Pass parameters with using FLEXFIX #201

How does reflex use the FLEXFIX argument to pass arguments to yylex like flex？

genivia-inc commented 5 months ago

Can you point to the Flex documentation that defines this FLEXFIX argument? It's not mentioned in the official Flex documentation.

Arguments passed to yylex() depend on options. The argument list can also be extended with whatever parameters you want using %option params="PARAMS" see manual and also YY_DECL alternatives

I solved the problem of passing parameter values by using %option params="PARAMS", thanks.
