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
Here is a toy language that uses Jevko as syntax that I've been hacking on a bit recently: https://github.com/jevko/jevkalk
> is doing? It sure looks to me like it's asking whether a symbol (i.e. indivisible atom) ends with an equal sign, which is semantic gibberish.
There are no symbols or indivisible atoms here.
What's happening here is parsing. `jevkoToHtml` is a kind of parser-transpiler which operates on a syntax tree, rather than a sequence of characters or tokens.
The syntax tree is the output of an earlier stage of parsing, done by the Jevko parser.
So you can think of this as multi-pass parsing, by analogy with multi-pass compilation.
At the same time as this second pass of parsing is happening, translation to HTML is happening as well.
Hope this clarifies things!

November 2022 monthly "What are you working on?" thread
Been working on specifying the Utena machine. My initial plan was to add registers and instructions to the SECD machine as I usually do, to fit everything we need to keep track of. Notably, the Self machine keeps track of both "explicit" and "implicit" self; the former used for sends which explicitly write out the receiver e.g. self blah, and the latter used for sends with no explicit receiver e.g. blah.
What are some alternatives?
