thank @UG9U7TPDZ what if I don't have that file? probably that's were the problem is...

Using lein run you should have it. Also if you're creating an uberjar you need ["run" ":duct/compiler"] in your prep-tasks

uhm sorry, that's not correct

I think you need the duct middleware in your project.clj :middleware [lein-duct.plugin/middleware]

If you're using deps.edn then you need to do some extra stuff it get it to work. Haven't done it myself but this should help https://github.com/duct-framework/duct/issues/92

Good luck!

One thing I am a bit unfamiliar is the concept of derivation vs composite keys... If I have something like this in config.edn: [:duct.server/http :infra2.server/pedestal] Would that be automatically started? Cause I am getting a No method in multimethod 'init-key' for dispatch value: :integrant.composite/duct.server.http+infra2.server.pedestal_5851 Do I need to explicitely require the namespaces from my main.clj?

Basically the way that it works is that a new keyword is created and derived from all the keywords in the vector. https://github.com/weavejester/integrant/blob/b4f77b0fe9618c5d65bf2cafd27510e8e6ba7cdd/src/integrant/core.cljc#L15-L26

You still have to write an ig/init-key for :infra2.server/pedestal

Duct will try to find an init-key for either keywords, and if it can find 1 it'll initialize it

yep I have that one in place the only missing thing is that it is not required in the main namespace

In development you mean?

oh

no for prod..

You mean the namespace where the ig/init-key is defined is not required by main

(sorry I inherited this code base and trying to understand the various moving parts also)

yeah

If the namespace is either: infra2.server.pedestal or infra2.server it will automatically be required

Because it matches the name of the init key

But if the namespace has a completely different name, it won't be required automatically

yeah it's exactly infra2.server containing a ::pedestal key...strange I got that error

Hmm

Maybe it won't require it if :duct/server is not derived from :duct/daemon

uhm let me try that then

Because it doesn't need to initialize it

I am trying with [:duct/daemon :infra2.server/pedestal]

I think that should work

No method in multimethod 'init-key' for dispatch value: :integrant.composite/duct.daemon+infra2.server.pedestal_5854

very weird...I'll have to dig into the code base

It should require the namespace even if it doesn't get initialized

https://github.com/duct-framework/core/blob/28de7df11af9c95ceb157d0c5163c061a75554b3/src/duct/core.clj#L207-L209

Sorry I can't think of a reason why it's not requiring 😅

Unless you're compiling with graalvm

well in that piece of code I can't see how composite keys are required..

anyways I'll dig...thanks a lot for your help
