Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Matcheroni, a tiny C++20 header library for building lexers/parsers
Very cool, and I like the name!
I'd be interested in reading about how Matcheroni compares with PEGTL and Lexy.

Use PEGTL to remove my clunky homemade parser
I found a library I wanted to test: Pegtl

What are some cool modern libraries you enjoy using?
I like PEGTL

Are C/C++ developers allowed to import libraries to make coding easier or are they expected to build every functions and methods from scratch (without importing anything like String.h)?
Sure - libraries that are expected to be entirely self-contained. The one that comes to mind is PEGTL, a parser combinator library that is intended to be embedded inside a larger program. Making it import more dependencies would break this philosophy. Similarly, in the Rust world, there are a variety of "no-std" crates that should be able to be imported even if the standard library is not available on the target platform.

TIL: Visual Studio has quantum state values 🤨
The program in the post was just an example meant to illustrate the problem. Originally, this (new) behavior of MSVC broke my code in the PEGTL, see [this commit](https://github.com/taocpp/PEGTL/commit/e3c8cb499dc3d1d76d23f2d5d79469dcb15550c5) that I needed to apply to fix it.

We Built a C++ Rendering Engine for the Web
As a professional C++ programmer I feel a lot of the reasons C++ gets this response is because it's simply not "batteries included" like Go or Rust.
C++ is a very powerful, unopinionated language, that gives you a lot of freedom to attack your problem domain the way you best see fit.
If you're writing a networked application, don't use POSIX sockets, go and find a higher level library. If you're parsing complex text formats, don't iterate over buffers with char*'s, go pick up PEGTL[0]. If you're working on graphs, or need to properly index in-memory data, go pick up Boost[1][2]. If you need a GUI, go pick up Qt.
It's extremely common in C++, due to the lack of a universal package management solution, for people to try and "muddle through" and do shit themselves when it's far outside their core competency.
At one of my last employers, the core product was parsing JSON with std::regex, simply because they couldn't be bothered to integrate a JSON library.

Is there anything like sly for C++?
You are looking for Boost.Spirit (https://www.boost.org/doc/libs/1_76_0/libs/spirit/doc/x3/html/index.html) or PEGTL (https://github.com/taocpp/PEGTL)
-
Why no more Lex/Yakk/ANTLR/whatever?
I personally prefer to use parsing combinator libraries in C++, where the "grammar" is just part of normal C++ and directly integrate. Examples are Boost.Spirit, pegtl, or (my own) lexy.

Wondered if anyone is interested in a c++ parser combinators library?
While I'm not quite sure how this might transfer to your approach, with your Haskell-inspired style being quite different from our C++ templates, in the PEGTL our equivalent to your Char, which is called one, is variadic (true to the T in PEGTL a variadic template) and takes a list of possible matches.

Allegro library website redirected to anti-Kotaku Nazi-related page
Some nutjob has taken control of https://liballeg.org to redirect it to some anti-Nazi page that mentions Kotaku, comparing them to nazis.

Self taught developers, what did you know when you started?
C, C++, Allegro, SDL, Some rudimentary SQL, Some basic BSD Sockets. But I also took some time to learn 3D math, trigonometry and linear algebra so I can include some basic 3D examples in my portfolio. I was later told that it was the 3D math that made the difference because if I (barely finished HS) can do that I can probably learn everything they give me.

Recourses to make games like they did in the 90s?
Wow, DJGPP and Allegro (still going!), that takes me back - that and Bloodshed IDE were my weapons of choice back then!

Looking for a very basic 2d graphics library
allegro 5 is quite alright with fonts

What are some cool modern libraries you enjoy using?
allegro5 is a great rendering library if you want to get something 2D on the screen fast
-
Are there other examples of people who made games with their own engines like Minecraft ?
Hell, their website says in the first few sentences it isn't an engine.
-
Where to start?
A while ago I was getting started with the Allegro5 game engine (+Rust bindings). It's the same engine used for Factorio. I wrote a simple egui-integration to have nicer UI options. It was mostly for myself and is thus poorly documented but maybe you get some ideas how to make it work.
