11:43 <rolha> hi everyone

11:43 <rolha> sorry for not being 100% related to Crystal, but I'm doing a hobby web project in Kemal

11:44 <rolha> and I'm used to netty or node as a wev server, what's the best way to restart a crystal app (Kemal in this case) if it crashes? I'm using ubuntu.

11:46 <rolha> should I just use something like upstart?

11:55 <BlaXpirit> rolha, something like upstart but not upstart

11:56 <rolha> BlaXpirit: ahah, thanks :) is it that bad?

11:56 <BlaXpirit> rolha, it is not used in any major distro anymore

11:56 <yxhuvud> I'd use whichever is installed of upstart or systemd.

11:56 <BlaXpirit> Ubuntu 14.04 uses it but latest version does not

11:57 <rolha> I've used npm's forever, but wanted to do a node detox :-P

11:57 <rolha> so I'll see what's in store for ubuntu

11:58 <rolha> thank you!

12:02 <BlaXpirit> rolha, https://bpaste.net/show/5a6ec00d2a3a

12:04 <rolha> BlaXpirit: that's brilliant! Thank you! :)

12:04 <BlaXpirit> rolha, but i still don't know what system you're on, maybe there is no systemd

12:05 <rolha> it's Ubuntu 15, if I'm not mistaken it has systemd now

12:05 <BlaXpirit> ok

12:06 <rolha> if not, I'll just install some distro which has it

17:53 <Rinkana> BlaXpirit, ah i thought so. But can i at least call a function of a class with a string?

17:54 <BlaXpirit> Rinkana, uh sure, that sounds completely normal

17:54 <BlaXpirit> Rinkana, why don't you explain what you're actually trying to do

17:56 <Rinkana> What i am trying to do is creating something like the Rails route system. I want to create a simple method of defining new routes

17:56 <Rinkana> Something like:

17:57 <Rinkana> add_route "GET", "/", [Controller], [Method]

17:57 <Rinkana> First i wanted to write it like this: add_route "GET", "/", "Index@Index"

17:57 umurgdk has quit [Ping timeout: 252 seconds]

17:58 <Rinkana> But since i cant create objects based on a string i tought i'd padd the controller class and as a string the method i want to call.

18:18 <Rinkana> BlaXpirit i've tried calling the send and method functions that ruby has however it seems they are not in Crystal. Is there another way to call the method by string?

18:18 bcardiff has joined #crystal-lang

18:18 <BlaXpirit> Rinkana, no...

18:18 <BlaXpirit> Rinkana, why don't you check out existing web frameworks

18:42 <asterite> Rinkana: you should read this: https://github.com/crystal-lang/crystal/issues/949

18:43 <crystal-gh> [crystal] ethe opened pull request #2408: fixed https://github.com/crystal-lang/crystal/issues/2393. (master...add-cc-flag) https://git.io/vVBWa

18:43 <asterite> And also, it's better if we all focus on one/two web frameworks instead of creating thousands of them. Right now I'd say kemal is pretty good/popular, and there's also frost which is more Railsy
