Libox_computer

A mod that has

Libox laptop

A sort of... luacontroller i guess you could say... with a digistuff touchscreen on top
Inspired by the lwcomputers mod, but without the horrible text inputting and without the filesystem stuff

Libox robot

Like the libox laptop, but has an inventory and can interract with the world

Differences from luacontroller

The sandbox is inside a coroutine
What that means is you can stop the sandbox at any time, and resume from that point
This is how the libox computer handles events
When the sandbox errors or stops, it dies
If the sandbox is not found (say, during a digiline or a gui event) then it will "wake up"
What that means is it will start the sandbox again, mem will still be kept as it was before, you can't kill and start sandboxes in a short time frame, limit is configured by settings
Has the mt-mod's digistuff touchscreen protocol built in
And has even some extra commands
Uses libox, and environment is mostly handled by libox
This means you get extra stuffs to play with and also the sandbox is limited by time, not instructions
Attempts to do coroutine sandboxes securely
But minetest mod security doesn't allow us to weigh the local variables and upvalues of the environment, so libox needs to be a trusted mod for that to work (optional)

Support

mesecons_debug: limiting works fully because this mod uses mesecon queue, no extra things needed
mesecons: only uses it for some utility functions (like mesecon queue and heat), doesn't support mesecons I/O
digilines: the laptop has digilines I/O
luatool: All luatool's features are supported here
wrench: You can pick it up with a wrench
pipeworks: Robot uses pipeworks for inventory automation (receiving/sending items)

This mod uses code from other mods, see LICENSE.md

Todos (not in order)

better code
T E S T S
maybe more robot features (autocrafting :?)

Common troubleshooting

The sandbox doesn't weigh local variables
- You need to add libox to trusted mods for it to expose and use debug.getlocal and debug.getupvalue and use those to weigh the sandbox

What wont be happening

mesecon interraction: i feel like it would be too complicated to rewrite the code to support that at this point
setfenv/getfenv: i am afraid of messing that up... like that could lead to some actual full minetest server control
metatables: you can hide values inside them, oh and getmetatable() is not that fast so weighing things would be slow (needs to be verified actually), and also i just feel like they can be used to do some nasty stuff

What to report as a bug

If it's not covered in the common troubleshooting page and feels un-intended or abusable, then please report it as a bug
If you can hide some data inside userdata, it's a bug
- if you obtain userdata that you can write unlimited data to directly, it's probably a bug
