another toy Ruby implementation with a fast JIT compiler written in Rust.

• register-based bytecode.
• bytecode executer (virtual machine) written in x86-64 assembly (yes, we currently support only x86-64!).
• a compact and fast just-in-time compiler. (internally using self-made dynamic assembler monoasm)

This project still remains in early-alpha stage. Currently, only the functionalities described below are implemented.

• classes: Object, Integer, Float, String, Symbol, Class, Array
• superclass and singleton class and methods
• local variables
• instance variables & accessor
• block and dynamic local variables
• if-then-elsif-end statement
• for-in statement
• while/until statement and postfix while/until modifier
• method definition
  • required parameter
  • optional parameter
  • rest parameter
• class definition

• measured by benchmark-driver with '--repeat-count 3' option.
• benchmark codes are in the official repo except qsort and tarai.
• measurements are shown in iteration/sec (the higher, the better).

To build monoruby, You'll need installation of Rust. Please be aware that only nightly version of Rust works for monoruby.

To run ruby program file on monoruby,

% cargo run test.rb

or

% cargo run --release -- test.rb

one liner

% cargo run -- -e "puts 100"

You can launch REPL.

% ./irm.sh
