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.

Creating a custom parser with PEGJS
The PEG.js project got taken over by a new maintainer who locked everyone else out, never shipped a release, and then ignored repeated requests to transfer the project back to the community. So the community forked it to a new project - Peggy, which is where ongoing development happens: https://github.com/peggyjs/peggy

How to make your own programming language in JavaScript
NOTE: The original PEG.js project is not maintained anymore, but there is a new fork, Peggy that is maintained and it's backward compatible with PEG.js so it will be easy to switch.

Show HN: DTL: a language and JavaScript lib to transform and manipulate data
Thanks. Yes, DTL's core textual syntax is described with PEG. I make use of the Peggy (https://peggyjs.org/) PEG processor to build up the AST that is used to actually process DTL.
There are C based PEG processors, which I've looked at once or twice also, but I haven't sat down to try to convert it. Mostly out of a desire to get the existing module to work well. A working module for one language is better than a partially working module for multiple. :P

Parsing in JavaScript: all the tools and libraries you can use
hmm this article is a bit outdated; peg.js (mentioned in the article) has been discountined for a few years now; recently the project was picked up by another team under the name peggy.js https://github.com/peggyjs/peggy

I pre-released my project "json-responder" written in Rust
JSON5 support

topoconfig: enhancing config declarations with graphs
Meanwhile, formats have been evolving (JSON5, YAML), config entry points are constantly changing. These fluctuations, fortunately, were covered by tools like the cosmiconfig.

That's a Lot of YAML
I think JSON5 is fairly close to this: https://json5.org
I reckon the only thing it's missing to be truly accessible to non-techies is that string values still need to be quoted, i.e. you can't have:
key: this is my value
(I'm definitely not saying it would be a good idea to allow quotes to be dropped, just that that's the only potential stumbling block I see for non-techies.)
-
XML is better than YAML
I believe that's JSON5.
https://github.com/json5/json5
It's my preferred configuration file format, it fixes all the problems I have with JSON (trailing commas, comments) without turning it into a mess full of gotchas like YAML.

JSON 5 support

TySON: a native go library that lets you use TypeScript as an embedded configuration language without depending on Node or V8
I would like to see mention of JSON5 which is 11 years its elder. For comments in JSON, JSON5 is a good starting point.
