    Kotlin stdlib could use a URI class, because java.net.URI is horrible.

    I'm building a product/company that will need a android app, an ios app, a spring+kotlin backend and an angular cli frontend. So far trying to do all these in a single IntelliJ window has proven tough, so I sort of decided to run them as separate projects even though they are related to the same overall product. I sort of wanted to have them all in a single git repo, but I'm thinking now about separating them their too.... but then I might use kotlin native/multiplatform for the ios/android stuff so suspect a single git is better for this... trying to lay this out. Should I do 4 repos or one? How would I or do I want to treat these as one intelliJ project?

    One other Question: I'm looking for project management software... I am used to managing multi discipline multi million dollar project using Excel for action items and Word for project planning, or alternatively MS Project/Primavera real PM software. I've used youTrack, trello, jira and I really really hate all three... jire and trello seem to manage project by sticky notes in swimlanes and youTrack is complicated and verbose, but provides less relevant functionality than excel and word for me. Bottom line, I want to use this modern developer PM software, but one thing I absolutely have to have is a tabular view with real columns, filter/sort without having to learn proprietary query languages... basically I need a real spreadsheet + pretty views for all the other people not managing the project.... Do any offer this?

    Is there an easy way to interop between Kotlin `data class`es and more traditional libs that require Bean/POJO annotations? If I’m using a lib that requires annotations on a POJO/bean as well as normal getters/setters, I’d like to use a 
    data class
    but I don’t think I can apply annotations to those fields.

    Am i wrong to expect this to compile?
    Copy code
    sealed class Item {
    data class Foo(val id: Int) : Item()
    object Bar : Item()
}

fun List<Item>.trim() = dropLastWhile { it is Item.Bar || it.id == IGNORED_ID }
    It works if I do 
    it !is Item.Foo || it.id == IGNORED_ID
    though, which is understandable

    is there a trick to implementing preincrement for an inline class wrapping an int? post-increment is working fine for me but preincrement isn't

    Hey, I'm a Vaadin guy but the recent changes on it are making me re-think it... Also, if I lose Vaadin I'd be inclined to drop Spring too since I already dropped Spring-data. Any advises on a web framework to create UIs on the server-side like Vaadin that would be nice to work with Ktor?

    How can I have a type that represents a Double that is within a given range? For example I’d like to have a type that holds a double that is guaranteed to be between 0 and 1. I had a look at 
    inline class
    but it does not provide 
    init
    so I have nowhere to place an 
    assert
    . Any ideas?

    Hello, World! A small API design question: I'm making a lib in Kotlin, and want to make it nice to use from Kotlin and Java. One method takes a date range as a parameter so I used a 
    Pair<Date>
    for it. This way from Kotlin it's nice, you can do 
    foobar(dateFrom to dateTo)
    . But from Java you're going to have to do 
    foobar(new kotlin.Pair<>(dateFrom, dateTo))
    and now you need Kotlin in your dependencies for this to work - not cool. Ideally I'd like to have both 
    to
    and not this Java issue... Ideas?

    is there a multi-platform way to check if a variable (of type

    v is Function<*>

    Could anyone explain why this works
    Copy code
    val longs = List(100) { random.nextLong(6868L) }
assertThat(longs.all { it < 6869L }).isTrue()
    But when I use property access syntax for 
    isTrue
    it throws 
    Cannot infer type parameter SELF in val <SELF : AbstractBooleanAssert<SELF!>!> AbstractBooleanAssert<SELF>.isTrue: SELF!
    Copy code
    val longs = List(100) { random.nextLong(6868L) }
assertThat(longs.all { it < 6869L }).isTrue
    I'm using assertJ. Just wondering if this is kotlin or assertj issue.

    Hi! What is the recommended approach to create an object, mutate it a little bit and then make it immutable? I use the following steps right now. A parent object has children mutable fields. Firstly, I create a parent object. Secondly, I create a child object. Then I set the parent object to the child object field. Thirdly, I set child field to the parent object. Lastly, I persist parent object.
