I think the problem is the EOF token
programa: (sentencia ';')+ EOF -> ^(PROGRAMA sentencia+); //this's not ok
programa: (sentencia ';')+ -> ^(PROGRAMA sentencia+); //this's ok

No, this is the error detected by java compiler.
I think "list_-1" is a bug in the java code generated by antlr, or an error
in my grammar ;-)

Is "*list_-1*" a valid variable name?

I don't know if this is a bug or a error in my grammar. This occur in a
debug session of antlrworks with these version tools ANTLRWorks 1.0ea9
ANTLR 3.0ea10 StringTemplate 2.3b7 XJLibrary 1.2.6 Java 1.5.0_02 (Sun
Microsystems Inc.)
With this grammar
grammar Transformer;
options {output=AST;}
tokens {PROGRAMA;}
programa: (sentencia ';')+ EOF -> ^(PROGRAMA sentencia+);
sentencia: setDir;
setDir : 'set' 'dir' LITERAL ;
LITERAL : '"'(options {greedy=false;}:.)* '"';
It generate this error
[11:05:51] C:\Documents and Settings\JVR3651A\My
Documents\java\Transformer\Transformer.java:65: ';' expected
[11:05:51] List list_-1=new ArrayList();
[11:05:51] ^
because the java code generated is wrong
[...]
List list_sentencia=new ArrayList();
List *list_-1*=new ArrayList();
List list_6=new ArrayList();
Object char_literal2_tree=null;
Object EOF3_tree=null;
[...]
It's a bug?
thank's in advance.
