blueprint.cr

Factorio blueprint parsing library written in Crystal. Plans to eventually include a blueprint builder API similar to that of JSON::Builder.

Installation

Add this to your application's shard.yml:

dependencies:
  blueprint:
    github: maxpowa/blueprint.cr

Usage

# Simple script which demonstrates some usage of Blueprint.parse
# Will output counts for each entity included in the blueprint
require "blueprint"

puts "Paste your blueprint string: "
blueprint_str = gets.not_nil!           # Take user input 

result = Blueprint.parse(blueprint_str) # Parse to a Blueprint::Blueprint or Blueprint::Book

required_items = {} of String => Int32

if (result.is_a?(Blueprint::Blueprint)) # Check if its a Blueprint::Blueprint
  result.entities.not_nil!.map do |entity|
    current_count = required_items[entity.name]? || 0
    required_items[entity.name] = current_count + 1
  end
end

puts required_items
