Re: [Python-markdown-discuss] GSoC progress

[Artem Y. <ne...@gm...>]

I reformatted test suite, fixed a lot of bugs in version with 
ElementTree, and now all the test are working.

I changed hrs handling because in NanoDOM version top level hrs 
surrounded with p tags, and p tags was stripped out in toxml method. Now 
LinePreprocessor replaces all hrs declarations with "___", then I added 
Markdown._processHR method, and in Markdown._processSection we now also 
checking for hr. But I also was forced to add this check to 
Markdown._processParagraph.
Maybe the simplest and faster  way of fixing it is just plain replace 
all "<p><hr /></p>" with "<hr />" after serialization, but then, we 
won't get valid ElementTree.

Concerning attributes({@id=1234}), that was handled by NanoDOM, I added 
global function handleAttributes(text, parent), because it's required in 
inline patterns(ImagePattern) and also in Markdown class. Now we 
processing attributes in Markdown._processTree, after applying inline 
patterns, but still in same cycle.

New version is slower then previous because of these changes, but still 
faster then new version with NanoDOM.

I also fixed ticket #5 [1] in GSoC etree branch. Changing order of 
inline patterns works, but then other tests will fail. I changed 
BACKTICK_RE, to r'[^\\]\`([^\`]*[^\\]{0,1})\`' , after that evrything 
works fine, except of striping last character before backtick, for 
instance, "test `test`" -> "test</code>test</code>" instead of "test 
</code>test</code>", it's because of negative expression([^\\]) at the 
begining of regexp, so I decided to add to Pattern class attribute 
contentGroup, representing number of group, that we'd like to replace, 
by default it equals to 2. And changed regexp to 
r'([^\\])\`([^\`]*[^\\]{0,1})\`', so now we should use group 3 instead 
of group 2, and we creating pattern in that way: 
BacktickPattern(BACKTICK_RE, 3), joined group 1 and group 2  will be the 
string to the left of the match.
