The ffmpeg of minecraft item transportation: move items (and fluids!) from A to B without any hassle.

A high-level abstraction over the raw CC inventory API. It unifies the many different inventory APIs into a single interface, and said interface includes a wide range of options for quickly and easily setting up pipelines of both the simple and complicated kind. It is powerful, high-throughput, easy to use, flexible, and not very lag-inducing.

As an example use, here's all of the code needed for a super smelter (aka. a furnace array):

startup.lua

shell.openTab([[hopper -sleep 5
  -alias input *chest*
  -alias fuel *chest*
  -alias bucket_return *barrel*
  -alias output *barrel*
  / input *furnace* -not *:lava_bucket -to_slot 1 -to_limit 5 -per_chest
  / fuel *furnace* *:lava_bucket -to_slot 2
  / *furnace* bucket_return *:bucket -from_slot 2 
  / *furnace* output -from_slot 3
]])

Run these two commands on your CC computer to fetch the code:

cd /
wget https://raw.githubusercontent.com/umnikos/hopper.lua/main/hopper.lua

To get the newest bugs and features, fetch the code from the beta branch:

wget https://raw.githubusercontent.com/umnikos/hopper.lua/beta/hopper.lua

Consult the wiki for a tutorial on how to get started. It currently also doubles as documentation.
