在我的应用程序中,我需要将 clojure 关键字,例如: var _ name 转换为字符串“ var _ name”。有什么办法吗?
user=> (doc name) ------------------------- clojure.core/name ([x]) Returns the name String of a string, symbol or keyword. nil user=> (name :var_name) "var_name"
Note that kotarak's answer won't return the namespace part of keyword, just the name part - so :
(name :foo/bar) >"bar"
Using his other comment gives what you asked for :
(subs (str :foo/bar) 1) >"foo/bar"
Actually, it's just as easy to get the namespace portion of a keyword:
(name :foo/bar) => "bar" (namespace :foo/bar) => "foo"
Note that namespaces with multiple segments are separated with a '.', not a '/'
(namespace :foo/bar/baz) => throws exception: Invalid token: :foo/bar/baz (namespace :foo.bar/baz) => "foo.bar"
And this also works with namespace qualified keywords:
;; assuming in the namespace foo.bar (namespace ::baz) => "foo.bar" (name ::baz) => "baz"
This will also give you a string from a keyword:
(str (name :baz)) -> "baz" (str (name ::baz)) -> "baz"
It's not a tedious task to convert any data type into a string, Here is an example by using str.
(defn ConvertVectorToString [] (let [vector [1 2 3 4]] (def toString (str vector))) (println toString) (println (type toString) (let [KeyWordExample (keyword 10)] (def ConvertKeywordToString (str KeyWordExample))) (println ConvertKeywordToString) (println (type ConvertKeywordToString)) (ConvertVectorToString) ;;Calling ConvertVectorToString Function Output will be: 1234 java.lang.string 10 java.lang.string
