crafting_calculator.py

This is a generic Python CLI tool for resolving (breaking down) crafting recipes in video games into their base components, to help assemble a shopping list.

I wrote this program because I love building things but dislike the manual resolving into components enough to stop crafting as soon as it gets a bit involved.

• Feedback welcome! (e.g. ping me on Twitter: @ghostlyrics)
• Pull requests with additional games, features or improvements welcome.

installation

Currently this project is in alpha state and not packaged. To install:

• ensure you have Python3 and poetry installed
• check out this repository
• change into this repository
• poetry shell
• poetry install

usage

To calculate a shopping list for crafting, specify an item to craft:

./crafting_calculator.py --game YOUR_GAME YOUR_ITEM
# example: ./crafting_calculator.py --game yonder cobblestone

Result:

You need these items to craft 1 of cobblestone:
stick: 1
stone: 5

The following intermediate items need to be crafted:
constructor's kit: 1

Use quotes when you have an item that contains a space, an apostrophe, etc:

./crafting_calculator.py --game YOUR_GAME "YOUR ITEM"
# example: ./crafting_calculator.py --game yonder "stone tiles"

Result:

You need these items to craft 1 of stone tiles:
clay: 2
fodder: 2
stick: 6
stone: 27

The following intermediate items need to be crafted:
cobblestone: 4
constructor's kit: 6
keystone: 1
mortar: 2

You can optionally craft more than one copy:

./crafting_calculator.py --game YOUR_GAME YOUR_ITEM --amount YOUR_AMOUNT
# example: ./crafting_calculator.py --game yonder cobblestone --amount 7

Result:

You need these items to craft 7 of cobblestone:
stick: 7
stone: 35

The following intermediate items need to be crafted:
constructor's kit: 7

Check the help for all available options:

./crafting_calculator.py --help

writing your own recipes

Recipes are automatically loaded from YAML files in the folder in recipes/ that you ask for with --game. Try writing your own recipes for your own games!

• create a folder in recipes/ (e.g. nyancat)
• add a meta.yml file with information about the game (e.g. Cats and Dogs XI)
  • mandatory keys: title
• add at least one more file with recipes (e.g. example.yml, recipe: yarn)
  • mandatory keys per recipe: name, items
• That's it! Try it: ./crafting_calculator.py --game nyancat yarn

If you want to contribue your recipes to the database, please have a look at the General Style Guide section.

development

• Code in this project is formatted with black, linted with pylint as well as yamllint and type hints are checked with mypy. Black, pylint and yamllint are run automatically via pre-commit.
• Dependency tracking is done with poetry.
• When releases will be available, they will follow semantic versioning and have a changelog.

To get started:

git clone git@github.com:GhostLyrics/crafting_calculator.git
cd crafting_calculator
pre-commit install
poetry shell
poetry install

general style guide

• Keeping the recipes in files that are easy to scan simplifies maintenance. For example, if a game has levels or sections, you could separate by those (carpenter_1_10.yml, smith_apprentice.yml, etc.)
• Keeping the recipe names in lowercase helps keep things simple.
• Keeping the recipes sorted alphabetically in the recipe files makes it easier to update things.
