如何使用Ruby对输出到终端的文本进行着色? [英] How can I use Ruby to colorize the text output to a terminal?

问题描述

使用Ruby，如何在终端中对输出的背景和前景文本进行着色?

Using Ruby, how can I perform background and foreground text colorization for output in the terminal?

我记得，在对Pascal进行编程时，我们都曾经编写过自己的 textcolor(…)过程，以使我们的小型教育程序看起来更美观，更具表现力.

I remember, when programming Pascal we all used to write our own textcolor(…) procedures to make our small educational programs look more pretty and presentational.

我将如何在Ruby中编写与之等效的代码?核心库中是否有任何内置支持可用于此目的?如果没有，添加它的惯用方式是什么?

How would I go about coding an equivalent of that in Ruby? Is there any built-in support in the core library that lends itself to this? If not, what would be an idiomatic way to add it?
