Providing logging details with source_location
Debugging is an essential part of software development. No matter how simple or complex it is, no program works as intended from the first shot. Therefore, developers spend a considerable amount of time debugging their code, employing various tools and techniques from debuggers to messages printed to a console or a text file. Sometimes, we want to provide detailed information about the source of a message in a log, including the file, the line, and maybe the function name.
