More support for ranges

[AlexCue987]

Examples:

• (0..2) shouldOverlapWith (1..3)
• (2..3) shouldBeIn (1..4)
• (0..1) shouldNotOverlapWith (2..3)
• (4..5) shouldNotBeIn (1..3)

should support both ClosedRange and OpenEndRange.

I'd like to do it if this feature is needed.

I think add support shouldBeIn range would be hard. But maybe creating new function can be solution.

got it. how about this (2..3) shouldBeInsideOf (1..4)

think we have to specify which type we should accept only range? or other list types

[mirageoasis]

if maintainer says yes maybe I can add method to support this proposal

only ranges. It does not make sense for lists

[sksamuel]

What about

(0..2) shouldIntersect (1..3)
(2..3) shouldBeWithin (1..4)

What about

(0..2) shouldIntersect (1..3)
(2..3) shouldBeWithin (1..4)

let's use these function names

I think there should be some careful approaches about ranges since it has backward range

[mirageoasis]

I think there should be some careful approaches about ranges since it has backward range

and think we need to add support for until
or maybe can I get until feature assigned?

[sksamuel]

I think there should be some careful approaches about ranges since it has backward range

backwards or forwards, still comprises a set of numbers, so within should be fine.

[LeoColman]

I'd also enforce that we should try to go for an strictly correct mathematical definition.

Sets theory is very well defined, ie

• A set within a set
• An open ended range
• A close ended
• etc

[sksamuel]

I will release 5.8.1 from what is on main in a few days, then whatever comes after will move to 5.9 which is will be kotlin 1.9+

implemented only intersect #3792
