Core Features

Explicit Effects

Zero emphasizes explicit effects, allowing developers to clearly define the side effects of their code, which aids in reasoning about program behavior and improving predictability.

Source: per README
Predictable Memory

The language is designed to offer predictable memory management, which is crucial for small native tools where memory usage and performance are critical.

Source: per README
Structured Compiler Output

Zero's compiler produces structured output, which is beneficial for tooling and further processing of the compiled code.

Architecture

The architecture of Zero is modular, with separate components for the compiler, standard library, documentation, and examples. The code tree is organized into directories such as 'native/zero-c' for the compiler implementation, 'compiler-zero' for the Zero-authored compiler sources, and 'examples' for runnable Zero source examples. The project utilizes various scripts and workflows for building, testing, and documentation generation.
