-- This program monitors work requests for the Minecolonies Warehouse and
-- tries to fulfill requests from the Refined Storage network. If the
-- RS network doesn't have enough items and a crafting pattern exists, a
-- crafting job is scheduled to restock the items in order to fulfill the
-- work request.  The script will continuously loop, monitoring for new
-- requests and checking on crafting jobs to fulfill previous requests.

-- The following is required for setup:
--   * 1 ComputerCraft Computer
--   * 1 or more ComputerCraft Monitors (recommend 3x3 monitors)
--   * 1 Advanced Peripheral Colony Integrator
--   * 1 Advanced Peripheral RS Bridge
--   * 1 Chest or other storage container
-- Attach an RS Cable from the RS network to the RS Bridge. Connect the
-- storage container to the Minecolonies Warehouse Hut block. One idea is
-- to set up a second RS network attached to the Warehouse Hut using an
-- External Storage connector and then attach an Importer for that network
-- to the storage container.

-- THINGS YOU CAN CUSTOMIZE IN THIS PROGRAM:
-- Line 59: Specify the side storage container is at.
-- Line 66: Name of log file for storing JSON data of all open requests.
-- Lines 231+: Any items you find that should be manually provided.
-- Line 373: Time in seconds between work order scans.

----------------------------------------------------------------------------
-- INITIALIZATION
----------------------------------------------------------------------------

-- Initialize Monitor
-- A future update may allow for multiple monitors. This would allow one
-- monitor to be used for logging and another to be used for work requests.
local monitor = peripheral.find("monitor")
if not monitor then error("Monitor not found.") end
monitor.setTextScale(0.5)
monitor.clear()
monitor.setCursorPos(1, 1)
monitor.setCursorBlink(false)
print("Monitor initialized.")

-- Initialize RS Bridge
local bridge = peripheral.find("rsBridge")
if not bridge then error("RS Bridge not found.") end
print("RS Bridge initialized.")

-- Initialize Colony Integrator
local colony = peripheral.find("colonyIntegrator")
if not colony then error("Colony Integrator not found.") end
if not colony.isInColony then error("Colony Integrator is not in a colony.") end
print("Colony Integrator initialized.")

-- Point to location of chest or storage container
-- A future update may autodetect where the storage container is and error
-- out if no storage container is found.
local storage = "left"
print("Storage initialized.")

-- Name of log file to capture JSON data from the open requests.  The log can
-- be too big to edit within CC, which may require a "pastebin put" if you want
-- to look at it.  Logging could be improved to only capture Skipped items,
-- which in turn will make log files smaller and edittable in CC directly.
local logFile = "RSWarehouse.log"

-- FUNCTIONS
----------------------------------------------------------------------------

-- Prints to the screen one row after another, scrolling the screen when
-- reaching the bottom. Acts as a normal display where text is printed in
-- a standard way. Long lines are not wrapped and newlines are printed as
-- spaces, both to be addressed in a future update.
