Install

For your user, no sudo, on Linux or a Mac. Run the command again to update.

curl -fsSL https://this-site/install.sh | sh

On Linux it installs the app, its menu entry, and CSV files opening with it; start it from your app menu or with brick. It needs GTK 4, which GNOME desktops have; otherwise the installer says how to get it.

On a Mac with Apple Silicon and macOS 14 or later, it puts Brick in your Applications folder, with everything it needs inside. CSV, TSV, and Excel files list Brick under Open With; to open them with Brick by default, select one in Finder, then File > Get Info > Open with > Change All.

To remove it:

curl -fsSL https://this-site/install.sh | sh -s -- --uninstall

Downloads

No release published yet

From the DMG: open it and drag Brick to Applications. Brick isn't notarized by Apple yet, so the first time you open it macOS says it can't check it. On macOS 15 or later, open System Settings > Privacy & Security and click Open Anyway beside Brick's name; on macOS 14, Control-click Brick in Applications and choose Open. Or run this once in Terminal:

xattr -dr com.apple.quarantine /Applications/Brick.app

The install command needs none of this: what curl downloads isn't flagged. Check a download against its sha256 with shasum -a 256 on a Mac or sha256sum on Linux.
