Return the receiver associated with this FrozenError exception.

Invokes Module.prepend_features on each parameter in reverse order.

Refine mod in the receiver.

Returns a module, where refined methods are defined.

Returns an array of Refinement defined within the receiver.

module A
  refine Integer do
  end

  refine String do
  end
end

p A.refinements

produces:

[#<refinement:Integer@A>, #<refinement:String@A>]

Returns the list of Modules nested at the point of call.

module M1
  module M2
    $a = Module.nesting
  end
end
$a           #=> [M1::M2, M1]
$a[0].name   #=> "M1::M2"

In the first form, returns an array of the names of all constants accessible from the point of call. This list includes the names of all modules and classes defined in the global scope.

Module.constants.first(4)
   # => [:ARGF, :ARGV, :ArgumentError, :Array]

Module.constants.include?(:SEEK_SET)   # => false

class IO
  Module.constants.include?(:SEEK_SET) # => true
end

The second form calls the instance method constants.

Registers filename to be loaded (using Kernel::require) the first time that const (which may be a String or a symbol) is accessed in the namespace of mod.

module A
end
A.autoload(:B, "b")
A::B.doit            # autoloads "b"

If const in mod is defined as autoload, the file name to be loaded is replaced with filename. If const is defined but not as autoload, does nothing.

Returns filename to be loaded if name is registered as autoload in the namespace of mod or one of its ancestors.

module A
end
A.autoload(:B, "b")
A.autoload?(:B)            #=> "b"

If inherit is false, the lookup only checks the autoloads in the receiver:

class A
  autoload :CONST, "const.rb"
end

class B < A
end

B.autoload?(:CONST)          #=> "const.rb", found in A (ancestor)
B.autoload?(:CONST, false)   #=> nil, not found in B itself

The equivalent of included, but for prepended modules.

module A
  def self.prepended(mod)
    puts "#{self} prepended to #{mod}"
  end
end
module Enumerable
  prepend A
end
 # => prints "A prepended to Enumerable"

Prevents further modifications to mod.

This method returns self.

Returns a string representing this module or class. For basic classes and modules, this is the name. For singletons, we show information on the thing we’re attached to as well.

Returns an array of the names of the constants accessible in mod. This includes the names of constants in any included modules (example at start of section), unless the inherit parameter is set to false.

The implementation makes no guarantees about the order in which the constants are yielded.

IO.constants.include?(:SYNC)        #=> true
IO.constants(false).include?(:SYNC) #=> false

Synonym for $stdin.

Synonym for $stdout.

Returns a new Date object formed fom the arguments.

With no arguments, returns the date for January 1, -4712:

Date.ordinal.to_s # => "-4712-01-01"

With argument year, returns the date for January 1 of that year:

Date.ordinal(2001).to_s  # => "2001-01-01"
Date.ordinal(-2001).to_s # => "-2001-01-01"

With positive argument yday == n, returns the date for the nth day of the given year:

Date.ordinal(2001, 14).to_s # => "2001-01-14"

With negative argument yday, counts backward from the end of the year:

Date.ordinal(2001, -14).to_s # => "2001-12-18"

Raises an exception if yday is zero or out of range.

See argument start.

Related: Date.jd, Date.new.

Returns a new Date object constructed from the present date:

Date.today.to_s # => "2022-07-06"

See argument start.

Returns a hash of values parsed from string according to the given format:

Date._strptime('2001-02-03', '%Y-%m-%d') # => {:year=>2001, :mon=>2, :mday=>3}

For other formats, see Formats for Dates and Times. (Unlike Date.strftime, does not support flags and width.)

Related: Date.strptime (returns a Date object).

Returns a new Date object with values parsed from string, according to the given format:

Date.strptime('2001-02-03', '%Y-%m-%d')  # => #<Date: 2001-02-03>
Date.strptime('03-02-2001', '%d-%m-%Y')  # => #<Date: 2001-02-03>
Date.strptime('2001-034', '%Y-%j')       # => #<Date: 2001-02-03>
Date.strptime('2001-W05-6', '%G-W%V-%u') # => #<Date: 2001-02-03>
Date.strptime('2001 04 6', '%Y %U %w')   # => #<Date: 2001-02-03>
Date.strptime('2001 05 6', '%Y %W %u')   # => #<Date: 2001-02-03>

Related: Date._strptime (returns a hash).

Returns the Julian start date for calendar reform; if not an infinity, the returned value is suitable for passing to Date#jd:

d = Date.new(2001, 2, 3, Date::ITALY)
s = d.start     # => 2299161.0
Date.jd(s).to_s # => "1582-10-15"

d = Date.new(2001, 2, 3, Date::ENGLAND)
s = d.start     # => 2361222.0
Date.jd(s).to_s # => "1752-09-14"

Date.new(2001, 2, 3, Date::GREGORIAN).start # => -Infinity
Date.new(2001, 2, 3, Date::JULIAN).start    # => Infinity

See argument start.

Calls the block with specified dates; returns self.

• The first date is self.

• Each successive date is date + step, where step is the numeric step size in days.

• The last date is the last one that is before or equal to limit, which should be a Date object.

Example:

limit = Date.new(2001, 12, 31)
Date.new(2001).step(limit){|date| p date.to_s if date.mday == 31 }

Output:

"2001-01-31"
"2001-03-31"
"2001-05-31"
"2001-07-31"
"2001-08-31"
"2001-10-31"
"2001-12-31"

Returns an Enumerator if no block is given.

Equivalent to step with arguments max and 1.

Equivalent to step with arguments min and -1.

Returns a string representation of the date in self in ISO 8601 extended date format ('%Y-%m-%d'):

Date.new(2001, 2, 3).to_s # => "2001-02-03"

Returns a string representation of the date in self, formatted according the given format:

Date.new(2001, 2, 3).strftime # => "2001-02-03"

For other formats, see Formats for Dates and Times.

Creates a DateTime object denoting the given ordinal date.

DateTime.ordinal(2001,34) #=> #<DateTime: 2001-02-03T00:00:00+00:00 ...>
DateTime.ordinal(2001,34,4,5,6,'+7')
                          #=> #<DateTime: 2001-02-03T04:05:06+07:00 ...>
DateTime.ordinal(2001,-332,-20,-55,-54,'+7')
                          #=> #<DateTime: 2001-02-03T04:05:06+07:00 ...>
