NAAb

NAAb is a polyglot programming language that lets you write Python, JavaScript, Rust, C++, Go, Nim, Zig, Julia, Ruby, PHP, C#, and Shell in a single file. Use the best language for each task — variables flow across language boundaries automatically with zero boilerplate.

Built-in LLM governance engine with 50+ checks catches hallucinated APIs, oversimplified stubs, incomplete logic, and security vulnerabilities in AI-generated code. Three enforcement tiers (hard/soft/advisory) configurable via govern.json.

Key features:

• 12 embedded languages with automatic variable binding
• Empirical benchmarking: naab-lang calibrate measures real performance per language
• naab-lang race compares your polyglot blocks against faster alternatives
• Parallel polyglot execution with dependency analysis
• Lambda closures, pipeline operator, pattern matching
• 12 stdlib modules (array, string, math, json, http, file, io, time, env, csv, regex, crypto)
• SARIF and JUnit export for CI/CD integration

Built with 15,000+ lines of modern C++17. 195 tests passing. MIT licensed.
