Sugar is written in Python with a variety of open source packages. Programming in the Sugar environment requires a basic understanding of both the Sugar User Interface, supporting third-party packages, and built-in Sugar packages.

Traditional software packages are built against Application Programming Interfaces. Sugar runs Activities instead of applications, but from a developer's point of view, it's the same thing.

Third Party Packages

  • Avahi - Network Discovery Service
  • Matchbox - Graphical Windows Manager
  • Xul - XML User Interface Language (aka gecko and other identity challenged projects)
  • Pango - GTK package for text rendering
  • ATK - GNOME Accessibility Toolkit
  • gstreamer - media player
  • X Window System - the tried-and-true ancient X11 display libraries
