02:09 <FromGitter> <renich> I am getting: Expected MAPPING_START but was SCALAR (YAML::ParseException); when trying a YAML.mapping via from_yaml

02:09 <FromGitter> <renich> any idea why?

02:09 <FromGitter> <renich> The yaml file is valid

02:19 <FromGitter> <renich> OK, from_yaml needs a String or an IO... hehe

02:20 <FromGitter> <renich> man, I am tired...

02:47 <crystal-gh> [crystal] akzhan closed pull request #4686: skip_file macro replaced with skip macro. (master...skip_file-macro-replaced-with-skip-one) https://git.io/vQo0T

07:05 <FromGitter> <schoening> Ok why on earth am I getting this error: undefined method 'velocity' for Component (compile-time type is Component+) ⏎ ⏎ ```code paste, see link``` ⏎ ⏎ Am I not checking correctly? [https://gitter.im/crystal-lang/crystal?at=59608434c101bc4e3a63af8c]

07:25 <FromGitter> <schoening> A found it

07:26 <FromGitter> <schoening> Just had to set Component to abstract class

07:33 <FromGitter> <schoening> And swapped it out with hash. Much nicer ^^

09:02 <FromGitter> <konovod> @schoening btw it's better to use `if move_component.is_a?(MoveComponent)` - it will restrict type so you will be able to use specific methods of MoveComponent without downcast.

09:06 <FromGitter> <schoening> Oh i thought if would do that too. Thank you :)

13:35 <FromGitter> <krypton97> how can I pass callbacks in crystal?

13:43 <FromGitter> <krypton97> I think that Proc might be what I'm looking for

13:53 <FromGitter> <schoening> Yes no lambdas ..

13:59 <FromGitter> <krypton97> I got it working with this one

13:59 <FromGitter> <krypton97> https://play.crystal-lang.org/#/r/2bn5

14:00 <FromGitter> <krypton97> Wondering if there's a better way to do it

14:04 <oprypin> do what

14:04 <FromGitter> <krypton97> I'm close to figure it out

14:04 <FromGitter> <krypton97> https://play.crystal-lang.org/#/r/2bnf

14:04 <oprypin> what

14:04 <FromGitter> <krypton97> I don't get the issue

14:06 <FromGitter> <krypton97> This

14:06 <FromGitter> <krypton97> https://play.crystal-lang.org/#/r/2bni

14:07 <FromGitter> <krypton97> seems that the data type is mandatory

14:07 <oprypin> yes it is for Procs. now, what are you trying to do?

14:08 <oprypin> because you could do this but i dont know if it's applicable https://play.crystal-lang.org/#/r/2bnm

14:10 <FromGitter> <krypton97> I'm trying to implement a httprouter

14:11 <FromGitter> <krypton97> Will need callbacks to use middlewares on request/response

14:11 <oprypin> it is difficult. see what Kemal does

14:43 <wmoxam> /opt/crystal/embedded/bin/crystal: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by /opt/crystal/embedded/bin/crystal)

14:43 <wmoxam> ^^ getting this in Travis-CI, any ideas?

14:43 <wmoxam> (https://travis-ci.org/wmoxam/liquid-crystal/builds/251496267)

14:46 <oprypin> :(

16:29 <FromGitter> <ylluminate> Nanobox is willing to give us some love if we can throw some upvotes to the feature request + give them some links and/or instructions on how to configure crystal:

16:29 <FromGitter> <ylluminate> https://trello.com/c/belEWLqo/60-crystal

16:30 <oprypin> what is this?

16:31 <FromGitter> <johnjansen> https://nanobox.io/

16:31 <Papierkorb> *scroll*

16:31 <Papierkorb> ...

16:31 <Papierkorb> what is that

16:31 <oprypin> ikr

16:31 <FromGitter> <johnjansen> haha, trying to work it out myself

16:32 <FromGitter> <ylluminate> basically a heroku replacement based on docker. makes dev/deployment pretty slick and more affordable

16:33 <oprypin> too old for that

16:33 <FromGitter> <ylluminate> from what i'm seeing it supports linode and digital ocean out of the box, but they've got other things coming. i've been talking to them about setting up a method for allowing dedicated host or larger server deployment so that it would make it easy to deploy a bunch of nanboxes to a single server through the dev and testing cycle before deploying to linode or google cloud, for ex.

16:33 <Papierkorb> Don't see a point either. If you know what you're doing, Docker deployment is really simple. If you don't know what you're doing, Heroku makes sure you're not getting constantly owned.

16:34 <Groogy2> Hello

16:34 <FromGitter> <ylluminate> pretty slick and i think i'm going to move away from heroku after playing with it a bit on my rails apps

16:34 <FromGitter> <ylluminate> honestly, if you don't have any other reason to want it, do it for marketing for crystal

16:35 <FromGitter> <ylluminate> if it's supported it will just make more ppl see it , so throw it an upvote if you're not interested anyway

16:44 <FromGitter> <sdogruyol> @Groogy2 hey there

17:19 <FromGitter> <codenoid> hi

17:20 <FromGitter> <codenoid> can i send HEADER data with crystal HTTP client ?

17:21 <FromGitter> <sdogruyol> @codenoid yes

17:21 <FromGitter> <sdogruyol> https://github.com/kemalcr/kemal/blob/master/spec/context_spec.cr#L21

17:22 <FromGitter> <codenoid> <3

17:30 <jokke> hey

17:31 <jokke> is it possible to set HTTP version to 1.0 somehow?

17:32 <FromGitter> <codenoid> ` #<HTTP::Request:0x1956e40> `

17:32 <FromGitter> <codenoid> i dont have this function `call_request_on_app`

17:32 <FromGitter> <sdogruyol> That's not needed...

17:32 <FromGitter> <codenoid> request.body return empty

17:36 <FromGitter> <codenoid> what `#<HTTP::Request:0x1956e40>` mean ?

18:36 <FromGitter> <konovod> @wmoxam Travis is broken for everybody, perhaps will be fixed in Crystal 0.23.1

19:48 <wmoxam> @konovod ah, good to know. Thanks

21:05 <FromGitter> <elorest> I love the idea of nanobox supporting crystal. :+1:

21:08 <FromGitter> <jsilverMDX> :+1: :gem:

21:35 <FromGitter> <oprypin> now i made it so these emojis will also show up properly in IRC 👍 💎

21:36 <Papierkorb> my client doesn't even display them

21:36 <Papierkorb> which is fine, otherwise they'd be so small that I can't distinguish anyway

22:29 <FromGitter> <jsilverMDX> yo guys... gnupg server is slow to add keys on ubuntu when setting up apt-get to install crystal.. anyone else have this problem.. ive had the problem on Debian too

22:29 <FromGitter> <jsilverMDX> ok now it did it

22:29 <FromGitter> <jsilverMDX> i believe gnupg is slow

22:29 <FromGitter> <jsilverMDX> lol

22:38 <FromGitter> <fridgerator> i always have issues with the keyserver

23:29 <ragmaanir> hi, is there currently a working version of crystal for alpine (docker)?
