Axe - A Systems Programming Language with Builtin Parallelism and No GC
I'm writing a compiler for a systems language focused on concurrency and parallelism. It’s a re-engineering of a prior work, with an explicit emphasis on memory management and type safety, plus first-class parallel primitives at the language level. The language is now capable of compiling a substantial portion of its own source code to tokens using a single-pass C back-end.

In plain words
Axe is a systems programming language compiler emphasizing concurrency and parallelism as first-class language features. It targets developers building high-performance software and includes explicit memory management, type safety, and no garbage collection. The self-hosted compiler uses a handwritten lexer and parser with an arena-based allocator for fast compilation, and can compile substantial portions of its own source code via a single-pass C backend.

In the maker’s words, at launch
I'm writing a compiler for a systems language focused on concurrency and parallelism. It’s a re-engineering of a prior work, with an explicit emphasis on memory management and type safety, plus first-class parallel primitives at the language level. The language is now capable of compiling a substantial portion of its own source code to tokens using a single-pass C back-end. The self-hosted compiler includes a handwritten lexer and a parser, with an arena-based allocator to support fast compilation and eliminate GC complexity. The primary goals for the project are: First-class parallel and concurrent constructs built directly into the language, strong static memory and type guarantees, and a toolchain suitable for building high-performance software Example: def main() { parallel local(mut arena: Arena) { arena = Arena.create(1024); val tid = Parallel.thread_id(); val result = worker(ref_of(arena), tid); println $"Thread {tid} computed {result}"; Arena.destroy(ref_of(arena)); } } You can find the repository here: https://github.com/axelang/axe
