I'm using antlr-3.2 with Java and have an grammar with options
{output=template}.
Any test for the rule without template's closure fails because of
NullPointerException in org.antlr.gunit.gUnitExecutor:
....
else if (method.getName().equals("getTemplate"))
{
final Method returnName =
_return.getMethod("getTemplate");
final StringTemplate st = (StringTemplate)
returnName.invoke(ruleReturn);
stString = st.toString(); //here comes
NullPointerException
//must be stString = (st!=null ? st.toString() :
null);
}
....
If a grammar has a rewritable=true option all tests have got a
ClassCastException when Parser is trying to rewrite the input because of the
next line in org.antlr.gunit.gUnitExecutor:
protected gUnitTestResult runParser(final String parserName, final String
lexerName, final String testRuleName,
final gUnitTestInput testInput) throws Exception
{
....
final CommonTokenStream tokens = new CommonTokenStream ((Lexer)
lexObj); //Hier must be a TokenRewriteStream!
.....
Thanks
