JRuby - The Ruby Programming Language on the JVM

JRuby is a 100% Java implementation of the Ruby programming language. It is Ruby for the JVM.

JRuby provides a complete set of core "builtin" classes and syntax for the Ruby language, as well as most of the Ruby

Standard Libraries. The standard libraries are mostly Ruby's own complement of `.rb` files, but a few that depend on

C language-based extensions have been reimplemented.

## Features

* aims to provide a complete, correct and fast implementation of Ruby

* concurrency without a global-interpreter-lock

* true parallelism

* embed a JRuby interpreter into any Java application

* tight integration with the Java language to allow the use of Java classes in your Ruby program

* full two-way access between Java and Ruby code


## Package Parameters

* `/AddToDesktop` - adds a desktop shortcut for the JRuby IRB Console

e.g. `choco install -y jruby --package-parameters="/AddToDesktop"`

* `/InstallDir` - sets the directory in which to install JRuby. The installation defaults to `C:\Tools\jrubyXY` where XY are the major and minor version parts

e.g. `choco install -y jruby --package-parameters="/InstallDir:C:\Tools\jruby"`

* `/NoPath` - do not add the jruby bin folder to the user PATH

e.g. `choco install -y jruby --package-parameters="/NoPath"`

To have Chocolatey remember parameters on upgrade, be sure to set `choco feature enable -n=useRememberedArgumentsForUpgrades`.
