[antlr-interest] how to eliminate non-determinism warnings upon keywords and literals?

[Fan Yang]

Hi,

There are some non-determinism warnings for the following grammar

////// snippit1
class TestLexer extends Lexer;
...
TOKEN_IFDEF	:	"ifdef" { semantic actions }
	;

ID	:	('a'..'z')+
	;
//////

I know I can use token {...} section to eliminate those warnings, but 
I can't add semantic actions in the tokens section, which is 
important for me. 

My question is how to get rid of those warnings by using the same way 
as snippit1 indicated.


I really appreciate your help,

fan 

////// snippit2
// One solution but I can't use semantics action
class TestLexer extends Lexer;
...
tokens {
        BEGIN="begin";
}

ID	:	('a'..'z')+
	;
