There are plenty of coloring libraries: colored, term-ansicolor. But is there any which can do this:
puts "#{'hello'.red} world!".bold And world! should be bold.
To make it clear, I want to get this:
"\e[1m\e[31mhello\e[0m\e[1m world!\e[0m" or better even this (just shorter):
"\e[1;31mhello\e[0;1m world!\e[0m" instead of this:
"\e[1m\e[31mhello\e[0m world!\e[0m" As there is none, I wrote my own, with blackjack and hookers smart one — smart_colored
gem install smart_colored and run
require 'smart_colored/extend' # without extend you'll need to use 'string'.colored.red puts "#{'hello'.red} world!".bold The lib is called Highline It has a color method: say("This should be <%= color('bold', BOLD) %>!") Which can be easily used to implement String#bold.
HighLine.new.color("#{HighLine.new.color('hello', HighLine::RED)} world!", HighLine::BOLD)): ` world!` is not boldIn case you are using highline I made a gem that extends colors and provides helpers such as:
say_bold 'this is bold text' 
<strong><span style="color:red">hello</span> world!</strong>? I want same thing in bash and I was just trying to know if there is already such library and if not I'll write my own."red #{"green".green} red".red?helloto be red (and bold as it is part of string). For your example html equivalent is<span style="color:red">red <span style="color:green">green</span> red</span>.
