I suppose you could use a global binding, and do (binding [*name* "whatever"] (my-view)), but I'm not sure that's any better than just passing in the parameter. eg. (def *name*) (defn my-view [] (str "hello " *name*)) (binding [*name* "world"] Another option would be to pass the view functions a map of keywords to replacements so that you can have a single data structure that's easily applied to multiple views. -- Jarkko --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
