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

I wrote a class that handles this exact issue, and deals with things like @instance_variable access, nesting, and so forth. Here's the write-up from another question:
