Re: How to get the namespace for an unqualified symbol?
Assuming the symbol is bound to a Var, you can do this: (name (ns-name (:ns (meta (resolve 'x) -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: How to get the namespace for an unqualified symbol?
Yikes! Try ((juxt (comp ns-name :ns) :name) (meta (resolve 'inc))) - name information is stored on the var's meta in a clojure-friendly way - no need to use undocumented behavior on the java internals.

How to get the namespace for an unqualified symbol?
I was looking at combining the namespace and resolve functions: user=> (def x 5) #'user/x user=> (resolve 'x) #'user/x user=> (namespace 'user/x) "user" user=> (namespace 'x) nil user=> (namespace (resolve 'x)) ClassCastException clojure.lang.Var cannot be cast to clojure.lang.Named clojure.core/namespace (core.clj:1497) In the final expression I was expecting to get the value "user". Having read the doc's I understand that the return type from resolve is not compatible with namespace: namespace: Returns the namespace String of a symbol or keyword, or nil if not present. resolve: Returns the var or Class to which a symbol will be resolved in the current namespace else nil. Question: given a symbol 'x' how can I determine the 'fully qualified' symbol (i.e. 'user/x')? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
