02/14/2017, 8:58 PMIn the Kotlin reference, it says
. Is there any timeline on when that support would happen?break and continue are not yet available in inlined lambdas, but we are planning to support them too - e

02/14/2017, 9:18 PMthanks @elizarov - n
nstewart
02/14/2017, 9:20 PMSo based on that ticket there are no plans to support break and continue? - k

andBooleanArray.any()
not being the sameBooleanArray.any { it } - k
kirillrakhman
02/15/2017, 9:52 AMwhat's the reason for having
if there isany()
?isNotEmpty()❓ 1 - o

02/15/2017, 10:56 AMwell, Map is often called associative array, henceassociate - m

02/17/2017, 6:28 PMAnother example:Copy codeprivate fun getCollisionGroups(eventRects: List<EventRect>): List<MutableList<EventRect>> = eventRects .sortedBy { it.event.startTime } .fold(listOf<MutableList<EventRect>>(), { acc, elem -> val collision = acc.firstOrNull { it.any { potentialCollision -> isEventsCollide(potentialCollision.event, elem.event) || (potentialCollision.event.isAllDay && elem.event.isAllDay) } } if (collision != null) { collision += elem; acc } else acc.plusElement(mutableListOf(elem)) }) - m

02/17/2017, 6:33 PMI didn’t found any tool for that 😕 - m
marcinmoskala
02/17/2017, 6:33 PMMy proposition:Copy codefun <T> Iterable<T>.groupTogether(f: (List<MutableList<T>>, T) -> MutableList<T>?): List<MutableList<T>> { return fold(listOf<MutableList<T>>()) { acc, elem -> val chosenGroup = f(acc, elem) if (chosenGroup != null) { chosenGroup.add(elem); acc } else { acc.plusElement(mutableListOf(elem)) } } } - m

02/17/2017, 6:35 PMCopy codeval columns = collisionGroup.groupTogether { columns, eventRect -> columns.firstOrNull { column -> !isEventsCollide(eventRect.event, column[column.size - 1].event) } } - m
marcinmoskala
02/17/2017, 6:36 PMCopy code.groupTogether { acc, elem -> acc.firstOrNull { it.any { potentialCollision -> isEventsCollide(potentialCollision.event, elem.event) || (potentialCollision.event.isAllDay && elem.event.isAllDay) } } } - m

02/18/2017, 10:54 AMAny comments? - m
marcinmoskala
02/18/2017, 10:57 AMIf I will have some agreement, then I will implement it universally, add tests and create pull request. But already some of my ideas are waiting in pull requests, so I prefere to ask community xP - m
marcinmoskala
02/18/2017, 10:59 AMIdea of this function is simple. Each element is finding the group he likes the most, or creates new one (by returning null in lambda). - a

02/18/2017, 3:58 PMWhy not move
into the extension too? Do you see any use-cases with test function inspecting more than one result group?firstOrNull - j
