Hi,
I am having a nondeterminism waring on my Lexer.
Here is what I have in my Lexer
protected SPECIAL : "special::" ;
protected VARIABLE : ('a'..'z'|'A'..'Z'|'_') ('a'..'z'|'A'..'Z'|'_'|'0'..'9')* ;
SPECIAL_FLAG : SPECIAL! FLAG ; // Match SPECIAL followed by some FLAG
BEGIN_FUNCTION : ( VARIABLE LPAREN! ); // Match the beginning of any function
On compiling the grammar
Warning: lexical nondeterminism between rules SPECIAL_FLAG and BEGIN_FUNCTION upon k==1:'s' k==2:'p
I am not sure how to get rid of this problem and would appreicate if someone can help me match both these lexer rules.
Thanks
Sriram
