Hello!
I'm new at ANTLR, and I'm using it to generate code for C# (.NET v3.5).
My grammar is:
tokens {
MODULE;
SPECIFICATION;
}
compilation : specification EOF! ;
specification : ( definition )* -> ^( SPECIFICATION definition* ) ;
definition : module ';' ;
module : 'module' ID '{' specification '}' -> ^(MODULE ID specification) ;
ID : ('a'..'z'|'A'..'Z'|'_') ('a'..'z'|'A'..'Z'|'0'..'9'|'_')* ;
and I have this simple input for test:
module etal { };
And I got
Antlr.Runtime.Tree.RewriteEmptyStreamException{"token ID"},
which is odd, because ID should be 'etal'.
I changed the rule module using operators and got
NullReferenceException, for the same reason.
I am new at this, so I'm not sure how to handle. Is this a bug from
the DLLs that I should report or I am doing something wrong? Because I
tried the same grammar using ANTLRWorks and changing the language to
Java, and it worked like a charm, with no errors.
I don't know if this was already discussed, thought I searched for
this at the most recent Interest Archives. If it was, sorry.
Thank you all very much for any help.
