Decker

Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior. You can try it in your web browser right now. Decker builds on the legacy of HyperCard and the visual aesthetic of classic MacOS https://beyondloom.com/decker/

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.

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

Every deck is a toolkit of reusable parts that can be harvested and repurposed for another project.

Decker is command-line friendly: when built from source, it comes with Lilt, a standalone Lil interpreter which can (among other things) read, write, manipulate, and even execute Decker documents "headlessly".

Decks are stored in a line-oriented text format which interoperates well with existing source control tools like Git and SVN.
