00:27 <rocx> b'guh. wasn't there an update not too long ago that said the compiler could "downgrade" integer types (eg. turning `3` into a `UInt8` if i declared the type to be such?

00:27 <FromGitter> <Blacksmoke16> in some cases yea

00:28 <rocx> urgh. i decide to use UInt8s just to save a smidge of memory and turns out it's a lot of type annotating and .to_u8 calls.

00:28 <FromGitter> <Blacksmoke16> unless you have a reason to do it, better to just use Int32

00:29 <rocx> shaving a whole three bytes per integer but that might just be munchkining on memory.

00:29 <FromGitter> <Blacksmoke16> benchmark it and find out

00:29 <FromGitter> <Blacksmoke16> otherwise its just premature optmization

00:30 <rocx> and we all know premature optimization is the root of all evil.

00:31 <FromGitter> <moe:busyloop.net> crystal tries to help you resist the munchkining, by making it annoying

00:32 <rocx> fair. then again, having a type system like this be annoying before running the code would have saved me the months of all the jira tickets saying "unexpected method for NilClass".

00:32 <FromGitter> <Blacksmoke16> there's also a compile time flag you can use to make it more strict

00:33 <FromGitter> <Blacksmoke16> allows it to autocast number literals, but not expressions

00:33 <FromGitter> <Blacksmoke16> e.g. `foo 10` would work but not `foo 5 +5`

00:33 <FromGitter> <moe:busyloop.net> ah yea, good ol' masochist mode

00:34 <FromGitter> <moe:busyloop.net> for next april we should add a go-lang mode that forces you to put `if err` after each line :p

19:43 <FromGitter> <azurelmao> I've come across a weird issue. I'm using the Crystal IDE plugin for IntelliJ and the run command works fine

19:44 <FromGitter> <azurelmao> But when I tried to run it in the terminal, it doesn't

19:45 <FromGitter> <azurelmao> says it can't find a required file, and that i should chrck whether im running the compiler in the same directory as my shard.yml

19:45 <FromGitter> <azurelmao> which I am

21:44 <FromGitter> <Blacksmoke16> whats the exact error?

22:07 <FromGitter> <plambert> Is it possible to write a module Foo, such that it can wrap the initialize() methods of any class that includes it?

22:09 <FromGitter> <Blacksmoke16> got an example?

22:10 <FromGitter> <moe:busyloop.net> `included`-hook is probably what you're looking for. ⏎ https://crystal-lang.org/reference/1.6/syntax_and_semantics/macros/hooks.html

22:11 <FromGitter> <moe:busyloop.net> depending on what you mean by "wrap" in detail, some additional gymnastics with or without macros may be needed

22:11 <FromGitter> <plambert> https://gist.github.com/plambert/c9431fd48306dceb868c9d5f5b512c18

22:12 <FromGitter> <plambert> Basically, I want my "singleton" module to make sure every initialize method ends (or starts) with `@@singleton ||= self`

22:13 <FromGitter> <plambert> I think I could do it by re-implementing `new`, since there's only one of those… but it seemed like there should be a way to do it to the initialize methods themselves…

22:13 <FromGitter> <plambert> (This is a learning project, so while I'm happy to hear of better ways to do this, or of existing shards I could use, I also still want to figure out if it's possible to do this…) :)

22:14 <FromGitter> <Blacksmoke16> try something like

22:14 <FromGitter> <plambert> I'm trying to extract the singleton parts of that class into a module, since I'll be doing all the same things to many classes in this project. And it's all easy, except the `@@singleton ||= self`

22:15 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=63868473bcdb0060b8446cbc]

22:16 <FromGitter> <plambert> Cool

22:16 <FromGitter> <Blacksmoke16> tho might need to include it after the concrete one?

22:16 <FromGitter> <plambert> And if there are multiple initialize() methods with arbitrary arguments?

22:16 <FromGitter> <Blacksmoke16> prob out of luck

22:17 <FromGitter> <plambert> So… in the docs say "don't forget to add @@singleton ||= self"

22:17 <FromGitter> <plambert> (And maybe give it a fancy name like register_singleton)

22:17 <FromGitter> <plambert> :)

22:17 <FromGitter> <plambert> I love Crystal's macros, but eventually they become a source of great neurological recursion, and I can't figure them out. :)

22:18 <FromGitter> <plambert> Thank god for `{{ debug }}`

22:36 <FromGitter> <Blacksmoke16> could try having an abstract parent class where they could just call `super`

22:36 <FromGitter> <Blacksmoke16> tho that might set the class var of all children and not just that one

22:43 <FromGitter> <azurelmao> > whats the exact error? ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=63868b02f9491f62c9d7c5d6]

22:43 <FromGitter> <Blacksmoke16> and you have a `src/Server.cr`?

22:43 <FromGitter> <Blacksmoke16> tho fwiw, file names should be all lowercase

22:43 <FromGitter> <azurelmao> Server is in the src folder, the same as crystal-cave.cr

22:44 <FromGitter> <azurelmao> yeah I know, but I don't like some naming conventions

22:44 <FromGitter> <Blacksmoke16> if its in the same dir, you need to do like `./server`

22:44 <FromGitter> <Blacksmoke16> so `require "./Server"`

22:44 <FromGitter> <azurelmao> weird

22:44 <FromGitter> <azurelmao> the IDE plugin doesn't complain when it's just "Server"

22:45 <FromGitter> <Blacksmoke16> well you're the first i heard using that plugin so apparently it needs some work 😅

22:45 <FromGitter> <Blacksmoke16> its basically assuming its a shard and is looking for it in `lib/`

22:45 <FromGitter> <azurelmao> lol, I use it cause I already have IntelliJ for minecraft mods

22:45 <FromGitter> <Blacksmoke16> like whats the output of `crystal env CRYSTAL_PATH`

22:45 <FromGitter> <Blacksmoke16> as that's where it will look

22:46 <FromGitter> <azurelmao> `CRYSTAL_PATH=lib:/usr/bin/../share/crystal/src`

22:46 <FromGitter> <Blacksmoke16> so the error is correct in that it cant be found, hence needing to use `./Server`

22:46 <FromGitter> <Blacksmoke16> https://crystal-lang.org/reference/1.6/syntax_and_semantics/requiring_files.html

22:49 <FromGitter> <azurelmao> so I should move my other files to lib/ ?

22:49 <FromGitter> <Blacksmoke16> no

22:49 <FromGitter> <Blacksmoke16> you should require it via `require "./Server"`

22:49 <FromGitter> <Blacksmoke16> and not `require "Server"`

22:50 <FromGitter> <azurelmao> kinda looks ugly but alright

22:50 <FromGitter> <azurelmao> thank you

22:50 <FromGitter> <Blacksmoke16> np
