Plugin for using Ruby code in Grails via JRuby.


grails install-plugin ruby


Ruby Plugin

The Ruby plugin provides easy access to execute Ruby code from any Grails artifact (controllers, taglibs, services etc...)


To install the Ruby plug-in just run the following command from within an existing Grails project:

grails install-plugin ruby


The plugin expects to find Ruby source files under the src/ruby/ directory. The directory is created for you when the plugin is installed. Ruby source files in a Grails project should have the .rb extension.

For example, src/ruby/hello_world.rb might look like this:

class RubyHelloWorld
    def create_greeting(name, greeting)
        time =
        day = time.strftime("%A")
        "#{greeting} #{name}! Today is #{day}."

def greet(name, greeting) hello_world = hello_world.create_greeting(name, greeting) end

With that code in place, the greet function may be executed by using the dynamic property named ruby from any Grails artifact. See below:

class HomeController {
    def hi() {
        ruby.put('name', 'Bobby')
        ruby.put('greeting', 'Hi')
        render ruby.eval('greet($name, $greeting)')

def bye() { ruby.put('name', 'Bobby') ruby.put('greeting', 'Bye') render ruby.eval('greet($name, $greeting)') } }

The Dynamic Property

The dynamic property will be named ruby by default. In a future version of the plugin, this property name will be configurable.
