🏢 TunaOS GTK Office Suite

A complete, native office suite for GNOME — built in Rust and GTK 4 with Libadwaita. Three apps, one shared scaffold, all distributed as Flatpaks.

✨ Why a Rust Office Suite?​

Most Linux office suites are either:

  • Monolithic C++ (LibreOffice) — powerful but heavy, slow to start
  • Web-based (Google Docs, OnlyOffice) — not native, requires a browser
  • Proprietary (WPS Office) — not open source

TunaOS's office suite is different:

  • 🦀 Rust — memory-safe, fast, and modern
  • 🎨 GTK 4 + Libadwaita — native GNOME look and feel
  • 📦 Flatpak — sandboxed, auto-updating, dependency-free
  • 🔗 Shared scaffold — common chrome, WebKit bridge, and file I/O via suite-common
  • 🧩 Interchangeable engines — each app uses best-in-class libraries under the hood

🚀 Quick Install​

Add the TunaOS Flatpak remote and install any app:

flatpak remote-add tuna-os oci+https://tuna-os.github.io/flatpak-index

# Install all three
flatpak install tuna-os io.github.hanthor.tables
flatpak install tuna-os io.github.hanthor.decks
flatpak install tuna-os net.codelogistics.letters

📝 Letters (Word Processor)​

A distraction-free writing experience with:

  • pandoc — universal document conversion
  • weasyprint — PDF export with CSS styling
  • DOCX, ODT, Markdown, and HTML support

Letters is a hard fork of the original Letters by Satvik Patwardhan, maintained as part of the TunaOS office suite.

🛠️ Contributing​

All three apps are written in Rust with GTK 4 and Libadwaita bindings. They share the suite-common scaffold and suite-common-rust libraries.

Good first contributions:

  • Add a unit test
  • Improve error handling
  • Fix an accessibility issue
  • Translate UI strings
