[Python-markdown-discuss] Cannot serialize error in custom block processor

[Trent \TiZ\ M. <twi...@gm...>]

Hi. I'm trying to create an extension for Markdown to support the custom 
HTML tags used in Dedalus, an interactive fiction system. I have the 
inline stuff working perfectly fine, but I want to create a custom block 
type for the <page>, <paragraph>, and <object> blocks it uses. I figured 
an intuitive way to handle that would be to indent the contents.

The code I have written so far to try and accomplish this is here: 
http://pastebin.com/4pVhzeqW Right now, it dumps the following stack trace:

Traceback (most recent call last):
   File "./markded.py", line 81, in <module>
     """)
   File "/usr/lib/python2.7/site-packages/markdown/__init__.py", line 
300, in convert
     output = self.serializer(root)
   File "/usr/lib/python2.7/site-packages/markdown/serializers.py", line 
276, in to_xhtml_string
     return _write_html(ElementTree(element).getroot(), format="xhtml")
   File "/usr/lib/python2.7/site-packages/markdown/serializers.py", line 
198, in _write_html
     qnames, namespaces = _namespaces(root, default_namespace)
   File "/usr/lib/python2.7/site-packages/markdown/serializers.py", line 
264, in _namespaces
     add_qname(key)
   File "/usr/lib/python2.7/site-packages/markdown/serializers.py", line 
244, in add_qname
     _raise_serialization_error(qname)
   File "/usr/lib/python2.7/site-packages/markdown/serializers.py", line 
78, in _raise_serialization_error
     "cannot serialize %r (type %s)" % (text, type(text).__name__)
TypeError: cannot serialize <built-in function id> (type 
builtin_function_or_method)

What am I doing wrong that is causing this error to occur? I'm not a 
good Python programmer by any stretch of the imagination, and I imagine 
my code is probably pretty horrible. I'm sure I am going about this 
completely wrong, and I'm sure that's related to why I'm getting this error.

Thank you for your time.
