# scripting

[Geert]

I was looking in the kotlin-script-examples project and wondering if it is possible to use your own class as a base class for the script to run in (so that the this of the file is of a type of your own choosing), a la gradle?

[Adam S]

Yes, it is. If you're looking for an example, I like this guide: https://scastiel.dev/kotlin-scripts-dsl-underrated-feature

[Geert]

Awesome! Will have a look!

[Geert]

Hmm, that doesn’t really change the this of the file, if I understand correctly.

[Geert]

However, it gave me an idea: what I really wanted was to use Kotlin script build some configuration. That I can do with some dsl that just returns the configuration I’m interested in.

[Geert]

But it requires the user to have the dsl invocation as the last statement. 🤔

[Adam S]

hmmm I thought it did allow setting the base class, see step 3 here https://kotlinlang.org/docs/custom-script-deps-tutorial.html#create-a-script-definition

In scriptDef.kt, create a class. It will be a superclass for scripts of this type, so declare it abstract or open.

[Geert]

I’ll try to get it running, then I can see and I’ll let you know. First invalidate some caches. 😉

[Geert]

You were right, I got the example running and added this in the script:

val x = this
println(x.javaClass.superclass)

result:

class nwt.script.NwtScript

nice!
