Hello,
I'm new to this mailing list, so hello everyone.
I currently try to create a grammar to parse a textual wiki syntax.
I'm using ANTLR 3.4 and the Java generator.
I've reached a situation where ANTLR creates empty ifs in the generated Java
code and I boiled it down to the following grammar:
grammar failuretest;
start: letter+;
letter: 'A' .. 'B';
The resulting Java code contains the following statements:
...
if ( () ) {
...
if ( ) {
...
As far as I know this is no legal Java. And the grammar looks fine to me, apart
from that the second rule should probably be a lexer rule.
So could this actually be a bug in antlr?
Many thanks in advance,
Patrick Zimmermann
