Furst

Functional first memory safe language based on LLVM.

Getting Started

Nix (recommended)

Requires Nix with flakes enabled.

# full environment (frontend + backend)
nix develop

# frontend only (F#/dotnet + protobuf)
nix develop .#frontend

# backend only (clang, cmake, LLVM, etc.)
nix develop .#backend

The default shell provides a publish command that builds everything into build/.

The backend shell provides helper commands: configure, build, test, fmt, lint, clean, rebuild, cycle, gen-fixtures, preflight. Run any shell to see usage.

Legacy

./build.ps1

Pulls LLVM into deps/ and runs cmake.
