rspdlite: Lightweight Logging From R and C++

Description

rspdlite relies on spdlite, a lightweight header-only C++20 library for logging. This package offers a simple and consistent interface from both R and C++.

Details

spdlite is the ‘little brother’ of spdlog (which we have available via R packages RcppSpdlog and spdl). spdlite is on purpose smaller and simpler. It has (by choice) fewer options and configuration settings keeping the core small and simple.

By using a global inline instance, each shared library (i.e. typically each package using logging) is guaranteed to have exactly one instance. So setting changes such as the logging level affect both the R and C++ side. If however another R package were to be compiled with the spdlite header, its instance would be separate as it resides in a different shared library. Similarly, an ad-hoc compilation via e.g. Rcpp::sourceCpp() will lead to a distinct instance for the same reason.
