From d76dc724e319663b6f854ecade8524323a576ea8 Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Fri, 27 May 2011 00:10:39 +0000 Subject: Overcoming limitations of the repl, multiple-tr... Overcoming limitations of the repl, multiple-tree lines and assignments. The best part of nicely documented limitations is that you can stare at the same comment for years and then the day comes when you give it the heave-ho. Exhibit A (regarding a single bare expression): "This is necessary due to it being hard to modify code at a textual level, and it being hard to submit an AST to the compiler." Yes, it IS hard to modify code at a textual level (see enclosed patch) but we won't let that stop us anymore. Closes #4578. Exhibit B (regarding the left hand side of assignments having to be Ident): "An unfortunate limitation." Unfortunate no longer! No review. --- test/files/run/repl-bare-expr.check | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 test/files/run/repl-bare-expr.check (limited to 'test/files/run/repl-bare-expr.check') diff --git a/test/files/run/repl-bare-expr.check b/test/files/run/repl-bare-expr.check new file mode 100644 index 0000000000..04daa48232 --- /dev/null +++ b/test/files/run/repl-bare-expr.check @@ -0,0 +1,36 @@ +Type in expressions to have them evaluated. +Type :help for more information. + +scala> + +scala> 2 ; 3 +res0: Int = 3 + +scala> { 2 ; 3 } +res1: Int = 3 + +scala> 5 ; 10 ; case object Cow ; 20 ; class Moo { override def toString = "Moooooo" } ; 30 ; def bippy = { + 1 + + 2 + + 3 } ; bippy+88+11 +defined module Cow +defined class Moo +bippy: Int +res2: Int = 105 + +scala> + +scala> object Bovine { var x: List[_] = null } ; case class Ruminant(x: Int) ; bippy * bippy * bippy +defined module Bovine +defined class Ruminant +res3: Int = 216 + +scala> Bovine.x = List(Ruminant(5), Cow, new Moo) +Bovine.x: List[Any] = List(Ruminant(5), Cow, Moooooo) + +scala> Bovine.x +res4: List[Any] = List(Ruminant(5), Cow, Moooooo) + +scala> + +scala> -- cgit v1.2.3
