Kittine updates https://kittine.com/updates What actually landed in Kittine, by date — condensed from the language repo's own CHANGELOG.md. en-us Thu, 23 Jul 2026 00:00:00 GMT Arrays of structs, closures, and pattern matching as an expression https://kittine.com/updates kittine-updates-2026-07-23 Thu, 23 Jul 2026 00:00:00 GMT A litter/breed name, optionally []-suffixed, is now a real prop/purr param or return type (DocEntry[] entries is a real Vec<DocEntry>); closure literals (|param, ..| expr) lower to real Rust closures for .filter()/.map(); pounce> now also works as an expression, unwrapping a Result-shaped value and returning it in one step. The Language reference page's search box is now real, built from exactly these three features. Phase 2 begins: maps, JSON, a reference operator, log levels https://kittine.com/updates kittine-updates-2026-07-22-phase2 Wed, 22 Jul 2026 00:00:00 GMT stash{ key: expr, .. } is a real String-keyed map; every litter/breed now derives serde::Serialize/Deserialize for JSON (or YAML/CSV) round-trips via serde_json::to_string(&value); a new &expr reference operator unblocks calling real Rust APIs that need one; warn<expr>/error<expr> join craft<expr> as real logging severity levels. Reading an event handler's actual value https://kittine.com/updates kittine-updates-2026-07-22 Wed, 22 Jul 2026 00:00:00 GMT The reserved event identifier, used anywhere inside an on<Event> handler, now reads what the browser event actually carries -- onInput={<{name}> >> event} mutates a signal to whatever was typed, not just a fixed literal. The handler's closure only binds ev when the expression actually reads event. A real package manager, and a live in-browser playground https://kittine.com/updates kittine-updates-2026-07-21 Tue, 21 Jul 2026 00:00:00 GMT kittine.toml/kittine.lock plus kittine-compiler add/install/publish, backed by a real hosted registry (kittine-registry) with sha256-verified downloads; the Playground -- kittine-compiler itself, compiled to WebAssembly, compiling .kitty to real Rust entirely client-side. Phase 1 closes: traits, structs, enums, pattern matching, generics https://kittine.com/updates kittine-updates-2026-07-19 Sun, 19 Jul 2026 00:00:00 GMT claw / bare .. for .. (a real trait system) plus bounded generics; litter (structs), breed (enums), pounce> (pattern matching), single-parameter generics; optional/inferred scalar type tags; the #n/#w/#f sigil redesign; a formal EBNF grammar; kebab-case JSX attributes. Real SSR, routing, and every operator this site needed https://kittine.com/updates kittine-updates-2026-07-18 Sat, 18 Jul 2026 00:00:00 GMT Server-side rendering via cargo-leptos + Axum; routing via leptos_router with dynamic segments and programmatic navigation; comparisons and logical &&/||; hold plain bindings; re-exports; private visibility; array-typed props/returns; reactive list rendering in views; component children. Initial release: the core language https://kittine.com/updates kittine-updates-2026-07-17 Fri, 17 Jul 2026 00:00:00 GMT func components, <{name}> >> value signals, if>/orif>/else> control flow, spin loops, the embedded JSX-like view syntax, craft<...> logging, and a VS Code extension with TextMate syntax highlighting.
