I'm getting a non-LL(*) decision error when trying to generate code
for my grammar, which is at http://rebertia.com/Iguana.g (it's a bit
long, otherwise I'd post it).
I've tried looking at the flowcharts in ANTLRWorks to figure out what
the problem is, but I can't make heads or tails of what the

Hi,
Is there any reason the many *_return classes generated when a grammar
uses the "returns [ ... ]" construct (under Java) cannot be
declared "private" (or, at least, "protected")?
This would have the salutary effect of excluding them from the external
JavaDoc HTML typically generated from
Hi. I had not thought of that. yes that is a problem, but you need to
access the return structures to pull results from the start symbol
like the tree.

Gavin,
Yeah, I goofed the line numbers up. Here are the files again. My
question is whether the syntax is correct. I can't see anything
wrong. Thanks for any help.
grammar Foo;
options {
output=AST;
}
tokens {
FOO = 'foo';
BAR = 'bar';
ZAP;
}

This is due to the way Lexer and Parser separation works - the lexer
produces tokens, which the parser consumes and
Hi,
for the grammar below, when it parses the input
REMOVE NONE
there is a MismatchedSetException
When I change the NONE in r1 to NON the phrase is parsed.
Seems that the NONE is in a list of known tokens and cannot be entered
for ID, isn't it?
It surprises me, that using a TOKEN breaks a ru

Any idea?

Seem it needs to be
or
<(typeMap.(a.type))(a)>
But how do I add a prefix?

Found the map iteration explained here

For iteration of lists/trees - recursively call the templates?

Hey there,
Hope this is the right mailing list for stringtemplate questions.
(Wasn't obvious from the site)
I have some trouble figuring out how to output tree like structures
and maps with stringtemplate. Could not find an example for it.
Let's say I have
Map map = new HashMap
Hi, Jim,
Sorry to bother you again.
As I mentioned before, I use the same lexer and parser object for parsing
different SQL statements.
When using ANTLR3.0.1, everything works fine, but when upgrade to ANTLR3.1,
I found that it is necessary to save the
ctx->pParser->rec->state->tokenNames before c
Yes, this is the easiest way to make it work.
It is not I who designed the architecture. But I think the reason may be the
performance, the parser object contains over 1000 fields needed to be set,
it may be much faster to reuse it by resetting some fields of it.

Is there some particular reason why you don't want to construct a
new instance?
