Pattern Crafter (Compacter)
by Unfamily
Pattern Crafter adds crafting machines that run recipes from patterns, with a second, upgradeable Improved Pattern Crafter for larger chains.
What it does
A Pattern Crafter takes ingredients from 27 input slots and places results in 9 output slots, and it works with hoppers and other item transport. Each machine holds one or more patterns: a pattern assigns letters to items, and the machine crafts using the letter layout it was given. Shaped, shapeless or both kinds of recipe can be chosen per pattern. Redstone modes (ignore, low, high, pulse and disabled) control when a machine runs, and a common config file lets the two machine types be tuned separately.
The Improved Pattern Crafter accepts upgrade slots for RF energy, extra patterns, faster crafting and logic modules, and it supports filters on inputs and outputs. Input filters are set per letter, while output filters blacklist certain results. Power comes from the default energy setting or from RF energy supplied by cables and compatible generators, and the optional Iskandert Utilities mod can supply upgrade modules. Both blocks appear in the Redstone creative tab, and the game or server must be restarted after the config is changed. The mod is released under the MIT License and is open source.
Key features

The Improved Pattern Crafter takes upgrades for more patterns, faster crafting and RF energy, and can add logic modules.
Input and output filters
Input filters are set per letter, and output filters blacklist results so unwanted items are not produced.
