Activities/Butialo

Butialo is a user-friendly environment that allows programming of the Butiá in the Lua language. Lua is a simple imperative scripting language but can create sophisticated programs. It is a dynamic language with automatic memory management and is extremely fast. Butialo is a derivative of the Pippy IDE (Python environment provided with the XO), which simplifies the creation of programs for the presence of components connected to the Butiá and offering snippets of code to access them.
