I used yhirose's PEG (parsing expression grammar) libraryfor parsing.

What are some cool modern libraries you enjoy using?
By the same author, https://github.com/yhirose/cpp-peglib is also very nice.

A Good Tool for Resuming Parsers?
Most of the research into this sort of incremental and differential parsing unsurprisingly looks to be in the Haskell community, but I was hoping that someone here might know of some C++-friendly tools that might support generating parsers that support interruption and resuming. cpp-peglib looked really promising, but its parsers don't look like they can be engaged from any but the initial state.

How to convert an enum to string in C++
I really like better_enums instead of magic_enums. There’s no limit on enum size with it: http://aantron.github.io/better-enums/
It was heavily used at a former employer of mine, so definitely a solid production-ready solution.
-
What C++ library do you wish existed but hasn’t been created yet?
IIRC I then switched to another library doing the same stuff: https://github.com/aantron/better-enums It is not as magical, as it uses a special macro to define the enum, using dedicated syntax. So it only works for enums you yourself define. However, it did work a lot better for me with enums with huge values.

Behind the magic of magic_enum
I can't keep up! First we have better enum, then some guy at a conference says we have to use wise enum instead, and now you speak of magic enum!

let's all be chads
If you need a laugh today, look at Better Enums library for C++. If you thought moving from C to C++ would let you leave macros behind, think again! Enums in C++ still suck (a bit less than in C though), so someone built a library to help with that. And it's built on macros. So you can only have 64 entries per enum. And the library's code is barely readable.
