how to make color for a string in Ruby

Question

How to make color for a string in Ruby? For example, define a method make_color,

def make_color(str, :red) end

Then the output will return the String str with red color.

I wonder whether there is a lib in ruby can help me do that?

ps: I prefer not using gem package.

@Linuxios, Yes, I will output the string in a UNIX/LINUX box terminal. — dj199008

Take a look at colorize gem

Install the gem and you can use colorize method to specify the color you want

require 'colorize' puts "This is blue".colorize( :blue )

Or you can simply use the codes as you would in bash

for eg:

def make_color(str, color) colors = {:red => 31, :green => 32, :blue => 34} puts "\e[#{colors[color]}m #{str}\e[0m" end
