Decker, a modern tool in the footsteps of HyperCard

Decker builds on the legacy of HyperCard and the visual aesthetic of classic MacOS. It retains the simplicity and ease of learning that HyperCard provided, while adding many subtle and overt quality-of-life improvements, like deep undo history, support for scroll wheels and touchscreens, more modern keyboard navigation, and bulk editing operations.

Anyone can use Decker to create E-Zines, organize their notes, give presentations, build adventure games, or even just doodle some 1-bit pixel art. The holistic “ditherpunk” aesthetic is cozy, a bit nostalgic, and provides fun and distinctive creative constraints.

As a prototyping tool, Decker encourages embracing a sketchy, imperfect approach. Finished decks can be saved as standalone .html documents which self-execute in a web browser and can be shared anywhere you can host or embed a web page. Decker also runs natively on MacOS, Windows, and Linux.

For more complex projects, Decker features a novel scripting language named Lil which is strongly influenced by both Lua, an imperative language popular for embedding in tools and game engines, and Q, a functional language in the APL family used with time-series databases. Lil is easy to learn and conventional enough not to ruffle any feathers for users with prior programming experience, but also includes pleasant surprises like implicit scalar-vector arithmetic and an integrated SQL-like query language.
