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
> concatenating them changes the label for [b] from "a" to "z\na", and perhaps more damningly, erases the whitespace before "z". But, since none of the alternative formats (except ndjson and I guess plain uninterpreted binary, ASCII, or Unicode) is closed under concatenation, maybe that's less important.
Yes, being closed under concatenation is a feature I was aiming for and it indeed does bring with it this issue.
Just something to have in mind when devising formats. A simple solution here is to disallow having anything other than whitespace in the suffix of a Jevko with > 0 children. Then, if a format converts these labels to keys in a map, trimming leading and trailing whitespace, there is no problem. This is how I did it here:
https://github.com/jevko/easyjevko.js
> I don't know if you saw the last time this topic came up I linked to https://ogdl.org/, which seems pretty close to a minimal rose-tree notation.
Yes, I've seen OGDL before. It's pretty nice. A similar one is https://treenotation.org/
I have experimented with indentation-based syntaxes myself, before settling on brackets.
I have found them to be problematic, at least because:
* For complex structures they become less compact.
* A grammar that correctly captures significant indentation can't really be written in pure BNF. The way OGDL does it is this:
[12] space(n) ::= char_space*n ; where n is the equivalent number of spaces (can be 0)

Syntax Design
This reminds me a bit of Breck Yunits' Tree Notation (https://treenotation.org/). Both seem to have a ~totalizing energy. Maybe some common cause. :)

ELI5
Hi, I'm a programmer and I've used quite a few different languages in my career. I've never studied compilers or language design, however it has always interested me from afar. Also I've always had a strong preference for simple syntax, what sane person wouldn't? Anyway I've scanned over the https://treenotation.org/ site. I get the general gist, that this provides a tool to easily create languages that use tree notation. Unfortunately I still don't really understand how to use it. If there was tutorial that held your hand that would be really useful. I suspect there a large number of people like myself that would benefit from this. Perhaps at some point I'll role up my sleeves and do it myself, but I'm sure someone else could do a better job.

Google Docs will move to canvas based rendering instead of DOM
> The way to fix this trend would be to reimagine the presentation layer of the browser as something other than a stack of hacks over hypertext, but so far nobody seems to have a good solution.
About a decade ago I had the start of a Eureka moment on how to do this (back then — https://medium.com/space-net/spacenet-51aca95d49a2, nowadays https://treenotation.org/). It seems to me we've missed a sort of fundamental universal notation of the universe, which you can think of as "two-dimensional binary". I predict we will soon see a Cambrian Explosion of new formats and notations that are simpler and more interoperable with each other, and some will have the opportunity to build new great languages for rendering stacks.

Zig, Parser Combinators – and Why They're
Awesome app. Do you plan on using it for anything in particular? Or are you just creating it as a passion project. It's totally cool.
Learning about https://treenotation.org/ (linking this for other people, not for you, Breck :P), and I like what I see. My first impression was "Lisp, but with python indenting"
> We no longer need to store our data in error prone CSV, XML, or JSON. Tree Notation gives us a simpler, more powerful encoding for data with lots of new advanced features
This is the one thing I didn't understand! Tree notation seems equivalent to these. Like at a certain level, it's all just data. Now, the major benefit is that you're supposed to think differently about what you're doing when using tree notation. Would love to hear your opinion about this conjecture.

Bun - The One Tool for All Your JavaScript/Typescript Project's Needs?
NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

Bun 1.1
ntdll.dll!RtlUserThreadStart()
There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.
