[antlr-interest] always missing some charactor when using ANTLR to generate lexer and parser

[lin cyrix]

I encountered a problem when using ANTLR to generate
lexer or parser java files. for example :

1, missing '('
throw new NoViableAltExceptionLT(1), getFilename());
should be :
throw new NoViableAltException(LT(1), getFilename());

2, missing 's' of 'result'
reult.value = new Double(Math.atan(
((Double)a.value).doubleValue() ));
should be :
result.value = new Double(Math.atan(
((Double)a.value).doubleValue() ));

3, missing 't' of '_ttype'
_token = makeToken(_type);
should be :
_token = makeToken(_ttype);

Why? Each time when I use ANTLR to compile calc.g,
there are always several this kind of missings. Can
anyone tell me the probable reason ?

Thanks in advance
