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.

Python toolkits
Sphinx along with MyST-parser to write documentation in markdown. I recently discovered portray which seems like a nice alternative as it supports markdown by default for both generic documentation and docstring in modules, class, methods and functions.

On Yak Shaving and, a New HTML Element for Markdown
https://github.com/executablebooks/myst-parser :
> MyST is a rich and extensible flavor of Markdown meant for technical documentation and publishing.
> MyST is a flavor of markdown that is designed for simplicity, flexibility, and extensibility. This repository serves as the reference implementation of MyST Markdown, as well as a collection of tools to support working with MyST in Python and Sphinx. It contains an extended CommonMark-compliant parser using markdown-it-py, as well as a Sphinx extension that allows you to write MyST Markdown in Sphinx.

> *Follows the CommonMark spec for baseline parsing;

A step towards educating with Spyder
This project is just the first step towards making Spyder an educational tool. In the future, we hope that we can develop the infrastructure necessary to support in-IDE tutorials, by improving the tools like Jupyter Book, sphinx-thebe, MyST-Parser which will provide better integration to write educational tutorials.

Show HN: I wrote a RDBMS (SQLite clone) from scratch in pure Python
Lark supports, and recommends, writing and storing the grammar in a .lark file. We have syntax highlighting support in all major IDEs, and even in github itself. For example, here is Lark's built-in grammar for Python: https://github.com/lark-parser/lark/blob/master/lark/grammar...
You can also test grammars "live" in our online IDE: https://www.lark-parser.org/ide/
The rationale is that it's more terse and has less visual clutter than a DSL over Python, which makes it easier to read and write.

Oops, I wrote yet another SQLAlchemy alternative (looking for contributors!)
First, let me introduce myself. My name is Erez. You may know some of the Python libraries I wrote in the past: Lark, Preql and Data-diff.

Hey guys, have any of you tried creating your own language using Python? I'm interested in giving it a shot and was wondering if anyone has any tips or resources to recommend. Thanks in advance!
It's not super maintained but you might enjoy building something with ppci, Pure Python Compiler Infrastructure. It has some front-ends and some back-ends. There's also PeachPy for an assembler. People like using Lark for parsing, I hear.

Is it possible to propagate higher level constructs (+, *) to the generated parse tree in an LR-style parser?
lark, a parsing library where I am somewhat involved has a really nice solution to this: Rules starting with _ are inlined in a post processing step.

can you create your own program language in python, if yes how?
Lark is a good library to assist with this.
- Lark a Python lexer/parser library

Create your own scripting language in Python with Sly
If I may ask, did you consider Lark, and if so, why wasn't it fit for your purposes?

Not Your Grandfather’s Perl
A grammar provides the high level constructs you need to define the "shape" of your data, and it largely takes care of the rest. Grammar libraries exist in other language (eg. lark or Parsimonius in Python) and they weren't created just to make XML parsing easier.

Earley Parsing Explained
I made a solid attempt at an Earley parser framework of my own, but apparently to get the most reliable performance from Earley parsing you need to implement Joop Leo's improvement for right-recursive grammars, which nobody has been able to adequately explain to me. I've read Kegler's open letter to Vaillant, I've tried to read other implementations, I've even tried to beat my head against the original academic paper, but I don't have the background knowledge to make sense of it all.
