kotlinlang

is there a more idiomatic way in kotlin to write sth. like this? ```while (true) {
    val rows = repo.findAll(page)

    if (rows.isEmpty()) {
        break
    }

    doSomething(rows)
}```

```
sequence { yield(repo.findAll(page)) }
  .filter { it.isNotEmpty() }
  .forEach(::doSomething)
```
:thinking_face:

You could do
```
val rows = logRepository.findProcessable(page).takeUnless { it.isEmpty() } ?: break
doSomething(rows)
```
Which some might more "idiomatic", however personally I don't think an if statement is "not-idiomatic" (whatever that means).
Everyone understands if statements so there is nothing wrong with your code.

```
generateSequence { 
  repo.findAll(page).takeIf { it.isNotEmpty() } 
}.forEach(::doSomething)
```
or
```
generateSequence { 
  repo.findAll(page).takeUnless { it.isEmpty() } 
}.forEach(::doSomething)
```

<@U589QURRQ> your code would break the idea of processing one page at a time right? It would collect all rows and process them afterwards right?

No, my code was supposed to go inside the `while(true)` loop

I just refactored the is-empty-then-break part of it

need to read up a few methods, thanks so far

```
generateSequence { repo.findAll(page) }
  .takeWhile { it.isNotEmpty() }
  .forEach(::doSomething)
```
