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.

Strings In C Tiring And Unsafe So I Just Made
I didn't know about SDS. I wrote this https://github.com/NJdevPro/SPString about 15 years ago though for an embedded electronic project.

Strings in C... tiring and unsafe. So I just made this lib. Am I doing it right, Reddit ?
I've developped my own string library 15 years ago and used it in payment terminals with rather limited memory. if you are so concerned with string size, 2 bytes is enough for 65535 characters, which is enough for nearly everything. You are never going to allocate 8 bytes/string, that's stupid. If you need to work on more than that (a text editor for instance) you are not going to use C strings anyway, but some more complicated data structure. If you think adding 2 bytes per string is a problem, you probably are optimizing the wrong way. Pascal strings have been used since the 1970s and AFAIK have never been a problem memory-wise. And that's normal since they took exactly the same size as C strings.

Common libraries and data structures for C
I may as well throw my hat into the ring: https://github.com/lelanthran/libds
I decided that I wanted to be able to simply drop a single .h file and a single .c file into any project without have to build a `libBlah.so` and link it to every project that needed (for example) a hashmap.
The practical result is that using the hashmap only requires me to copy the header and source files into the calling project.
It does build as a standalone library too, so you can link it if you want.
My primary reason for starting this is that I was pretty unsatisfied with all of the string libraries for C. When all I want to do is concatenate multiple strings together, I don't want to have to convert between `char ` and `struct stringtype ` everywhere.
The string functions are very useful as they all operate on the standard `char *` (nul-terminated) type.

That would be nice, then I wouldn't have to use non-standard stuff.
I made my own easy-to-incorporate-into-any-project library - https://github.com/lelanthran/libds - just copy the ds_*.h and ds_*.c into a project and you're good to go.
I'm not saying it will work for you, but it works for me.

> Is there a good string-manipulation C library?
You will have to define "good". My string library[1][2] is "good" for me because:
1. It's compatible with all the usual string functions (doesn't define a new type `string_t` or similar, uses existing `char `).
2. It does what I want: a) Works on multiple strings so repeated operations are easy, and b) Allocates as necessary so that the caller only has to free, and not calculate how much memory is needed beforehand.
The combination of the above means that many common* string operations that I want to do in my programs are both easy to do and easy to visually inspect for correctness in the caller.
Others will say that this is not good, because it still uses and exposes `char *`.

[2] Currently the only bug I know of is the quadratic runtime in many of the functions. I intend to fix this at some point.

As an example of an opaque pointer library, see https://github.com/lelanthran/libds/blob/v1.0.5/src/ds_ll.h - See line 7 for the typedef. - Lines 9, 10, 11 and 67, 68 and 69 for making it callable from C++.
What are some alternatives?
