Description

C++ header file with inline implementations for the µTest++ reflection utilities.

This header provides the inline implementations for the reflection utilities used within the µTest++ framework. It includes the logic for capturing and reporting source location information, such as file names and line numbers, as well as utilities for extracting type names at compile time using compiler-specific macros.

The source_location implementation offers a lightweight, constexpr-compatible alternative to std::source_location, enabling enhanced diagnostics and reporting even in environments lacking C++20 support. The type_name utility leverages compiler intrinsics to obtain human-readable type names for improved test output and debugging.

All definitions reside within the micro_os_plus::micro_test_plus::reflection namespace, ensuring clear separation from user code and minimising the risk of naming conflicts.

The header files are organised within the include/micro-os-plus/micro-test-plus folder to maintain a structured and modular codebase.

This file is intended solely for internal use within the framework and should not be included directly by user code.

Functions

type_name()

template <class T>

std::string_view micro_os_plus::micro_test_plus::reflection::type_name (void)

nodiscardconstexpr

Extract the type name from the __PRETTY_FUNCTION__ macro.

This function template parses the compiler-specific __PRETTY_FUNCTION__ macro to extract a concise type name for the template parameter T.

The implementation is compiler-dependent and may require adjustment for different toolchains. It is primarily intended for internal use within the µTest++ framework to support improved diagnostics and reporting.

Template Parameters

T	The type whose name is to be extracted.

Parameters

None.

Returns

A std::string_view containing the extracted type name.

Definition at line 133 of file reflection-inlines.h.
