00:45 <oprypin> Blacksmoke16: what are you doing, basically telling girng to shoot himself in the foot

00:46 <oprypin> you gotta use sudo and you gotta like it

00:46 <FromGitter> <Blacksmoke16> ;)

00:47 <FromGitter> <Blacksmoke16> with great power comes great responsibility

00:48 <oprypin> https://youtu.be/6bsNIdYw5Ak

00:56 <FromGitter> <girng> i'm lost

00:59 <FromGitter> <girng> he likes arch linux i get it

01:31 <FromGitter> <girng> https://forum.crystal-lang.org/t/whats-your-favourite-recommended-linux-distro/261

01:32 <FromGitter> <Willyboar> lol. I told you to test elementary

01:32 <FromGitter> <Willyboar> i use it in old amd laptop w/ 4 gb ram and HDD

01:32 <FromGitter> <Willyboar> and is running smoothly

01:33 <FromGitter> <Willyboar> @girng 🆙

01:33 <FromGitter> <Blacksmoke16> iirc Alpine is only one you can staticly build on, so if you getting it for crystal, that would prob be bets?

02:00 <FromGitter> <girng> @Willyboar lol yeah. i will prob use that but just wanted to get some activity going on the forum too

04:04 <FromGitter> <Blacksmoke16> @vladfaust Prob not a bad idea, my site for another side project is using it atm. But its only 1 endpoint so not much to go off of ha

04:34 <FromGitter> <Blacksmoke16> https://github.com/Blacksmoke16/CrSerializer/releases/tag/0.5.1 small release for some little things

04:53 <FromGitter> <DanilaFe> definitely do not stay root. sudo is a big part of the process, and it lets you know that you may potentially be running destructive actions

04:54 <FromGitter> <DanilaFe> I think there are a few arch-based distros that don't force manual install, like manjaro and antegros (?)

04:54 <FromGitter> <Blacksmoke16> https://github.com/Blacksmoke16/athena/releases/tag/v0.1.0 initial release 💯 feedback/issues are welcome :)

06:22 <FromGitter> <spTorin> Ubuntu based distro and some other not have root user (and its good). Not need su command with root password. Just use `sudo -i` and own password.

06:50 <FromGitter> <DanilaFe> Please help :( ⏎ I have the following (abridged) code: ⏎ ⏎ ```no overload matches 'Int64#>' with type (Int64 | Nil)``` [https://gitter.im/crystal-lang/crystal?at=5c32f6c326d86e4d563a244c]

06:56 <FromGitter> <DanilaFe> disregard the fact that I used id instead of @ id, causing infinite recursion. this does not fix the issue

07:03 <oprypin> Blacksmoke16: we were trying to get girng to try Linux for the first time but i think you are trying to make it the last

07:03 <oprypin> re: Alpine

08:37 <FromGitter> <rishavs> Are there any email servers in crystal? I want to implement a "Forgot Password" feature and was wondering how to go about it?

08:45 <FromGitter> <spTorin> @rishavs - try https://github.com/arcage/crystal-email

08:46 <FromGitter> <rishavs> Thanks

09:10 <FromGitter> <nagash> @DanilaFe The problem is your setter type `Int64?`

09:18 <FromGitter> <nagash> @DanilaFe Actually that's not right. I suspect the problem lies in whatever other type of object could be in the `item.body` Enumerable. ⏎ You could fix it with `item.body.select(&.is_a?(Terminal)).map(&.as(Terminal)).max_of?(&.id) || 0_i64`, or you can fix the other `item.body` objects `id` property to not be `(Int64 | Nil)`

12:46 <FromGitter> <girng> good morning!!

12:46 <FromGitter> <bew> Good afternoon!!

12:47 <FromGitter> <girng> 😆

12:49 <FromGitter> <bew> @DanilaFe you can simplify the `id` method's code by doing: `def id; @id || raise_general "...", internal: true; end`

16:01 <FromGitter> <girng> https://play.crystal-lang.org/#/r/5xxj is doing `.clear` more performant?

