Transposer

Less posing, more rights
The transposer moves items and fluids between containers next to it. This includes chests, cauldrons and machines supporting automation. Moving to or from an unblocked side drops items into the world and picks them up again, or fills with and drains fluids.
It can be controlled using both the high-level API and the mid-level API. For example:
local d = require("devices")
local t = d:find("transposer")
print(t:moveItems("north", 0,
"south", 0, 64))

API

Programs control the transposer through the transposer device. See the transposer device reference for its methods.
