DSLKit::Interpreter

Interpret the string source as a body of a block, while passing *args into the block.

A small example explains how the method is supposed to be used and how the *args can be fetched:

 class A
   include DSLKit::Interpreter
   def c
     3
   end
 end

 A.new.interpret('|a,b| a + b + c', 1, 2) # => 6

To use a specified binding see interpret_with_binding.

# File lib/dslkit/polite.rb, line 206
    def interpret(source, *args)
      interpret_with_binding(source, binding, *args)
    end

Interpret the string source as a body of a block, while passing *args into the block and using my_binding for evaluation.

A small example:

 class A
   include DSLKit::Interpreter
   def c
     3
   end
   def foo
     b = 2
     interpret_with_binding('|a| a + b + c', binding, 1) # => 6
   end
 end
 A.new.foo # => 6

      end
      block = lambda { |*a| eval("lambda { #{source} }", my_binding, path).call(*a) }
