It seems that the Lexer rules are not validated if they exist or not. I have simplified the grammar to show the issue: If you use a parser rule that doesn't exist, the VS2010 plug-in complains but if it's a Lexer rule, not only it doesn't complain, but it generated the Lexer+Parser and it compiles with no errors.
In the following sample LexerRule doesn't exist. grammar TestGrammar; options { language=CSharp3; TokenLabelType=CommonToken; output=AST; ASTLabelType=CommonTree; } public compileUnit: parserRule EOF; parserRule: LexerRule; LEXERRULE2: 'VALUE'; -- You received this message because you are subscribed to the Google Groups "il-antlr-interest" group.
