modernize-make-shared

This check finds the creation of std::shared_ptr objects by explicitly calling the constructor and a new expression, and replaces it with a call to std::make_shared.

auto my_ptr = std::shared_ptr<MyPair>(new MyPair(1, 2));

// becomes

auto my_ptr = std::make_shared<MyPair>(1, 2);

This check also finds calls to std::shared_ptr::reset() with a new expression, and replaces it with a call to std::make_shared.

my_ptr.reset(new MyPair(1, 2));

// becomes

my_ptr = std::make_shared<MyPair>(1, 2);

Options

MakeSmartPtrFunction

A string specifying the name of make-shared-ptr function. Default is std::make_shared.

MakeSmartPtrFunctionHeader

A string specifying the corresponding header of make-shared-ptr function. Default is memory.

IncludeStyle

A string specifying which include-style is used, llvm or google. Default is llvm.

IgnoreMacros

If set to true, the check will not give warnings inside macros. Default is true.

IgnoreDefaultInitialization

If set to non-zero, the check does not suggest edits that will transform default initialization into value initialization, as this can cause performance regressions. Default is 1.
