Can't dynamically bind non-dynamic var
hi clojure-users, for testing an app that uses quil, i want to mock out some function-calls to the quil-library ... when i do it like this: (ns myapp (:use clojure.test) (:require [quil.core :as q])) (deftest (binding [q/height (fn [] 400)] (is 400 (q/height i get an Exception that says: actual: java.lang.IllegalStateException: Can't dynamically bind non-dynamic var: quil.core/height Any hints, how this an be solved or circumvented ? thanks & have a successful day -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Can't dynamically bind non-dynamic var
I was experimenting with dynamic binding of vars with Clojure 1.3, as described on http://clojure.org/vars and got this error: user=> (def x 1) user=> (binding [x 2] x) IllegalStateException Can't dynamically bind non-dynamic var: clojure.core/x clojure.lang.Var.pushThreadBindings I figured out the solution to this on a blog entry: http://blog.japila.pl/2011/03/cant-dynamically-bind-non-dynamic-var-in-clojure-1-3/ (use ^:dynamic when defining x) Is this new feature documented anywhere in the official documentation? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
