ruby version in code code example

Example 1: how to check ruby version

// Command line:
$ ruby -v

// Within irb type "RUBY_VERSION"
# => "2.4.1"

// If using RVM:
$ rvm current
# => ruby-2.4.1

Example 2: ruby version from script

There is a RUBY_PATCHLEVEL constant as well. So you can get your version string as

p "#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"
