Mirah: Where Java Meets Ruby
summary
Mirah claims to be a Ruby‑like language that compiles to JVM bytecode and targets performance parity with Java; it uses the JRuby parser, transforms JRuby AST into a Mirah AST, and maps symbolic types to the JVM. There is no runtime library — dependencies are chosen per project — and installation requires JRuby 1.7+ and a Mirah gem. Version 0.0.14 (2015) is early but already powers Android apps, has web frameworks like Dubious and tooling such as Pinda, and sees some production use.
