01:27 <raz> hmm. that Iterator sample code almost tempts me to take another stab at parallel fetching for `shards`

01:27 <FromGitter> <Blacksmoke16> there is an `.of` method

01:28 <FromGitter> <Blacksmoke16> not documenting, but i think thats somewhat related to what its used for

01:28 <FromGitter> <Blacksmoke16> creating an iterator of an existing obj or block

02:37 <raz> i think i've asked this before. is there a way to detect if my code is running under spec?

03:14 <FromGitter> <nanobowers> This article ⏎ https://patshaughnessy.net/2021/11/29/find-your-languages-primitives ⏎ does a dive into crystal arrays (with some comparison to ruby)

04:38 <FromGitter> <Daniel-Worrall> Raz you can check if the Spec constant is defined

04:39 <raz> ahhh good idea. thanks!

04:40 <FromGitter> <Daniel-Worrall> E.g. ⏎ {% skip_file if @top_level.has_constant? "Spec" %}

04:40 <FromGitter> <Blacksmoke16> whats the use case?

04:41 <FromGitter> <Daniel-Worrall> My use case was specing my runnable socks

04:41 <FromGitter> <Daniel-Worrall> AoCs

04:46 <FromGitter> <Blacksmoke16> could you define whatever within `spec_helper`?

04:46 <FromGitter> <Blacksmoke16> that file is only loaded in spec context

04:55 <raz> well i don't want to monkey patch around too much. checking if `Spec` is defined is perfect

04:55 <raz> (i feel like i've even done that before but then forgot about it)

13:15 <FromGitter> <karan718> Hello ⏎ ⏎ Is it possible to define methods on generic classes. ⏎ For example, Is it possible to define an instance method called 'join' which takes instance of Array(String) as receiver but not instances of Array(T) ⏎ ... [https://gitter.im/crystal-lang/crystal?at=61d6eb67f5a3947800efff3a]

14:20 <FromGitter> <Blacksmoke16> @karan718 i think you have a few options depending on your exact context

14:21 <FromGitter> <Blacksmoke16> like I'm assuming you want this method on a custom type that wraps an array?

14:31 <FromGitter> <karan718> @Blacksmoke16 ⏎ I would like for all the methods are that are defined for Array(T) to be available on this custom type. ⏎ I tried doing something like ⏎ `class ArrayOfStrings < Array(String) ⏎ ... [https://gitter.im/crystal-lang/crystal?at=61d6fd3c2a210c38c1b565f1]

14:31 <FromGitter> <Blacksmoke16> i would suggest *not* extending the base array type and instead have a type that wraps the array. like a decorator

14:32 <FromGitter> <Blacksmoke16> then you could force it to only accept an `Array(String)`

14:32 <FromGitter> <karan718> @Blacksmoke16 can you point me to some documentation or example that uses this pattern

14:33 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=61d6fdc6d143b14f83032c8f]

14:33 <FromGitter> <Blacksmoke16> something like that

14:34 <FromGitter> <Blacksmoke16> may need to make it `getter array : Array(String)` as you wouldnt be able to pass it to things restricted to `Array`

14:39 <FromGitter> <karan718> I will give this a shot and get back to you. ⏎ How did you become familiar with the concept of `forward_missing_to` ? ⏎ Also, why do recommend against extending the base array type?

14:41 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/Object.html#forward_missing_to(delegate)-macro it's in the API docs

14:44 <FromGitter> <karan718> Thanks @Blacksmoke16

14:44 <FromGitter> <Blacksmoke16> and i cant find the specific issue (if there is one), but afaik in the past it just causes issues

14:44 <FromGitter> <Blacksmoke16> same with any of the built in collection types

20:45 <FromGitter> <amk:amk.ie> howdy, is there method to iterate over and recurse through a directory? I've found .each and stuff but they dont seem to recurse according to the docs

20:52 <FromGitter> <Blacksmoke16> probably want something in https://crystal-lang.org/api/master/Dir.html

20:52 <FromGitter> <Blacksmoke16> `Dir.glob` maybe
