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``.
.. code-block:: c++
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``.
.. code-block:: c++
my_ptr.reset(new MyPair(1, 2));
// becomes
my_ptr = std::make_shared<MyPair>(1, 2);
Options
-------
.. option:: MakeSmartPtrFunction
A string specifying the name of make-shared-ptr function. Default is
`std::make_shared`.
.. option:: MakeSmartPtrFunctionHeader
A string specifying the corresponding header of make-shared-ptr function.
Default is `memory`.
.. option:: IncludeStyle
A string specifying which include-style is used, `llvm` or `google`. Default
is `llvm`.
.. option:: IgnoreMacros
If set to `true`, the check will not give warnings inside macros. Default
is `true`.
.. option:: 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`.
