Instance Method Details

#cmd ⇒ Object

Trade in this Ruby instance for a JRuby instance, loading in a starter script and passing it some arguments. Unless you set JRUBY: false in ~/.jruby_art/config.yml, an installed version of jruby is used instead of our vendored one. Note the use of jruby-complete might make using other gems in your sketches hard (but not impossible).…
