`Random` number formatter.

Formats generated random numbers in many manners.

Examples

Generate random hexadecimal strings:

require 'random/formatter'

prng.hex(10) #=> "52750b30ffbc7de3b362"
prng.hex(10) #=> "92b15d6c8dc4beb5f559"
prng.hex(13) #=> "39b290146bea6ce975c37cfc23"

Generate random base64 strings:

prng.base64(10) #=> "EcmTPZwWRAozdA=="
prng.base64(10) #=> "KO1nIU+p9DKxGg=="
prng.base64(12) #=> "7kJSM/MzBJI+75j8"

Generate random binary strings:

prng.random_bytes(10) #=> "\016\t{\370g\310pbr\301"
prng.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"

Generate alphanumeric strings:

prng.alphanumeric(10) #=> "S8baxMJnPl"
prng.alphanumeric(10) #=> "aOxAg8BAJe"

Generate UUIDs:

prng.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594"
prng.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"

Generate a random number in the given range as Random does

prng.random_number       #=> 0.5816771641321361
prng.random_number(1000) #=> 485
prng.random_number(1..6) #=> 3
prng.rand                #=> 0.5816771641321361
prng.rand(1000)          #=> 485
prng.rand(1..6)          #=> 3

Gem::Deprecate

Provides 3 methods for declaring when something is going away.

+deprecate(name, repl, year, month)+:

Indicate something may be removed on/after a certain date.

+rubygems_deprecate(name, replacement=:none)+:

Indicate something will be removed in the next major RubyGems version,
and (optionally) a replacement for it.

rubygems_deprecate_command:

Indicate a RubyGems command (in +lib/rubygems/commands/*.rb+) will be
removed in the next RubyGems version.

Also provides skip_during for temporarily turning off deprecation warnings. This is intended to be used in the test suite, so deprecation warnings don’t cause test failures if you need to make sure stderr is otherwise empty.

Example usage of deprecate and rubygems_deprecate:

class Legacy
  def self.some_class_method
    # ...
  end

  def some_instance_method
    # ...
  end

  def some_old_method
    # ...
  end

  extend Gem::Deprecate
  deprecate :some_instance_method, "X.z", 2011, 4
  rubygems_deprecate :some_old_method, "Modern#some_new_method"

  class << self
    extend Gem::Deprecate
    deprecate :some_class_method, :none, 2011, 4
  end
end

Example usage of rubygems_deprecate_command:

class Gem::Commands::QueryCommand < Gem::Command
  extend Gem::Deprecate
  rubygems_deprecate_command

  # ...
end

Example usage of skip_during:

class TestSomething < Gem::Testcase
  def test_some_thing_with_deprecations
    Gem::Deprecate.skip_during do
      actual_stdout, actual_stderr = capture_output do
        Gem.something_deprecated
      end
      assert_empty actual_stdout
      assert_equal(expected, actual_stderr)
    end
  end
end

Mixin methods for install and update options for Gem::Commands
