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.

I'm wanting to write my first compiler, but getting a little bit mixed up in general.
Kind of an interpreter but it does compile to bytecode and is written in rust https://github.com/rust-hosted-langs/book I thought it was a great tutorial, both for learning rust, and about compilers

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.
