A high-performance systems programming language focused on simplicity, Mutable Value Semantics, and Copy-on-Write memory management.

Status

Antimatter is currently in active development. The lexer and parser are complete, while the semantic checker, compiler pipeline, and code generation are still being built.

Latest Update: Engineering Log #2

The Core Concept

Antimatter is designed to remove the need for a garbage collector while keeping the language practical, predictable, and easy to use. It aims to combine performance, safety, and simplicity in a single system.

• Native Primitives: No heap overhead for Int, Float, Bool.
• CoW Memory: Automatic safety via reference counting and deep-copy-on-mutation.
• Zero-Cost Borrows: Immutable, stack-only pointers for function arguments.
• Cycle Handling: Cyclic references are handled using an @weak compiler directive to prevent memory leaks.

Error Handling Philosophy

Antimatter also aims to introduce a new and simpler way of managing errors. The goal is to make error handling more structured, more expressive, and less painful without adding unnecessary runtime cost.

Technical Architecture

• Runtime: Rust-based memory management layer.
• Backend: Emits QBE IR for efficient native code generation.
