I'm curious as to why you're replacing it. There don't seem to be
very many options from the lack of response to this thread:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/82b3b24af35bdba0

Pyreverse is probably going to be my next stop to investigate, but I
don't know how it compares to PyNSource

ArgoUML uses the ANTLR Java grammar. ANTLR is usable from most
languages.

There are some differences in the way the code is handled I thought. At least PyNSource seems like a dead project now.

Some comparison needs to be done. I agree.

Antlr is just a parser (like Yacc and Bison). If someone already implemented a parser for Java, that would be great :)

Umm, thanks for the CS101 lesson (I think), but that's why I wrote the
"Java grammar" for ANTLR. ANTLR parser + ANTLR Java grammar == parser
for Java. (ie your "great")

Here are some direct links which will save you having to use a web
search engine:

I see Antlr is capable of producing Python code. I did not consider
that option :S
(note to self: I should first check before answering)

On their site they show a lot of grammars it seems. Hmm..

Thanks. Indeed that could save a lot of time.

:)

Thanks. This is worth looking into for sure!

FYI, last commit is only 6 days old.

And, BTW, congratulations for this nice piece of code.
