tinyformat VS scnlib

printf has some pretty serious security implications. When I want more complicated text printing options than what is easy or terse in iostream then I use the tinyformat library.

The usual way I do I/O is via combining C++ stringstremas with either tinyformat or via an implementation of p0117 "variadic to_[basic_]string, depending on the particular need.

Haven't been able to make it work with MSVC 2012 (the earliest Windows-side compiler I need to support). I myself use tinyformat instead.

However, not all is lost. While there are libraries like {fmt} I don't pay attention to them because they are far away into The Future and unusable with my requirements (C++03 support at the earliest, work reasons). Most newfangled libs I've seen are intended for Compilers of the Future, for C++20/C++23 and the like, and with that among other reasons are not generic enough for me. Instead I just use tinyformat that lays on top of both and bridges them, not to mention the biggest sell that is rrtaining the POSIX style printf notation (why didn't {fmt} go with that is still a mystery to me).

scnlib (https://github.com/eliaskosunen/scnlib) scanf

Yeah, but parsing format strings in runtime induces an overhead, and doing it in compile time is not trivial, and I’m not sure ClearIO is worth the trouble, since it turns out scnlib exists.

The code is rather nice (in my biased opinion) and makes heavy use of a couple of libraries like scnlib and [Eigen](eigen.tuxfamily.org/). Some things could probably be more optimized but I mainly focused on conciseness. I hope this is useful and I can explain my thought process further if you have any questions.

I've found https://github.com/eliaskosunen/scnlib but haven't tested it. Maybe that suits your needs for 2.

I had a user enum like enum class Color {Red, Green, Blue}; that I wanted to add serialization support for. Following the docs (https://scnlib.readthedocs.io/), after some tweaks I arrived at the following:

Thanks for the comment, I made an issue tracking this: https://github.com/eliaskosunen/scnlib/issues/51

I am using some modern libraries: scnlib fmtlib Eigen and usually abuse lambdas :)
