在控制台中动态更改字体 [英] Change Font dynamically in console

问题描述

是否有适当的插件或类可以在常用输出控制台中更改字体大小，字体类型和装饰？

Is there a proper plugin or a class to change font size, font type and decoration within a common output console?

您可以通过进入偏好设置更改终端的字体但这不是我在这里寻找。我希望能够在代码内动态更改字体。

You can change terminal's font by going into preferences but that is not what I'm looking for here. I want to be able to change font dynamically from within code.

在Ruby或一些终端命令中有任何东西（我使用Mac OS X）。 p>

Is there anything in Ruby or some terminal commands to do so (I use Mac OS X).

推荐答案

ANSI终端中使用的字体/字体大小是实现特定的，ANSI颜色/样式代码是提供装饰的唯一方法。我发现添加颜色和风格到控制台输出的最简单的方法是使用 colorize gem。

The font/font size used in ANSI terminals are implementation specific, and ANSI color/style codes are the only way to provide decoration. Simplest way I've found to add color and style to console output is use the colorize gem.

gem install colorize

示例：

puts "This is blue".colorize( :blue )
puts "This is light blue".colorize( :light_blue )
puts "This is also blue".colorize( :color => :blue )
puts "This is red on blue and underline".colorize( :red ).on_blue.underline
puts "This is blue text on red".blue.on_red.blink

这是 colorize README 。

或者如果你想获得fancier并做一些UI元素，你可以使用 rbcurse gem：

Or if you'd like to get fancier and do some UI elements, you can use the rbcurse gem:

gem install rbcurse
