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: The C3 programming language reaches feature-stabiliy
C3, "The C-like for people who like C" just reached v0.5, marking its feature-stable release: https://c3.handmade.network/blog/p/8824-say_hello_to_c3_0.5
Feature stability ensures that version 0.5 will undergo bug fixes and maintenance separately from the main branch, providing projects with a stable compiler version to work with.
Try it out in the browser https://learn-c3.org
Github: https://github.com/c3lang/c3c
If you appreciate C, then maybe this is a language you'll enjoy. Dive into the documentation at https://c3-lang.org to view examples and read more in depth about the language.

Give me your feature ideas for a C-like
Tuples are being discussed, although I am unsure if it would be sufficiently useful. (Discussion here and here if you want to leave some thoughts)

Is there a static version of lld available? Or do I have to build lld from scratch?
I've been trying to build c3lang on my local machine. The problem is that it requires static files for both llvm and lld. Now, the static files for llvm have been provided (llvm-static), but not for lld, at least that's what I think. I thought that maybe I've made a mistake somewhere by not search the package thoroughly. I just wanted to know what package will install static files for lld.

Give me your best (and worst) ideas for a C-like language
So (preferably) have a little look at the language (https://c3-lang.org/) and maybe try it out (https://learn-c3.org/) and then file whatever issue you want: https://github.com/c3lang/c3c/issues/new

C3 is now at 0.4.0

Learn Enough C to Survive
> I wish we had C+: C + a few niceties (and not C ++ everything). There's a whole bunch of newer languages aiming at the space C is sitting in, but with a few additions C could be much more ergonomic without having to invent an entire new language.
I’ve made a pre-processor for C to add some things I miss, although it is currently limited to what can be done without type information and has to keep compatibility with existing C syntax: https://sentido-labs.com/en/library/cedro/202106171400/
There is another language call C3 that “is a C-like language striving to be an evolution of C, rather than a completely new language”: https://github.com/c3lang/c3c
If you have the time, I’d like to hear which things you miss in C. There might be something I did not imagine that could be added to Cedro.

Are Hoistings Possible for C++?
Off the top of my head, cc99 and c3 are two C dialects that both can do this.

Future of high-level languages
Sum types and pattern matching have already been hacked together in a preprocessor macro in C; see https://github.com/Hirrolot/datatype99.
- So far there is no evidence that Rust adds any value here. And if C is missing certain features, they can be added.
-
Does C have an equivalent to an algebraic data type?
It does not. There are people who have implemented such constructs in C code however, for example: https://github.com/Hirrolot/datatype99
-
Memory Management Reference
Nice reference but with some strange bits:
> Algebraic data types are usually represented using a heap. Because of their non-uniformity, algebraic data types are more difficult to scan.
Using a heap??? We can represent ADTs using stack as well, that's what we usually do in C and Rust.
Shameless plug: https://github.com/Hirrolot/datatype99 (a library of mine that generates type-safe ADTs for pure C99).

Pretty-Printable Enumerations in Pure C
I agree; I would especially not recommend abusing macros throughout an application codebase too much. Conceptually, Metalang99 is more of a (sub)language than a library, which also adds some entry barrier. Ideally, I see the application of Metalang99 being used "behind the scenes", e.g., encapsulated in separate code files/libraries such as Datatype99 and Interface99. This is what I (mostly) do in SmolRTSP.

lipstick: a Rust-like syntax frontend for C
I've done something similar with Datatype99 and Interface99. They are like a macro eDSL that compiles to C. The first one features algebraic data types, the second one features interfaces.
-
Any alternative to vala?
If you need a bit more high-level constructions, you can use the Datatype99 and Interface99 libraries. The former provides polymorphism over data, the latter -- over behaviour (I am the creator of these libraries).
-
Syntatic Sugar that compiles to C
OP, you might find datatype99 and its sibling projects interesting, though they mostly leverage the C preprocessor without going all the way towards defining a new language.
-
AST Implementation in C
You can use Datatype99 to represent your AST tagged union conveniently.

Rust for Linux Redux
Compared to plain C, you have ADTs which help from day to day programming. You can bring them to C (https://github.com/Hirrolot/datatype99) but I don't know if the Linux guys would allow it.
What are some alternatives?
