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.

Common libraries and data structures for C
Can someone tell me what is this line from sc_signal.c:247 in sc/signal/
If the way it is used requires the user to break the abstraction/encapsulation and manually buffer some fields in order not to break the data structure and leak memory, I would call that a bug.
There is one use of sc_array_clear() in the test code [1] which really makes it look as if it is being used in a way that I think (again, I haven't single-stepped this code, only read it) leaks memory.
I agree on the pain of everything being macros, it's more pain than it's worth I think and will likely lead to code duplication (and more pain in debugging, probably).
I would even go so far as to think that this kind of single-file design, where each file is independent of the others, makes it harder and more annoying to implement more complicated data structures.

For those who are interested in faster hashmaps, I tried bunch of hashmaps and this one performs better than others. This is for C. Maybe C++ has better hashmaps.

How to implement a hash table (in C)
You skipped hs_remove but depending on implementation, hs_remove strategy may change your hs_set, e.g using tombstones. I’ve recently learnt that you don’t need tombstones at all in linear hashmaps, you just do backshift removals, it may be a simple addition to your map. Check out these repos for the implementation :
