I am completely unfamiliar with this project but I am a native English speaker, hopefully I understood the original document and my proposed changes improve the grammar without changing the meaning.

# Limitations
|
|
|
|
## Nameof
|
|
|
|
* If the argument does not have a name, the compilation error `"Expression does not have a name."` occurs.
|
|
|
|
## Nameof Type
|
|
|
|
* This library uses a compiler-specific hack (based on `__PRETTY_FUNCTION__` / `__FUNCSIG__`).
|
|
|
|
* nameof_type and nameof_type_rtti return a compiler-specific type name.
|
|
|
|
* To check if nameof_type is supported by your compiler use the macro `NAMEOF_TYPE_SUPPORTED` or constexpr constant `nameof::is_nameof_type_supported`.</br>
|
|
If nameof_type is used on an unsupported compiler, a compilation error occurs. To suppress the error define the macro `NAMEOF_TYPE_NO_CHECK_SUPPORT`.
|
|
|
|
* To check if nameof_type_rtti is supported by your compiler use macro `NAMEOF_TYPE_RTTI_SUPPORTED` or constexpr constant `nameof::is_nameof_type_rtti_supported`.</br>
|
|
If nameof_type_rtti is used on an unsupported compiler, a compilation error occurs. To suppress the error define the 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](https://github.com/Neargye/nameof) and [magic_enum](https://github.com/Neargye/magic_enum) in the same project to get enum name.
|
|
|
|
* To check if nameof_enum is supported by your compiler use the macro `NAMEOF_ENUM_SUPPORTED` or constexpr constant `nameof::is_nameof_enum_supported`.</br>
|
|
If nameof_enum is used on an unsupported compiler, a compilation error occurs. To suppress the error define the 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 than or equal to `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 another range is needed for all enum types by default, redefine the macro `NAMEOF_ENUM_RANGE_MIN` and `NAMEOF_ENUM_RANGE_MAX`.
|
|
|
|
```cpp
|
|
#define NAMEOF_ENUM_RANGE_MIN 0
|
|
#define NAMEOF_ENUM_RANGE_MAX 256
|
|
#include <nameof.hpp>
|
|
```
|
|
|
|
* If another range is needed for a specific enum type, add specialization `enum_range` for necessary enum type. Specialization of `enum_range` must be injected in `namespace nameof::customize`.
|
|
|
|
```cpp
|
|
#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, support for 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`.
