[Python-markdown-discuss] GSoC current progress

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

I deleted Pattern.contentGroup attribute, that I previously added, 
because I solved this problem using regexps. I also created new regexp 
for links, it partly solves ticket#4 because it works fine, until you'll 
try to insert nested parenthesis in link, in Perl  implementation it's 
solved with recursive  regexp, but I don't see any way of doing it in 
Python using regexps.

Perl code:
$g_nested_parens = qr{
    (?>                                 # Atomic matching
       [^()\s]+                            # Anything other than parens 
or whitespace
     |
       \(
         (??{ $g_nested_parens })        # Recursive set of nested brackets
       \)
    )*
}x;

Now link regexp works for angled links too, so I deleted 
LINK_ANGLED_PATTERN from patterns list. Now link regexp is quite 
complicated, so what about of using re.VERBOSE flag? I tried it without 
any changes to regexps, but it's not working, seems that Python goes to 
infinite loop after adding this flag.
Also I created aggregated regexp for STRONG_RE and STRONG_2_RE and 
aggregated regexp for STRONG_EM_RE and STRONG_EM_2_RE. So STRONG_2_RE 
and STRONG_EM_2_RE can be deleted form patterns list.

Now I'm gathering different issues/bugs, I think I'll post it on Monday 
for discussion, which of them we want to fix.
Another thing I plan to do - port extensions to ElementTree.
Maybe some refactoring. For instance class CorePatterns scheduled for 
refactoring, but now I don't have an idea what can be a better 
replacement for it.
