How do I install Line CLI on a Mac?

Open Terminal and run:

curl -fsSL https://install.clatterlabs.xyz/line | sh

What happens#

1. The script detects your Mac's chip (Intel or Apple silicon).
2. It downloads the matching build and checks its SHA-256 checksum.
3. It installs line to ~/.line/bin/line and removes macOS's quarantine flag from it.
4. It adds ~/.line/bin to your PATH in your shell profile (~/.zshrc for zsh, the default on modern macOS).

Then#

1. Restart Terminal, or run the export PATH=… line the installer prints.
2. line --version
3. line login
4. cd your-project && line
