modernize-make-unique

This check finds the creation of std::unique_ptr objects by explicitly calling the constructor and a new expression, and replaces it with a call to std::make_unique, introduced in C++14.

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

// becomes

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

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

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

// becomes

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

Options

MakeSmartPtrFunction

A string specifying the name of make-unique-ptr function. Default is std::make_unique.

MakeSmartPtrFunctionHeader

A string specifying the corresponding header of make-unique-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 false, the check does not suggest edits that will transform default initialization into value initialization, as this can cause performance regressions. Default is true.
