Limitations

Nameof

If argument does not have name, occurs the compilation error "Expression does not have a name.".

Nameof Type

This library uses a compiler-specific hack (based on __PRETTY_FUNCTION__ / __FUNCSIG__).
nameof_type and nameof_type_rtti returns compiler-specific type name.
To check is nameof_type supported compiler use macro NAMEOF_TYPE_SUPPORTED or constexpr constant nameof::is_nameof_type_supported.
If nameof_type used on unsupported compiler, occurs the compilation error. To suppress error define macro NAMEOF_TYPE_NO_CHECK_SUPPORT.
To check is nameof_type_rtti supported compiler use macro NAMEOF_TYPE_RTTI_SUPPORTED or constexpr constant nameof::is_nameof_type_rtti_supported.
If nameof_type used on unsupported compiler, occurs the compilation error. To suppress error define macro NAMEOF_TYPE_NO_CHECK_SUPPORT.

Nameof Enum

This library uses a compiler-specific hack (based on __PRETTY_FUNCTION__ / __FUNCSIG__), which works on Clang >= 5, MSVC >= 15.3 and GCC >= 9.
Do not use nameof and magic_enum in the same project to get enum name.
To check is nameof_enum supported compiler use macro NAMEOF_ENUM_SUPPORTED or constexpr constant nameof::is_nameof_enum_supported.
If nameof_enum used on unsupported compiler, occurs the compilation error. To suppress error define macro NAMEOF_ENUM_NO_CHECK_SUPPORT.
Enum value must be in range [NAMEOF_ENUM_RANGE_MIN, NAMEOF_ENUM_RANGE_MAX].
- By default NAMEOF_ENUM_RANGE_MIN = -128, NAMEOF_ENUM_RANGE_MAX = 128.
- NAMEOF_ENUM_RANGE_MIN must be less or equals than 0 and must be greater than INT16_MIN.
- NAMEOF_ENUM_RANGE_MAX must be greater than 0 and must be less than INT16_MAX.
- If need another range for all enum types by default, redefine the macro NAMEOF_ENUM_RANGE_MIN and NAMEOF_ENUM_RANGE_MAX.
```
#define NAMEOF_ENUM_RANGE_MIN 0
#define NAMEOF_ENUM_RANGE_MAX 256
#include <nameof.hpp>
```
- If need another range for specific enum type, add specialization enum_range for necessary enum type. Specialization of enum_range must be injected in namespace nameof::customize.
```
#include <nameof.hpp>

enum class number { one = 100, two = 200, three = 300 };

template <>
struct nameof::customize::enum_range<number> {
  static constexpr int min = 100;
  static constexpr int max = 300;
};
```
Won't work if a value is aliased, work with enum-aliases is compiler-implementation-defined.
Won't work if the enum is a forward declaration.
Intellisense Visual Studio may have some problems analyzing nameof.
