Hi all,
I'm new to antlr and try fix follow problem.
I need a rule that match characters, depend on token, follow the 'main' token.
OP_AND : ('A'|'a') ('N'|'n') ('D'|'d');
TEXT : ('a'..'z'|'A'..'Z')+;
PLUS : '+';
The rule OP_AND should match only, if after the input 'and' isn't a '+', so
'and' --> should match rule OP_AND
'and+' --> should match 2 rules: the rule TEXT 'and' and rule PLUS '+'
Thanks in advance
Andrei
