<S-YOU> Try with llvm5 `brew install llvm@5`?
<FromGitter>
<icyleaf> yeah, i was installed llvm@4, llvm@5, llvm6, and it was throwed error when uninstall llvm 6 (use llvm@5), it still not found x86_64. it happened since crystal 0.25.0.

<aisrael> @icyleaf Yeah I couldn't compile 0.25.0 on my Mac either, but had other things to do
<FromGitter>
<bcardiff> does `$ make clean deps` works?
<FromGitter>
<icyleaf> 👍 it works! thanks
<FromGitter>
<bcardiff> :-) changing the llvm in the middle left an unusable llvm_ext.o which is linked later.
<FromGitter>
<bcardiff> for succcesive compilation from a clean crystal compilatio of the compiler you can use `$ make clean_crystal crystal` that way the deps are not rebuilt, but you not use the compiled compiler to build a new compiler.
<FromGitter>
<bcardiff> I am not sure @faustinoaq but maybe the binary is not picking the expected openssl lib, I had used `--link-flags -L/usr/local/opt/openssl/lib` in some apps for that.
<FromGitter>
<faustinoaq> @bcardiff Oh ok, so should I create/replace the link manually?
<FromGitter>
<bcardiff> since you are installing an openssl from brew that might be the case.
<FromGitter>
<aisrael> What version of Crystal are you using?
<oprypin>
umutuluer, it's obviously some mismatch between the version of crystal (backwards incompatible change) and the version of the library (possibly not even updated yet)

<umutuluer> @aisrael ok, i will upgrade crystal and mysql package

<bcardiff> @umutuluer if you want to stay in 0.24.2 then you need to stay in crystal-mysql 0.4.0.

<bendietze_twitter> @icyleaf i mean, this would be crazy for test of cookies, sql, userdata ... Surely just must be done via fiber with some waittime.. But that should be possible... Is it possible to output raw response without parsing before?
<FromGitter>
<bendietze_twitter> I would need to things @icyleaf first is get the raw response (to be sure) and multipart/form-data including input multiple tag were nice :)
<FromGitter>
<bendietze_twitter> Wow! This is nice :) 👍
<FromGitter>
<faustinoaq> @bcardiff Yeah, I used that command and I got: `Unhandled exception: Invalid option: --link-flags (OptionParser::InvalidOption)` ⏎ ⏎ Can you reproduce this? 😅
<FromGitter>
<bendietze_twitter> @icyleaf i am not at home so not possible for me to check things out but nice to talk about :)
<FromGitter>
<bcardiff> @faustinoaq as a workaround if it does not work for you, you can build the specs with build and then run them.
<FromGitter>
<bendietze_twitter> @icyleaf maybe output is raw - i just have seen Halite possibilities - must try at home these days :)
<FromGitter>
<faustinoaq> @bcardiff Yeah, I'll try that, BTW, looks like `crystal spec` is using `setup_simple_compiler_options`, so, it doesn't support all flags 😅
<FromGitter>
<bendietze_twitter> @icyleaf next possibility could be easy running 1000 concurrent fibers with random data without many typing and such things - coool 😄
<FromGitter>
<bcardiff> @faustinoaq ooops . I guess the specs of the project I am mock the ssl connections.
<FromGitter>
<bendietze_twitter> @icyleaf and - as you done - cumulated test specs or fibers to run everything at least with one click - just for test after big changes - great :)
<FromGitter>
<bendietze_twitter> You could fork to HaliteX with capabilities for this 😄
<FromGitter>
<aisrael> Oooh... in `alpine:edge` you can just `apk add crystal` and get 0.25.0. Neat!
<FromGitter>
<icyleaf> @bendietze_twitter welcome any issues :) ⏎ @aisrael awesome!
<FromGitter>
<bendietze_twitter> I will go and check out these days :)
<FromGitter>
<bendietze_twitter> @icyleaf sorry, in your spawn snippet above Halite should be spawned as the server must completely be loaded, but, don't want to discuss about, nice you try it for me 👍 thx

<faustinoaq> @bcardiff `crystal run --link-flags -L/usr/local/opt/openssl/lib spec/amber_spec.cr` did the trick, thanks you! 😄 👍

<bendietze_twitter> btw... I got very service oriented and customer friendly response from bountysource, but since i started last month everything there is hanging. If i would not talk to them via email, i would drop every support because its extrem laggy and mostly no good experience to start sponsoring Crystal 😟 this system is irritating

<asterite> @MakeNowJust Lexer running on formatting is good. I just meant there's a lot of duplicate code. When I started implementing rufo ( https://github.com/ruby-formatter/rufo ) I did it more nicely, reusing a lot of code, extracting functions, thinking more clearly (I also had experience from Crystal's formatter). But, yeah, it's about doing it in the same way but without so much code duplication and little flags

<straight-shoota> @jokke `include` (and `included` macro) is evaluated before `JSON.mapping` is expanded.
<FromGitter>
<straight-shoota> you could probably work around that using `finished`, but it's probably better to just move to `@JSON::Field` annotation-based mappings available in 0.25.0.

duane has quit [Read error: Connection reset by peer]
<FromGitter>
<drum445> read up on the reflection docs but I can't see an equivalent to send in ruby or get_attr in python
<jokke>
@straight-shoota thanks!
<FromGitter>
<straight-shoota> @drum445 There aren't. Ruby and python are interpreted, but Crystal is compiled and doesn't have the required information available at runtime to do arbitrary method calls.
<FromGitter>
<drum445> It's not a method call it's an attribute getter by name
<jokke>
oooh thats very nice!
<FromGitter>
<drum445> Go allows this with it's reflection package
<FromGitter>
<straight-shoota> jokke, the main reason for this is to solve exactly such problems depending on order of execution as you've encountered. And it makes JSON properties easily expandable in subclasses.

snsei has joined #crystal-lang
<FromGitter>
<asterite> Basically, there's no way to do what you want. Or maybe yes, you could always have `def initialize(**args)` and then inside that method traverse the instance vars... but I think it won't work.
<FromGitter>
<asterite> And I don't think mass assignment is something good
<FromGitter>
<asterite> I think Crystal should implement runtime reflection and drop compile-time reflection. Maybe also drop nil detection and go for the usual "null pointer exception". It will make the language both simpler and more powerful (null pointer exception is really not that terrible). But I don't know how would all of that look like in Crystal...

<asterite> I mean it. Runtime reflection is superior to compile-time reflection. Right now for every type you get a loooot of duplicated code to parse/serialize it from/to JSON. With runtime reflection it's just one method. Maybe a bit slower, but not significantly slower (or, people don't really care about that kind of performance when you put together a lot more things into your program). And then because values don't
<FromGitter>
... have a default value (zero for numbers, null for references) you can't instantiate instances generically. Well, you can, but then you would get horrible segfaults. So someone really has to prove the merits of compile-time reflection and strong nullability check.
