Static Public Member Functions
static constexpr source_location	current (const char *file="unknown", unsigned int line={}) noexcept
	Obtain the current source location.

Private Attributes
const char *	file_ { "unknown" }
	The file name where the source location was captured.
unsigned int	line_ {}

Detailed Description

This class provides a lightweight, constexpr-compatible alternative to std::source_location for environments lacking C++20 standard support.

It enables retrieval of the file name and line number at the point of invocation, supporting enhanced diagnostics and reporting within the µTest++ framework.

The static current() method captures the current source location, using compiler built-ins where available, or defaulting to "unknown" and zero otherwise.

current()

source_location micro_os_plus::micro_test_plus::reflection::source_location::current ( const char * file = "unknown", unsigned int line = {} )

staticnodiscardconstexprnoexcept

Parameters

file	The file name (automatically provided by the compiler).
line	The line number (automatically provided by the compiler).

Returns

A source_location instance with the captured information.

Returns a source_location instance representing the file name and line number at the point of invocation.

If supported by the compiler, uses built-in macros to capture this information; otherwise, defaults to "unknown" and zero.

      source_location sl{};
      sl.file_ = file;
      sl.line_ = line;
