From 40e7cab7a22a8531bdd310bfb57fda51b798c690 Mon Sep 17 00:00:00 2001 From: Lukas Rytz Date: Fri, 11 May 2012 16:00:54 +0200 Subject: Fix SI-5009: case-class copy method now eta-expands over higher parameter lists. Example: Given case class C(a: Int)(b: Int) if you call (new C(1)(2)).copy(a = 10)), you get a function (f: Int => C) such that (f.apply(20)) yields a (new C(10)(20)). --- test/files/run/names-defaults.check | 2 +- test/files/run/names-defaults.scala | 4 ++-- test/files/run/t5009.check | 4 ++++ test/files/run/t5009.scala | 17 +++++++++++++++++ 4 files changed, 24 insertions(+), 3 deletions(-) create mode 100644 test/files/run/t5009.check create mode 100644 test/files/run/t5009.scala (limited to 'test/files/run') diff --git a/test/files/run/names-defaults.check b/test/files/run/names-defaults.check index 5656d1a276..f253de71d6 100644 --- a/test/files/run/names-defaults.check +++ b/test/files/run/names-defaults.check @@ -92,7 +92,7 @@ test5 test5 5 10: 2 -slkdfj1 +slkdfj2 1 lskfdjlk 11 diff --git a/test/files/run/names-defaults.scala b/test/files/run/names-defaults.scala index e1bc7cbf59..220414f02a 100644 --- a/test/files/run/names-defaults.scala +++ b/test/files/run/names-defaults.scala @@ -176,7 +176,7 @@ object Test extends App { println(Fact2()("jyp")) println(Fact2(x = 1)()) - println(Fact2(10)().copy(y = "blabla")()) + println(Fact2(10)().copy(y = "blabla")(3)) // assignment to var <-> named argument @@ -195,7 +195,7 @@ object Test extends App { // dependent types and copy method val a11 = new A2 val b11 = a11.B2(new a11.C2)(1) - println(b11.copy()()) + println(b11.copy()(2)) diff --git a/test/files/run/t5009.check b/test/files/run/t5009.check new file mode 100644 index 0000000000..cc9df54b34 --- /dev/null +++ b/test/files/run/t5009.check @@ -0,0 +1,4 @@ +C(1,true) +10 +C(7283,20) +100 diff --git a/test/files/run/t5009.scala b/test/files/run/t5009.scala new file mode 100644 index 0000000000..b4fe1bc894 --- /dev/null +++ b/test/files/run/t5009.scala @@ -0,0 +1,17 @@ +object Test extends App { + + case class C[T, U <: String, O >: Object](x: Int, y: T)(z: U, b: Boolean)(s: O, val l: Int) + + val c = C(1, true)("dlkfj", true)("dlkfjlk", 10) + println(c) + println(c.l) + + val f1a = c.copy(y = 20, x = 7283) + + val f1b = c.copy[Int, String, Object](y = 20, x = 7283) + val f2b = f1b("lkdjen", false) + val res = f2b(new Object, 100) + println(res) + println(res.l) + +} -- cgit v1.2.3
