drip, running in your browser

This page loads drip's own engine, DripCore, compiled from the same Swift sources to WebAssembly. Type a drip command: the engine parses it, resolves the card, wraps the text and springs the island out of the notch. Send a few at once and they stack, up to three, each dropping out of the one above. The page only paints what the engine computes, frame by frame.

• Real: the command line (swift-argument-parser), presets, config, flags, drip run's title and timing, line wrapping, the island's sizes, every spring and the liquid outline traced by marching squares.
• Drawn by the page: the paint. Icons stand in for SF Symbols, fonts are the browser's system font, and there is no sound.
• Stacks: cards sent while others show stack below them, chained (each drops out of the card above) or pushed (DRIP_STACK=push drip …, each drops out of the notch and pushes the others down). The engine places them, holds a fourth until there is room, and stops every countdown while the pointer is on a card.
• Not here: other positions and styles (every card is a notch card), cards replaced in place, history.
