红宝石的终端颜色？

Question

是否有一个ruby模块用于在linux终端中着色字符串？

Answer 1

我更喜欢Rainbow gem,因为如果安装了win32console gem,它也支持Windows.

你可以像这样使用它:

puts "some " + "red".color(:red) + " and " + "blue on yellow".color(:blue).background(:yellow)

你所要做的就是从一开始就"\e[##m"结束"\e[0m"

只需将##替换为颜色编号即可.例如:

31:Red 32:Green 33:Yellow 34:Blue 35:Magenta 36:Teal 37:Grey

1:Bold (Can be used with any color)

这是一个显示所有终端颜色的ruby脚本.下载或运行下面的代码.

def color(index)
  normal = "\e[#{index}m#{index}\e[0m"
  bold = "\e[#{index}m\e[1m#{index}\e[0m"
  "#{normal}  #{bold}  " 
end

8.times do|index| 
  line = color(index + 1)
  line += color(index + 30)
  line += color(index + 90)
  line += color(index + 40)
  line += color(index + 100)
  puts line
end

使用String类方法,如:

class String
def black;          "\033[30m#{self}\033[0m" end
def red;            "\033[31m#{self}\033[0m" end
def green;          "\033[32m#{self}\033[0m" end
def brown;          "\033[33m#{self}\033[0m" end
def blue;           "\033[34m#{self}\033[0m" end
def magenta;        "\033[35m#{self}\033[0m" end
def cyan;           "\033[36m#{self}\033[0m" end
def gray;           "\033[37m#{self}\033[0m" end
end

和用法:

puts "This prints green".green
puts "This prints red".red
