clojure.core/refer¶
refers to all public vars of ns, subject to filters. filters can include at most one each of:
:exclude list-of-symbols :only list-of-symbols :rename map-of-fromsymbol-tosymbol
For each public interned var in the namespace named by the symbol, adds a mapping from the name of the var to the var to the current namespace. Throws an exception if name is already mapped to something else in the current namespace. Filters can be used to select a subset, via inclusion or exclusion, or to provide a mapping to a symbol different from the var's name, in order to prevent clashes. Use :use in the ns macro in preference to calling this directly.
Examples¶
Note by KingMob¶
Warning: the referral of a var isn't transitive.
refer only works with a var's original namespace.
If you refer A/foo from B, you can't then refer B/foo from C.
foo it will appear in B's ns-map, but not ns-publics or ns-interns, unintuitively.
