Top 23 RegExp Open-Source Projects

RegExr
RegExr is a HTML/JS based tool for creating, testing, and learning about Regular Expressions.
When thinking about how I might compare an arrangement to the contiguous group of damaged springs, I used regexr.com to experiment with very specific regexs that used the numbers.

regex
An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.
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 I guess that repo got refactored and those instructions are out of date?

> I wonder if this could be used to make C# webassembly more viable.
You might enjoy reading this GitHub thread [0] where the community contributed a WASM library wrapping the C# regex code so that regex101.com could have a "C# mode". Lots of nerd sniping about reducing the payload size.
(There's also another thread [1] discussing the minification of a rust version of that same regex101 wasm library to provide a "rust mode" using @burntsushi's regex crate.)

As a ruby developer, I was happy to find that VS Code / TextMate grammar files use the same regular expression engine called Oniguruma as ruby itself. Thus, I could be sure that when trying my regular expressions in my favorite online regex tool, rubular.com, there would be no inconsistencies due to the engine inner workings.

Hang on.. doesn’t nvim-regexplainer already exist? And what are the key differences?

Before we start comparing the aforementioned solutions, it is worth to show how bad things are with the standard regex library in Go. I found the project where the author compares the performance of standard regex engines of various languages. The point of this benchmark is to repeatedly run 3 regular expressions over a predefined text. Go came in 3rd place in this benchmark! From the end....
