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.

The Super Tiny Compiler
> Some compilers tokenize while parsing, but for a different reason: it's faster and uses less memory to generate the AST
And some don't even generate an AST. :) Just read in and emit or interpret.

Let's write a compiler, part 3: A parser
I don’t think there will be an AST. https://briancallahan.net/blog/20210814.html: “We will be writing a single-pass compiler for a simple language and immediately output our final output code as soon as our compiler has enough information to do so”
That “as soon as” implies code will be generated before the entire program has been parsed.
Also, for me single-pass implies “no AST”, as you would need at least one pass to construct one, and iterating over an AST counts as another pass for me.
