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.

Ask HN: Which tools are worth the time?

My 2023 Terminal, Shell and Command-Line Toolbox
A lot of the tools in the post build on top of standard unix tools and are like for like (better) replacements. Many of them have been pulled from the Modern Unix repo on Github.

TIL you can do `cat -n file` to easily see line numbers when looking at a file
Plug to modern unix, a collection of utilities that modernize "standard" nix utilities (combination of faster, prettier, easier to use, as well as sensible defaults like highlighting and line numbers when not piped).

What are some things you can do in the terminal for entertainment?
I google something like "Modern Unix", open blogs, and try to find a "life-changing" tool that I haven't tried yet. Then I spend 1 day reading man how to apply this unreal tool to my current work environment setup. Ultimately, I'm sad because I wasted 1 day, but the process is fun enough to do it again tomorrow. This is like distro-hopping but tool-hopping. Now I have fzf, bat, helix, zoxide etc, but that's just the beginning of my tool-hopping :)

erdtree: A modern, multi-threaded, and ️🌈aesthetic️🌈 alternative to tree and du - v1.7.0 release ️
While this is not at all comprehensive of all the cool tools out there, there's this list which has a lot of modern alternatives to all of the modern Unix commands we know and love, most of which are written in Rust.

LeanCreator - a lean, cross-platform, single file IDE for C/C++
Yeah, fine, since Go and Rust it is common to have this "one file app" that you put in $PATH and call it a day. Now, how many of those are not a single CLI utility (e.g. a replacement for top/ls/du or other UNIX utility), and are full blown GUI app? Not so many. None that I can think of from the top of my head, actually.

Zed is now open source
The homepage has a benchmark that compares Zed's "insertion latency" to other editors, and this is the description:
> Open input.rs at the end of line 21 in rust-lang/regex. Type z 10 times, measure how long it takes for each z to display since hitting the z key.
Could someone clarify what that means? My interpretation of that was to go to https://github.com/rust-lang/regex/blob/master/regex-cli/arg... and start typing 'z' at the end of line 21, but that doesn't seem to make any sense. I guess that repo got refactored and those instructions are out of date?

CryptoFlow: Building a secure and scalable system with Axum and SvelteKit - Part 3
We also used the avenue to sluggify the question title. We used regex to fish out and replace all occurrences of punctuation and symbol characters with an empty string and using the itertools crate, we joined the words back together into a single string, where each word is separated by a hyphen ("-").

Command Line Rust is a great book
Command-Line Rust taught me how to use crates like clap, assert_cmd, and regex. I felt lost before because I didn't know about Rust's ecosystem--which is arguably as important as the language itself. Also, looking up and comparing libraries is a tiring task! blessed.rs is nice but Command-Line Rust really saved me from analysis paralysis.

Common Rust Lifetime Misconceptions
burntsushi actually regrets making regex replace return a Cow: https://github.com/rust-lang/regex/issues/676#issuecomment-6.... I’m glad it does, and wish it took an impl Into> there, for the reasons discussed in the issue, but burntsushi has a lot more experience of the practical outcomes of this. Just something more to think about.

Advent of Code 2023 is nigh
I'm not familiar with the AoC problem. You might be able to. But RegexSet doesn't give you match offsets.
You can drop down to regex-automata, which does let you do multi-regex search and it will tell you which patterns match[1]. The docs have an example of a simple lexer[2]. But... that will only give you non-overlapping matches.
You can drop down to an even lower level of abstraction and get multi-pattern overlapping matches[3], but it's awkward. The comment there explains that I had initially tried to provide a higher level API for it, but was unsure of what the semantics should be. Getting the starting position in particular is a bit of a wrinkle.

Regex Engine Internals as a Library
https://www.cs.princeton.edu/courses/archive/fall19/cos226/l... and https://kean.blog/post/lets-build-regex are excellent introductions to implementing a (very) simplified regex engine: construct a nondetermistic finite state automaton for the regex, then perform a graph search on the resulting digraph; if the vertex corresponding to your end state is reachable, you have a match.
I think this exercise is valuable for anyone writing regexes to not only understand that there's less magic than one might think, but also to visualize a bunch of balls bouncing along an NFA - that bug you inevitably hit in production due to catastrophic backtracking now takes on a physical meaning!
Separately re: the OP, https://github.com/rust-lang/regex/issues/822 (and specifically BurntSushi's comment at the very end of the issue) adds really useful context to the paragraph in the OP about niche APIs: https://blog.burntsushi.net/regex-internals/#problem-request... - searching with multiple regexes simultaneously against a text is both incredibly complex and incredibly useful, and I can't wait to see what the community comes up with for this pattern!
