A simple Ruby-like language, compiler, and virtual machine, written in Ruby
This is a small educational project to make:
- A simple stack-based bytecode virtual machine
- An assembler to compile assembly language to bytecode for the VM
- A compiler to compile a simple Ruby-like language (Nuby) to VM assembly
- A spec for the source language Nuby
I've been working through the book Language Implementation Patterns by Terrence Parr, implementing some of the patterns (to some level of thoroughness) in Ruby. My efforts are in my language_implementation_patterns repository.
I got as far as the virtual machine implementation patterns before deciding I'd like to try making a full compiler pipeline.
Run rake guard and rake bundle to use 1.9.3 where necessary. It doesn't look like rb-fsevent works in Rubinius right now:
➜ nuby irb
require 'rubinius-2.0.0rc1 :001 > require 'rb-fsevent'
=> true
rubinius-2.0.0rc1 :002 > require 'listen'
=> true
rubinius-2.0.0rc1 :003 > Listen.to(".", filter: /\.rb$/) { |m, a, r| puts "Listen:"; p m; p a; p r }
