Issue #18190 has been updated by Eregon (Benoit Daloze). To clarify, random/formatter is now a stdlib (not loaded by default). `Random::Formatter` is defined in core but has few methods before `require 'random/formatter'`: ``` $ ruby -e 'puts Random::Formatter.instance_methods(false)' rand random_number $ ruby -rrandom/formatter -e 'puts Random::Formatter.instance_methods(false)' random_number uuid rand alphanumeric hex random_bytes base64 urlsafe_base64 ``` ---------------------------------------- Feature #18190: Split `Random::Formatter` from securerandom https://bugs.ruby-lang.org/issues/18190#change-101184 * Author: nobu (Nobuyoshi Nakada) * Status: Closed * Priority: Normal ---------------------------------------- Now `Random::Formatter` methods are defined in `securerandom.rb`, since it was split from `SecureRandom` module historically. However this module does not need to be `SecureRandom` but just to respond to `bytes` method. I propose to move `Random::Formatter` module to another file, `random_formatter.rb` or `random/formatter.rb`. And keep only that file in ruby core and remove from securerandom library in future. -- https://bugs.ruby-lang.org/
