01:40 <FromGitter> <georgeu2000> Wow Gary Bernhardt, long time no hear!

01:40 <FromGitter> <georgeu2000> I loved DAS, so many years ago...

02:00 <FromGitter> <ino76> hi :) is there some way to compile crystal from linux to windows?

04:24 <FromGitter> <fridgerator> no

06:46 <Groogy> Morning! o/

06:51 <FromGitter> <ekremkaraca> Morning guys

07:14 <Groogy> gonna see if I can get free type to cooperate today

07:14 <Groogy> *sigh*

08:17 <FromGitter> <ekremkaraca> Hey guys, is it possible to access instance variable defined in a class from outside?

08:22 <Groogy> only through a method call

08:22 <FromGitter> <sdogruyol> Morning everyone

08:22 <Groogy> Morning sdogruyol o/

08:23 <FromGitter> <sdogruyol> sup @Groogy

09:20 <FromGitter> <ekremkaraca> I supposed so but

09:22 <FromGitter> <ekremkaraca> When I define a class, then call it and assign its instance to a variable, then I call its instance variable, it returns its value.

09:23 <FromGitter> <ekremkaraca> For example, I defined a person class with @age variable inside it

09:23 <FromGitter> <ekremkaraca> Then I called person = Person.new

09:23 <FromGitter> <ekremkaraca> Then I hit person.@age

09:24 <FromGitter> <ekremkaraca> But I got its value instead of an error like Ruby

09:25 <FromGitter> <ekremkaraca> Sorry, unlike ruby

09:30 <Groogy> huh sounds like a bug

09:31 <Groogy> https://play.crystal-lang.org/#/r/2s1t

09:31 <Groogy> that's freaky

10:36 <oprypin> Groogy, nah it's not a bug, it's Tricks They Don't Want You to Know

10:36 <Groogy> lol

10:37 <oprypin> seriously though it's intentional but likely pending removal

10:41 <oprypin> then again, https://bpaste.net/show/75db98f773c7

10:55 <Groogy> I mean I don't mind friends as much, at least friends over this kind of public access

10:56 <Groogy> (not friends as in C++ style but how D does it with sub classes that have access which will give you indirect access to things you want to keep normally hidden)

11:06 <oprypin> yes, Crystal needs friends........

11:07 <oprypin> the closest thing is https://crystal-lang.org/docs/syntax_and_semantics/visibility.html#protected-methods but otherwise severely lacking

11:21 <Groogy> Yeah would be cool if Crystal could have something akin to packages

11:21 <Groogy> as in D

11:21 <Groogy> though maybe more you declare a package and classes can claim to belong to it and it is another scope of visibility

12:14 <vegai> does it make sense to just cast Ints from C bindings to Int64 instead of doing the awkwardish LibC::Int?

12:14 <vegai> at least when resources aren't an issue

12:21 <FromGitter> <ziprandom> @krypton97 yeah. when I use the lib in my own crystal script it works, just the curl snippet didn't do anything although it compiles without error

12:31 <Groogy> how do I define a default value using a block with hashes?

12:31 <Groogy> been trying but keeps getting key error

12:33 <Groogy> @pages = Hash(UInt64, Page).new { Page.new @face, @gfx }; @pages.fetch(12u32)

12:33 <Groogy> gives me key error :/

12:34 <Groogy> oh wait I am dumb nvm

14:01 <FromGitter> <krypton97> Any workaround for binding :: on a useless key on vscode?

14:29 <Groogy> aaaaalmost there....

14:32 <Groogy> something maps wrong when it tries to read the pixels

14:34 <FromGitter> <ansarizafar> How can we check that body exists and not nil ⏎ ⏎ ``` context.request.body``` [https://gitter.im/crystal-lang/crystal?at=59c670e2bc46472974697e5b]

14:54 <Groogy> GAH WHY IS IT READING THE PIXELS WRONG ;_;

14:54 <Groogy> (ﾉ `Д´)ﾉ ~┻━┻

14:57 <FromGitter> <ziprandom> hey what is the best tool to profile a crystal application on linux?

