How do I get to the actual stdlib-sources of - say - the min() function in Intellij?
When I do STRG-B it loads _Collections.kt from the generated folder of the kotlin-stdlib-xxx-sources.jar - which is not the actual source I guess. When I browse the kotlin\collections folder instead I find CollectionsKt.class but this does not include the min() function.

A "Search everywhere" doesn't help either.

What is this generated folder about anyway? Who generates it and why? 😅

which is not the actual source I guess.

It's the actual source. However due to a significant code duplication between collections, arrays, sequences etc, the source of most collection operations is generated from a template.

I see, thank you, Ilya!

At first I was a bit let down because the (generated) code looks so Java-ish 😅

val iterator = iterator()
if (!iterator.hasNext()) return null
var min = iterator.next()
while (iterator.hasNext()) {
    val e = iterator.next()
    if (min > e) min = e
}
return min

I had expected something like

with(iterator()) {
    if (!hasNext()) return null
    var min = next()
    forEach { if (min > it) min = it }
    return min
}
