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) }

[funrep]

nice that looks good, thanks!

[diesieben07]

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

[voddan]

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

[voddan]

or File("").readLines()

[voddan]

This whole result.append(line) looks very unclean, should be map at least
