[ruby-talk:444825] Pattern matching as String, passing patters to functions
by Marcus Poller 01 Jun '26

01 Jun '26

Hi Rubyists, is this the place to ask beginner questions? I am confused about pattern matching. It only seems to work when the key is of type symbol. How would I apply pattern matching to string keys? Example require "yaml" yaml_data=" cards_on_hand: - suite: hearts value: '9' - suite: hearts value: 'king' - suite: diamonds value: 'king' " y=YAML.safe_load(yaml_data, symbolize_names: true) puts y.inspect y[:cards_on_hand].each do |a_card| case a_card in { suite: String => captured_suite, value: 'king' } puts "you have a king on your hand and its suite is #{captured_suite}" else puts "a card of no interest #{a_card.inspect}" end end {cards_on_hand: [{suit: "hearts", value: "9"}, {suit: "hearts", value: "king"}, {suit: "diamonds", value: "king"}]} a card of no interest {suite: "hearts", value: "9"} you have a king on your hand and its suite is hearts you have a king on your hand and its suite is diamonds Second question: Since everything in Ruby is an object, how do I pass patterns into a function? Even more specific, how do I handle capture when passing to a function? Cheers, Marcus

[ruby-talk:444822] [ANN] minitest-autotest 1.2.2 Released
by Ryan Davis 13 May '26

13 May '26

minitest-autotest version 1.2.2 has been released! * home: <https://github.com/seattlerb/minitest-autotest> * rdoc: <http://docs.seattlerb.org/minitest-autotest> autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead. ## Features/Problems: * Continually and intelligently test only those files you change with autotest. Changes: ### 1.2.2 / 2026-05-13 * 3 bug fixes: * Fix shebang and use require_relative for bin/autotest. * Fixed Autotest.run to process options before path_expander. * MT6: Fixed loading of minitest/server.
