drip_core 0.1.0-alpha

High-performance, zero-dependency reactive engine for the DRIP framework. Synchronous-only tracking with microtask coalescing.

0.1.0-alpha - 2024-05-13

Initial Release of the DRIP Reactive Engine.

Added

• DripState<T> — atomic reactive value with version clock and equality check
• DripComputed<T> — lazy, cached derived value with automatic dependency tracking
• DripEffect — side-effect runner with automatic re-execution on dependency change
• DripScope — lifetime owner with LIFO disposal guarantee
• DripBatch — microtask-based coalescing scheduler (O(1) propagation passes)
• TrackingContext — stack-based, synchronous-only dependency registration
• Equality<T> interface with DefaultEquality and IdentityEquality implementations
• DripCircularDependencyError — thrown on circular computed dependency
• DripDisposedScopeError — thrown on access to disposed scope
• Top-level dripState<T>() factory function

Architecture

• Zero Flutter dependency — usable in Dart CLI and server applications
• Zero Zone-based tracking — async gaps never register spurious dependencies
• Pure Dart SDK >=3.3.0 — no third-party runtime dependencies

Testing

• 30+ unit tests covering all invariants
• CI-gated benchmark tests: write throughput, propagation efficiency, batching
