CraftOS-PC is a fantasy terminal that allows you to write and run programs inside an ‘80s-style text console.

CraftOS-PC emulates the popular mod "ComputerCraft" for an award-winning block building video game, which adds programmable computers to the game using the Lua programming language. CraftOS-PC takes this experience outside the game to allow you to run the same programs anywhere you go.

CraftOS-PC provides a set of functions (called APIs) that make it super easy to do simple tasks such as write text to the screen, read files, and more. The simplicity of these functions makes CraftOS-PC great for new programmers, but their power makes it possible to write all sorts of complex programs with less code.

If you aren’t ready to write programs yet, there’s already a large number of programs for ComputerCraft that will work in CraftOS-PC, ranging from simple games to whole graphical operating systems. These can be downloaded through the built-in Pastebin and GitHub Gist clients.
