Ruby colorize a section of text - ruby

Question

I am writing a command line script in ruby and I am trying to color a section of lines. Currently, I am using the 'colorize' gem, but from the documentation it only lets you color one line of text at a time
puts "test".colorize(:green)
puts "test".colorize(:green)
puts "test".colorize(:green)
But, that seems a bit redundant to me and I would like to color all the lines of text, but only call 'colorize(:green)' once and not 3 times.
How can this be done in Ruby?

Answer 1

Define a method for this:
def putsg(text)
puts text.colorize(:green)
end
And than call that method:
putsg "test"
putsg "test"
putsg "test"

Answer 2

puts ["test", "test", "test"].join($/).colorize(:green)
or
puts ["test", "test", "test"].map{|s| s.colorize(:green)}

Answer 3

Regarding your statement "...but from the documentation it only lets you color one line of text at a time"
You can colorize different parts of the same line with different colors.
s = "Hello"
ss = "world"
puts "#{s.red} #{"there".white} #{s.blue}"
You can also accomplish your aim like this:
s = "test"
puts "#{s}\n#{s}\n#{s}".green
Or:
s1 = "check"
s2 = "this"
s3 = "out"
puts "#{s1}\n#{s2}\n#{s3}".green

Answer 4

You can also define a method like this:
The input is the color you want as a string and the text you want outputed. This will work in the command prompt.
def colorized_text(color,text)
#Find colors here: https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit
color_code_hash = {
'red' => 196,
'green' => 40,
'yellow' => 226,
'blue' => 27,
}
puts"\e[38;5;#{color_code_hash[color]}m#{text}\e[0m"
end
I found this to be much better than using the colorize gem since that only gives you 8 colors. You can find all the colors on the ansi escape wiki page under the 8 bit section.
