Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior. It draws strong influence from HyperCard, as well as more modern "no-code" or "low-code" creative tools like Twine and Bitsy. If Jupyter Notebooks are a digital lab notebook, think of Decker as a stack of sticky notes.
Decker provides a scripting language called Lil, which is easy to learn but highly expressive. Simple things are easy, and complex things are possible.
Decker understands tabular data. You can use Lil to perform SQL-like queries on tables and import or export CSV files.
