Potemkin’s import-vars is the most reliable way I know to make a namespace that gathers vars from several namespaces and presents them as a unified API. This namespace builds on it. See the tests and commons.clojure.core for two examples of creating a “favorite functions” namespace that can be included everywhere with (for example) (ns my.ns (:use my.clojure.core)).

import-all-vars

macro

(import-all-vars & ns-syms)

Import all public vars from the namespaces, using Potemkin’s import-vars.

   (import-all-vars clojure.set) ; note namespace is unquoted.

import-prefixed-vars

macro

(import-prefixed-vars ns-sym prefix)

Import all public vars from the namespace, using Potemkin’s import-vars. Within the current namespace, the imported vars are prefixed by prefix, a symbol.

 (import-prefixed-vars clojure.string str-) ; note lack of quotes
 (str-trim "  f ") => "f"
view source

import-vars

macro

(import-vars & namespace-and-var-descriptions)

Import named vars from the named namespaces and make them (1) public in this namespace and (2) available for refer by namespaces that require this one. See Potemkin for more.

 (import-vars [clojure.math.combinatorics
                  count-permutations permutations]
              [clojure.data.json
                  write-str])
