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.

Object-oriented Programming with ANSI-C [pdf]
Where cloak.h is https://github.com/pfultz2/Cloak/blob/master/cloak.h
The above macros are admitttedly very hairy. If C had a better preprocessor, but was otherwise unchanged, they could look a lot nicer.
> I never said such a thing. Would appreciate if you didn't put words in my mouth.
A normal part of dialogue is, "I'm going to repeat your point back to you in my own words, and you can either agree with my restating of it, or point out at which point I've misunderstood you". That's what I was doing. "Would appreciate if you didn't put words in my mouth" is unnecessary hostility.
> In my concrete example, given that FILE and DIR were classified as objects, to which of the so-called objects does F(const char*, FILE, DIR) belong?
Take any language which you agree is "OO". Add one new feature (if it isn't already there): functions/methods which don't belong to any class/object. Now the function you are talking about is possible in that language. Did the language thereby suddenly cease to be OO when we added that feature? Most people would disagree with "Yes". But if "No", what is the actual difference between C and that language?

Plain C API design, the real world Kobayashi Maru test
> I use this pattern so much I actually wrote a little metaprogramming language that is capable of generating a lot of the boilerplate for you. Link in my bio, if anyone's interested in looking at it.
Your language [0] is an interesting idea. I've done a lot of similar stuff (not at work, I'm very rarely asked to write C code professionally, but I like mucking around with it in my personal time). My own approach to C metaprogramming involves obtuse preprocessor hacks (e.g [1]) and shell scripts that use grep/awk/sed to find macro invocations and spit out new header files as a result. Maybe your way is better.
A word of warning though – do you realise your name for your language is an anti-gay slur in several dialects of English? You might end up unintentionally upsetting some people with it.

Datatype99: C99 with Sum Types, v0.1.0
Well, mostly I use idioms from the Cloak Wiki (https://github.com/pfultz2/Cloak/wiki/C-Preprocessor-tricks,...). It takes some time to realise them :)

There is a project that achieves something like this, and quite nicely I think, worth checking it https://github.com/Hirrolot/interface99

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.

Comparing Golang and Interface99
There are also some differences. Golang, for example, can resolve interface methods at run-time, whereas Interface99 constructs virtual tables statically. Interface99 allows default implementations; Golang doesn't. And, of course, Interface99 mandates placing impl(MyIface, MyType), whereas Golang uses a.k.a. duck typing for interfaces (interface implementations are indistinguishable from ordinary methods). Also, when you would use embedding in Golang, such as this:
I think your github repo link is broken. Here's a working link.

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).

Is it possible that you could benefit from "a better C"? If so, I'd love to hear your take on Crystal, and the recent announce on Interface99.
