[cpp] use {fmt} library

[ImanSeyed]

Instead of using plain C functions, we can use the {fmt} library. Currently, there's no implementation of std::format(), so we have to use {fmt} instead. It's a more C++-ish thing to do.

That does look pretty nice :O I've not used fmt before and don't know how widely installed it is, but if it builds on github and builds on my laptop, then I'll go ahead and merge :)

(It's coming up to 2am here though, so probably after sleeping ^^;; )

Looks like fmt is a third-party library, so it needs adding to the list of dependencies to install before building?

Yes.

For Ubuntu I think this is fmtlib-dev, for nixpkgs it's fmt.

Needs to be added here (apt packages): https://github.com/shish/rosettaboy/blob/b12ea45743ea844eb9a2e7697455ff516fe6d632/.github/workflows/cpp.yml#L23

And here (nixpkgs): https://github.com/shish/rosettaboy/blob/b12ea45743ea844eb9a2e7697455ff516fe6d632/cpp/shell.nix#L2-L6

Done.

Alright, I think we're all set. Looks like I had to use something called "header-only" mode to fix the linking of the {fmt} library according to this. Also, the package name for Ubuntu was libfmt-dev, my bad.

Success \o/ Merging now, thank you <3
