Not 100% sure where to ask this but out of curiosity, is there a compiler plugin or IDE plugin that can tell me when I pass wrong positional arguments to String.format ?

// I'd like this to fail at compile time and/or show me an error in the IDE
String.format("%d", "10")

Interestingly, it already does, but only for Java files.

Ah thanks! I thought I'd seen this somewhere

[mbonnin]

But haven't been able to make it work in Kotlin files so far

[Eugen Martynov]

I think Android lint does same for the Android strings

[twisterrob]

what happens if you use the Kotlin syntax? "%d".format(10)?

[mbonnin]

@twisterrob same thing (i.e. no warning/error)

I see https://youtrack.jetbrains.com/issue/KTIJ-4352/Add-inspection-Malformed-format-string but it's basically untouched

Good find, upvoted!
