Is something like this possible in kotlin?
https://pl.kotl.in/Byi2Xz5q7

[gildor]

Just add param name:
{ it -> it?.length ?: -1 }

[gildor]

Or maybe I don’t understand your case

[jeggy]

I just wanted to know if I can write it in some way without the it -> part.

[jeggy]

if it's not inside a map I can do it

[gildor]

You cannot, because type inference doesn’t support such case

[marstran]

This could be something that is supported in the new type inference engine, but I'm not sure.

[jeggy]

that would be really nice. You know where I can follow on the type inference engine development?

[marstran]

I heard about it in Svetlana Isakova's talk on KotlinConf.

[marstran]

I can't find it on youtube yet, but it should be up soon I'd guess.

[gildor]

You can use som DSL instead for such cases to avoid this problem, but hard to recommend particular syntax without context

[jeggy]

I have created a function that can take a mapping of Map<Any?, (String) -> Any?).
So I just wanted to shorten wherever it was used. Like from this: line -> line?.toIntOrNull() into it?.toIntOrNull 😉

[Nikky]

you could change this to take String.() -> Any?

[Nikky]

then you can use this.. or ignore it and have no parameters, your choice.. might look cleaner

[dsavvinov]

Actually yes, that works in New Inference
