to do so at the grammar level.
Thanks.

So you went into preferences and set the port to 49100?
Yes, localhost implies the local computer, which doesn't usually have
ports blocked.
I'm not sure what OS you're on, but what port(s) does netstat show
ANTLRWorks is using?
There's a number of other fixes related
to custom tree adaptors, including making the generated JUnit code
contain the necessary imports and passing the tree adaptor to the
CommonTreeNodeStream.
I'm sure upgrading to the latest gunit will fix the problem. Thanks

save me some of that time.

My first thought is that I messed up the class name, but that's not the case
because I verified the name and it fails in exactly the same way with a fully
qualified class name. Additionally, I tried ANTLR's CommonTreeAdaptor and I
still receive the same error. I'm using Sun
tree value?
That thought crossed my mind, but it seemed like it should be unnecessary. I
gather then that it's not possible to set it directly?

I think that would be a nice syntax for ANTLR to support.
I would guess that you could generally accomplish the same thing by
placing the "opposite" syntactic predicate on your other
alternative(s) in your production. In other words:
(a b)=> alternative_1
| alternative_
> expr : cat
> | cat WHEN dog
> | dog
You could do:
expr: cat (WHEN dog)? | dog;
You should also be able to use a syntactic predicate:
expr: (cat WHEN)=> cat WHEN dog
| cat
| dog;

Can anybody recommend some good links to best practices for AST building?
In the past, I've manually built heterogeneous trees via the actions
associated with various productions. This works, but I'm hoping to
find something better.
I've been looking at the ANTLR examples and how they generate

I have a grammar that contains the following production:
objectMember : functionExpression | ID;
The unit tests for the above production, however, sometimes passed and
sometimes failed. After some investigation, I found that the reason
for the failure was that EOF wasn't in the expected follow

Everything is an object in the language I'm creating. Thus, I allow:
"string".someFunction(), and
1234.equals(1234)
I'm using the latter as a testcase. It's being parsed as follows:
1234. =>
1. Take object production
2. Take alt2
3. Consume 1234
4. See '.'
4. Try DECIMAL p

I'm not sure exactly what you need. Do you need:
