Bukkit

This is an updated version of AutoReloader.

I take no credit for this; the credit goes to Uristqwerty who created this awesome plugin.

The Bukkit forums thread for this plugin is located here.

Version: v0.5

MoreAutoReloader allows furnaces and dispensers to be reloaded from adjacent chests with a redstone current.

According to the original author of AutoReloader:

Place a furnace on a diamond block.
Give the block a redstone current. Every time the diamond block gets a current change, the furnace will look on all four sides of itself for chests, and react depending on the content's of its inventory boxes(the ones on the UI in-game) and the type of block below the chest.
If it finds a chest on an Obsidian block, and its fuel box is empty, it will get an item from the chest and move it there.
If it finds a chest on a Lapis Lazuli block, and its input box is empty, it will get an item from the chest and move it there.
If it finds a chest on a Gold block, and its output box is not empty, it will move its output to the chest.

Because it can work with double chests, it is possible to make a bit of a production line, where the output of one furnace is used as the input or fuel for another.

(Furnace on the right produces charcoal to fuel the furnace on the left)

The original plugin also had code to automatically fill dispensers; it was disabled due to a problem in CraftBukkit. Apparently, the problem had been fixed and the code is now re-enabled. To use, put the dispenser on the diamond block and put the chest to supply the dispenser on a Lapis block.

Version 0.4 introduces support for brewing stands: The ingredient is taken from the chest above obsidian, and potions are loaded from the Lapis chest and output into the gold chest.

The left brewing stand produces potions which is used as the source potion for the right brewing stand.

Configuration:
In the configuration, you can enable or disable reloading of furnaces/dispensers/brewing stands, and change the blocks that indicate the input, output, fuel chests or the container to be reloaded. The configuration is located at plugins/MoreAutoReloader/config.yml. A list of valid block names can be found at here

The default config:

material:
    container: DIAMOND_BLOCK
    input: LAPIS_BLOCK
    output: GOLD_BLOCK
    fuel: OBSIDIAN
enabled:
    furnace: true
    dispenser: true
    brewing-stand: true