16:07 <FromGitter> <Blacksmoke16> ``````

16:07 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5c33793f8b6399655e208854]

16:07 <FromGitter> <Blacksmoke16> looks like it

16:07 <FromGitter> <Blacksmoke16> @girng

16:08 <FromGitter> <girng> oh wow lol, thanks. i just saw some i had the assign in my clear block list method 😆

16:09 <FromGitter> <girng> i was thinking to myself.. that doesn't seem right!

16:10 <FromGitter> <kinxer> @Blacksmoke16 Does that code re-initialize `blocked_users` or is it just empty after the first clear?

16:10 <FromGitter> <vlazar> +1

16:10 <FromGitter> <vlazar> careful with what you measure

16:11 <FromGitter> <Blacksmoke16> :0 goo call

16:13 <FromGitter> <kinxer> I got this: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5c337a8c357dd7655d2fc4a3]

16:13 <FromGitter> <Blacksmoke16> looks like clear of 50% faster

16:13 <FromGitter> <Blacksmoke16> proven with science and multiple supporting evidence :p

16:13 <FromGitter> <kinxer> ^

16:13 <FromGitter> <kinxer> :P

16:15 <FromGitter> <girng> thx

16:19 <FromGitter> <girng> i love how the db module lets you interact with db queries in a synchronous manner. but i mean, to be fair if i was still on nodejs i'd prob be using async/await.. but still, that wasn't around back when i was using node, and not going back now. that i can tell you

16:22 <devil_tux> can someone jump in here before I start to cry, having troubles with regex: https://play.crystal-lang.org/#/r/5xz4

16:24 <FromGitter> <Blacksmoke16> https://play.crystal-lang.org/#/r/5xz7

16:24 <FromGitter> <Blacksmoke16> `\b` gets escaped to `b`

16:24 <FromGitter> <Blacksmoke16> so have to double escape the backslash since you want it to actually be in the string

16:25 <FromGitter> <Blacksmoke16> https://crystal-lang.org/reference/syntax_and_semantics/literals/string.html#escaping

16:25 <devil_tux> Blacksmoke16: it's always you. Thank you <3. I lost my mind over it for couple of hours.

16:25 <FromGitter> <Blacksmoke16> `Any other character following a backslash is interpreted as the character itself.`

16:25 <FromGitter> <Blacksmoke16> np

16:25 <devil_tux> didn't know it plays a role in regex but makes sense

16:26 <FromGitter> <Blacksmoke16> be nice if there was some literal that didnt do that

16:26 <FromGitter> <Blacksmoke16> for this very reason

16:26 <FromGitter> <Blacksmoke16> but, not a big deal

16:28 <devil_tux> gotcha, appreciated

16:45 <FromGitter> <girng> blacksmoke the hero we deserve

17:29 <FromGitter> <DanilaFe> Thanks @bew. For the record, the problem was a JSON.mapping call that produces an Int64? getter

17:41 <oprypin> Blacksmoke16, devil_tux, check out `%q(` literal. and for this case verbose regex `/stuff/x`

17:42 <FromGitter> <Blacksmoke16> ah nice one

17:43 <oprypin> https://crystal-lang.org/reference/syntax_and_semantics/literals/regex.html#modifiers it can be multiline and ignores whitespace

20:40 <rkeene> I'm trying to compile the code: `dbconfig = INI.parse(dbconfig_text)` in Crystal 0.27.0 and I get the error: `undefined constant INI (did you mean 'Int')`

20:41 <FromGitter> <Willyboar> WOW! Github offers unlimited private repos. For 3 collabs per private repo. Bye bye bitbucket.

