A quick example for #ruby IRC of yomikomu-like compiling Ruby to YARB IR bytecode, caching it to disk, then loading and evaling it later.

yarb.rb

require 'zlib'

path = 'example.rb'

##
# Compile and cache Ruby binary to disk.
binary = RubyVM::InstructionSequence.compile_file(path).to_binary
binary_path = "#{path}.yarb.gz"
Zlib::GzipWriter.open(binary_path) do
  _1.write(binary)
end

##
# Load and eval cached a Ruby compiled binary.
Zlib::GzipReader.open(binary_path) do
  RubyVM::InstructionSequence.load_from_binary(_1.read).eval
end
