handling paragraphs as long lines

IMHO one of the weakest points in MoinMoin is how wiki.py parses the
input. Using regular expressions simply doesn't work properly for
nested balanced expressions, and we have already far too many
exceptions which nested expressions work, and which not.

What do you think of using a completely different paradigm, namely to
do bison-like parsing of the input data to get the appropriate tokens?

To use a solution in pure Python the following looks very promising:

BTW, is any other part of MoinMoin dependent on wiki.py? I mean, can
I simply replace the HTML generating engine with a different one,
similar to the `colorizing' parsers for other languages like C or C++?
Where can I find the documentation of the affected interface?

Hi Werner,

One of the problems might be that you don't want to be as strict in a
wiki as you want to be when parsing a programming language.

E.g. there never should be a "syntax error" in a wiki.

Maybe don't touch wiki.py for starting. Just call it wiki2.py and use
#format wiki2 in your page header (like already possible for rst and
other stuff).

Maybe reading wiki.py is the best and most current "documentation".
It is important to use the formatter to generate output.

greetings, Thomas
