Hi everybody,
I have identified which piece of code returns « False » (and sometimes « True
») and make ANTLRWorks throw a "java.lang.NumberFormatException".
It is the result of 2 semantic predicates embedded in the same rule :
// beginning of rule (...)
| {input.LA(1) == MY_TOKEN}? // (...) First production
| {input.LA(1) != MY_TOKEN}? // (...) Second production
// (...) end of rule
;
I am used to work with ANTLR 2.7.7, so this syntax may be wrong under ANTLR
3.1.3.
Could anybody help me please ?

Objet : [antlr-interest] Exception while debugging C# 2.0 with ANTLRWorks1.2.3
Hi,
I am currently trying to debug a SQL grammar generated by ANTLR 3.1.3 with
ANTLRWorks 1.2.3.
I have upgraded ANTLRWorks as explained in Readme.txt to make it compliant with
v 3.1.3.
I generate my lexer and parser files with "-debug" option. Then I launch
parsing under Visual Studio 2008, and finally I do a "Debug Remote" under
ANTLRWorks. All seems to work first. I was able to debug my grammar with
several .sql files. But sometimes, I get a :
java.lang.NumberFormatException: For input string: "False"
that is not handled by ANTLRWorks. Then the application freezes and I have to
stop debugging.
Do you have an idea to solve that issue ?
Cheers,
