Ok, folks, time to come up with a better name for lexer rules that are
not real tokens (they are only rules called by other rules). Currently
it's "protected", which is hideous:
FLOAT : (DIGIT)+ '.' DIGIT | (DIGIT)+ ;
protected
DIGIT : '0'..'9' ;
Ick. So, should it be an option or keyword? What would the name be?
I can't even describe it exactly even in two words. :(
"non token"? "method"? "macro"? "internal"?
Help!
I need to implement this now in the 3.0 system.
