It would be great if you had a simple website that allowed you to enter SOML and see the JSON side-by-side (similar to typescript playground https://www.typescriptlang.org/play/).
I don't want to read Claude's interpretation of why your project matters. I want you to tell me directly.
1. The readme doesn't make it clear what its "float" type is. A double, a decimal, implementation defined. I'm generally not a fan of restricting numbers to what a double can represent, like toml does.
2. It doesn't have a good way to model key-value pair like types such as tagged unions, polymorphic types, or function invocations. Simply allowing a key-value pair as a value (right associative) where the key is a string matching the keys of an object would fix this. Alternatively a function call syntax would fix this, which would also enable tuples as a concept distinct from arrays.
I’ve been building Forma (https://forma-lang.com), a small typed Lisp aimed at that zone. Everything is (head args...), so a tagged value and a call are the same syntax, and you declare the vocabulary yourself:
(job nightly-export
:schedule "0 3 * * *"
:retry (backoff :max 5))
I think cue is better thought of as a language you use to generate JSON (or yaml, or, let's be honest, k8s flavored yaml) configs rather than a config language you use in your app.
I'm curious for example configs that are top-level lists?
