Merged
Conversation
Ephapax is a linear type system for safe memory management targeting WebAssembly. This commit includes: Core Implementation: - ephapax-syntax: AST definitions with linear type annotations - ephapax-typing: Linear type checker with region support - ephapax-wasm: WASM code generator with bump allocation - ephapax-runtime: no_std WASM runtime with region management Formal Semantics (Coq): - Syntax.v: Core type and expression definitions - Typing.v: Linear typing rules with context tracking - Semantics.v: Operational semantics and safety theorems Documentation: - Language specification (spec/SPEC.md) - Comprehensive wiki documentation - ROADMAP.md with detailed development plan - CONTRIBUTING.adoc guide Infrastructure: - Cargo workspace with 4 crates - CI/CD workflow for Rust and Coq - EUPL-1.2 license Key features: - Linear types prevent use-after-free and memory leaks - Region-based memory management for bulk deallocation - Second-class borrows for temporary access - Formal proofs in Coq for type safety

Documents implementation status of 5 optional enhancements: 1. ✅ Debugger Support (Phase 1 complete: source maps + mode metadata) - Phases 2-4 planned (DWARF, DAP, VS Code integration) 2. ⏳ Package Manager (not started) - Cargo-style dependency management - Module import syntax - Local registry 3. ⏳ Performance Benchmarks (not started) - Ephapax vs Rust vs AssemblyScript - Compilation speed, binary size, runtime perf - CI integration 4. ⏳ VS Code Extension (not started) - Syntax highlighting - LSP integration (reuse existing ephapax-lsp) - Mode switcher UI 5. ⏳ Closure Environment Optimization (not started) - Escape analysis + free variable analysis - Minimal capture sets - 10-30% binary size reduction expected Overall completion: 20% (1/5 done) Recommended implementation order: #2 → #3 → #4 → #5 → #1 (complete) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