20:41 <rkeene> The documentation doesn't suggest one needs to "require" anything first, but I wonder if that's an omission from the documentation

20:42 <rkeene> Adding `require "ini"` did seem to help

21:01 <FromGitter> <straight-shoota> rkeene, yeah it's not always clear from the API docs which libraries are in core (implicitly required in the prelude) and which need to be explicitly asked for

21:20 <FromGitter> <domgetter> I'm trying to C interop to do opengl programming with crystal on windows. I can get 3D stuff to appear on linux (using opengl, glew, and sdl2), but I'm running into a problem where I need to link to stuff at runtime. I can use this https://docs.microsoft.com/en-us/windows/desktop/api/wingdi/nf-wingdi-wglgetprocaddress , and it works (i.e. compiles on windows) if I only use one type signature for the

21:20 <FromGitter> ... returned function pointer. If I try to generalize, with something like Pointer(Int32 | UInt32, (UInt32 | UInt8)* -> Int32) or anything else, crystal complains that "only primitive types, pointers, structs, unions, enums and tuples are allowed in lib declarations", and if I try with underscores, I'm met with "can't use underscore ... [https://gitter.im/crystal-lang/crystal?at=5c33c28c5ec8fe5a85194172]

21:21 <FromGitter> <eliasjpr> Where I can find docs in regards to JSON annotations?

21:21 <FromGitter> <eliasjpr> nvm

21:28 <FromGitter> <j8r> @domgetter note Windows support is WIP (excluding WSL, which is =~ linux)

21:28 <FromGitter> <domgetter> @j8r Noted, and I am compiling on WSL and then hopping over to link on Windows.

21:31 <FromGitter> <domgetter> I can get sdl2 functions and some gl functions to link, but other ones don't want to work at all, like glGetUniformLocation. I even tried linking through glew, but it didn't work even though glew32s.lib contains the function name if I grep through it. So I have no idea what I'm doing wrong, or perhaps if there was some Windows-specific issue. I figured I may have to get function pointers at run time, but I

21:31 <FromGitter> ... didn't know if there was a clean way to do that in Crystal.

21:49 <FromGitter> <j8r> do you know you can even run X server on WSL?

21:50 <FromGitter> <j8r> (a bit offtopic)

21:52 <FromGitter> <domgetter> I hadn't tried to. Since I successfully got a window up from a cross compiled app, I was going to go 100% down this path

21:52 <FromGitter> <j8r> sure

21:52 <FromGitter> <j8r> that's the proper path

22:11 <FromGitter> <wontruefree> Is there a way to call a ruby api from crystal?

22:11 <FromGitter> <vladfaust> Kek, got 100k jobs per second for background job processing (2 Crystal threads with `Process.fork`): https://snag.gy/KWBC92.jpg

22:13 <FromGitter> <vladfaust> This was with 10_000 fibers & 10 Redis clients per thread

22:17 <FromGitter> <vladfaust> Aaand I got 130k with 100k fibers

22:27 <FromGitter> <theretromaniac> From now on i will use this account 😄 (@Willyboar)

23:00 <rkeene> Does Crystal handle a signed integer overflow by throwing an exception ?

23:08 <rkeene> http://chiselapp.com/user/rkeene/repository/flint/artifact?udc=1&ln=81-83%2086&name=fa2ac06db0ef7c22 is what I'm doing now -- but I'm not sure it's actually meaningful

23:22 <FromGitter> <straight-shoota> rkeene, integer overflow is not yet available, but it's actively being implemented

23:24 <rkeene> With Crystal type promotion, will that check be comparing an Int32 and a UInt32 ?

23:27 <FromGitter> <wontruefree> @straight-shoota how do you like fossil I tried it back in the day but my team wanted to use github

23:28 <FromGitter> <straight-shoota> rkeene, what check?

23:29 <FromGitter> <straight-shoota> @wontruefree Why do you ask? ;) I've never used fossil. And wouldn't consider it, given that basically everyone is on git and it's not like totally different.

23:46 <FromGitter> <domgetter> Am I crazy or is there very clearly an overload that matches? https://gist.github.com/domgetter/3506aab2246168890b5522a7c900a20c

23:47 <FromGitter> <domgetter> Ohh, I can't do chars AND a block
