Hello,
I have the following grammar that parses the string "x2" successfully
as two different tokens:
----
%tokens%
OPERATOR = "x"
NUMBER = <<[0-9]*>>
WHITESPACE = <<[ \t\n\r]+>> %ignore%
%productions%
Value = OPERATOR NUMBER ;
---
When I add the token definition IDENTIFIER = <<[a-zA-Z][a-zA-Z0-9-_]*>>
,
the string "x2" results in a parse error, since it is parsed as a single
IDENTIFIER token. Is there something that I can do to prevent this?
Best regards,
Wieger
