How do I write this kind of pattern in Kotlin?

while ((line = inp.readLine()) != null) {
            result.append(line)
        }

funrep: Very idiomatic way:

generateSequence { inp.readLine() }.forEach { line -> result.append(line) }

Or, with references: ~~generateSequence(inp::readLine).forEach(result::append)~~
(Doesn't work)

or

File("").forEachLine { ... }

👍 5

or

File("").readLines()

👍 1

This whole

result.append(line)

looks very unclean, should be

map

at least
