<FromDiscord> <Rika> other than one is stack one is heap?
<FromDiscord> <KnorrFG> id say thats a pretty relevant difference
<FromDiscord> <KnorrFG> ty
<FromDiscord> <Rika> well i dont know if you know that difference
<FromDiscord> <KnorrFG> but if the ref version is already on the heap. what is new used for then?

<FromDiscord> <carpal> In reply to @KnorrFG "but if the ref": maybe reallocate? idk
<FromDiscord> <Rika> new allocation
<FromDiscord> <Rika> no need to use if you use Type() notation though

<FromDiscord> <hamidb80> Error: closure in spawn environment is not allowed
<FromDiscord> <Rika> finalizers are being deprecated, use destructors (i forgot the link wait)
<FromDiscord> <Rika> https://nim-lang.org/docs/destructors.html
<FromDiscord> <Rika> not sure if this will fix the issue
<FromDiscord> <Rika> worth a try tho
<FromDiscord> <KnorrFG> ok, but doesnt that require --gc:arc?
<FromDiscord> <Rika> i believe not
<FromDiscord> <konsumlamm> are you using spawn (or threadpool) anywhere?
<FromDiscord> <hamidb80> In reply to @konsumlamm "are you using spawn": sent a code paste, see https://play.nim-lang.org/#ix=2QvR

<FromDiscord> <Rika> In reply to @hamidb80 "yes ```nim import": cant do that, vt has to be in getInput
<FromDiscord> <Rika> thats why the closure error
<FromDiscord> <hamidb80> In reply to @Rika "cant do that, vt": 👍
<FromDiscord> <hamidb80> i think with my Nodejs background it's gonna take time to adapt myself with nim
<FromDiscord> <konsumlamm> In reply to @hamidb80 "yes ```nim import": the error message is telling you exactly what's wrong there, you can't use a closure with spawn
<FromDiscord> <Rika> well they dont know what a closure is prolly
<FromDiscord> <Rika> or why getInput is a closure
<FromDiscord> <konsumlamm> a closure is a function that captures another variable (in this case vt)
<FromDiscord> <konsumlamm> (closures also exist in JS btw)
<FromDiscord> <Rika> theyre heavily used in js i believe
<FromDiscord> <hamidb80> In reply to @konsumlamm "(closures also exist in": i know but with js you can write every wired code
<FromDiscord> <Rika> even in node.js?
<FromDiscord> <hamidb80> In reply to @Rika "even in node.js?": yes
<FromDiscord> <Rika> as in for spawning threads
<FromDiscord> <hamidb80> (edit) "wired" => "wierd"
<FromDiscord> <Rika> and its not gonna break?
<FromDiscord> <hamidb80> In reply to @Rika "as in for spawning": i dont know about threading in nodejs
<FromDiscord> <Rika> spawn is threading

https://github.com/Araq/fosdem2020 doesn't compile with latest devel
From IRC (bridge bot)
@FromIRC
<FromDiscord> <Rika> thats why you cant use closures
<FromDiscord> <Rika> because it will lead to race conditions and such
<FromDiscord> <KnorrFG> sent a code paste, see https://play.nim-lang.org/#ix=2QvY
<FromDiscord> <konsumlamm> the reason is probably that threads must own the values they use (with the current default GC at least), so you can't reference variables that are possibly in another thread
<FromDiscord> <konsumlamm> In reply to @KnorrFG "if I try this:": you have to use it on the underlying object, yes
