Log output format

[Novazhangquan]

Spdlog uses the {} placeholder syntax of the fmt library. Now I want to use C-style formatting tags ( %d, %s, %c). What should I do?

Duplicate #1843

By the way, the fmt library is the original library of std::format.
The purpose of std::format is to provide a better API than printf which creates bugs.

Can I understand that spdlog cannot output printf-style logs by modifying the configuration? @tt4g

Yes. spdlog does not support printf style.
You can use wrapper macro: #1843 (comment)
