Craft Calc

Craft Calc is a Domain Specific Language (DSL) for Calculating Materials Needed when Crafting

When given a set of crafting rules (via editing the file named "rules.txt"), this program can calculate the materials needed for crafting your target (described in the file named "input.txt").

Demo

rules.txt

basic_materials: Wood, Coal

WoodenPlank = Wood
Stick = WoodenPlank * 2
Torch = Coal + Stick

input.txt

(Torch * 10) % basicMaterials

output

(Torch * 10) % basicMaterials
= Wood * 20 + Coal * 10
