NAME

       Catmandu::Fix::Condition::in - only execute fixes the data in one path is contained in
       another

SYNOPSIS

          #-------------------------------------------------------------------
          # Compare single values
          # foo => 42 , bar => 42 => in(foo,bar) -> true
          if in(foo,bar)
             add_field(forty_two,ok)
          end

          # When comparing single values to an array: test if the value is
          # contained in the array

          # foo => 1 , bar => [3,2,1]  => in(foo,bar) -> true
          if in(foo,bar)
             add_field(test,ok)
          end

          # foo => 42 , bar => [1,2,3] => in(foo,bar) -> false
          unless in(foo,bar)
             add_field(test,ok)
          end

          # In the following examples we'll write in pseudo code the true/false
          # values of some 'in()' comparissons

          # scalars vs arrays - check if the value is in the array
          foo: 42 , bar: [1,2,3]                   in(foo,bar) -> false
          foo: 1  , bar: [1,2,3]                   in(foo,bar) -> true

          # scalars vs hashes - check if the key is in the hash
          foo: name , bar: { name => 'Patrick' }           in(foo,bar) -> true
          foo: name , bar: { deep => {name => 'Nicolas'}}  in(foo,bar) -> false

          # array vs array - check if the contents is equal
          foo: [1,2] , bar: [1,2]                  in(foo,bar) -> true
          foo: [1,2] , bar: [1,2,3]                in(foo,bar) -> false
          foo: [1,2] , bar: [[1,2],3]              in(foo,bar) -> false
