I've been trying to write a network storage access...

# coroutines

I've been trying to write a network storage access library and I have to admit the lack of suspending properties is making the syntax overly complex. I'd love to be able to do something like:

suspend val size: Long
    get() = remoteServer.getFileSize(this)

Instead, I'm stuck with this:

suspend fun getSize() = remoteServer.getFileSize(this)

So users have to do file.getSize() instead of just file.size 😞

There's a discussion in the forums about this but there has been no interaction from the JetBrains team. Are there any plans to support this?

file.size() vs file.size is not so much different IMO
But agree, suspend properties would be a good addition

[nulldev]

Wow.... That's actually a good idea haha...

[nulldev]

A part of me is still stuck in the Java world where everything is get this and set that

IIRC, the idiomatic Kotlin way is for properties to be very uncosty to access multiple times

[gildor]

it can be uncosty even with suspend just asyncronous, also suspend properties really needed when you convert blocking code with properties to non-blocking and want to keep old API

[bdawg.io]

I was just referring to the remoteServer.... in the OP implementation. I was more referring to network usually being considered more costy

[gildor]

Yes, I’m not sure about particular use case.
But stdlib File.size also does IO access, so there are no strict rules

[bdawg.io]

Yeah, IO in general is fairly costy relative to basic in-memory/compute (which is usually what I've seen properties recommended for at most). Obviously it's just an API either way though
