So I wrote the code attached and added it to my user.clj. It allows you to make the calls like these: user> (sprintf *out* "%s = %-10.4f\n" "pi" Math/PI) pi = 3.1416 nil user> (slprintf System/out java.util.Locale/FRANCE "%s = %-10.4f\n" "pi" Math/PI) pi = 3,1416 nil user> (sprintf *err* "Divided by %s error\n" (if (zero? 0) "zero" "NaN")) Divided by zero error nil I'd like to see the code merged in the core... -- Kei --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
