Examples

Reading & Writing Files

Just reading from a file

 val lines = scala.io.Source.fromFile("myfile.txt").mkString // leaves the file open

 import scala.io.Source._ ;

 // slurp the file
 val source1 = fromFile("myfile.txt", "utf-8") ;
 val lines = source1.getLines mkString "\n" ;
 source1.close() ; // good practice

 // or create an iterator
 val source2 = fromFile("myfile.txt", "utf-8")
 source2.foreach{
    print 
 }

 // tab separated file
 val source3 = fromFile("myfile.tsv", "utf-8")
 source3.foreach {
    print _.toArray ;
 } 
 source3.close ;
