Re-composes a prime factorization and returns the product.

Same as Enumerator#with_index(0), i.e. there is no starting offset.

If no block is given, a new Enumerator is returned that includes the index.

Returns the Ruby source filename and line number containing first definition of constant specified. If the named constant is not found, nil is returned. If the constant is found, but its source location can not be extracted (constant is defined in C code), empty array is returned.

inherit specifies whether to lookup in mod.ancestors (true by default).

# test.rb:
class A
  C1 = 1
end

module M
  C2 = 2
end

class B < A
  include M
  C3 = 3
end

class A # continuation of A definition
end

p B.const_source_location('C3')           # => ["test.rb", 11]
p B.const_source_location('C2')           # => ["test.rb", 6]
p B.const_source_location('C1')           # => ["test.rb", 2]

p B.const_source_location('C2', false)    # => nil  -- don't lookup in ancestors

p Object.const_source_location('B')       # => ["test.rb", 9]
p Object.const_source_location('A')       # => ["test.rb", 1]  -- note it is first entry, not "continuation"

p B.const_source_location('A')            # => ["test.rb", 1]  -- because Object is in ancestors
p M.const_source_location('A')            # => ["test.rb", 1]  -- Object is not ancestor, but additionally checked for modules

p Object.const_source_location('A::C1')   # => ["test.rb", 2]  -- nesting is supported
p Object.const_source_location('String')  # => []  -- constant is defined in C code

Removes the definition of the sym, returning that constant’s value.

class Dummy
  @@var = 99
  puts @@var
  remove_class_variable(:@@var)
  p(defined? @@var)
end

produces:

99
nil

Returns the value of the given class variable (or throws a NameError exception). The @@ part of the variable name should be included for regular class variables. String arguments are converted to symbols.

class Fred
  @@foo = 99
end
Fred.class_variable_get(:@@foo)     #=> 99
