Description​

Local implementation of source location information for diagnostics.

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.

Public Static Functions​

current()​

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

Obtain the current source location.

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.
