Rendering problem in composeLens exercise

[FRosner]

Problem

The composeLens exercise does not get rendered correctly.

The source code:

  def exerciseComposeLens(res0: Int, res1: Person) = {

    (addressLens composeLens streetNumber).get(john) should be(res0)
    (addressLens composeLens streetNumber).set(2)(john) should be(res1)
  }

How it looks on the web page:

addressLens composeLens streetNumber).get(john) should be( )
    (addressLens composeLens streetNumber).set(2)(john) should be( )

The initial bracket is missing and the second line has an unintended indentation.

Maybe it is related to the empty line?

Hi - I took a look at this. It seems to be not to do with the empty line but actually to do with the round brackets. The issue is that for a statement starting with a round bracket the Scala tree parser is identifying the start as the character after the bracket. This means the MethodBodyReader is not working as it should. The indentation is a knock-on effect of this. This bug will only happen when there are two lines or more in a method, and will only affect the bracket of the first line and the indentation of all the others.

I have yet to think of a neat workaround, but will have a pop! I might also ask the Scala compiler/reflection people whether this should be considered a bug with that.
