Hi all, I need to do syntax parsing of simple naturual languages,
for example, "weather of London" or "what is the time", simple
things like these, with Unicode support in the syntax.
In Java, there are JavaCC, Antlr, etc. I wonder what people use
in Python? Antlr also has Python support but I'm not sure how good
it is. Comments/hints are welcome. 20 1866

There are several options. I personally like spark.py, the most common
answer is pyparsing, and don't forget to check out NLTK, the natural
language toolkit.

Antlr seems to be able to generate python code, too.

Antlr can generate Python code.
However, I don't think a parser generator is suitable for generating
natural language parsers.
They are intended to generate code for computer language parsers.
However, for examples on parsing imperative English sentences, I
suggest taking a look
at the class library for TADS 3 (Text Adventure Development System)
<http://www.tads.org>
The lanuge has a syntax reminding of c++ and Java.

Thanks for all the replies!
SPARK looks promising. Its doc doesn't say if it handles unicode
(CJK in particular) encoding though.
Yapps also looks powerful: http://theory.stanford.edu/~amitp/yapps/
There's also PyGgy http://lava.net/~newsham/pyggy/
I may also give Antlr a try.
If anyone has experiences using any of the parser generators with CJK
languages, I'd be very interested in hearing that.

I'm going to echo Tommy's reply. If you want to parse natural language,
conventional parsers are going to be worse than useless (because you'll
keep thinking, "Just one more tweak and this time it'll work for
sure!"). Instead, go look at what the interactive fiction community
uses. They analyse the statement in multiple passes, first picking out
the verbs, then the noun phrases. Some of their parsers can do
on-the-fly domain-specific spelling correction, etc, and all of them can
ask the user for clarification. (I'm currently cobbling together
something similar for pre-teen users.)
Thanks for the suggestion. I understand that more work is needed for natural
language
understanding. What I want to do is actually very simple - I pre-screen the
user
typed text. If it's a simple syntax my code understands, like, Weather in
London, I'll
redirect it to a weather site. Or, if it's "What is ... " I'll probably
redirect it to wikipedia.
Otherwise, I'll throw it to a search engine. So, extremelyl simple stuff ...

I use Parsing.py. I like it a lot, probably because I wrote it. http://www.canonware.com/Parsing/

Hi all,
I need to create a parser in C++ which should parse a somewhat complex
file structure. Yeah, it would be possible to write it from scratch in
C++ however I think it would be easier and the end-result would
probably be more efficient if I use a parser generator. However, I only
know flex/bison from a project in C along time ago. Any ideas on what
to use nowadays and for C++ would be nice.

For a research project, we're looking for a reliable parser for C
that will take an ANSI C program and yield a tree representation of
the program (as a Java or C++ object). Of course a grammar e.g. in
jflex/jbison that will yield the same thing is fine too. We have been
able to find some grammars and parsers, of unknown reliability, that
don't yield a syntax tree; we want to avoid starting with a flaky
parser and/or adding the syntax...

Hi all,
Can anyone recommend a good and *easy to use* lexer and parser generator?
Preferably one that was written specifically for VC++ and not mangled
through 20 different platforms. I've had it up to here (funny hand gesture)
with trying to compile the bullet-riddled code that GNU Flex and Bison keep
spitting out for even the simplest of grammars (really funny hand gesture).

In Linq, you can apparently get a meaningful body from and

also includes a parser? It just seemed it might be a handy way to
write a safe but easy implementation (i.e. no codedom) for an
IBindingListView.Filter (by compiling to a Predicate<T>).
Anybody know if this is possible at all?
