12:57 <FromGitter> <Blacksmoke16> o/

14:56 <FromGitter> <RespiteSage> Is there an easy way to determine if a `File` is at end-of-file?

14:57 <FromGitter> <Blacksmoke16> `file.peek.try &.empty?`?

14:58 <FromGitter> <RespiteSage> I'm deserializing a binary file that has a header and an unknown number of records (it's gridded, but some points may be missing).

14:58 <FromGitter> <RespiteSage> Yeah, that's probably the way to go. It's just weird that there's nothing clearer.

14:58 <FromGitter> <Blacksmoke16> or do something with `.pos`

14:58 <FromGitter> <Blacksmoke16> like if `file.pos == size_of_file` or something like that?

15:00 <FromGitter> <RespiteSage> Yeah, that was the other thing I was thinking. I think I'll go with the first one in case we ever decide on a way to send this data over a network (though we'll of course have to wrap it in something that can receive information about whether it's received everything).

15:02 <FromGitter> <RespiteSage> I'm checking issues to see if there's a reason why we don't have `File#eof?`.

15:05 <FromGitter> <RespiteSage> https://github.com/crystal-lang/crystal/pull/6873

15:06 <FromGitter> <RespiteSage> It seems like the answer is basically "it's inconsistent due to race conditions"

15:07 <FromGitter> <RespiteSage> @Blacksmoke16 Thanks for labelling it. :)

15:08 <FromGitter> <Blacksmoke16> 👍

15:31 <raph_ael> is there a working shell in crystal, like xonsh in python, that can help trying it on daily basis and scripting ? thanks

15:33 <FromGitter> <Blacksmoke16> https://crystal-lang.org/2021/12/29/crystal-i.html would prob be your best bet

17:11 <FromGitter> <RespiteSage> Is there a better way to get a `Slice(T)` from an `Array(T)` than `arr.to_unsafe.to_slice(arr.size)`?

17:16 <riza> not that i've found

17:17 <FromGitter> <RespiteSage> Good to know. Thanks!

19:41 <FromGitter> <RespiteSage> You can't do `typeof(non_constant_variable)` at compile-time, right?

20:54 <FromGitter> <Blacksmoke16> like in a macro?

21:53 <FromGitter> <RespiteSage> Yeah, that's what I was thinking. But I thought that macros are evaluated too early.

22:26 <FromGitter> <Blacksmoke16> Either way, typeof doesn't work in macros

23:14 <FromGitter> <RespiteSage> Gotcha. Thanks!
