Is there a function buried in the std lib somewhere that makes this more succinct? Trying to parse something like "1234 abcd" to 1234

val myInt = someString.takeWhile { it.isDigit() }.toInt()

What do you mean by more succinct? If you want fewer characters:

val myInt = someString.split(' ')[0].toInt()

I remember from something (maybe a different language like python?) which was a bit more lenient with integer parsing and grabbed the first bit of a string that was a number. Not sure if there's a function that does this in Kotlin or Java

[hho]

Javascript does this (shudder).

Ah that's probably what I was remembering haha

I believe that is the way GDScript works for the Godot game engine as well. It has been the source of more than one bug for me.

Glad I checked here then. Hopefully the integer parsing behavior is more likely to stick in my brain after this interaction. Probably not though. lol

Another possibility (just a possibility, not a recommendation):

val myInt = java.util.Scanner(someString).nextInt()

Scanner is too heavy a class for this purpose; I would just keep your original code.
