C3 Programming Language

C3 is an evolution of C and a minimalist systems programming language.

Ergonomics and Safety

• Optionals to safely and quickly handle errors and null values.
• Defer to clean up resources.
• Slices and foreach for safe iteration.
• Contracts in comments to add constraints to your code.
• Automatically free memory after use in @pool() context.

Performance by Default

• Write SIMD vectors to program the hardware directly.
• Access to different memory allocators to fine-tune performance.
• Zero-overhead errors.
• Fast compilation times.
• Industrial-strength optimizations backed by LLVM.
• Easy-to-use inline assembly.

Batteries-Included Standard Library

• Dynamic containers and strings.
• Cross-platform abstractions for ease of use.
• Access to the native platform when you need it.

Leverage Existing C or C++ Libraries

• Full C ABI compatibility.
• C3 can link C code; C can link C3 code.

Simple Modules

• Modules namespace code.
• Modules make encapsulation simple with explicit control.
• Interfaces define shared behavior to write robust libraries.
• Generic modules make extending code easier.
• Simple struct composition and reuse with struct subtyping.

Simple Macros

• Macros can be similar to normal functions.
• Or write code that understands the types in your code.
