# LuPI2
|
||||
Second attempt at Lua based operating system, primarily aimed at RaspberryPi, but with ambition to support other boards as well. The main motivation is
|
||||
fact that GNU/Linux + python solution isn't allays the best for people that haven't been programming ever, and Lua in one of the simplest, most
|
||||
intuitive languages. It has only 6 types, very simple syntax, yet supports many advanced mechanisms.
|
||||
|
||||
Idea
|
||||
-----
|
||||
Design of system APIs is heavily influenced by [OpenComputers](https://github.com/MightyPirates/OpenComputers) minecraft mod. Some Lua code parts are
|
||||
actually copied from there(all of the code is under the MIT License). Main advantage of the API is that it's event/component based, which provides great
|
||||
level of abstraction. Custom components can be created and used with very little effort, being event-based simplifies code further, providing one unified
|
||||
queue for events instead of multiple ways of handling them.
|
||||
```lua
|
||||
local component = require("component")
|
||||
|
||||
--Create virtual LED component using built-in GPIO component
|
||||
local led = {}
|
||||
led.toggle = function() component.gpio.togglePin(27) end
|
||||
component.register(nil, "LED", led)
|
||||
|
||||
--Blink the LED
|
||||
while true do
|
||||
os.sleep(1)
|
||||
component.led.toggle()
|
||||
end
|
||||
```
|
||||
|
||||
Implementation
|
||||
-----
|
||||
On the low-level side LuPI will run on very stripped-down version of Linux kernel as init, it will be the only binary executable in system. Kernel will
|
||||
only provide hardware drivers and abstract some of the things. Entire userspace is meant to be done using Lua. Security isn't the primary goal but still
|
||||
needs to be considered.
