Fail compile if AnyVal is inherited by a trait, a non-@inline class, or a class with an AnyRef parent somewhere. Added tests. Added logging, like [log extmethods] Inline class class Bippy spawns extension method. Old: def getClass: Class[_ <: Bippy] New: final def extension$getClass($this: Bippy): Class[_ <: Bippy] Fixed what I hope was a bug in ExtensionMethods where the original method params were dropped. Since adding a NonNull parent was also inflicting an AnyRef on AnyVal subclasses, suppressed that for those. Had the bright idea that AnyVal could extend NotNull. It doesn't seem to accomplish much, but then, I don't think NotNull accomplishes much. Still, maybe it's time to restrict the ways one can use AnyVal so one can't do this: scala> var x: AnyVal = _ x: AnyVal = null --- .../scala/reflect/internal/Definitions.scala | 8 ++++++-

For now it hides away in scala.tools.util.color. --- src/compiler/scala/tools/util/color/Ansi.scala | 58 ++ src/compiler/scala/tools/util/color/AnsiAtom.scala | 51 ++ src/compiler/scala/tools/util/color/CString.scala | 28 + .../scala/tools/util/color/ColorNames.scala | 391 ++++++++++++ src/compiler/scala/tools/util/color/package.scala | 21 + test/files/run/color.check | 693 +++++++++++++++++++++ test/files/run/color.scala | 33 + 7 files changed, 1275 insertions(+) create mode 100644 src/compiler/scala/tools/util/color/Ansi.scala create mode 100644 src/compiler/scala/tools/util/color/AnsiAtom.scala create mode 100644 src/compiler/scala/tools/util/color/CString.scala create mode 100644 src/compiler/scala/tools/util/color/ColorNames.scala create mode 100644 src/compiler/scala/tools/util/color/package.scala create mode 100644 test/files/run/color.check create mode 100644 test/files/run/color.scala diff --git a/src/compiler/scala/tools/util/color/Ansi.scala b/src/compiler/scala/tools/util/color/Ansi.scala new file mode 100644 index 0000000000..1ed43579bb --- /dev/null +++ b/src/compiler/scala/tools/util/color/Ansi.scala @@ -0,0 +1,58 @@ +/* NSC -- new Scala compiler + * Copyright 2005-2012 LAMP/EPFL + * @author Paul Phillips + */ + +package scala.tools.util +package color + +import collection.mutable + +object Ansi { + final val ESC = '\u001b' // + final val LBR = '\u005b' // [ + final val CSI = new String(Array(ESC, LBR)) // control sequence introducer + final val CSI_FINAL = "m" // control sequence final byte + + def colors = List(Black, Red, Green, Yellow, Blue, Magenta, Cyan, White) + def effects = List(Reset, Bright, Faint, Italic, Underline, Blink, Inverse, Hidden, Strikethrough) + + // No, that's not the finale of "CSI: Crime Scene Investigation." + + def colorizerFor(codes: Seq[Int]): String => String = + s => ansiCodeToString(codes) + s + ansiCodeToString(0) + + def ansiCodeToString(code: Int): String = CSI + code + CSI_FINAL + def ansiCodeToString(codes: Seq[Int]): String = codes.mkString(CSI, ";", CSI_FINAL) +} + +/** An ansi control sequence.
