Yeah I was wondering if return "foo" would make a return in the method I declare the Proc or if it does a return in the Proc
<Groogy>
since you also have break "foo"
<Groogy>
for blocks
<FromGitter>
<girng> whats the diff between proc and a method?

from my understanding: procs are objects, methods are syntax-level constructs

I *think* Procs are closures which can encapsulate data from the context they were written in, and realised as objects with a call method. So a = 12; some_func(->(x) { a * 32 }) will create something like (in pseudocode) object { @a = 12; call(x): @a * x }. But the @a value won't actually be copied, it'll be a reference to the real a.

<diegogub_gitlab> hi guys, I keep having issues with DNS into docker and crystal. I saw all the github issues, and seems to be resolved..but still I can't make it work. Someone has any idea how could I do a work around? Docker is running in host network mode.
<FromGitter>
<diegogub_gitlab> trying out with other languages and same configuration seem to work
<FromGitter>
<talbergs> do you know about `docker.for.mac.localhost`?
<FromGitter>
<diegogub_gitlab> @talbergs no, sorry. what's that? I'm running on linux
<FromGitter>
<talbergs> nvm, that is an answer to most of problems relating DNS if you on OSX.

<yxhuvud> yaml is not necessarily transferable to legal json.
<FromGitter>
<yxhuvud> json on the other hand doesn't need to be converted - it is already legal yaml.

<j8r> How can I convert a JSON::Any to Yaml?
alex`` has joined #crystal-lang
<jokke>
Yxhuvud: sure, but shouldn't at least Hash(String, JSON::Any).from_yaml work?
<jokke>
it seems hash doesn't implement from_yaml
<jokke>
which is weird to me
<jokke>
never mind
<jokke>
of course it does
<jokke>
wait what..? recursive aliases aren't possible anymore?
<jokke>
no i'm just dum

<FromGitter>
<talbergs> Uff, @vladfaust I found that my shard will not work (as I stated above) because of hyphen in it's name, changed `name: crystal-dgraph` into `name: dgraph` and I could `require "dgraph"`, but not `require "crystal-dgraph"` seems like #bug ?
<jokke>
hm so there's no way of parsing yaml into a json conform data structure?
<FromGitter>
<vladfaust> @talbergs never had such an issue, maybe you've done something wrong like mispelled shard name in either shard.yml

raze is more minimalist than kemal, but you may consider that its just not as far into development. its mostly focused around the way it handles middleware

does anyone know of a way to provide a dsl to set instance vars of an object where not all if any instance vars are nilable?
<jokke>
i already discovered that double splat initializers can be used for mass assigning the instance vars
<jokke>
but i'm not sure how a dsl would look like without having to write it completely manually
<jokke>
oh and this should be completely type safe too and checked at compile time too :D

<ninetailschris> How can I convert Array(JSON::Any) into a regular array?
<FromGitter>
<asterite> it depends... what do you have in the `JSON::Any`?
gtramontina has joined #crystal-lang
<FromGitter>
<ninetailschris> its just nested arrays with intergers and strings inside an array example being [[127, [12, 24, 22, 13, 14, 18], [0, 252, 0, 0, 0, 0, 0], 100, 2352, 13, 1, 0, false, "Cow", 0]]

<bew> false in your data is not a string or an integer

wu... instance variable '@schemas' of OpenAPI::Components must be (Hash(Symbol, OpenAPI::Reference | OpenAPI::Schema) | Nil), not Hash(Symbol, OpenAPI::Schema)
<jokke>
*wut
<FromGitter>
<ninetailschris> Forgot to add bool. Sorry about that
<jokke>
how is Hash(Symbol, OpenAPI::Schema) not a part of (Hash(Symbol, OpenAPI::Reference | OpenAPI::Schema) | Nil)?
<jokke>
z64: take a look at prism
<jokke>
early stages but really cool

especially the param handling

yeah i've been meaning to. writing the frontend component for my project soon, so i plan to start re-evaluating what my webserver needs will be

<girng> @atna ty for explanation same for @woodruffw. i'm going to just stick to methods for now until i need to use procs

<paulcsmith> Yay for 0.26.1! Thanks for the new release Crystal team :D
<FromGitter>
<paulcsmith> Homebrew having a release at the same time is an extra nice surprise 👍

<eliasjpr> Interesting presentation about Scala compiler

<girng> @rishavs which ones?
<FromGitter>
<girng> @rishavs if they don't u can use pm2 and basically make nodejs run on multiple cores.and use redis for pub sub thjat's what i use to do
<FromGitter>
<girng> now that I think of it, we can do the same with crystal since their redis shard is epic

<rishavs> fastify.io mainly. I am torn between fastify and crystal based REST api. my deployment plan is to use a single processor doker container and then conjure up as many instances of the server as I need to.
<FromGitter>
<rishavs> And fastify compares well wit crystal in terms of single processor speed.
ua has joined #crystal-lang
<FromGitter>
<vlazar> @rishavs are you comparing some real REST API endpoint in Crystal/fastify or is it just a hello world benchmark?
<FromGitter>
<rishavs> I am looking to decide on a lang/framework for my next toy project. It is to be a spa with a rest api based backend. so, no code so far.
<FromGitter>
<rishavs> itching to give elm 0.19 a try
<FromGitter>
<vlazar> TFB results provide at least some idea of what to expect in different scenarious
<FromGitter>
<vlazar> for example Crystal performs very well in JSON benchmark
<FromGitter>
<vlazar> for DB the results are not that excited, but it's a good idea to benchmark you specific use case, not some generic
<FromGitter>
<rishavs> yep

<bcardiff> that or running apt-get install in the Dockerfile. it depends in your dev env
<FromGitter>
<diegogub_gitlab> @bcardiff I see.. I will try, the issue I think is that openssl can't find the certs on the docker scratch, because I tried to turn off validation and works for https..gracias!

<bcardiff> Try to make a small sample of what you are trying to do so you can share some code. De nada!
