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. ### Timeline - 2022: Public GitHub repository created. - 2026: VERSION file reports 1.67 in the main branch. - 2026: Official site advertised Decker Fantasy Camp for July 2026. ### Related projects - Decker is explicitly related to HyperCard and to Lil/Lilt, its built-in scripting language and terminal interpreter. Its homepage also positions it near zine tools, adventure-game builders, visual notebooks, and small creative programming environments. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** decker - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - decker: normalized package name match | nixpkgs package indexes: pkgs/by-name/de/decker/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - zypper - decker - 1.60-1.5: normalized package name match | openSUSE Tumbleweed package metadata: decker from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | A multimedia sketchpad | http://beyondloom.com/decker/ ## Related links - [Secret-risk packages](https://pkg.so/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Productivity CLI packages](https://pkg.so/productivity-cli-packages/) - Matched curated productivity category metadata from av.db. - [sdl2-compat](https://pkg.so/brew/sdl2-compat/) - Runtime dependency declared by Homebrew. - [fcitx-remote-for-osx](https://pkg.so/brew/fcitx-remote-for-osx/) - Shares pkgdb curated category or tags: cli, productivity, scripting. - [tmux](https://pkg.so/brew/tmux/) - Shares pkgdb curated category or tags: cli, productivity. - [vim](https://pkg.so/brew/vim/) - Shares pkgdb curated category or tags: cli, productivity. - [himalaya](https://pkg.so/brew/himalaya/) - Shares pkgdb curated category or tags: cli, productivity. - [yazi](https://pkg.so/brew/yazi/) - Shares pkgdb curated category or tags: cli, productivity. - [emacs](https://pkg.so/brew/emacs/) - Shares pkgdb curated category or tags: cli, productivity. - [zellij](https://pkg.so/brew/zellij/) - Shares pkgdb curated category or tags: cli, productivity. - [aspell](https://pkg.so/brew/aspell/) - Shares pkgdb curated category or tags: cli, productivity. - [ctpv](https://pkg.so/brew/ctpv/) - Both packages work with overlapping file formats or content types.
