📅 Calendar Tetris

Play Tetris in Apple Calendar.

5-Column mode with HUD off. Run with npx calendar-tetris --5-col --no-hud

Run

Run the CLI and follow the instructions to get started. Calendar Tetris requires macOS.

npx calendar-tetris

Control Calendar Tetris by entering keys into your terminal.

[!WARNING] Calendar Tetris requires permission to control your calendar. It creates and uses its own calendars and should never affect your existing calendars. Nonetheless, if you have important information in your calendar, proceed with caution.

Modes

Default mode of 10 columns with HUD. Run with npx calendar-tetris

--no-hud

You can hide the HUD (Hold, Up Next, and the header) with the --no-hud flag.

npx calendar-tetris --no-hud

--5-col

You can play a modified 5-column version of Tetris with the --5-col flag. It has the I (3-cell), Domino (2-cell), L, T, S, and Z pieces. This mode has better performance since there are fewer events being created and edited.

npx calendar-tetris --5-col

Cleanup

Calendar Tetris should automatically clean up any Calendars created during the game.

However, if the process was force-quit before automatic cleanup completed, run:

npx calendar-tetris cleanup

Cleanup should only ever remove game calendars created by Calendar Tetris. You can also safely manually perform cleanup by deleting calendars whose names start with __CALENDAR_TETRIS__*.

How Does it Work?

Calendar Tetris controls your calendar with AppleScript and EventKit. By creating calendars for every color needed, Calendar Tetris can create and edit events in the proper-colored calendars to turn events into Tetris blocks falling down your calendar.

Development

npm install
npm test

The test suite compiles every AppleScript without launching or contacting Calendar.
