KSON, a love-letter to the humans maintaining computer configuration

Hi friends, I'm really excited to introduce KSON, which just entered public beta! Anywhere a human is reading or editing YAML/JSON/TOML, KSON may be used as a more effective interface on that data. If you are such a human, we invite you to participate in this beta. tl;dr Check out the website [1], play with the online playground [2], install the library for your programming language [3], edit in your favorite editor [4], discuss and give feedback [5], contribute to the project [6]. (A personal note about this project: I love software. Machines made of words! Such a wonder. KSON itself, as a collection of words that both make a machine and explain that machine, is an expression of a lot ideas I feel really passionately about around software and our relationship to it. I've put a lot of love into trying to make that expression eloquent and reliable. I hope some of that comes through clearly, and I look forward to discussing this more over time with anyone who's interested) One of the key things KSON wants to say is: let's keep everything that's great about YAML and JSON as "Configuration User Interfaces", and let's make those interfaces more toolable, robust, and fun. Here's some of the ways we do that: - KSON is a verified superset of JSON, has native JSON Schema support, transpiles cleanly to YAML (with comments preserved!), and is likely available wherever you want it—current supported platforms: JS/TS, Python, Rust, JVM, and Kotlin Multiplatform. - KSON is also widely available in developer tools, with support for VS Code, Jetbrains IDEs, and anywhere you can plug in an LSP. - KSON is fully open source, licensed under Apache-2.0, and you are invited to meet its words and tinker with how they make its machine. A lot of care, craft, attention and joy went into making the KSON project understandable and approachable for developers. We hope to see you around. PS.
