   Jaws – a JavaScript to WASM ahead-of-time compiler▲290

   I've open sourced a JavaScript to WASM compiler. It's an experimental tool, but given the semantics I already implemented, I'm fairly certain I am able to eventually cover 100% of JavaScript spec. Any ideas, questions or critique welcomed! If you are interested in WASM, especially with new proposals like WASM GC or exception handling, it might be a good source of seeing these features in action - the project has a few thousand lines of hand written WAT so far.

   A stab at building my own string diffing library▲29

   Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

    A JavaScript UI library for imperative JSX▲41

    I've been building a web UI library for a side project of mine. I thought it might be useful to others, so I'm releasing it as open source. To put it simply, I realized that most of my pain points with React come from its declarative model ui=f(state). So I'm trying something that I'm calling "imperative JSX." Instead of treating JSX as the source of truth for your UI, it essentially becomes a query interface for DOM manipulation. I first had the idea for it a few months ago, and only began writing it in earnest last week, so it's extremely early and nowhere near production-ready. Still, I'd…

    es6_maps, new Elixir syntax feature via runtime compiler hacking▲71

    Hi HN! I thought you might enjoy this even if you don't know much about Elixir. `es6_maps` is a small library that introduces a "shorthand" map creation syntax, similar to shorthand object construction in JavaScript/TypeScript. For those unfamiliar with Elixir, the most interesting aspect might be how it achieves this. `es6_maps` takes advantage of BEAM (Erlang's VM) hot-reload capabilities to amend the Elixir compiler bytecode at runtime, adding functions that expand the shorthand syntax for further compilation. I think it's a nice showcase of the power you can wield (with care) when…

    Codegen – OSS Python Library for Advanced Code Manipulation▲14

    Hey HN! We've just open-sourced Codegen (https://github.com/codegen-sh/codegen-sdk), a Python library for manipulating Python + JS/React codebases. Codegen was engineered backwards from real-world, large-scale codebase analysis + refactors we performed on multi-million-line enterprise codebases. It provides a scriptable interface to a powerful, multi-lingual language server built on Tree-sitter. We realized that many code transformation tasks that impact large teams - refactors, enforcing patterns, analyzing control flow - are fundamentally programmatic operations.…
