MCDatapacker vs Shulkerscript

MCDatapacker is a Minecraft datapack creator and editor for Linux and Windows. It supports datapacks from Minecraft 1.15 through 1.21.4, with partial support for 1.20.6 through 1.21.4. From its multi-tab interface, users can create or open datapacks, manage files, and edit content. The code editor offers syntax highlighting, error checking for function and JSON files, smart completion for function files, namespaced-ID navigation, and user-defined command syntaxes. Visual editors cover recipes, predicates, loot tables, and item modifiers. Other tools include file and command-usage statistics, raw JSON editing, an advancement-tree viewer, and embedded vanilla datapack files for offline viewing. Dark mode can detect Windows settings automatically. The program is free, with no paid tier required for its core job. Windows users run it from an extracted zip; Linux users run an executable AppImage. The README warns that the program may contain errors and should be used at the user's own risk.

Shulkerscript is a scripting language and command-line tool for creating Minecraft data packs. Its syntax resembles other programming languages and extends beyond `.mcfunction` files: one source file can generate multiple function files callable from Minecraft or other Shulkerscript files. Language features include functions, imports, tags, conditionals, execute blocks, groupings, literal commands, and embedded Lua. Functions marked with `#[tick]` can run every tick, while `#[load]` functions can run when a data pack loads. The CLI builds projects into a `dist` directory, watches for file changes, and can package a compiled project as a ZIP archive. An online playground allows browser use without installation, and an optional official Visual Studio Code extension supplies syntax highlighting and snippets. Installation instructions cover Windows, Linux, and macOS, with options including GitHub releases, cargo-binstall, and building from source with Rust and Cargo. The project is free and open source. The documentation labels the playground and Lua integration as works in progress.
