Hi, I'm struggling a lot to generate Kotlin code from a certain pattern of items.
Here is a snippet the pattern :

ambient/cave/cave7
ambient/cave/cave8
ambient/cave/cave9
ambient/nether/basalt_deltas/ambience
ambient/nether/basalt_deltas/basaltground1
ambient/nether/basalt_deltas/basaltground2

And I need to generate something like this for this pattern :

sealed interface Sounds : Argument.Sound {
    override val namespace = "minecraft"

    object Ambiant {
        @Serializable(with = Cave.Companion.CaveSerializer::class)
        enum class Cave : Sounds {
            CAVE7,
            CAVE8,
            CAVE9;

            override fun asString() = "$namespace:ambiant/cave/${name.lowercase()}"

            companion object {
                val values = values()

                object CaveSerializer LowercaseSerializer<Cave>(values)
            }
        }
    }

    ...
}

The deep level can varies from 1 to 3 (a/b to a/b/c/d/e ) and I need the serialization thing, and especially the asString() method. For now I have something kinda working but it's made mainly by hand and customized for each files I have with this pattern instead of having a main builder that I use for each ones.

doesn't seem that hard. this prints out

public object ambient {
  public enum class cave {
    cave7,
    cave8,
    cave9,
  }

  public object nether {
    public enum class basalt_deltas {
      ambience,
      basaltground1,
      basaltground2,
    }
  }
}

and of course you can customize it more

Ah I didn't knew there was a library to generate Kotlin code :o
I have done similar methods by hand past this

[ephemient]

if you have kotlinpoet questions you can check #squarelibraries (but if you've used javapoet before it should feel pretty familiar)

[ephemient]

generating by hand is just more boilerplate though

[ephemient]

e.g. this prints

object ambient {
  enum class cave {
    cave7, cave8, cave9;
  }
  object nether {
    enum class basalt_deltas {
      ambience, basaltground1, basaltground2;
    }
  }
}

even if it's more verbose, I'd still prefer kotlinpoet though. it handles all sorts of stuff for you, like imports, string escaping, checking valid names, etc.

Yeah I'll change my generation module to use KotlinPoet
