show file and line number on global logger

[thewh1teagle]

Hi!

I would like to show filename and line number in the global logger.
I tried to use the macros like

SPDLOG_DEBUG(...)

but seems like it depends on constant static level defined with #define otherwise it's not print anything (also I can't change it?). However I would like to simply use:

spdlog::debug(...)

And it will show line numbers.

If it's not possible and it's possible only when specifying the logger, should I declare the logger statically in some header file and use it directly eg.

spdlog::debug(g_logger, ...)

TLDR of what I'm looking for:

int main() {
  spdlog::cfg::load_env_levels();
  spdlog::debug("hello");
  return 0;
}
./app
DEBUG main.cpp:2: hello

The project for repo: loud.cpp

The logging macro was originally introduced as a feature to remove unnecessary log output at compile time: https://github.com/gabime/spdlog/wiki/0.-FAQ#how-to-remove-all-debug-statements-at-compile-time-

Replace all logging statements with logging macros and define #define SPDLOG_ACTIVE_LEVEL SPDLOG_LEVEL_TRACE macro (before using spdlog) so that logging macros are not removed.
