Hallo everyone,
I am new to the list and first of all I would like to thank Terence Parr
and Jean Bovet for their wonderfull software.
I just bought the book 'The Definitive ANTLR Reference' Version
2007-7-29 and copied the example in chapter 3, Expr.g. It works as
written in the text, for example with '3+@' or '(3' that is, the error
is reported is exactly as in the book. But when I enter '(3+4)*5' the
syntax tree in the interpreter shows a NoViableAltException and the
debugger has the right result 35 but states: Line 1:4 no viable
alternative at input ')'. The same happens when I run the Test.java
which I do in Eclipse. From the syntax tree I see that another multExp
is started which find no satisfying value for the atom. How can one stop
the parsing at this point or what is wrong?
Kind regards
Rolf
