    Oops, sorry, it’s slightly different.

    Copy code
    inline fun <T : Any> given(condition: Boolean, body: () -> T): T? =
    if (condition) body() else null

    I thought a couple times about this version, too. but I wanted to reuse the safe-call operator instead of creating a different scope

    I think these functions are used for different purposes. That’s how we use it:
    Copy code
    given(changes.hasValue()) { changes.value }

    @kirillrakhman: shouldn't that read 
    condition: (T) -> Boolean
    if you want to use 
    it

    yeah, you're right

    I made it an extension lambda first, but it reads more like English when you have 
    it
    in there

    04/08/2016, 1:46 PM
    yeah, I kinda like it

    should we create an issue to promote it to stdlib?
  • k

    kirillrakhman

    04/08/2016, 1:47 PM
    or do you feel it's not suited?
  • u

    uhe

    04/08/2016, 1:49 PM
    well I would vote for it, but I'm not that familiar with what makes a good stdlib extension

    any opinion by @orangy or any other JB dev?

    @kirillrakhman: Lot of similar functions in 
    Preconditions.kt
    , e.g. 
    requireNotNull(project.version, { "version mandatory on project ${project.name}" })

    @cedric: they all throw

    I find a library function that is suppose to be used in conjunction with another language feature a bit tricky to be part of the standard lib

    I think there is an issue like this, but I’m not sure.

    is implementing parallel streams (parallel sequences) planned in near future?

    @rafal: no plans to build our own implementation, but we do plan to offer JDK 8 streams out of the box when you’re targeting Java 8

    nice simple smile any solutions for pre-java8

    thanks @kirillrakhman I do hope, I won't have to deal with java7 or later but who knows

    I have a question about `kotlin.io`'s 
    use
    . Suppose I wanted to simply copy an InputStream to an OutputStream and make sure both streams are closed. Would the following be considered idiomatic or is there a cleaner/simpler way?
  • m

    Copy code
    response.bodyStream.use { input ->
    buffer.use { output ->
        input.copyTo(output)
    }
}

    (assume 
    response.bodyStream
    is an 
    InputStream
    and 
    buffer
    is an 
    OutputStream
    , naturally)

    @michaelsims: Hmm, seems we need to use 
    use()
    .
