Very happy to share that a new package rspdlite arrived on CRAN today in its inaugural version 0.1.0-1. It wraps and provides the (header-only) C++20 library spdlite which its author describes (aptly) as tiny, fast, capable. Just like its bigger sibbling spdlog (which we wrapped as rcppspdlog), it is written by Gabi Melman. However, with a focus on C++20 and compile-time configuration, it is lighter, nimbler and faster. It is also still a fairly young project so changes may occur.
I have been working on this for about a month, and it is ready for use by R and C++. It contains the initial upstream release 0.1.0, and I plan to follow the upstream versioning making this first release as 0.1.0-1.
The package itself provides the headers for use from other C++ projects (i.e. mostly other packages), as well as a simple R wrapper so that logging can occur from either C++ or R. It will generally access the single logger instance in a compilation unit. So for a package built against these header it would be shared library of that package. At present we provide the basic logging level setters and getters, formatting accessors, and two (compile-time) options of a ‘null logger’ and a file-based logger. More options are availble from the C++ level, multiple logging sinks are but one example. Some examples are provided in the package as an R example and a C++ example; these are probably best examined from the sources.
The NEWS entry for this release is simply and just announces that we have a release. More details are in the ChangeLog and the GitHub repo.
