Scala: write string to file in one statement

Question

For reading files in Scala, there is

Source.fromFile(\"file.txt\").mkString

Is there an equivalent and concise way to write a string to fi

Answer 1

This is concise enough, I guess:

scala> import java.io._
import java.io._

scala> val w = new BufferedWriter(new FileWriter("output.txt"))
w: java.io.BufferedWriter = java.io.BufferedWriter@44ba4f

scala> w.write("Alice\r\nBob\r\nCharlie\r\n")

scala> w.close()

Answer 2

Here is a concise one-liner using reflect.io.file, this works with Scala 2.12:

reflect.io.File("filename").writeAll("hello world")

Alternatively, if you want to use the Java libraries you can do this hack:

Some(new PrintWriter("filename")).foreach{p => p.write("hello world"); p.close}
