Recommended Scala io library

Question

By all accounts, Scala's Source is a bit of a mess - everything I've read about it mentions resources left open, mysterious bugs...

I was wondering whether that was still the case in recent versions of Scala and, if so, what are worthy alternatives?

I've mostly heard of scala-io and scalaz-streams (and, obviously standard Java IO primitives). Did I miss anything? If anyone has experience with these or other projects, what are their respective pros and cons?

I'm inclined to go for scala-io, since I found the author's blog to be a fairly high quality source of useful of information, but I'd love to know more about the alternatives and what other people use.

Answer 1

Rapture IO might be worth trying.

It provides some nice DSL for managing IO resources of various kinds.

Answer 2

Using the package java.nio.file in Java standard library may also be simple enough if you don't require advance features. For example, to read the lines of a file into memory:

Files.readAllLines(Paths.get("file_name"), StandardCharsets.UTF_8).asScala 

And to write a sequence of lines into a file:

val strs = Seq("line1", "line2", "line3") Files.write(Paths.get("output_file"), strs.mkString("\n").getBytes())
