Installation ​

Milo builds from source. The compiler changes often, so a clone you can git pull keeps you current. There are no prebuilt binaries.

Dependencies ​

  • Bun — runs the compiler (TypeScript)
  • LLVM/Clang — backend code generation and linking

Install Bun:

bash
curl -fsSL https://bun.sh/install | bash

Install LLVM — macOS: brew install llvm · Ubuntu/Debian: sudo apt install llvm clang

Clone and run ​

bash
git clone https://github.com/cs01/milo.git
cd milo

The repo ships a milo wrapper — it's just bun run src/main.ts <args>. Run it in place with ./milo, or make milo work from anywhere with one of:

bash
# symlink onto PATH (the wrapper follows the link back to the repo)
sudo ln -s "$PWD/milo" /usr/local/bin/milo

# — or — add the repo to PATH in your shell rc
echo "export PATH=\"$PWD:\$PATH\"" >> ~/.zshrc && source ~/.zshrc

Then, from any directory:

bash
milo run examples/hello.milo
milo build examples/hello.milo -o hello

Stay current with git pull — the symlink/PATH keeps pointing at the repo, so you're always on the latest.

Verify it works ​

bash
milo run examples/hello.milo

You should see:

Hello, Milo!
