Functions
template<typename T>
constexpr bool	vlink::NameDetector::is_support () noexcept
	Checks at compile time whether the nameof library can produce a type name for T.
template<typename T>
constexpr std::string_view	vlink::NameDetector::get () noexcept
	Returns the unqualified compile-time name of type T as a std::string_view.
template<typename T>
std::string_view	vlink::NameDetector::get_enum (T e) noexcept
	Returns the string representation of an enumeration value e.

Detailed Description

Compile-time type-name and enum-name detection utilities.

The vlink::NameDetector namespace wraps the third-party nameof library to provide a portable, constexpr API for obtaining the string representation of a type or an enumeration value at compile time.

These utilities are used by the VLink plugin system to automatically derive plugin identifiers from interface class names, avoiding error-prone manual string registration.

Platform notes:

• On Windows (MSVC / MSYS2) the nameof library may prefix types with "struct " or "class ". NameDetector::get() strips these prefixes automatically to return only the unqualified type name.
• On GCC/Clang the result of nameof::nameof_type<T>() is used directly.

Note

The get<T>() function returns a constexpr std::string_view that points into static storage generated by the compiler. The view is valid for the entire program lifetime.

Example

// Check support and get the type name:
if constexpr (vlink::NameDetector::is_support<MyPlugin>()) {
  constexpr std::string_view name = vlink::NameDetector::get<MyPlugin>();
  // name == "MyPlugin"
}
 
// Get enum value name at runtime:
enum class Color { Red, Green, Blue };
std::string_view name = vlink::NameDetector::get_enum(Color::Green);
// name == "Green"
