Hey guys 👋
I’ve just published a kotlinx-datetime-ext library the fills the gap between java.datetime and kotlinx.datetime since java had much more functionalities
you can find it here https://github.com/RaedGhazal/kotlinx-datetime-ext with full documentation on what it provides and how to use it

initially I just wrote a blog post on how to write you own helper functions but then thought of making it even easier by creating the library, will appreciate your support by giving me feedback, opening issues or even contribute! (leaving a star can be also nice ❤️)

Thanks!

[Robert Jaros]

Nice work by why only android and ios targets?

[Raed Ghazal]

Hey @Robert Jaros
Just wrote a reply to this actually here

We can probably easily support other JVM targets actually

[Peter]

is this extension necessary?

val afterFiveDays = localDateTime.plus(5, DateTimeUnit.DAY)

I think kotlinx has this feature:

val afterFiveDays = localDateTime + 5.days

[Raed Ghazal]

oh, does it?

[Peter]

documented under this paragraph I think

[Peter]

sorry, this one https://github.com/Kotlin/kotlinx-datetime#instant-arithmetic

[Raed Ghazal]

just checked, val afterFiveDays = localDateTime + 5.days this won’t work actually
what + 5.days will only work with instants, so you have to convert to instant, do the math, convert back to localdatetime

[Raed Ghazal]

which what this extension function actually does

val afterFiveDays = localDateTime.plus(5, DateTimeUnit.DAY)

[Peter]

ah, okay, that's annoying. Tnx for checking

[Raed Ghazal]

it is, hope my library makes it less annoying 😅

[Raed Ghazal]

but I actually can bring val afterFiveDays = localDateTime + 5.days to my library, I’m just checking something quick, hold on

[Peter]

that would be great yeah, shouldn't be that hard to add I guess

[Raed Ghazal]

its supported now 🎉
check version 1.0.2

[Peter]

Great, thanks!

[Raed Ghazal]

Hey @Robert Jaros what platforms did you want? desktop?

[Robert Jaros]

JS an WasmJs

[Robert Jaros]

I'm a web developer 🙂

[Raed Ghazal]

ah, still surprised of the fact that someone is using KMP already mainly for web development 😄 was under the impression that its mostly Android devs trying to support more platforms


but is this the target you mean? just created a new KMP project with web support using jetbrains wizard

[Robert Jaros]

Yes, but only one of them. JS (jsMain) should be supported as well (wasm is still experimental and js is stable)

[Raed Ghazal]

alright the library supports JVM/Desktop now on 1.1.0 version @Michael Paus
