Highlights:

• Core Engine:
  • Logos zero-copy DFA lexer with full support for PHP identifiers, superglobals, and keywords.
  • Custom Pratt expression parser supporting full operator precedence and symbol rewriting.
  • Development Mode (rhp run dev) featuring a direct tree-walking AST interpreter for sub-millisecond cold starts and hot reloading.
  • Production Mode (rhp run build) lowering AST into linear IR opcodes with Cranelift JIT execution on a multi-worker Tokio pool.
• Native Facade Standard Library:
  • Arr: Explicit subtyped collections (list, dict, set, hashMap) backed by Rust Vec, IndexMap, and HashSet.
  • Str: Binary-safe raw byte storage with 23-byte small string optimization (SSO) and UTF-8 safety checks.
  • Future: Tokio fiber concurrency with Future::run, Future::wait, Future::any, and post-response Future::defer.
  • Memory: 100% GC-free deterministic destruction, bump request arena, and cycle prevention.
  • Sys: System intrinsics (env, print, dd, version).
• Tooling:
  • Integrated rhp run lint combining AST auto-formatting (4-space indent), casing normalization, automated variable type inference, and JSON diagnostic reporting.
