I'm trying to build a system to run kts scripts at runtime, ideally with some sort of environment context (i.e access to the full classpath, for some backend stuff, personal project) - is this possible with the current state of kotlin scripting?

[Adam S]

Do you want to run a Kotlin script from another JVM process?

[Amo]

Yeah! The idea is to have sort of scripts i can call to run from some arbitrary method

[Adam S]

Okay, cool. Try taking a look at the answer here https://stackoverflow.com/questions/76484985/is-there-a-way-to-instantinate-kts-script-engine-in-the-gradle-kts/76505455

It explains how to launch a .kts from a Gradle task - but because Gradle is JVM based, it'll contain a lot of similar info!

[Amo]

Hm, I'm not really sure how to use this - but it requires Configurations, I don't know if i can use them at runtime? i've never tried before

[Amo]

The idea here for anyone else who may see it - I want to be able to effectively call and run any arbitrary script an admin user wants to run - also allowing "automatically" ran scripts to be hotfixed should an issue arise without having to take the backend down

which ide you are using

Sorry, that answer might be a bit confusing if you're not familiar with Gradle. I'll re-explain :)

The main points are the required dependencies:

• org.jetbrains.kotlin:kotlin-compiler:$kotlinVersion
• org.jetbrains.kotlin:kotlin-scripting-compiler:$kotlinVersion
• org.jetbrains.kotlin:kotlin-main-kts:$kotlinVersion
And then import org.jetbrains.kotlin.cli.jvm.K2JVMCompiler to compile and run the scripts. It's got a main(args) function, that you can just call and pass in some args.

Most of the args are pretty standard. The trickier part is passing in the runtime classpath in the -classpath arg.
