history
Project history and usage
Decker is a HyperCard-inspired multimedia platform for creating and sharing interactive documents with sound, images, hypertext, drawing, widgets, and scripted behavior. The package includes the native `decker` app and `lilt`, a command-line Lil interpreter.
Project history
The public GitHub repository was created in October 2022, and the official homepage presents Decker as carrying forward HyperCard's simplicity and classic MacOS aesthetic while adding quality-of-life improvements. The README describes both Web-Decker, distributed as a single self-contained HTML application, and Native-Decker, a C application built with SDL.
Adoption history
Decker is distributed through its official website, GitHub source, Itch.io binary releases for macOS and Windows, and package managers such as Homebrew and Nix. Its community footprint includes Itch.io discussion forums and recurring Decker-themed game jams.
How it is used
Users can author decks interactively in the browser or native app, export standalone HTML documents, or use Lilt to inspect, manipulate, execute, and package decks from scripts. Decker's text-based deck format is intentionally friendly to source control, which makes it attractive to users who treat creative artifacts like editable project files.
Why package nerds care
Decker is interesting to package people because it combines a GUI authoring tool, a browser distribution, a tiny scripting language, and a command-line interpreter in one source tree. It also reflects a retrocomputing-inspired software culture where constraints, portability, local-first documents, and inspectable file formats are part of the product.
