I normally call
(keys (ns-publics 'foo))
to list Vars exported by the namespace foo
; e.g. for clojure.contrib.monads
this returns
(defmonad censor m-when-not m+write+m maybe-m maybe-t ...)
(the ...
stands for quite a lot more).
More generally, there’s a bunch of functions whose names start in ns-
which list Vars by namespace, with certain additional criteria attached:
-
ns-map
— the most general function of all, returns a map keyed by symbols (non-namespace-qualified symbols actually), where the value corresponding to each symbol is the Var or class that symbol resolves to in the given namespace. -
ns-interns
— likens-map
, but includes only the Vars interned in the given namespace (as opposed to Vars from other namespaces which are accessible from the given namespace due to ause
orrefer
call or the implicit referral of Vars fromclojure.core
. -
ns-publics
— likens-interns
, but includes only the non-private Vars. -
ns-imports
— likens-map
, but includes only the entries whose values correspond to Java classes.
There’s also ns-aliases
which lists symbols which can be used as shorthand aliases when referring to Vars from other namespaces; e.g. if you call (require '[clojure.contrib.math :as math])
, ns-aliases
will include an entry with the key of math
(the symbol), whose value will be the actual namespace clojure.contrib.math
. These mapping are not included in the map returned by ns-map
.
