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.

Writing portable C that uses pledge/unveil?
It looks like this is the same check for pledge/define HAVE_PLEDGE/guard the pledge invocation pattern is used in Brian Callahan's OpenED portable version of OpenBSD's ed(1).

Is there an editor like emacs, vim, etc. but (solely) used in the BSD world?
ed(1) on BSD is distinct from GNU ed (which broke some of my common usage patterns in version 1.14). However, it is portable so could be built on Linux if you want. :-)

Helix: Release 24.03 Highlights
Helix's modal editing is based on Kakoune's modal editing which is like an evolution to Vim's modal editing. You can think of it as being always in selection (visual) mode. https://github.com/mawww/kakoune?tab=readme-ov-file#selectio...

A tutorial for the Sam command language (1986) [pdf]
And while it doesn’t use the sam language precisely, I think in the broader “postfix Vi with visual feedback” category Kakoune[1] also warrants mentioning. The command language, in my experience, feels much more logical than that of Vis coming from a blank slate (things might be different if you come from Vim, but even when I used Vim regularly I never used the editing language that much exactly because I could never remember the damn thing).
And having mentioned Kakoune it’d probably be unfair to then not mention Helix[2]. It has a very similar editing language, but it’s a fairly anti-Unix everything-bolted-in affair on the inside (“everything works out of the box” being the advertising take) compared to Kakoune’s Acme-inspired no-scripting scripting (there’s an ex-style command to exec a user program that can then drive the editor over stdio RPC, a set of hooks, and that’s it). So if you’ve come for the Plan 9 feels, I don’t expect Helix to be that appealing. It’s still a good editor, nevertheless.

What is the best book for complete beginner?
You can take a look at kakoune. The source code (excluding documentations, test cases, customizations etc.) is less than 40k. It is, IMHO, a show case of a C++ project in use.

Yes.

Not very motivated for such a harsh critic..

Understanding the Origins and the Evolution of Vi and Vim
I've been using Vim for years, but if there was one thing I could change, it would be the verb-noun order. The Kakoune[1] editor behaves mostly like Vim, but where Vim has `dw` as "delete word", Kakoune has it backwards: `wd`.
It might sound minor, but by placing the range first, Kakoune can give a preview of what will be changed. The longer or more complicated the command, the more this feature shines.
Strictly better as far as I know. A shame my muscle memory, and all default installations, are still stuck with Vim.
