def self.calldata(
  method,
  argc = 0,
  flags = CallData::CALL_ARGS_SIMPLE,
  kw_arg = nil
)
  CallData.new(method, argc, flags, kw_arg)
end

compile(source, options = Compiler::Options.new) click to toggle source

Compile the given source into a YARV instruction sequence.

# File lib/syntax_tree/yarv.rb, line 25
def self.compile(source, options = Compiler::Options.new)
  SyntaxTree.parse(source).accept(Compiler.new(options))
end

interpret(source, options = Compiler::Options.new) click to toggle source

Compile and interpret the given source.

# File lib/syntax_tree/yarv.rb, line 30
def self.interpret(source, options = Compiler::Options.new)
  iseq = RubyVM::InstructionSequence.compile(source, **options)
  iseq = InstructionSequence.from(iseq.to_a)
  VM.new.run_top_frame(iseq)
