Hi,
I can't get ANTLR 3.1b1 to generate ASTs using C#. Am I doing something wrong or is the beta not generating valid C# yet?
Here is the very simplistic grammar I use. Parsing "1+1" will break with a RewriteEmptyStreamExceptions
grammar Simple;
options
{
output=AST;
ASTLabelType=CommonTree;
language=CSharp2;
}
expr : INT '+' INT -> ^('+' INT+);
INT : ('0'..'9')+;
WS : (' '|'\t'|'\u000C'|'\r'|'\n') {Skip();};
Any ideas?
Thanks
Andre
