With the following code: ```private val configRegex = Regex("^Config=(.+)$", RegexOption.MULTILINE) ...

# multiplatform

With the following code:

private val configRegex = Regex("^Config=(.+)$", RegexOption.MULTILINE)

internal class ServerExtensions {
  ...
}

Is it possible to generate a single .class file?
I recall @mbonnin suggested JvmMultifileClass but it seems it's not applicable here

[mbonnin]

You'll have one class for holding your top level val and another one for ServerExtensions

[mbonnin]

Why do you want everything in the same class?

[Edoardo Luppi]

Well it would make more sense logically since that regex is only used inside ServerExtensions .
Not mandatory, but was just curious if it's feasible

[mbonnin]

You can always move the val inside your ServerExtensions

[mbonnin]

If there are no top level declaration, the Kotlin compiler should skip generating a class

[mbonnin]

But this is all implementation detail in all cases. Unless you care about Java compat and/or some optimizations, that should not matter much

[Edoardo Luppi]

Yeah I've just ended up with

private companion object {
  private val configRegex = Regex("^Config=(.+)$", RegexOption.MULTILINE)
}

The funny thing is now configRegex is a static field of ServerExtensions , and I got an instantiation of an empty Companion lol

[mbonnin]

You can certainly remove this with @JvmStatic if you really want to but...🤷

[Edoardo Luppi]

Seems like it's impossible to get rid of the useless companion class.
Not a big deal tho

[mbonnin]

I'd say the companion is still used to hold some Kotlin metadata for the compiler but 🤷

[Edoardo Luppi]

Indeed there is metadata attached via the annotation.
No problem! Thanks btw!
