|
|
|
|
Header-only C++17 library provides nameof macros and functions to simply obtain the name of a variable, type, function, macro, and enum.
|
|
|
|
## Features
|
|
|
|
* C++17
|
|
* Header-only
|
|
* Dependency-free
|
|
* Compile-time
|
|
* Name of variable
|
|
* Name of type, variable type
|
|
* Name of member, pointer
|
|
* Name of function, member function
|
|
* Name of enum, enum variable, enum-flags
|
|
* Name of macro
|
|
|
|

## [Examples](example/example.cpp)
|
|
|
|
* Nameof
|
|
|
|
```cpp
|
|
// Name of variable.
|

|
|
|
// Name of member variable.
|
|
NAMEOF(person.address.zip_code) -> "zip_code"
|
|
|
|
// Name of function.
|
|
NAMEOF(foo<int, float>()) -> "foo"
|
|
|
|
// Name of member function.
|
|
NAMEOF(somevar.some_method()) -> "some_method"
|
|
NAMEOF(somevar.some_method<int>()) -> "some_method"
|
|
|
|
// Name of macro.
|
|
NAMEOF(__LINE__) -> "__LINE__"
|
|
NAMEOF(NAMEOF(structvar)) -> "NAMEOF"
|
|
|
|
// Obtains full name of variable, function, macro.
|
|
NAMEOF_FULL(somevar.some_method<int>()) -> "some_method<int>"
|
|
|
|
// Obtains raw name of variable, function, macro.
|
|
NAMEOF_RAW(somevar.some_method<int>()) -> "somevar.some_method<int>()"
|
|
```
|
|
|
|
* Nameof enum
|
|
|
|
```cpp
|
|
enum class Color { RED = 1, BLUE = 2, GREEN = 4 };
|
|
|
|
auto color = Color::RED;
|
|
// Name of enum variable.
|
|
NAMEOF_ENUM(color) -> "RED"
|
|
nameof::nameof_enum(color) -> "RED"
|
|
|
|
// Static storage enum variable to string.
|
|
// This version is much lighter on the compile times and is not restricted to the enum_range limitation.
|
|
NAMEOF_ENUM_CONST(Color::GREEN) -> "GREEN"
|
|
nameof::nameof_enum<Color::GREEN>() -> "GREEN"
|
|
|
|
// Enum flags variable to string.
|
|
NAMEOF_ENUM_FLAG(Color::GREEN | Color::BLUE) -> "GREEN|BLUE"
|
|
nameof::nameof_enum_flag<Color::GREEN>() -> "GREEN|BLUE"
|
|
|
|
// Obtains name of enum variable or default value if enum variable out of range.
|
|
NAMEOF_ENUM_OR(Color::GREEN) -> "GREEN"
|
|
NAMEOF_ENUM_OR((Color)0, "none") -> "none"
|
|
```
|
|
|
|
* Nameof type
|
|
|
|
```cpp
|
|
const my::detail::SomeClass<int>& var_ref = var;
|
|
// Name of variable type.
|
|
NAMEOF_TYPE_EXPR(var_ref) -> "my::detail::SomeClass<int>"
|
|
nameof::nameof_type<decltype(var_ref)>() -> "my::detail::SomeClass<int>"

|
|
nameof::nameof_short_type<decltype(var_ref)>() -> "SomeClass"
|
|
|
|

|
|

|
|
NAMEOF_FULL_TYPE_RTTI(*ptr) -> "volatile const my::detail::Derived&"
|
|

|
|
|
|
struct A {
|
|

|
|
nameof::nameof_member(&A::this_is_the_name) -> "this_is_the_name"
|
|
|

## Remarks
|
|
|
|
* Before use, read the [limitations](doc/limitations.md) of functionality.
|
|
|
|
## Integration
|
|
|
|
You should add required file [nameof.hpp](include/nameof.hpp).
|
|
|
|
If you are using [vcpkg](https://github.com/Microsoft/vcpkg/) on your project for external dependencies, then you can use the [nameof package](https://github.com/microsoft/vcpkg/tree/master/ports/nameof).
|
|
|
|
If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add `nameof/x.y.z` to your conan's requires, where `x.y.z` is the release version you want to use.
|
|
|
|
Archlinux users can install `nameof` by package manager AUR, using the following command: `yay -S nameof`.
|
|
|
|
Alternatively, you can use something like [CPM](https://github.com/TheLartians/CPM) which is based on CMake's `Fetch_Content` module.
|
|
|
|
```cmake
|
|
CPMAddPackage(
|
|
NAME nameof
|
|
GITHUB_REPOSITORY Neargye/nameof
|
|
GIT_TAG x.y.z # Where `x.y.z` is the release version you want to use.
|
|
)
|
|
```
|
|
|
