17:48 <FromGitter> <erdnaxeli:cervoi.se> what is the best way to know if a type is `Int32?` ? (in a macro)

17:49 <FromGitter> <erdnaxeli:cervoi.se> I see there is `nilable?`

17:50 <FromGitter> <erdnaxeli:cervoi.se> or `union_types`, but that returns an array so it is ordered

17:56 <FromGitter> <Blacksmoke16> `.nilable?` would be the way to go

17:57 <FromGitter> <zomatree0:matrix.org> when inside a class function and i do ` if !@myattr.nil?` the compiler doesnt see this and throws an error because it could be `Nil`, is this an bug or something to do with race conditions? (note if i do `myvar = @myattr` then use it it works fine)

17:58 <FromGitter> <erdnaxeli:cervoi.se> @Blacksmoke16: but I want to know if it is exactly `Int32?`, not `Something?`

17:58 <FromGitter> <Blacksmoke16> @zomatree0:matrix.org thats expected, see https://crystal-lang.org/reference/syntax_and_semantics/if_var.html#limitations

17:58 <FromGitter> <zomatree0:matrix.org> ah i missed that, thanks

17:58 <FromGitter> <Blacksmoke16> @erdnaxeli:cervoi.se ahh hm

18:01 <FromGitter> <erdnaxeli:cervoi.se> so far I got `{% if ivar.type.union_types.size == 2 && ivar.type.union_types.includes?(String) && ivar.type.nilable? %}`

18:02 <FromGitter> <Blacksmoke16> did you try like `ivar.type == Int32?`?

18:02 <FromGitter> <erdnaxeli:cervoi.se> no, it works x)

18:02 <FromGitter> <erdnaxeli:cervoi.se> thanks

22:46 <FromGitter> <zomatree0:matrix.org> is there a way to use websockets while using fibers?, it seems the websocket is blocking the fibers

22:48 <straight-shoota> yes, that should definitely work

22:52 <FromGitter> <zomatree0:matrix.org> how? i can only find the .run method that seems to block everything

22:53 <straight-shoota> Yes. When you call that method in a fiber, all other fibers still run.

22:53 <straight-shoota> You just can't add code after that call.
