Ruby example for converting strings into primitive types

convert_strings.rb

boolean_converter = ->(s){ s == "true" ? true : false}
type_converters = {Fixnum => ->(s){s.to_i}, Float => ->(s){s.to_f}, Date => ->(s){s.to_date},
                  TrueClass => boolean_converter, FalseClass => boolean_converter, String => ->(s){s}}


puts type_converters[Fixnum]["100"]
puts type_converters[Float]["100"]
puts type_converters[Date]["100"]
puts type_converters[TrueClass]["true"]
puts type_converters[FalseClass]["true"]
