在clojure中从“a”到“z”生成字符序列 [英] Generate character sequence from 'a' to 'z' in clojure

问题描述

我想从a到z生成字符序列。
在scala中，我可以非常简单地生成字符序列：

I want to generate character sequence from 'a' to 'z'. In scala, I can generate character sequence very simply:

('a' to 'z')

但在clojure中，我最终得到以下代码：

But in clojure, I end up with the following code:

(->> (range (int \a) (inc (int \z))) (map char))

或

(map char (range (int \a) (inc (int \z))))

我详细。有更好的方法吗？

It seems to me verbose. Are there any better ways to do it?

推荐答案

如果代码看起来冗长，它通常只是一个标志，输出到一个单独的函数。作为一个奖励，你有机会给这个函数一个有意义的名字。

If code looks "verbose" it's often just a sign that you should factor it out into a separate function. As a bonus you get the chance to give the function a meaningful name.

只要这样做，你的代码将更容易阅读：

Just do something like this and your code will be much more readable:

(defn char-range [start end]
  (map char (range (int start) (inc (int end)))))

(char-range \a \f)
=> (\a \b \c \d \e \f)
