CYMPLE
Procedural Programming with Unicode Symbols
Version 1.5 • 2025-12-15What is Cymple?
Cymple is a research programming language exploring novel approaches to procedural programming:
⚙️ Interpret or Compile
Cymple can be interpreted (like JavaScript) or compiled
🎓 Turing Complete
Cymple is Turing complete and can do everything needed
🔣 Unicode Symbols
Keywords replaced with expressive Unicode symbols for visual clarity
🚀 No Garbage Collection
RAII-based deterministic cleanup - perfect for real-time systems
🔐 Share-Nothing
Data races prevented by design through isolated task heaps
⚡ Quantum Operations
Parallel evaluation with timeouts, progress control, and early cancellation
🛡️ Memory Safe
Validated handles with generation counters prevent use-after-free
📋 Formally Specified
Complete formal specification with RFC 2119 conformance keywords
Quick Example
💬 "Hello, World!"
🆕 What's New in 1.5
- 🔥 Pointers Removed: Memory access only through validated handles - no pointer arithmetic
- ✅ Generational Validation: Handles carry generation counters to detect use-after-free
- 🧵 Structured Concurrency: Tasks automatically joined/cancelled at scope boundaries
- 🚦 Runtime Task Cap: Default 1000 concurrent tasks - prevents spawn storms
- 📋 Formal Specification: RFC 2119 keywords, statement index, error code ranges
- ✂️ Minimalism: No break/continue - functions and return are primary control flow
🎯 Design Principles
- 🛡️ Safety First: Memory safety and concurrency safety through validated handles
- 🎯 Determinism: Predictable behavior with lowest-index race tie-breaker
- 📢 Explicitness: No hidden allocations or background operations
- ⚡ Fail-Fast: Invalid operations cause immediate errors with clear messages
- ✂️ Minimalism: Small, focused feature set - functions are primary abstraction

🎯 Key Features
- Memory Safe: Generational handles prevent use-after-free
- Bounds Checked: All memory access validated at runtime
- Structured Concurrency: Tasks automatically cleaned up at scope exit
- Quantum Operations: Race (🌀⚡) and collect (🌀📦) with timeout units & early cancel
- Pattern Matching: Full destructuring with guards and ranges
- Borrowing: Temporary access without ownership transfer
- FFI: Direct C library integration
- Dual-Mode: Interpreted or compiled
- Tiny Binaries: Usually only a few KB (10× smaller than Go)
- Formally Specified: RFC 2119 conformance with complete semantics

⚠️ Note: The following examples are theoretical. Quantum operations (Race and Collect) are not implemented in the interpreter as of Cymple 1.4 or 1.5. They demonstrate syntax only.
