Products that do what Compose-regexp.js Build readable and maintainable RegExps. ReDOS begone does
This is an old lib I just rejuvenated, adding support for Unicode RegExps, properly handling back-references, and taking advantage of these to create helpers that turn things that are usually too impractical to use into usable techniques. It lets you write anything you'd write with normal RegExps, but with a more readable syntax, and it lets you compose sub-expressions into larger patterns. It also provides helpers like: - `atomic()` that prevents the engine from backtracking into what you passed as argument. No more ReDOS. - `bound()` works like `\b` but for arbitrary character sets. E.g.…

eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone! Last but…

Hey folks, I just wanted to share a quick script I threw together called notational ls. One of the big problems of any code base (or any filesystem) is that it's hard to tell what's what - folder and file names often trade brevity for clarity. So I thought about a version of `ls` that works like this: > nls web: Where python web server files are stored ad_hoc: One time scripts ios: Our IOS code images Adding descriptions is really easy too: > nls images Images SHARED between both ios and web web: Where python web server files are stored ad_hoc: One time scripts ios: Our IOS code…

You can enter strings to match/not match and the generator will spit out an according regex. It's not 100% accurate, but I feel like this could still be useful in at least getting a starting point when initially trying to make a regex?

hi hn, today I'm open sourcing a new SQL-like query language that's built for the web. it has dedicated syntax for request, parsers, selectors, and javascript snippets... it was built on nodejs with the incredible moo lexer and nearley parser. if you're a fan of regular expressions, do I have some code to show you! the website is mostly just a few examples and a playground where you can write & run (& share!) your own queries. there's also an introductory blog post where i try but ultimately fail to justify why this should be its own language and not a library/framework. enjoy!

Hi HN. I've been working on this since 2018. Revise.js is a set of building blocks for contenteditable: a web component that gives you a textarea-like .value for any contenteditable element, an Edit data structure with compose/transform/invert for OT inspired by the Xi editor, and a Crank.js integration for declarative editable components. At 32.8 KB gzipped (including the rendering framework), it's 2–4x smaller than ProseMirror, Slate, or CodeMirror. The trade-off is that those ship complete editors; Revise is foundations you build on. All the demos on the homepage are live and…
