DslBlock

DslBlock allows you to use classes to define blocks with commands for a Domain Specific Language. The commands are automatically relayed to your instance method.

Installation

Add this line to your application's Gemfile:

gem 'dsl_block'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dsl_block

Usage

class Foo < DslBlock
  commands :show_foo
  def show_foo(x)
    puts "Mr. T says you are a foo times #{x.to_i}"
  end
end

class Bar < DslBlock
  commands :show_bar
  def show_bar(x)
    puts "Ordering #{x.to_i} Shirley Temples from the bar"
  end
end

class Baz < DslBlock
  commands :show_baz
  def show_baz(x)
    puts "Baz spaz #{x.inspect}"
  end
end

Baz.add_command_to(Bar)
Bar.add_command_to(Foo, true)
Foo.add_command_to(self)


foo do
  puts self.inspect       # => #<Foo:0x007f98f187e240 @block=#<Proc:0x...>, @parent=nil>
  x = 10/10
  show_foo x              # => Mr. T says you are a foo times 1

  bar do
    x *= 2
    show_bar x            # => Ordering 2 Shirley Temples from the bar
    x += 1
    show_foo x            # => Mr. T says you are a foo times 3

    baz do
      x *= 4
      x /= 3
      show_baz x          # => Baz spaz 4
      begin
        x += 1
        show_bar 5        # This will throw a NameError
      rescue NameError
        puts 'No bar for us'
      end

    end

  end

end
