awesome-hpp VS mp-units

awesome-hpp. A curated list of awesome header-only C++ libraries.

I sampled ten arbitrary projects from https://github.com/p-ranav/awesome-hpp, and not one of them used this pattern. Maybe it's more common in some circles than others?

If package managers seem intimidating, try header-only libraries that require no compilation or configuration.

That doesn't mean there aren't any header-only libraries. Usually small libraries implement everything in a header file. Checkout this GitHub link. With such header-only-libraries, all you have to do is include the header, write code which uses them, compile and you are done. This also doesn't involve the headache of setting up complicated build systems.

It's not the type system you're complaining about, though. It takes a bit of work but you can write types that include units information with no loss of performance.

I recommend using this as reference https://github.com/mpusz/units it probably solves the same or similar problem.

Yep. And there are some libraries to provide strong-type int, depending on what you need: type_safe or even units.

Indeed you cannot. Then again, you couldn't write a library like fmtlib in C in the first place. I mean why do you complain about C++ features which enable you to write libraries you otherwise couldn't? How would you expect to implement equivalent libraries to EVE or mp-units in C alone?

How does it compare with https://github.com/mpusz/units ?

I don't have a book to recommend, but I have a fantastic library: https://github.com/mpusz/units

Good C++ library for that topic is [0]. You can even go further and combine with something like [1] which is super helpful for kalman filters and other stuff where you have heterogeneous units in one vector.

This seems to be on a progress to standardisation for c++23/26: https://github.com/mpusz/units
