modernize-use-using

The check converts the usage of typedef with using keyword.

Before:

typedef int variable;

class Class{};
typedef void (Class::* MyPtrType)() const;

typedef struct { int a; } R_t, *R_p;

After:

using variable = int;

class Class{};
using MyPtrType = void (Class::*)() const;

using R_t = struct { int a; };
using R_p = R_t*;

This check requires using C++11 or higher to run.

Options

IgnoreMacros

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