Zixir v4.0.0 — Compiler, type system, and MLIR improvements

This release adds major improvements to the Zig backend, MLIR optimizations, type system, and parser: structs, maps, list comprehensions, try/catch, async/await, range expressions, comptime, defer, and self-healing AI pipelines. Plus automatic drift detection, A/B winner promotion, and data cleaning/validation.

1. Zig Backend (100%) ✅

  • Automatic drift detection and alerting ✅
  • Automatic winner promotion in A/B tests ✅
  • Automatic data cleaning and validation ✅
  • Self-healing AI pipelines ✅
  • Struct/type definition generation
  • Map literal generation
  • Struct initialization and field access
  • Better pattern matching (switch) codegen
  • List comprehension generation
  • Try/catch/finally expressions
  • Defer statements
  • Comptime blocks
  • Async/await expressions
  • Range expressions
  • Strength reduction optimization

2. MLIR (100%) ✅

  • Full dead code elimination with variable usage tracking
  • Constant propagation with type checking
  • Loop invariant code motion (LICM)
  • Strength reduction for common patterns
  • Better struct/map type representations

3. Type System (100%) ✅

  • Lambda type inference
  • Struct type inference
  • Struct field access type inference
  • Map types with key/value unification
  • Map access type inference
  • List comprehension type inference
  • Range expression types
  • Try/catch type inference
  • Future/async type inference

4. Parser (100%) ✅

  • List comprehension parsing ([expr for var in iterable if condition])
  • Map literal parsing ({key => value, ...})
  • Struct definition parsing (struct { field: Type })
  • Try/catch parsing
  • Async/await parsing
  • Range expression parsing (start..end)
  • Defer statement parsing
  • Comptime block parsing

Requirements

  • Elixir 1.14+ / OTP 25+
  • Zig 0.15+ (build-time; run mix zig.get after mix deps.get)
  • Python 3.8+ (optional) for ML/specialist calls

Quick start

git clone https://github.com/Zixir-lang/Zixir.git
cd Zixir
git checkout v4.0.0
mix deps.get
mix zig.get
mix compile
mix test
