* Cull extraneous whitespace.Paul Phillips2013-09-181-2/+2
| | | | | | | | | | | | | | | | | | | | | One last flurry with the broom before I leave you slobs to code in your own filth. Eliminated all the trailing whitespace I could manage, with special prejudice reserved for the test cases which depended on the preservation of trailing whitespace. Was reminded I cannot figure out how to eliminate the trailing space on the "scala> " prompt in repl transcripts. At least reduced the number of such empty prompts by trimming transcript code on the way in. Routed ConsoleReporter's "printMessage" through a trailing whitespace stripping method which might help futureproof against the future of whitespace diseases. Deleted the up-to-40 lines of trailing whitespace found in various library files. It seems like only yesterday we performed whitespace surgery on the whole repo. Clearly it doesn't stick very well. I suggest it would work better to enforce a few requirements on the way in.
* Added -Xlog-implicit-conversions.Paul Phillips2012-01-021-0/+25
New command line option prints a message whenever the compiler inserts an implicit conversion. Implicit parameters are not under consideration here, since the primary motivation is to make it easy to inspect your code for unintentional conversions, since they can have dramatic performance implications. class A { def f(xs: Array[Byte]) = xs.size def g(xs: Array[Byte]) = xs.length } % scalac -Xlog-implicit-conversions logImplicits.scala logImplicits.scala:2: applied implicit conversion from xs.type to ?{val size: ?} = implicit def byteArrayOps(xs: Array[Byte]): scala.collection.mutable.ArrayOps[Byte] def f(xs: Array[Byte]) = xs.size ^
