From 0720157cd7d82db6c1efea615c2e78565b4ada0e Mon Sep 17 00:00:00 2001 From: Jason Zaugg Date: Tue, 2 Oct 2012 21:01:10 +0200 Subject: SI-6436 Handle ambiguous string processors Before, we got in an inifinite loop by chasing the error typed result of adaptToMemberWithArgs. One point of befuddlement remains: why did t6436 and t6436b behave differently before this change? --- test/files/neg/t6436.check | 10 ++++++++++ test/files/neg/t6436.scala | 9 +++++++++ test/files/neg/t6436b.check | 10 ++++++++++ test/files/neg/t6436b.scala | 9 +++++++++ 4 files changed, 38 insertions(+) create mode 100644 test/files/neg/t6436.check create mode 100644 test/files/neg/t6436.scala create mode 100644 test/files/neg/t6436b.check create mode 100644 test/files/neg/t6436b.scala (limited to 'test') diff --git a/test/files/neg/t6436.check b/test/files/neg/t6436.check new file mode 100644 index 0000000000..ecb28f9100 --- /dev/null +++ b/test/files/neg/t6436.check @@ -0,0 +1,10 @@ +t6436.scala:8: error: type mismatch; + found : StringContext + required: ?{def q: ?} +Note that implicit conversions are not applicable because they are ambiguous: + both method foo1 in object quasiquotes of type (ctx: StringContext)Object{def q: Nothing} + and method foo2 in object quasiquotes of type (ctx: StringContext)Object{def q: Nothing} + are possible conversion functions from StringContext to ?{def q: ?} + println(q"a") + ^ +one error found diff --git a/test/files/neg/t6436.scala b/test/files/neg/t6436.scala new file mode 100644 index 0000000000..2c40502538 --- /dev/null +++ b/test/files/neg/t6436.scala @@ -0,0 +1,9 @@ +object quasiquotes { + implicit def foo1(ctx: StringContext) = new { def q = ??? } + implicit def foo2(ctx: StringContext) = new { def q = ??? } +} + +object Test extends App { + import quasiquotes._ + println(q"a") +} diff --git a/test/files/neg/t6436b.check b/test/files/neg/t6436b.check new file mode 100644 index 0000000000..b3c2d73739 --- /dev/null +++ b/test/files/neg/t6436b.check @@ -0,0 +1,10 @@ +t6436b.scala:8: error: type mismatch; + found : StringContext + required: ?{def q: ?} +Note that implicit conversions are not applicable because they are ambiguous: + both method foo1 in object quasiquotes of type (ctx: StringContext)Object{def q: Nothing} + and method foo2 in object quasiquotes of type (ctx: StringContext)Object{def q: Nothing} + are possible conversion functions from StringContext to ?{def q: ?} + println(StringContext("a").q()) + ^ +one error found diff --git a/test/files/neg/t6436b.scala b/test/files/neg/t6436b.scala new file mode 100644 index 0000000000..8023329e90 --- /dev/null +++ b/test/files/neg/t6436b.scala @@ -0,0 +1,9 @@ +object quasiquotes { + implicit def foo1(ctx: StringContext) = new { def q = ??? } + implicit def foo2(ctx: StringContext) = new { def q = ??? } +} + +object Test extends App { + import quasiquotes._ + println(StringContext("a").q()) +} -- cgit v1.2.3
