在Clojure中，如何定义一个以字符串命名的变量? [英] In Clojure, how to define a variable named by a string?

问题描述

给定变量名称列表，我想将这些变量设置为表达式.

Given a list of names for variables, I want to set those variables to an expression.

我试过了:

(doall (for [x ["a" "b" "c"]] (def (symbol x) 666)))

...但这会产生错误

java.lang.Exception: def 的第一个参数必须是 Symbol

java.lang.Exception: First argument to def must be a Symbol

谁能告诉我实现此目的的正确方法吗?

Can anyone show me the right way to accomplish this, please?

推荐答案

Clojure 的实习生"功能就是为了这个目的:

Clojure's "intern" function is for this purpose:

(doseq [x ["a" "b" "c"]]
  (intern *ns* (symbol x) 666))
