Anchor

A statically-typed programming language that transpiles to C99.

from core.math import abs

struct Pair
    a: int
    b: int

    func hash(): int
        return self.a ^ self.b
    end
end

interface Hashable
    func hash(): int
end

func get_hash(h: &Hashable): int
    return h.hash()
end

func main(): int
    var p = Pair(a = 3, b = 9)
    return get_hash(&p)
end

Features

• Clean syntax with end-delimited blocks
• Structs with methods, enums, and interfaces with implicit structural matching
• Generics with monomorphization
• References (&T) and nullable pointers (*T) with pointer arithmetic
• Scoped resource management via with / release()
• Module system with export / import
• Extern FFI to C functions
• Transpiles to readable C99, compiled with gcc/clang/cl

Prerequisites

A C compiler must be installed and available in your PATH: gcc, clang, or cl (MSVC).

Build

cmake -B build
cmake --build build

Usage

Run a single file:

bin/ancc.exe run file.anc

Build a multi-file package:

bin/ancc.exe build path/to/project

Testing

py tests/run_tests.py

Run a single test by name:

py tests/run_tests.py --filter enum_basic
