BlockChain

Makes it easy to chain nested blocks together without creating a ton of nesting.

Installation

Install as usual: gem install block_chain or add gem 'block_chain' to your Gemfile.

Turn this:

foo do
  bar do
    baz do
      qux do
        yield
      end
    end
  end
end

into this:

require 'block_chain'
BlockChain.new(method(:foo), method(:bar), method(:baz), method(:qux)).call { yield }

or:

require 'block_chain'
methods = [:foo, :bar, :baz, :qux].map { |name| method name }
BlockChain.new(*methods).call { yield }

This can make deeply-nested block wrappings a bit more digestable.
