TIL :smile:

@Blacksmoke16

but if its just suggesting to install crystal apt, pretty sure those arent

at least via the official repo

hmm. i asked it again, to tell if afterwards that naqvis says this is wrong.

but now it answered:
Yes, it looks like you would need to build Crystal from source in order to use the interpreter. You can do this by cloning the Crystal repository and running the make command. Alternatively, you can try to find a pre-built package that includes interpreter support.

maybe it's reading this room hmm.

why is your answer different now from when i asked the first time?

I apologize if my previous response was incorrect. After researching the issue further, it looks like the pre-built Crystal package does not include interpreter support by default. In order to use the interpreter, you would need to build Crystal from source or find a pre-built package that includes interpreter support. My previous response may have been based on incorrect information or a misunderstanding of the question. Again, I apologize for any confusion or inconvenience this may have caused.

jfc...

that's pretty cool

how exactly did you research it further?
I researched the issue by looking at the Crystal documentation and other online resources, as well as checking the available pre-built packages for Crystal on Ubuntu. This allowed me to gain a better understanding of how the interpreter support is included in Crystal and what options are available for using it on Ubuntu.

but i'm not on ubuntu, i'm on windows!
If you are using Windows, you will not be able to use the pre-built Crystal package as it is only available for Linux-based systems. In order to use Crystal on Windows, you will need to build it from source by following the instructions on the Crystal website. Alternatively, you can try using a different package manager or pre-built package that is available for Windows. You can also try using a virtual machine or dual-booting to install a Linux-based operating system and use the pre-built Crystal package on that system.

ok i'll stop spamming now. but this thing is crazy 🤯

Hi! Is it possible to debug binaries with MT enabled? I'm trying to GDB into errors which I presume are caused by GC + GTK + MT, but running with gdb always fails. Current error message is SIGPWR, Power fail/restart, but I think I'have had others too. I am just generally wondering if it's possible to debug multithreading applications.

Tried with Valgrind?

no, though I barely even know what it is, I'll test that later. Thanks

<yxhuvud> sigpwr seems to happen on power failure. I hadn't seen that one before.

What am I defining the initial capacity for if I can't use it like this?
https://carc.in/#/r/e78e

George Dietrich

@Blacksmoke16

it allocates memory such that it could fit 100 Int32 values

azurelmao

@azurelmao

So in order to skip past indexes I first have to fill the array with some value?

George Dietrich

@Blacksmoke16

there's another overload that allows you to initialize each index to some value if you want

azurelmao

@azurelmao

Yeah ik, I had just hoped there would be a more convienent way to do it

George Dietrich

@Blacksmoke16

more convenient how?

or backing up, what end result are you wanting?

azurelmao

@azurelmao

It's just that I have a class which adds itself to a class var on init

def initialize(@id)
    if id > 0
      @@item_list.insert(@id, self)
    end
  end

so now I have to check whether the id is 0

in order to fill the array

George Dietrich

@Blacksmoke16

are they instantiated in order? i.e. is it possible the first instance has an @id of 10 and the next 1 or is it always going to go in order?

0, 1, 3, ...

0, 1, 2, ...*

azurelmao

@azurelmao

they won't be in order

George Dietrich

@Blacksmoke16

Hash(Int32, self).new then?

azurelmao

@azurelmao

Oh, I haven't thought of that

I'll try it

George Dietrich

@Blacksmoke16

seems like a more reasonable data model if you just want to store objects with a numerical key

azurelmao

@azurelmao

btw, this is unrelated to my previous question I'm just curious, but is there a literal for object instantiation? Something like:

foo = Foo{id: 1}

Which would bypass the initialize method and let you assign the properties by hand

George Dietrich

@Blacksmoke16

azurelmao

@azurelmao

I see

George Dietrich

@Blacksmoke16

unless you make everything nilable and do something like:

foo = Foo.new
foo.id = 1
...

but ofc, having a proper constructor is usually the better way

i.e. Foo.new 1 or Foo.new id: 1

azurelmao

@azurelmao

I usually avoid Nilable types, because of the trouble they cause

Anyways, thank you for helping me!

George Dietrich

@Blacksmoke16

actually, not exactly what you want, but you could look into https://crystal-lang.org/reference/1.6/syntax_and_semantics/literals/hash.html#hash-like-type-literal
