[antlr-interest] ANTLR3 C# InvariantCultureIgnoreCase

[Dr. Kocher, Hartmut]

Hi Fabio,

yes, you could still use this solution. Parsing is done in all lowercase (i.e. in your grammar you specify your keywords in all lowercase ("order"). Your identifiers will be matched as lower case. However, the original case is preserved in the token. Therefore, $Ident.text is still mixed case!

Hope this helps.

Regards
Hartmut

The CaseInsensitiveStringStream work even if I need *caseSensitive* Idents ?

Ident: Letter (Letter|'0'..'9')*;

I mean...
I need that a token like ORDER='order' must match with :
Order, oRder, oRdER ... and so on
But the a word like AnIdentifier must be different than anIdentifier.

In my lenguage keyWords are CaseInsensitive but identifiers are 
CaseSensitive.

Fabio.
