while (true) { } might be simplified to while { }

[Dominaezzz]

There's a YouTrack for this one actually. I'll find a link.

thanks!

[jimn]

what about repeat{} ?

[elect]

it sounds weird

[Leon Linhart]

while { } feels wrong because "while" implies that the code is executed while some condition is true which is not the case for an infinite loop. (for { } suffers from a similar problem.)

[elect]

logically, you should have a point. However given I'm used to read that in C, it feels natural

[Dominaezzz]

loop { }

[stantronic]

inline fun loop(block: ()->Unit){ 
   while(true) block.invoke()}

[stantronic]

(except that wont work with break and continue)

[jimn]

this thread is a mirror of the youtrack issue. it seems like the path of minimum resistance is probably something{...}
however '...' as an operator is an infinite range semantic. does ... simply alias to Any?..POSITIVE_INFINITY ? will thaat be a follow-up stdlib request to try to reduce gap from maths to source code?

[Ky Leggiero]

@stantronic If you find yourself using break and continue in a while (true) block, you should instead be looking at other, better-fitting patterns. Perhaps the condition that causes you to hit break should be in the parentheses instead of true, or perhaps you should be using for, filter, any, etc.
