Hi,
I'm highly interested in ruta, and its potential applications in industrial
applications. Right know I'm trying to create a simple toy condition
extension that is simply a case insensitive INLIST condition. It is
completely based on the InListCondition class, I also declared an
implementation of the IRutaConditionExtension interface.
With primitve types everything seems to work great, except when the
condition is used with a variable :
STRINGLIST MonthsList = {"january", ...};
DECLARE Month;
ANY{INSENSITIVEINLIST(MonthsList) -> MARK(Month)};
I get a class cast exception when the condition is being created, because
MonthsList is a SimpleTypeExpression and I'm expecting a StringListExpression.
Am I doing something wrong ? I suppose there is a way to resolve the
variable to the actual list, but I missed it somehow.
It may not help you to get your toy extension working, but for small
lists I like to use regular expressions where case insensitiveness is free:
W{REGEXP("(?i)january|february|march|...|december") -> MARK(Month)}
Regards,
Alexandre
