Overview

Reopen the core Object class to add #identify to all objects.

Instance Method Summary

• #inspect_lit ⇒ String

  Standard #inspect for any object that doesn’t override this method.

Instance Method Details

#identify(*args) ⇒ String #identify(*args, options) ⇒ String

Instance method for constructing a self-identifying string for any given object or list of objects.

Examples:

OpenStruct.new(a: 1, b: '2', c: :"3").identify(:a, :b, :c)
# => "OpenStruct[a:1, b:\"2\", c::\"3\"]"

1.identify(:to_s) # => "Integer[to_s:\"1\"]"
nil.identify      # => "[no objects]"

%w(1 2).identify(:to_i, :to_f)
# => "String[to_i:1, to_f:1.0], String[to_i:2, to_f:2.0]"

(1..10).to_a.identify(:to_f, limit: 2)
# => "Integer[to_f:1.0], Integer[to_f:2.0], ... (8 more)"

Overloads:

• #identify(*args) ⇒ String

  Parameters:

  • args (*) —

    (optional) a list of arguments to identify for this object or for each object in this collection

• #identify(*args, options) ⇒ String

  Parameters:

  • args (*) —

    (optional) (default: :id) a list of arguments to identify for this object

  • options (Hash) —

    the options for building a customized self-identifier

  Options Hash (options):

  • :klass (String, nil) —

    object class name override

  • :limit (Integer) —

    maximum number of objects to display from a collection

Returns:

• (String) —

  a self-identifying string

def identify(*args, **kargs)
  ObjectIdentifier::Identifier.identify(self, *args, **kargs)
end

#inspect_lit ⇒ String

Standard #inspect for any object that doesn’t override this method. This method is meant to make an object’s type inherently obvious inspected.

Returns:

• (String) —

  a String-literal representation of this object

# File 'lib/core_ext/object.rb', line 9
