Mirah is a customizable programming language featuring static types, local type inference and a heavily Ruby-inspired syntax. Mirah currently includes a typer/compiler backend for the JVM which can output JVM bytecode.

• Ruby-like syntax
• Compiles to .class
• Fast as Java
• No runtime library

mirah <script.mirah>
mirah -e "inline script"
mirahc <script.mirah>
mirahc -e "inline script" # produces DashE.class

• Java 1.7 or higher.

If your gem and rake are not from JRuby, prefix the commands with jruby -S

$ gem install mirah

Mirah is distributed as a jar through maven central. You can download the latest jar from maven.org.

You can also install Mirah from a zip file. Download the latest stable release from https://github.com/mirah/mirah/releases. Extract it, and add bin to your $PATH to be able to use mirah, mirahc, etc.

Setup building locally and installing from source, you'll need jruby 1.7.12 or higher. Then just follow these commands.

$ git clone http://github.com/mirah/mirah.git
$ cd mirah
$ bundle install

$ rake gem
$ gem install pkg/mirah-*.gem

$ rake dist/mirahc.jar

This will create a mirahc.jar file in dist that you can run to compile mirah source files.
