;; the name of the keyword is without the ':' ;; "str" will retain the ':'. (name :x) ;;=> "x" (name "x") ;;=> "x" ;; returns the symbol name as a string without the namespace. (name 'x) ;;=> "x" (name 'user/x) ;;=> "x" ;; throws an error for invalid types, no nil punning (name nil) ;;=> Error: Doesn't support name: (name 2) ;;=> Error: Doesn't support name: 2

;; Note that for namespaced keywords, `name` only returns the name part. (name :my-ns/my-name) ;;=> "my-name" (name :ns/deep/key) ;;=> "deep/key" ;; For more info see: `keyword` and `keyword?`... (name :'//-,) ;;=> "/-" (name :/) ;;=> "/" (name ://) ;;=> RuntimeException Invalid token: :// clojure.lang.Util.runtimeException (Util.java:221) ;;=> RuntimeException Unmatched delimiter: ) clojure.lang.Util.runtimeException (Util.java:221) (name :///) ;;=> "//" (namespace :///) ;;=> "" ;; If you want the namespace part, you can use (namespace): (namespace :my-ns/my-key) ;;=> "my-ns" ;; Using (str) will give you both parts, but also includes the leading colon. (str :my-ns/my-key) ;;=> ":my-ns/my-key"

;; To get full key (defn keyname [key] (str (namespace key) "/" (name key))) (keyname :ns/key) => "ns/key" (keyname :ns/deep/key) => "ns/deep/key" ;; Just for fun (string/replace :key/val #"^:" "") => "key/val"

;; `name` (and `namespace`) "knows" how a keyword was built: (name (keyword "a/b" "c")) ;;=> "c" (name (keyword "a" "b/c")) ;;=> "b/c"

;; To get the fully qualified name of the keyword, we can use symbol. (str (symbol :a/b)) ;;=> "a/b"
