<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]

<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.

<krypton97> how can I pass callbacks in crystal?
<FromGitter>
<krypton97> I think that Proc might be what I'm looking for
greengriminal has joined #crystal-lang
<FromGitter>
<schoening> Yes no lambdas ..
<FromGitter>
<krypton97> I got it working with this one
<FromGitter>
<krypton97> I'm trying to implement a httprouter
<FromGitter>
<krypton97> Will need callbacks to use middlewares on request/response
<oprypin>
it is difficult. see what Kemal does

<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:
<FromGitter>
<johnjansen> haha, trying to work it out myself
<FromGitter>
<ylluminate> basically a heroku replacement based on docker. makes dev/deployment pretty slick and more affordable
<oprypin>
too old for that
<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.
<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.

Hello
<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

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

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