I have the same error :

- `crystal (>= 0.36.0)` required by `kemal 1.0.0`

but I am using crystal 1.0.0, why it's still writing this error ?

erdnaxeli

@erdnaxeli:cervoi.se

[m]

there are other lines, especially "- crystal (< 1.0.0) required by radix 0.4.0" and "- crystal (< 1.0.0) required by kilt 0.4.0"

roduquen

@roduquen

You mean that it s just written because of other lib ?

erdnaxeli

@erdnaxeli:cervoi.se

[m]

those libs do not work with crystal 1.0 yet

roduquen

@roduquen

radix is on 1.0.0

erdnaxeli

@erdnaxeli:cervoi.se

[m]

what is your full error message?

roduquen

@roduquen

this one

@Dan-Do

I don't have this issue. I don't use shard install, just download the shard manually on github, extract the files then compile

roduquen

@roduquen

kilt and radix are updated

Yep it s shards that is responsible of the error

erdnaxeli

@erdnaxeli:cervoi.se

[m]

that's not the full message

roduquen

@roduquen

oh sorry

Failed to resolve dependencies, try updating incompatible shards or use --ignore-crystal-version as a workaround if no update is available.

erdnaxeli

@erdnaxeli:cervoi.se

[m]

ok it does not say much more :p

did you try updating?

roduquen

@roduquen

I don't really get what is updating with shards ^^'

shards update run the same error

erdnaxeli

@erdnaxeli:cervoi.se

roduquen

@roduquen

In reality it works locally with --ignore-crystal-version but it's a problem for travis build, and I guess that's normal that they didn't allow this on their build

erdnaxeli

@erdnaxeli:cervoi.se

[m]

I have a similar error as you

kemalcr/kemal#604

roduquen

@roduquen

Yep I just saw on kilt repo that they are on 0.6.1

erdnaxeli

@erdnaxeli:cervoi.se

[m]

yeah but kilt 0.4.1 should have fixed it…

the previous error that CaDs (Carlos Donderis) had was about radix ard kilt 0.4.0, but the versions 0.4.1 should be ok now :/

roduquen

@roduquen

^^ it looks that nop, I hope update kilt to 0.6.1 in kemal requirements will solve this

erdnaxeli

@erdnaxeli:cervoi.se

[m]

I don't see how, the "crystal" field in shards.yaml is the same

roduquen

@roduquen

I am checking kilt commits, I don't find the commit to 0.4.1, just see from 0.4.0 to 0.6.0 on master, and then from 0.6.0 added crystal < 2.0.0, then bump to 0.6.1

erdnaxeli

@erdnaxeli:cervoi.se

[m]

the commit is here: jeromegn/kilt@772ad9e

roduquen

@roduquen

Humm, while checking at commit tree from master it s not here anymore

the one that follow the previous : jeromegn/kilt@d177f02 is this one : jeromegn/kilt@bfd630f

erdnaxeli

@erdnaxeli:cervoi.se

[m]

yes, the commit I linked is not on master

roduquen

@roduquen

oh yep I see this branch

Hi all, I know that Kemal handlers are resolved to the top-level, so placing them in classes with instance variable access is not possible, e.g:

class HelloHandler
  def initialize(msg : String)
    @msg = msg
  end

  get "/" do |env|
    @msg
  end
end

I've also looked at Kemal.config.handlers but the call method only seems to work as a passthrough for middleware chaining. Does Kemal have much in the way of modular support?

Cheers!

What I does it

module SomethingApi
  def self.setup(service)
    get "/" do |env|
      service.do_something
      "something"
    end
  end
end

not sure if it helps ^^

Ah, thank you, @erdnaxeli! I’ll give this a go when I’m back at my laptop 🙂

Coding Concepts

@codingconcepts

It works beautifully! Thanks again, @erdnaxeli 🙏

erdnaxeli

@erdnaxeli:cervoi.se

[m]

You're welcome :)

:point_up: Edit: What I does is

module SomethingApi
  def self.setup(service)
    get "/" do |env|
      service.do_something
      "something"
    end
  end
end

Coding Concepts

@codingconcepts

Hi @erdnaxeli, sorry, do you have an example of this being setup for a spec? I’m calling my module to configure the routes but Kemal’s enumerable of handlers remains empty when my spec gets called 🤷‍♂️

erdnaxeli

@erdnaxeli:cervoi.se

[m]

no sorry. I didn't try to test directly the kemal handler yet.

Coding Concepts

@codingconcepts

No worries at all! If i manage, I’ll share back 🙂

Coding Concepts

@codingconcepts

Hey @erdnaxeli, solved for when you get round to testing your handlers :)

Spec.before_each do
  config = Kemal.config
  config.env = "test"
  config.setup
end

Spec.after_each do
  Kemal.config.clear
end

...in addition to calling SomethingApi.setup

Nice!

Hello everyone! Does anyhow here know how to run Kemal in silent mode ie without "Kemal doesn't know this way." screens and without any message when there is an execution error?

ddd

@Dan-Do

just overwrite the method error_400 and error_500?

Johannes Müller

@straight-shoota

the error page with stack trace etc. should only be shown in development mode

For adjusting the normal error page, see https://kemalcr.com/guide/#custom-errors

Alex Kampa

@alex-kampa

thanks @Dan-Do and @straight-shoota

Hi, I am new to Kemal (and to Crystal as well). It seems to me that in the spec when I have a get "/blabla" to a URL that does not have a matching route, I get 200 OK. (Unlike when I run the application in which case I get 400 Not found as expected) Am I doing something incorrectly or is this the expected behavior?
