Author: arphaman Date: Thu Jan 24 15:07:58 2019 New Revision: 352125 URL: http://llvm.org/viewvc/llvm-project?rev=352125&view=rev Log: [clang-format] square parens with one token are not Objective-C message sends
The commit r322690 introduced support for ObjC detection in header files. Unfortunately some C headers that use designated initializers are now incorrectly detected as Objective-C. This commit fixes it by ensuring that `[ token ]` is not annotated as an Objective-C message send. rdar://45504376 Differential Revision: https://reviews.llvm.org/D56226 Modified: cfe/trunk/lib/Format/TokenAnnotator.cpp cfe/trunk/unittests/Format/FormatTestObjC.cpp Modified: cfe/trunk/lib/Format/TokenAnnotator.cpp URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Format/TokenAnnotator.cpp?rev=352125&r1=352124&r2=352125&view=diff ============================================================================== --- cfe/trunk/lib/Format/TokenAnnotator.cpp (original) +++ cfe/trunk/lib/Format/TokenAnnotator.cpp Thu Jan 24 15:07:58 2019 @@ -494,9 +494,14 @@ private: if (CurrentToken->is(tok::r_square)) { if (IsCpp11AttributeSpecifier) CurrentToken->Type = TT_AttributeSquare; - else if (CurrentToken->Next && CurrentToken->Next->is(tok::l_paren) && + else if (((CurrentToken->Next && + CurrentToken->Next->is(tok::l_paren)) || + (CurrentToken->Previous && + CurrentToken->Previous->Previous == Left)) && Left->is(TT_ObjCMethodExpr)) { - // An ObjC method call is rarely followed by an open parenthesis. + // An ObjC method call is rarely followed by an open parenthesis.
