the __str__
method as follows:

wikitrans.wiki2html.WikiDelimNode.__str__ = lambda self: ""

Alternatively, one could return `self.content`, but a proper solution 
would be
to generate opening and closing em and bold tags I guess; but I am only
interested in the text, so this hotfix works for me.
