02:11 <FromGitter> <Blacksmoke16> if using property macro is no way to have the doc comment message be different for getter/setter right?

02:15 <FromGitter> <Blacksmoke16> on another note

02:15 <FromGitter> <Blacksmoke16> https://play.crystal-lang.org/#/r/4kms this could prob have a better error message

02:15 <FromGitter> <Blacksmoke16> line number/variable name maybe?

03:06 <FromGitter> <bew> @Blacksmoke16 good idea!

03:06 <FromGitter> <bew> @RX14 awesome PR! Why is the personality fun `_CxxThrowException` though?

07:03 <FromGitter> <straight-shoota> @soanvig The existing JS didn't follow any conventions, so I didn't bother

09:39 <RX14> @bew because thats the personality for C++-style exceptions on windows

09:39 <RX14> its just how it works

09:40 <RX14> windows provides that function

09:40 <RX14> also it's __CxxFrameHandler3 for the personality not _CxxThrowException

10:16 <FromGitter> <godmode97> have you ever encountered this error?

10:59 <FromGitter> <straight-shoota> If someone want's to get started working on the Compiler, #6417 could be a great feature for beginners. =)

11:24 <Groogy> Is faustino online?

11:25 <Groogy> I'm getting wonky syntax highlighting with divider and regexp :/

11:33 <literal> when parsing JSON with from_json I seem to get strings that are double-encoded, any tips? https://gist.github.com/hinrik/af9603ec514175cd3418999066bcc0e8

11:34 <literal> the JSON file uses \uXXXX in its strings for non-ASCII

11:36 <literal> and e.g. when I do "puts msg.sender_name" it gives me "Ãrn" instead of "Örn"

11:46 <literal> pp JSON.parse %{["\u00c3\u0096rn"]} # prints garbage

14:30 <FromGitter> <j8r> How can I split simply an array in two parts a `x` index? something like `array1, array2 = old_array.split(x)`

14:31 <FromGitter> <j8r> for now I use `array1 = old_array[0...x]; array2 = old_array[x..-1]` :/

14:32 <Groogy> partition maybe?

14:33 <Groogy> but yeah that works, you don't need two assignments though

14:34 <Groogy> array1, array2 = old_array[0...x], old_array[x..-1]`

14:34 <Groogy> should work I think?

14:34 <FromGitter> <bew> Our use `...split(x, limit: 2)`

14:34 <FromGitter> <bew> Or*

14:35 <Groogy> where's split defined?

14:36 <Groogy> I can only find split being defined in String

14:37 <FromGitter> <bew> Ah true

14:42 <FromGitter> <j8r> there is a difference between `array1, array2 = old_array[0...x], old_array[x..-1]` and `array1 = old_array[0...x]; array2 = old_array[x..-1]` ?

14:43 <Groogy> no, just it becomes a one liner :P

15:18 <FromGitter> <jspillers> my program is intermittently terminating and simply dumping `gmp: overflow in mpz type` to the terminal with no backtrace or any clue as to where the failure occurred. I am pretty sure the issue is with a BigDecimal calculation (GMP is used for all the classes in "big" I believe), but no idea how to debug when there is no backtrace. Any recommendations on how to approach?

15:21 <FromGitter> <j8r> @jspillers how much memory takes your application?

15:21 <FromGitter> <jspillers> let me see...

15:22 <FromGitter> <j8r> maybe you have somewhere a "big" operation, and this go beyond the memory limit of a crystal program

15:22 <FromGitter> <jspillers> 1) 594768 mb according to `ps`

15:23 <FromGitter> <jspillers> @j8r ^

15:24 <Groogy> eh what

15:25 <Groogy> are you sure that's mb?

15:25 <Groogy> because that would be 600gb

15:25 <FromGitter> <jspillers> you are missing the `.` in there

15:25 <FromGitter> <jspillers> its 4.5 mb

15:25 <Groogy> I don't see a single dot

15:25 <FromGitter> <jspillers> must be lost in gitter -> irc translation

15:27 <FromGitter> <j8r> Julian has the same problem https://github.com/JuliaLang/julia/issues/8286

15:27 <FromGitter> <j8r> no fix yet

15:28 <FromGitter> <j8r> or only partial, with links to explanations

15:28 <FromGitter> <jspillers> oh yeah that is the exact error i am dealing with

15:29 <FromGitter> <jspillers> i don't *really* need the precision of BigDecimal... maybe ill just switch to Float64

15:29 <FromGitter> <j8r> the difference is the stack trace, there is none in Crystal (not normal)

15:30 <FromGitter> <j8r> you do mathematical operations?

15:32 <FromGitter> <jspillers> im not doing anything crazy... just normal arithmetic on fairly tiny decimals

15:33 <FromGitter> <jspillers> calculating technical analysis indicator values

15:39 <FromGitter> <j8r> so yes you can use float32

15:39 <FromGitter> <j8r> or if you prefer float64

15:39 <FromGitter> <jspillers> yeah float32 should be plenty of precision id guess

15:41 <FromGitter> <jspillers> interesting that the type inference defaults to Float64 when you do something like `blah = 1.2345`

16:18 <Yxhuvud> groogy: it is only defined on String. What do you want to split that isn't one?

16:18 <Groogy> no wasn't me

16:19 <Groogy> was j8r

16:21 <oprypin> Yxhuvud, Groogy, how about that meetup

16:22 <Groogy> Huh? have I missed something?

16:22 <Groogy> I would love a crystal meetup

16:23 <oprypin> Groogy, there's no meetup, i mean we could do an informal one in stockholm

16:23 <Groogy> that would be cool, I'm game for that

16:25 <Groogy> as long as the place has AC haha

16:25 <oprypin> lol

16:25 <Groogy> god my appartment was built to keep heat in, not out

16:29 <Groogy> Where would work for you guys? I work at södermalm but I can reach anywhere of course

16:37 <Yxhuvud> I work and live on södermalm, but I have vacation so I can basically reach anywhere. I'll be out of town during weekends for a long while though

16:37 <Yxhuvud> but outside weekends, I'd love to meet up

16:40 <oprypin> weekdays are fine by me, almost any time or place

16:40 <Groogy> yeah weekdays are preferable since I live outside of södermalm and I don't have vacation yet

20:49 <FromGitter> <jspillers> Anyone know of any NYC crystal meetups? Is anyone else even in NYC here? :)

23:55 <FromGitter> <zbaylin> Does anyone know of a datetime string format with Timezone which Crystal accepts?

23:56 <FromGitter> <zbaylin> I have tried a bunch but all of them trigger this error `Time format did not include time zone and no default location provided`
