<potz> Anyone knows if the Hash class keeps items in the same order they were added? I’m inclined to think it doesn’t, but could not find any authoritative answer in the docs...

<Dillybob1992> hey all, i'm getting `(signal 11) ??? (523495 times)` which i checked github and i read that it means it's a stack overflow, but i've been stuck for 3 hours trying to find out way and not sure what i'm doing wrong
<FromGitter>
<Dillybob1992> here is my pastebin: https://pastebin.com/raw/9KM3M9Bz it happens whenever the users << socket is called (i know i could just use the code straight-shoota and rx14 helped me with yesterday), but i feel like this could be a learning moment on what I did wrong so I can avoid the mistakes in future :)

<ArtLinkov> Morning guys. ⏎ I need help with something, let's say I got two class instances, each has an array (which is accessible from outside). I want the second class to take a copy of the array from the first class into it's own class. However, I want to change the array in the second without changing the array in the first. ⏎ I tried something like this: ⏎ class2.array = class1.array ⏎ or class2.array =

<FromGitter>
<ArtLinkov> Hmm... array.dup doesn't work for me. I'm guessing because the array is of class instances (i.e specific neuron)
<FromGitter>
<ArtLinkov> I'll try .clone
<FromGitter>

so it seems crest only works with crystal 0.24.1, but kemal only works with 0.23.1

oh, yes! it seems my shards were just confused

<straight-shoota> might be related to #2713
<FromGitter>
<straight-shoota> class_property creates a class method, but you're using an instance method
<FromGitter>
<straight-shoota> So either `RPG_USER.charachter_name` (class variable) or `property character_name = "Joey"`(instance variable)
<FromGitter>
<Dillybob1992> oh okay :)
<FromGitter>
<Dillybob1992> change to `property`, got it johannes, thanks again ^^

<FromGitter>
<Dillybob1992> hey, got another small little question ⏎ ⏎ ``` code paste, see link``` ⏎ ⏎ i am getting `instance variable '@socket' of RPG_USER must be TCPSocket+:Class, not TCPSocket+` . What does TCPSocket+:Class mean? [https://gitter.im/crystal-lang/crystal?at=5a577d3583152df26d5b802e]
<FromGitter>
<bew> Maybe you meant `property socket : TcpSocket`?
<FromGitter>
<Dillybob1992> Oh wow, yeah
<FromGitter>
<bew> It means that you're storing the class `TCPSocket` not an instance of this class
<FromGitter>
<bew> Well no the other way around but you get it
<FromGitter>
<Dillybob1992> now, am getting `. Indirect initialization is not supported.` Is that because it's only be filled to a TCPSocket when a user joins the server?
<FromGitter>
<Dillybob1992> Oh, look here. I changed it to `property socket = TCPSocket.new` and it worked with no errors. I think I am understanding instanced classes now
<FromGitter>
<hugoabonizio> @Dillybob1992 you can use `property socket : TCPSocket` to avoid creating a new TCPSocket
<FromGitter>
<Dillybob1992> yah, I tried that but I get `instance variable '@socket' of RPG_USER was not initialized directly in all of the 'initialize' methods, rendering it nilable. Indirect initialization is not supported.`
<FromGitter>
<bararchy> @eliasjpr I'll trust github HA and DT over any self hosted community server
<FromGitter>
<hugoabonizio> @Dillybob1992 a solution is to define a `#initialize` method which accepts a socket, like: `def initialize(@socket); end`
<FromGitter>
<hugoabonizio> github is back
<FromGitter>
<Dillybob1992> thanks hugo, i did that and now the error is gone :) i also tested `socket = [] of TCPSocket` and got no error, even without having initialize. i wonder which way is better?
<FromGitter>
<hugoabonizio> `[] of TCPSocket` is equivalent to `Array(TCPSocket).new`, so in this case you are instantiating an Array object
<FromGitter>
<Dillybob1992> O_O i see
<FromGitter>
<Dillybob1992> Ya, i much rather do your way then feels more appropriate
<FromGitter>
<eliasjpr> > @eliasjpr I'll trust github HA and DT over any self hosted community server ⏎ ⏎ Me too :)

