00:17 <johnjaye> in ruby if I want an object to take a block like a { |x| ...x } type thing do I include Enumerable and define the 'each' method?

00:17 <johnjaye> i think this is true but i don't know if the docs say that explicitly anywhere

00:20 eddof13_ has quit [Quit: My MacBook Air has gone to sleep. ZZZzzz…]

00:23 <leftylink> *any* function can take a block. Enumerable and each have nothing to do with it

00:24 <leftylink> pandabot rb def foo; end; foo { :my_awesome_block }

00:24 <pandabot> nil - https://carc.in/#/r/fqpy

00:24 <leftylink> see? foo took a block

00:25 <johnjaye> well this is an object

00:25 <johnjaye> but i see what you mean

00:27 seydar has joined #ruby

00:28 <johnjaye> namely i was lookging in gemspec file and saw it says Gem::Specification.new do { ...

00:28 <johnjaye> so I assumed it was related to Enumerable somehow. unless it just goes over all instance variables or something

00:29 hexology has quit [*.net *.split]

00:29 eddof13 has joined #ruby

00:29 <leftylink> then we look in `initialize` for that. it's not uncommon for `initialize` to `yield self` to allow arbitrary code to be run on the object

00:32 Cork has joined #ruby

00:32 seydar has quit [Ping timeout: 245 seconds]

00:33 <leftylink> of course, initialize may very well choose to yield something other than self. that's the decision of the author of the class.

00:33 <leftylink> and what API the class wants to offer.

00:35 <johnjaye> oh ok

00:53 <leftylink> hmmm.... if someone has sabotaged one of my classes by redefining new and allocate, is there still a way I can get an instance of that class?

00:53 <leftylink> pandabot rb class C; def self.new; :sabotaged end; def self.allocate; :sabotaged end; def goal; :congrats end end; C.new.goal

00:54 <pandabot> stderr: -e:2:in `<main>': undefined method `goal' for :sabotaged:Symbol (NoMethodError) - exit 1 - https://carc.in/#/r/fqqa

00:54 <leftylink> anything that can go in place of `C.new.goal` to correctly call goal here?

00:55 egality has quit [Remote host closed the connection]

00:58 <leftylink> okay, I guess we can just remove_method the sabotage. I'll accept that answer

00:58 <leftylink> pandabot rb class C; def self.new; :sabotaged end; def self.allocate; :sabotaged end; def goal; :congrats end end; class C; class << self; remove_method(:new) end end; C.new.goal

00:58 <pandabot> :congrats - https://carc.in/#/r/fqqd

00:58 <leftylink> congrats

01:08 <leftylink> is it valid Ruby syntax to remove that second class C?

01:08 <leftylink> pandabot rb class C; def self.new; :sabotaged end; def self.allocate; :sabotaged end; def goal; :congrats end end; class << C; remove_method(:new) end; C.new.goal

01:08 <pandabot> :congrats - https://carc.in/#/r/fqqi

01:08 <leftylink> oh it is. okay, great.

01:19 keb has quit [Quit: Leaving]

01:20 <leftylink> now my enemies won't be able to sabotage me anymore, for if they try, I will have a ready answer for them and be able to foil their plan

01:21 <leftylink> https://docs.ruby-lang.org/en/master/syntax/modules_and_classes_rdoc.html#label-Singleton+Classes

01:22 <leftylink> wasn't there some conference talk that discusses this?

01:23 <leftylink> it was like a story of two people one who copied the other but didn't really understand what was going on

01:30 <leftylink> ahhhhh found it

01:30 <leftylink> it's "The Case of the Missing Method -- A Ruby Mystery Story"
