Idiomatic IO with scala

Question

In java, common IO operations involving streams, files and the like can be somewhat annoying. Thus I (and many others) tend to reach for things like commons-io to ease the pain.

In scala - are there some better idioms/classes/libraries to use (I know of scala.io.Source etc for reading in text files - but what about streams etc). Is it "normal" to use libraries like commons-io in scala or is there a much better way?

Answer 1

What about using:

Source.fromInputStream(is, "UTF8")

As in:

for (line <- Source.fromInputStream(is, "UTF8").getLines) {
   // process line here
}

Answer 2

There were some discussions on the Scala mailing list on this particular matter. And, if I recall correctly, nothing concrete came out of them. In the mean time, you won't be at a loss to check out Scalax. scalax.io looks very promising.

Answer 3

I/O hasn't been addressed as yet in Scala. What exists, exists solely to support the compiler and the XML library.

Answer 4

Erik Engbrecht's scalax fork might be useful.
