[PATCH] D147377: [clang-format] Don't allow variable decls to have trailing return arrows

[Owen Pan via Phabricator via cfe-commits]

owenpan added inline comments.


================
Comment at: clang/lib/Format/TokenAnnotator.cpp:1922
     } else if (Current.is(tok::arrow) && AutoFound &&
                (Line.MustBeDeclaration || Line.InPPDirective) &&
                Current.NestingLevel == 0 &&
----------------
It seems we can simply check if the line might be a function declaration here instead of resetting `AutoFound` below.


================
Comment at: clang/unittests/Format/TokenAnnotatorTest.cpp:1493
+
+  Tokens = annotate("auto foo() -> auto { return Val; }");
+  ASSERT_EQ(Tokens.size(), 12u) << Tokens;
----------------
Can this be valid C++?
