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.

Input lag in legion implementation vs specs
I've gotten to the part where I'm at a crossroads. I have two projects, one implemented in specs (following the website RLTK tutorial), and one implemented in Legion (from the same author's book).

Hey Rustaceans! Got an easy question? Ask here (5/2021)!
The currently broken (although the latest commit should work) version is on my github, and the re-work is over here! (as well as a graveyard of unfinished little projects)

Letlang — Roadblocks and how to overcome them - My programming language targeting Rust
Rust is a very nice langage for implementing compilers, and has a nice ecosystem for it (logos, rust-peg, lalrpop, astmaker -- this one is mine --, etc...).

Is there a parsing library (lexer?) which can handle generic tokens?
My peg crate is a parser generator that supports arbitrary token types as input. See https://github.com/kevinmehall/rust-peg/blob/master/tests/run-pass/tokens.rs for an example.

The one rust parser-generator I used is PEG

Hey Rustaceans! Got a question? Ask here! (29/2022)!
The two parser generators that I am aware of are lalrpop and PEG. There both great, and have seen some use by languages that have been written in Rust.

Using Nom - a parser combinator library
I wanted to create a parser for Apertium Stream. In 2014, I used Whittle in Ruby. If this year were 2001, I would use Lex/Yacc. Anyway, this year is 2021. I wanted to create this parser in Rust. I tried to find what is similar to Lex/Yacc. I found Rust-Peg. I found a link to Nom from Rust-Peg's document. My first impression was Nom example is easy to read. At least, its document claimed Nom is fast.

The peg crate has a resolved issue about this.

Rust is the second most used language for Advent of Code, after Python
I don't really know that much about parsing and grammars, other than what I've learned about regular languages and expressions and context-free languages in a standard Theory of Comp course from my university. I basically just learned peg by reading the Wikipedia article on PEGs, reading the crate documentation to understand the syntax, and then looking at some of the peg examples on their GitHub to understand how it works in practice.
