wordcraft

WordCraft is an open-source, clean-room reimplementation of Microsoft Word, built from the ground up in pure Rust by the ArtCraft team. It delivers a full-featured word processor built around the desktop editing workflow millions of users rely on—complete with the ribbon interface, document styles, tables, references, track changes, and mail merge—without carrying decades of legacy software overhead. Dual-licensed under MIT and Apache-2.0, the application targets high-performance desktop execution alongside modern web browsers. ### Core Architecture and Platform Support Engineered entirely in pure Rust, WordCraft relies on Rust's strong memory safety guarantees and deterministic execution model to deliver fast document layout, rendering, and text editing capabilities. The codebase is cross-platform by design: it compiles natively for macOS, Windows, Linux, and BSD architectures, while also targeting WebAssembly (WASM) to run directly inside browser runtimes. The engine provides direct read and write interoperability with standard `.docx` files. WordCraft presents a modular document layout tree and state engine capable of handling complex visual and structural elements: * Ribbon Interface & Formatting Engine: Combines context-aware toolbar tabs with a live Styles gallery that previews typography presets (such as Normal, Heading 1, Title, and Subtitle) in real time. * Structural Document Navigation: Integrates a dedicated Navigation pane that parses document heading hierarchies for structural overview and quick jumping across multi-page documents. * Layout and Editing Suite: Includes native support for track changes, mail merge generation, table structures, cross-references, and visual page rulers for margin and indentation adjustments. ### Programmatic Control: CLI and MCP Integration Beyond standard user-facing GUI features, WordCraft is architected for programmatic automation. It exposes driver interfaces for both standard command-line (CLI) execution and the Model Context Protocol (MCP). This design allows software agents and automated scripts to drive the document engine directly. External tools can manipulate document structures, inspect formatting tree models, apply changes, and generate formatted `.docx` output without human interaction or GUI overhead. ### Deployment Targets Because the project is written in pure Rust with explicit cross-platform support, compiling WordCraft follows standard Rust toolchain targets across native desktop platforms (macOS, Windows, Linux, BSD) and web runtimes via WebAssembly. By combining native system performance, native `.docx` read/write capabilities, cross-platform portability, and explicit agent control via MCP, WordCraft offers a fresh, technical take on open-source document processing.
