enzotar	ca45c688df	feat: for-in list rendering + component system ... Phase 6 features: - ForIn reactive list rendering: for item in items -> body - Optional index binding: for item, idx in items -> body - Component declarations: component Name(props) = body - Component instantiation: ComponentUse { name, props } Added across 5 crates: - ds-parser: For/In/Component tokens, ForIn/ComponentDecl AST nodes - ds-codegen: reactive list effect, component function emission - ds-types: ForIn/ComponentUse type inference - local_vars tracking for non-reactive for-in loop vars Includes examples/list.ds showcasing for-in + when + signals.	2026-02-25 01:33:28 -08:00
enzotar	462663830e	feat: Phase 3+4 — Cassowary constraint solver + type system ... Phase 3 — Constraint Layout: - ds-layout crate: Gaussian elimination constraint solver - eq, gte, lte, sum_eq, ratio constraints with strength priority - get_rect() for resolving absolute (x,y,w,h) layouts - 7 tests: simple eq, two-var eq, sums, rects, gte, ratio, 3-panel Phase 4 — Type System: - ds-types crate: Signal<T>, Derived<T>, Stream<T>, Spring<T>, View - Effect types: Http, Storage, Time, Dom, Custom(name) - Hindley-Milner type checker with signal-awareness - Elm-inspired error messages (TYPE MISMATCH, UNHANDLED EFFECT, etc.) - 11 tests: type display, reactive checks, mismatch errors, etc. Total: 34 tests passing across 6 crates	2026-02-25 00:22:35 -08:00
