tidy - modernize-make-shared — Extra Clang Tools 22.0.0git documentation (original) (raw)

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(new MyPair(1, 2));

// becomes

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

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

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

// becomes

my_ptr = std::make_shared(1, 2);

Options¶

MakeSmartPtrFunction¶

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

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

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.
