   I made Confetti: a configuration language file format▲67

   Hello everyone, I created Confetti: a simple, typeless, and localization-friendly configuration language designed for human-editable configuration files. In my opinion, JSON works well for data interchange, but it's overused for configuration, it's not localization-friendly, and it's too syntactically noisy. INI is simple but lacks hierarchical structures and doesn't have a formal specification. Confetti is intended to bridge the gap. I aim to keep Confetti simple and minimalistic, while encouraging others to extend it. Think of it like Markdown for configuration files: there's a core…

   ECSS – Simple rules for efficient CSS▲43

   A list of CSS authoring rules with examples and a Stylelint config accessible from the top of the page. I've come to these through 20 years of experience and a willingness to make vanilla CSS a better alternative to frameworks. I encourage you all to comment on the rules themselves and the Stylelint Config for ECSS. Here's the link for faster access (I still suggest at least zipping through the rules beforehand). https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;@efficientcss&#x2F;stylelint-config...

    Flintable – Fixable ESLint rules Playground▲14

    Hi community! I am glad to introduce to you my latest project! What? Flintable is a playground for experimenting lint rules, focusing on fixable layout and suggestions rules. I initially focused on ESLint, the most popular JavaScript linter. Flintable allows adding your code and regularly testing it with individual rules or custom configurations, composing your own configuration file. How? I developed Flintable using the PHP Laravel framework for the server side and the Vue framework linking them with Inertia JS, accompanied by Tailwind CSS for the client side. Laravel Horizon manages the…

    Crust – A CLI framework for TypeScript and Bun▲95

    We've been building Crust (https:&#x2F;&#x2F;crustjs.com&#x2F;), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

    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&#x2F;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…
