Change the context/binding inside a block in ruby

Question

I have a DSL in Ruby that works like so:

desc \'list all todos\'
command :list do |c|
  c.desc \'show todos in long form\'
  c.switch :l
  c.action do |globa         


        

Answer 1

Paste this code:

  def evaluate(&block)
    @self_before_instance_eval = eval "self", block.binding
    instance_eval &block
  end

  def method_missing(method, *args, &block)
    @self_before_instance_eval.send method, *args, &block
  end
