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.

Jevko: a minimal general-purpose syntax
Thank you for your feedback. Can you clarify?
What is the "first page" that you are referring to?
Can you paste a link to it along with the broken examples link?
This Hacker News submission features the blog post under this URL:
https://djedr.github.io/posts/jevko-2022-02-22.html
Clearly, you are not talking about this page, as that contains multiple links rather than a singular link.
Perhaps you are talking about the specification which is here:
https://github.com/jevko/specifications/blob/master/spec-sta...
(linked from the blog post)
and here:
https://jevko.org/spec.html
(linked from jevko.org)
All three link to Jevko examples here:
https://github.com/jevko/examples
but all these examples links seem to be correct on my end.
I agree about the importance of examples, and I try to lead with them on jevko.org and jevko.github.io (which are the front pages of Jevko -- possibly I should merge them into one).
However a formal specification is not necessarily the place to put the leading examples.
This is also where the Subjevko rule is defined. It isn't quite introduced as "known knowledge" -- the purpose of a specification is to define the unknown, more or less from the ground up. This is also why specifications tend to get a little abstract. Jevko's spec is no exception. This should be in line with expectations of authors of tools such as parsers, validators, generators, or other kinds of processors, for which the spec is the authoritative reference.
It is not necessarily the best first place to look for explanation, if you are approaching from a more casual side.
I agree that from that side a clear picture of what Jevko is and how it can be used is still lacking. I certainly should add more examples and explain the concepts with analogies.
So I appreciate the essence of your advice and hope I'll manage to improve on that.

Jevko: a minimal general-purpose syntax
The grammar of S-exps on the other hand, I won't quote here, but I assure you it's much more complicated. How much depends on your flavor (Jevko is also simpler in this regard: there is only one flavor, clearly specified).
There is no (intended) ambiguity around whitespace in Jevko: whitespace does not occur explicitly in the grammar. Whitespace characters are just characters. This is the defining feature of the syntax.
For this reason Jevko is more low-level: if you want to treat whitespace in some special way, you have to do that yourself. Although for most use-cases this is very similar and simple, e.g. https://news.ycombinator.com/item?id=33334314
But the point is that you can also leave it as-is, e.g.: https://github.com/jevko/queryjevko.js
or do something else -- it's up to your format.

Syntax Design
Thank you. :)
> I wonder if I should use it for something...
I'd be honored!
A couple of ideas:
How about a simple configuration format? https://gist.github.com/djedr/681e0199859874b3324eaa84192c42... (I should make a library out of this)
Or you can put it in your query strings to make them more humane: https://github.com/jevko/queryjevko.js
Or make up a markup DSL: https://github.com/jevko/markup-experiments#asttohtmltable
Or serialize game objects in your indie game. Or make it the interface of your experimental app. Or use it to shave off a few unnecessary characters off your data: https://jevko.github.io/compactness.html
No parser in your favorite language? A basic one should be only a couple dozen lines!
What are some alternatives?
binary-experiments - Experiments with various binary formats based on Jevko.
tree - A Data Modeling Programming Language
easyjevko.lua - An Easy Jevko library for Lua.
algebralang - at this time this is some example code of a language I want to build
community - Features Jevko-related things created by various authors
tutorials - Tutorials related to Jevko
yapl - YAml Programming Language
FileToCArray - Coverts any file to a C style array. (It can also do image color format and size coversion)
