CodeRay stylesheet

Question

require 'coderay'
puts CodeRay.scan('puts "Hello, world!"', :ruby).page

This code will print full HTML page with CSS(classes).

I may print only colored code using CodeRay.scan('puts "Hello, world!"', :ruby).div
How can I print only CSS part?

There is stylesheet method in CodeRay::Encoders::HTML::Output, but how can I call it?

Answer 1

The coderay command installed along with the CodeRay gem can print out a stylesheet for you.

$ coderay stylesheet > coderay.css

Or you could do something with it in code maybe.

require 'coderay'

style = CodeRay::Encoders[:html]::CSS.new(:default).stylesheet
puts style
