Caution
Listen, this repo is just for fun. I had it private, but I care more about being able to run GitHub Actions to make sure that things are good, so I'm open sourcing this repo. Not everything in here is good, or accurate, or anything: I'm just messing around. Feel free to take a look but don't look too much into this just yet. Someday I'll actually talk about this.
A programming language that starts as a minimal subset of Rust, designed to explore cutting-edge compiler implementation techniques.
Rue is an experimental programming language with Rust-like syntax that compiles to native code. It focuses on modern compiler architecture including incremental compilation using Salsa, IDE-first design with concrete syntax trees, and direct ELF executable generation without external tooling.
The compiler supports both Cargo and Buck2 build systems.
The compiler is fully functional with a complete implementation pipeline from lexing through native code generation. It includes an LSP server for IDE integration and VS Code extension.
Platform Support: Linux x86-64 only
Current language support:
- Variables and assignment (let statements)
- Arithmetic operations (+, -, *, /, %)
- Control flow (if/else, while loops)
- Functions with optional parameters
- All values are 64-bit signed integers
The language server provides syntax highlighting and error detection:
See crates/rue-lsp/README.md for editor integration details.
See CONTRIBUTING.md for development guidance and docs/spec.md for the complete language specification.
