00:07 <FromGitter> <watzon> Seems as though Crystal is missing `pack` and `unpack` methods?

00:25 <FromGitter> <aemadrid> it looks like you are right @watzon

00:29 <FromGitter> <watzon> Really I just need to be able to convert an `Int` to a `ByteArray`. So really, `1024` should be converted to `[4, '0']`

00:29 <FromGitter> <watzon> I think :/

00:41 <FromGitter> <watzon> Figured it out! I think this would do well in the stdlib ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5973f0a645fc670746b98362]

01:46 <FromGitter> <watzon> How can I make an array that holds elements of a specific class and it's children in such a way that I can access the methods on it's children that are specific to that child? As an example this (https://play.crystal-lang.org/#/r/2eju) won't run ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5974000d2723db8d5e399b5d]

01:49 <FromGitter> <watzon> I know I can use `.as(Child)`, but that's obviously not ideal

02:34 <FromGitter> <renich> o/

02:42 <FromGitter> <renich> I am playing around with: http://exercism.io/exercises/crystal/hello-world/readme

02:42 <FromGitter> <renich> when I run crystal spec

02:42 <FromGitter> <renich> it says there are two pending tests... why is this?

02:45 <FromGitter> <fridgerator> http://exercism.io/exercises/crystal/hello-world/test-suite

02:45 <FromGitter> <fridgerator> has 2 pending tests

02:45 <FromGitter> <watzon> @renich have you changed the tests in the spec from `pending` to `it` like the instructions say?

02:45 <FromGitter> <renich> errr... no

02:46 <FromGitter> <renich> @watzon good point... hehe

02:46 <FromGitter> <watzon> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=59740e0c4bcd78af56d81f3b]

02:47 <FromGitter> <renich> Yep, did that. they all pass. Thanks a lot.

02:47 <FromGitter> <watzon> No problem haha

02:47 <FromGitter> <watzon> In other news, my very first crystal library is live! https://github.com/watzon/crystal-razer

02:48 <FromGitter> <watzon> Won't help anyone unless you have a razer keyboard, mouse, or trackpad, but it's pretty cool

02:48 <FromGitter> <fridgerator> 👍

02:49 <FromGitter> <renich> cool

02:52 <FromGitter> <renich> Created a crystal team there, if anyone here wants to redirect newbies there: http://exercism.io/teams/cr/streams/tracks/crystal

05:55 <oprypin> watzon, regarding calling specific classes method, i think wrapping it in .responds_to? would work

05:56 <oprypin> i mean wrapping it in an 'if' checking that

05:59 <oprypin> watzon, int to bytes https://crystal-lang.org/api/0.23.0/IO/ByteFormat.html

20:27 <Majost> Has anyone successfully used this docopt shard? https://github.com/chenkovsky/docopt.cr

20:29 <Majost> The code in the readme doesn't seem to work with 0.23.1, and the example seems to be just the spec which is weird

20:55 <FromGitter> <konovod> @Majost `crystal spec` works in 0.23.0. What's an error in 0.23.1?

20:55 <Majost> ah,

20:56 <Majost> I am just starting out and was trying to compile that

20:56 <Majost> hah
