• Are Maybes a good pattern for scala?

  - by Fred Haslam

  For a while I have been struggling to integrate scala with java methods that might return null. I came up with the following utility which helps a lot: // produce an Option, nulls become None object Maybe { def apply[T](t:T) = if (t==null) None else Some(t) } Maybe(javaClass.getResultCouldBeNull()).map( result => doSomeWork(result) ) I have a few questions about this solution: Is there a better or more standard pattern to use? Am I duplicating something that already exists? Does this functionality have hidden gotchas?

  Is there any free Java library for extracting text from PDF, that is compatible with Google Application Engine? I've read about PDFJet, but it can't read PDF, can it?

• Parsing plain text to some structured object

  - by Jeriho

  I am working on parsing plain text and converting it to key-value pairs. For example, plain text: some_uninteresting_thing key1 valueA, valueB, valueC key2 valueD key3 valueE valueF key4 valueG(valueH, valueI) key5 some_uninteresting_thing valueJ some_uninteresting_thing key6 some_uninteresting_thing (key6 shouldn't be mapped because has no appropriate values) As you can see plain text is lenient. What java library can handle this? If no such library exist, any suggestions on algorithm to do this.

• What is the best way to use whitespace while programming?
