Is there anyone here that knows Clojure?

[Nate Smith]

any reason in particular?

[Joakim Tengstrand]

In Clojure you can import a namespace like ":require [user.core :as core]" and then access functions in the 'core' namespace like core/myfunction. I couldn't find a way to do the same. I don't want to import all functions in the core namespace. I want to access them via an "alias".

[Joakim Tengstrand]

I solved it by using companion objects.

[Michael de Kaste]

you can import as

import org.test.Message as testMessage

[Joakim Tengstrand]

But isn't that only used for classes? If you only want an alias to the namespace and then use it to access different functions in that namespace, like myns.func1(), myns.fnc2(), then I couldn't find an example of how to do that.

I know clojure, Kotlin basically doesn't have namespaces, only packages.. There are a few approaches to emulating namespaces but none of them are great. Writeup here: https://arturdryomov.dev/posts/namespacing-in-kotlin/

Java 9+ also has a module system (again not quite the same as namespaces but related)

[Joakim Tengstrand]

I solved it like this:

package user

object Interface {
    fun theUser(): String {
        return user.core.theUser();
    }
}

[Joakim Tengstrand]

Then I use user.Interface as a namespace:

package tool

import user.Interface as User

fun main() {
    println("Current user: " + User.theUser())
}
