Hello,
I tried the following: I fixed the token types with *TokenTypes.txt
in a TreeParser. Everything just works fine except when I tried to
use a TOKEN RANGE (ie. (TOKEN_1 .. TOKEN_2)). There is no complaint
from ANTLR 2.7.1, but its generated code can't be compiled by javac.
There
is a line like:
match(TOKEN_1, TOKEN_2);
there match(..) is not a method of TreeParser.
This are my questions:
1. Is it possible to have token ranges at all or are ranges limited
to lexers?
2. Is there a way to define the method match(..) so that the token
range just works fine?
3. Is it the same for not matches like in (~TOKEN_1).
By the way, apart from this problem, I think ANTLR is a great tool.
Cheers,
Thomas
