I'm not 100% sure, but I think hsplugins can dynamically load compiled *.o files in this way. Correct.
Not sure whether this requires the person running the main program to have GHC installed though. Yes, it does.
Thanks && ciao, Leif
Unlike Java, there's no reflection capabilities. This isn't too bad though; just write your own class definition to allow your main program to query the thing it just loaded and find out what it offers.
class Describable d where available_functions :: d -> [FunctionInfo]
data FunctionInfo = FunctionInfo {name :: String, description :: String, ...}
Unlike general reflection (where you try to guess things from function names and so on), this can be taylored to exactly the kind of plugins you're trying to write.
