如何使用 Ruby 为终端的文本输出着色? [英] How can I use Ruby to colorize the text output to a terminal?

问题描述

使用 Ruby，如何为终端中的输出执行背景和前景文本着色?

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

我记得，在为 Pascal 编程时，我们都习惯于编写自己的 textcolor(...) 程序，以使我们的小型教育程序看起来更漂亮和更具表现力.

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 中编写等效的代码?核心库中是否有任何内置支持适用于此?如果没有，添加它的惯用方法是什么?

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?
