Clojure中read-string和load-string的区别 [英] Difference between read-string and load-string in Clojure

问题描述

我有一些代码工作后，用load-string替换read-string。这是好的代码工作，但我想知道为什么。两个clojure函数之间的区别是什么？

I have some code which works after replacing read-string with load-string. It is good that the code works, but I would like to know why. What is the difference between the two clojure functions?

推荐答案

使用load-string顺序读取和评估
string

Use load-string to sequentially read and evaluate the set of forms contained in the string

使用read-string从字符串s中读取一个对象

Use read-string to read one object from the string s

引自 Clojure API ）

string会将你的字符串作为一个Clojure表达式，read-string接受这个字符串并返回它作为找到的数据结构，在这种情况下可能是一个表达式。

Load-string will evaluate your string as a Clojure expression, and read-string takes the string and returns it as the found data structure, in which case might be an expression.

Protip： load-string（+ 1 2）和 eval（read-string（+ 1 2））你的结果相同，这是3}

{Protip: load-string(+ 1 2) and eval(read-string(+ 1 2)) will give you the same result, which is 3}
