What Hacker News says
12 sourcesThanks for the report! This was tricky to track down, but I've got a fix: https://github.com/DanielXMoore/Civet/pull/1501
In Civet: A Superset of TypeScriptThe pattern matching (TC39 stage 1) and pipeline operators (TC39 stage 2) look great, and I'd love to have those in TypeScript. It will probably take a loooong while for those features to be available in JavaScript, but I feel like I can live without those for now :-).
Fwiw it seems a lot of people really like the concept of "significant indentation". I'm thinking Python, YAML, Godot's GDScript. Not a lof of languages implement it but those that do seem to get a lot of users.
Interestingly, it seems like Erik Demain [1] is one of the contributors [2] of this project.

In Civet: A Superset of TypeScriptCivet just added a bun loader https://github.com/DanielXMoore/Civet/blob/main/source/bun-c...
I'm curious to hear your thoughts about Bun/Civet integration to explore improvements to the language frontend as well as the language backend?
In Bun v0.5Have you seen "The modern way to write TypeScript"?

*runs for cover*
In Don't use Tailwind for a design system (2021)I'm working on a new "transpiles to TypeScript" language called Civet. It's essentially a new CoffeeScript for TypeScript.

In Ask HN: What are you working on this year?That's how I do it in Civet (the CoffeeScript of TypeScript). It's a very small amount of complexity to add to the parser for a ton of convenience when using the language. https://github.com/DanielXMoore/Civet
In Delimiter-first codeShow HN: Civet the CoffeeScript of TypeScript v0.4.20
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 milestone today: v0.4.20, parser hit 5kloc, and >666 tests.
Please share your thoughts, feelings, hopes, and dreams. Thank you for coming to my Ted Talk.