jesus christ, crystal code written 5 months ago is that old already?
<ua>
shard written 5 months ago, broken in multiple ways :<
<FromGitter>
<fridgerator> There are breaking changes every crystal release, they are listed in the release notes
<FromGitter>
<Dillybob1992> are there any benchmarks comparing crystal to nodejs via tcp server or websocket performance? just mildly curious because i'm from nodejs and getting kind of fed up with it lately (why im learning crystal)
cbass has quit [Ping timeout: 256 seconds]
<ua>
is it possible to install multiple versions of crystal like with rvm in ruby?
<ua>
also is there something like long term support releases?
<FromGitter>
<fridgerator> what OS are you using? I can switch between crystal versions with brew, but I dont know if thats a good solution
<ua>
ubuntu
<FromGitter>
<fridgerator> There is crenv, but I haven't used it in a while. I dont nkow if its maintained
<FromGitter>
<Fryguy> ua: I think that anyenv supports crystal (haven't used it myself)
<ua>
crenv does work but that shard is still broken lol
<ua>
fridgerator: by LTS i mean more something like consensus among developers about which version to use at that particular moment in time thats not always the latest version
<ua>
lol
<ua>
but yeah at the point where language is still evolving extensively that might not make mech sense yet i guess
DTZUZO has quit [Ping timeout: 255 seconds]
<FromGitter>
<marksiemers> @Fryguy @fridgerator - `crenv` depend on `anyenv` (for their preferred installation anyway). And I install both of them, but there has been no update for the newest version of crystal. So either that will be a manual process to update or someone will have to fork `crenv` or get added as a member of that repo.
DTZUZO has joined #crystal-lang
<FromGitter>
<Fryguy> thanks for the update @marksiemers
<ua>
yes, crenv install 0.24.1 doesnt work
<ua>
but overall it gets stuff from github.com/crystal-lang/crystal/releases
<ua>
it can install 0.24.0 tho which was released after last crenv repo update which was 7 months ago
<FromGitter>
<straight-shoota> ua, until 1.0 you should always use the latest release
<ua>
ok
<FromGitter>
<straight-shoota> surprisingly not too many things get broken usually, so has actually been quite easy to follow up
<RX14>
crenv I don't recommend
<RX14>
I don't really have any better idea either - i ust use the arch package
<ua>
RX14, don't recommend why? here on ubuntu i've just installed and ran 5-6 versions in a row and worked great
<Yxhuvud>
in the longer term I'd want a port (or extension) of chruby - it is really small and does the least it can get away with.

<straight-shoota> I'm not sure how useful such a tool would be for Crystal...
<FromGitter>
<straight-shoota> you just need Crystal to build you application
<FromGitter>
<straight-shoota> not to run it like in an interpreted language
<FromGitter>
<Fryguy> it's useful if something worked in a previous version but not a new version
<FromGitter>
<Fryguy> you can switch back and forth really easily
<FromGitter>
<Fryguy> but as you said "surprisingly not too many things get broken usually, so has actually been quite easy to follow up"
<RX14>
ua, because for me it didn't work great
alex`` has joined #crystal-lang
<RX14>
it introduces bugs when working on crystal itself
<FromGitter>
<straight-shoota> yes but you don't necessarily need a tool for that. it can just be integrated into a build script
<FromGitter>
<straight-shoota> plus, it's less likely to have such a high diversity of language versions as with an interpreted lanugages
<RX14>
and I started writing a proper version manager for crystal
<RX14>
I just never got around to it
<FromGitter>
<marksiemers> Would it make sense to have `shards` handle crystal version management, in addition to shard version management?
<oprypin>
no
<oprypin>
at least there is 0 advantage to it
<RX14>
agree
<RX14>
do some thing and do it well
<RX14>
one*
<oprypin>
wel lactually for usage it could be nice, lik installing crystal version in shard.yml
<oprypin>
locally together with shards
<RX14>
it's easy to make a version tool parse version: foo in shard.yml
<RX14>
which was absolutely something I planned to do for my own tool
<oprypin>
just saying not literally 0 advantage
<RX14>
ok
<RX14>
lol
<RX14>
you could reuse the shatds.yml parser
<RX14>
cool

crystal/master bd42727 Johannes Müller: Reimplement Dir.glob (#5179)
<FromGitter>
<marksiemers> From a usage perspective, it likely means 2 commands to choose between - `shards ...` or `crystal ...` instead of 3 or more `crenv` or `anyenv` or `rx14env` or whatever version manager a certain team decided to use, or roll their own.
<FromGitter>
<marksiemers> It's like `Spec` being built into the language - since specs are pretty universal, why not have it baked in. ⏎ Version management is pretty universal as well I would argue.
