What it does
Civet is a new programming language that compiles to TypeScript. It's 99% compatible with existing TypeScript but provides additional syntax to simplify common patterns. There's a lot of enhanced JSX features and many smaller quality of life improvements. Give Civet a try today!
Code More with Less in a TypeScript Superset
Civet is a programming language that compiles to TypeScript or JavaScript , so you can use existing tooling (including VSCode type checking, hints, completion, etc.) while enabling concise and powerful syntax. It starts with 99% JS/TS compatibility , making it easy to transition existing code bases. Then it adds many features and syntactic sugar, with some highlights below and more comprehensive examples in the reference . See also Civet's design philosophy and changelog .

I've spent the past few months building a language that is 99% compatible with CoffeeScript and 99% compatible with TypeScript. Essentially a reimagined CoffeeScript for 2022 that finished ES6s partially completed features, adds TypeScript support, and keeps the niceties of CoffeeScript. Example features: - Const assignment shorthand user := getUser() --- const user = getUser() - Parens optional and braceless nesting if x > 0 return --- if (x > 0) { return } - &fn shorthand nums.map &+1 --- nums.map($=>$+1) And a heck-ton more: https://github.com/DanielXMoore/Civet A big…

Deco.cx – realtime TypeScript web editor2024 · deco.cx · ▲98Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years. Deco.cx is the thing that we wish existed when we were managing hundreds of enterprise-grade React-based websites. The gist is: JSX, HTMX, TypeScript, Tailwind and Deno. All visually editable in a beautiful, collaborative,…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... Girl with a pearl earring: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... I integrated this new InstructPix2Pix model into imaginAIry (python library) so it's easy to use for python developers.

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
