Hi,
I am new to antlr (antlr3) and struggling with lexing common prefixes.
My simple grammar:
grammar simple;
R : 'R';
E : 'e';
D : '1';
RESULT : 'Result';
expr : ( RESULT | R E D ) EOF;
On input 'Result' I expect token RESULT, and on input Re1 I expect tokens R
E D but input 'Re1' only throws NoViableAltException.
I searched for info 'antlr common prefixes' on the web and tried increasing
k, lookahead predicates ..., things like
RESULT options{filter=true;} : 'Result';
, but to no avail. I would be very much obliged if anyone could give me a
hint.
