Even though the C language has been around for over 50 years, it continues to be incredibly popular. There are however missing features of a “modern” higher level programming languages such as C++, C#, Rust and more that haven’t been addressed by updated C versions. Zen C steps in to try and solve many of these missing features and it does it by transpiling down to C (C11) human readable code. This lets you write your code at a high level of abstraction, while maintaining the low level performance and determination of C code.
Highlight features that Zen C adds to the C programming language includes:
RAII (Resource Acquisition Is Initialization): Automatic management of resources via constructors and destructors, ensuring memory or handles are freed immediately when they go out of scope.
Generics: Native support for type-parameterized functions and structs, eliminating the need for void* or macro-based “generic” C.
defer Statement: Schedules code to execute at the end of the current scope, making cleanup logic much easier to track and preventing resource leaks.
Type Inference: Use of the var keyword to let the compiler infer types, significantly reducing boilerplate and making the code more readable.
Pattern Matching: Powerful match blocks that replace traditional switch statements and support destructuring of complex data.
autofree Keyword: A high-level implementation of RAII that specifically manages the lifecycle of local heap allocations for you automatically.
Uniform Function Call Syntax (UFCS): Allows calling functions with dot-notation (e.g., list.push(item)), providing an object-oriented feel without the overhead.
Tagged Unions: Enums that can carry associated data (Sum Types), enabling safe and expressive Option<T> or Result<T, E> patterns.
Traits: Defines shared interfaces and behaviors across types, providing a modern polymorphism system while maintaining C performance.
Inline C++ Code: The ability to drop into C++ blocks directly to leverage existing C++ libraries or features while staying primarily in Zen-C.
Inline Assembly (ASM): Full support for the asm keyword, allowing you to write architecture-specific instructions directly in your source for maximum optimization.
String Interpolation: First-class f-string support (e.g., f"Score: {score}") that transpiles into efficient string logic, replacing messy sprintf calls.
Built-in Collections: Native, high-performance support for growable vectors and hash maps directly within the core language experience.
Guard & Unless: Specialized control flow structures designed to clean up “early return” logic and keep the “happy path” of a function visible.
Async/Await: Syntactic sugar for asynchronous programming, removing the need to manually manage complex state machines.
Named Arguments: The ability to specify parameter names in function calls, creating more self-documenting and readable code.
UTF-8 Support: Native, first-class handling of modern character encoding for global software development.
