Blog Community Docs Research Contribute

Infrastructure Overview

  • hylo: The main compiler, written in Swift.
  • swifty-llvm: Swift wrapper around LLVM’s C API. We use this for code generation.
  • durian: A parser combinator library written in Swift, used by Hylo’s frontend.
  • hylo-dev-toolchain: It’s CI actions pre-build and publish Docker images with the development toolchain needed to build Hylo’s compiler.
  • llvm-build: Pre-built LLVM binaries with assertions enabled.
  • hylo-new: A rewrite of Hylo’s frontend with more principled architecture, implicit resolution, and significantly better performance (over 10x speedup). We are working towards merging this with the current compiler.
  • vscode-hylo: VSCode extension with syntax highlighting and code execution support. (LSP is WIP)
  • hylo-language-server: A prototype Language Server for Hylo, written in Swift.
  • cmakemodules: Common dependencies and utilities that are shared between Hylo projects, such as the Hylo Compiler, SwiftyLLVM and Durian.
