Activity Development Alternatives

Python 

This is the canonical way to create activities. See API Reference.

Squeak 

Squeak is a Smalltalk environment pre-installed on the XO. See Squeak-based activities.

C 

Any X11 program can be made into an activity. See Low-level Activity API.

Non-Standard Alternatives

These require additional libraries to be loaded, and as such, not recommended.

Qt 

A library for creating XO activities using C++ and Qt is under development by Ark Linux. See the Qt page for details.

Mono 

It is possible to use Mono to write an xo activity, too. See Mono page for further details.
