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.

Beating the fastest lexer generator in Rust
This is mighty impressive! I've been trying to get some motivation for the mythical rewrite of the proc macro in Logos, and this might just do it for me :D. I'll have a proper look later today and see if any of your findings have something that can be generalized. Also really surprised to see aarch64 doing better than x86_64 since the latter is what I've been optimizing for!

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...).

loxcraft: a compiler, language server, and online playground for the Lox programming language
rust-langdev has a lot of libraries for building compilers in Rust. Perhaps you could use these to make your implementation easier, and revisit it later if you want to build things from scratch. I'd suggest logos for lexing, LALRPOP / chumsky for parsing, and rust-gc for garbage collection.

Logos 0.13 released
Thanks! For compile times you might find the CLI version that Andrew Hickman contributed useful, it's undocumented still mostly I fear but shouldn't be hard to use, see original PR: https://github.com/maciejhirsz/logos/pull/248

Should I revisit my choice to use nom?
For my lexer generation purposes, I tend to use https://github.com/maciejhirsz/logos, as it not only generates an easy to use lazy lexer, but the result is also exceptionally fast!

Position in rowan
Hi, I'm using rowan to create a parser and want to print more useful error messages with position in the text/file. I'm using logos (https://crates.io/crates/logos) to generate the lexer. Is there a way to get the starting and ending positions of a SyntaxToken? If not I thought of adding my own wrapper struct around the SyntaxTokens.

Hey Rustaceans! Got a question? Ask here (6/2023)!
Is there a way for a lexer created with the logos crate (https://crates.io/crates/logos) to get the starting and ending positions for the tokens?
-
Best resources for a rust interpreter?
I wouldn't recommend Logos at this point. This recent bug is quite nasty and seems easy to hit, and the maintainer is unresponsive. Last commit was half a year ago. At this point I consider Logos abandonware, though it would be great if its development continued, or if it were forked.

What's the coolest Rust project you've seen that made you go, 'Wow, I didn't know Rust could do that!'?
Hope you are aware that structopt is in maintenance mode and is merged into clap as of v3.

Task manager for Linux using rust
As I understood you need to implement a command line argument parser for that you can use clap https://github.com/clap-rs/clap or structopt https://github.com/TeXitoi/structopt.

clap 3.1: A step towards 4.0
Something I've been giving thought to is how to help structopt users discover that clap3 is their upgrade path. We've put notices in the structopt repo but cargo upgrade and docs.rs won't say anything. See https://github.com/TeXitoi/structopt/issues/525 for more ideas we're considering.

ANN: clap 3.0.0-rc.0!
For myself, I have found serde.rs really useful for undertanding their derives while I've always been frustrated with finding anything in structopt's documentation, so I modeled it more off of serde. This ended up both being in structure and not being in docs.rs. I think it really was the structure that was the frustration point for me but there was interest elsewhere in moving stuff out of docs.rs.

fncmd: Command line interface as a function.
I think it would be nice to have a comparison to clap-derive and/or structopt in the README, as that is what I expect most users would compare this to. The subcommand handling looks especially cumbersome compared to deriving on structs and enums.

Linkerd 2.11 now includes a Kubernetes controller written in Rust
However, the one place I'm a little curious to rewrite things is the CLI... every time we have to deal with cobra I long for Rust's structopt.

SwayWS - a sway workspace tool which allows easy moving of workspaces to and from outputs
It is written in Rust using the structopt and swayipc crates. It is published on crates.io. The repository is hosted on GitLab. The repository is mirrored on GitHub.