14:57 <Groogy> you could use the Benchmark module in crystal

14:59 <FromGitter> <ziprandom> yeah but thats cumbersome. I want something to show me in which methods it spends the most time without having to wrap everything in benchmarks

15:00 <Groogy> gprof maybe?

15:00 <Groogy> I mean it is a binary like any other so anything that works on C++/C should work here as well

15:00 <Groogy> not 100% sure though

15:06 <FromGitter> <ziprandom> thxx Groogy, trying with oprof now, let's see

15:18 <crystal-gh> [crystal] asterite opened pull request #5024: [WIP] Int128 and UInt128 (master...feature/128-bit-integers) https://git.io/vdUGm

16:05 <crystal-gh> [crystal] asterite opened pull request #5025: Compiler: use return type of method with Primitive if available (master...refactor/simplify-primitivs) https://git.io/vdUct

16:36 <Groogy> When I print it manually to the console, letter looks just fine

16:36 <Groogy> when I print it to screen it gets distorted :/

16:36 <oprypin> vegai, it's a very good idea to never expose the C types in your public API. for the case of `LibC::Int` in particular, what I like to do is use Int in lib bindings and then, without casting, specifying the return type Int32

16:59 <Groogy> YES I SOLVED IT ;_;

16:59 <Groogy> I can load a font into texture memory

17:00 <Groogy> now just need to clean things up and implement a way to efficently render text

17:02 <FromGitter> <bararchy> Cool Groogy !

17:02 <Groogy> been smashing my head into it for weeks it feels like

17:03 <oprypin> why tho

17:03 <oprypin> i could appreciate that if it was something done for the first time

17:03 <Groogy> because I had forgotten to set the unpack alignment of pixels when uploading the pixels to the texture

17:04 <Groogy> i.e sincei t was 8bit bitmap it was not divisable by four

17:04 <Groogy> and it would sometimes screw everything up depending on size of bitmap

17:04 <Groogy> now my texture sets the unpack alignment correctly before uploading the pixels

17:05 <Groogy> most embarrising part is that it is even under "common mistakes" on khronos wikipedia

17:05 <Groogy> https://www.khronos.org/opengl/wiki/Common_Mistakes#Texture_upload_and_pixel_reads

17:08 <Groogy> the result! https://imgur.com/a/jglzo

17:16 <FromGitter> <bararchy> Groogy , super cool ! most of the times, it's the little things that screw things up XD

17:37 <FromGitter> <aaronbronow> is there a document that explains how to build and run the docker image for development?

17:38 <FromGitter> <aaronbronow> i've pulled it but i don't know how to actually run it

18:38 <FromGitter> <samueleaton> @aaronbronow so you need a dockerfile in your application and then you just need to build your app image and run it. The thing is that you would need to remove and re-build your image on every change so you can use sentry.cr in your dockerfile so it watches and recompiles on any change without the docker container needing to restart. ⏎ ⏎ here is an example dockerfile and command to build your app:

18:38 <FromGitter> ... https://gist.github.com/samueleaton/d112ab5cfac7b707fdd2b1e4ec110d43

18:40 <FromGitter> <samueleaton> But in dev you can also use docker-compose and a docker-compose.yml which is another level of abstraction on top of your dockerfile

18:43 <FromGitter> <samueleaton> To clarify, you don't run the crystal image directly, but instead you base your app's dockerfile on the crystal image.

21:34 <FromGitter> <Fanna1119> has anyone ever ran into an error similar to this ⏎ "this version of PCRE is compiled without UTF support at 0 (ArgumentError)" ?

21:49 <oprypin> Fanna1119, yeah probably

21:51 <FromGitter> <bew> Groogy congrat!

21:59 <FromGitter> <Fanna1119> took me a while to figure it out. had to find my PCRE version , using pcretest -C , find the package and ./configure --enable-utf8 --enable-unicode-properties, and then make the package, :D well with every hiccup you learn something new i guess haha

22:59 <FromGitter> <akzhan> @Fanna1119 see https://github.com/crystal-lang/crystal/pull/4712 for example

23:40 <Groogy> Thanks @bew!
