Hi,
I keep getting following errors:
warning(138): Query.g:0:0: grammar Query: no start rule (no rule can obviously
be followed by EOF)
warning(200): Query.g:27:40: Decision can match input such as "OR" using
multiple alternatives: 1, 2
As a result, alternative(s) 2 were disabled for that input
warning(200): Query.g:31:39: Decision can match input such as "AND" using
multiple alternatives: 1, 2
As a result, alternative(s) 2 were disabled for that input
warning(200): Query.g:39:7: Decision can match input such as "WORD" using
multiple alternatives: 1, 2
As a result, alternative(s) 2 were disabled for that input
I kind of understand why because if the input is "OR" the parser will just
freak out. What I want do is a simple boolean query input validator
(1) valid input:
a OR b
c AND d
a OR b AND d
(2) invalid input:
a AND
AND b (This is not working)
What's wrong with the grammer? I really cannot figure it out.
Thanks !
