I'm trying to create Python parser/interpreter using ANTLR.
Reading grammar from language refference I found:
or_expr::= xor_expr | or_expr "|" xor_expr
For me it looks like infinite recursion. And so it says ANTLR. Maybe I
don't understand EBNF notation. For me it should look like this.
or_expr::= xor_expr | xor_expr "|" xor_expr
and in...

I am currently in India and have treated myself to the Indian reprint
of O'Reilly's "C++ In A Nutshell". (Books in India come in at 1/3 to
1/2 of the price in Britain.)
I thought that I would have a look at what Chapter 12 on grammar says
about Declarations and Definitions. Now I'm more baffled than when I
started.
Here's the problem.

Hello,
I have a question about the correctness of the language grammar for the C#
2.0 specification. I am working with the grammar specified in the June 2005
ECMA-334 standard.
Basically, a using-namespace-directive is defined as follows:
using-namespace-directive:
using namespace-name ;

I am trying to come up with a grammar that describes the following:
record = f1,f2,...,fn END_RECORD
All the f(i) has to be in that order.
Any f(i) can be absent (e.g. f1,,f3,f4,,f6 END_RECORD)
Number of f(i)'s can vary. For example, the followings are allowed:
f1,f2 END_RECORD
f1,f2,,f4,,f6 END_RECORD
Any suggestions?

Hi all,
I'm trying to work out a parser for function declarations but it turns
out that it is harder than I initially thought.
I'm looking at 3rd Ed of Stroustrup, page 808.
I'm trying to parse something like:
int foo(int, int);
const double *xpto(mytype *, mytype &) const;
But I'm not being able to find my way around the grammar.

(Please let me know if there's a better group to post in.)
Some questions:
(1) Is this grammar specification known to be complete and...
