org-shoplist

An extension to emacs for operating on org-files who provide food-recipes. It's meant to generate shopping lists and make eating-plans. (We talk about delicious food — nothing technical).

Getting Started

Installation

Melpa: M-x package-install ENT org-shoplist ENT

Use-package with straight:

(use-package org-shoplist
  :straight (org-shoplist :type git :host github :repo "lordnik22/org-shoplist"))

Alternatively you can clone this project and add it to the load-path in your init-file:

(add-to-list 'load-path "~/.emacs.d/elisp/org-shoplist")
(require 'org-shoplist)

Your first Shoplist

• Create a new file or use one of your org-agenda-files
• Add a recipe (See Recipes for some examples)
• Mark your recipe (org-headers) for buying with "TOBUY" (defined in org-shoplist-search-type)
• Press M-x org-shoplist ENT

Ingredients

Enclose the ingredients with org-shoplist-ing-start-char and org-shoplist-ing-end-char. Simple examples for ingredients: (#200g nuts#), (#1 nut#), (#1 big nut#)

Structure:

1. org-shoplist-ing-start-char (default: '(#')
2. Number (amount)
3. optional unit
4. space as separator
5. followed by any name which can have ANY character expect org-shoplist-ing-start-char or org-shoplist-ing-end-char.
6. org-shoplist-ing-end-char (default: '#)')

Unit

For calculating with units the calc-package is used. You can use any unit by default that is listed in the calc-unit-table (M-x calc-view-units-table ENT).

For additional units:

• If you are lazy just set (M-x customize-variable ENT org-shoplist-auto-add-unit)
• else see Personal Units

Customization

Enclosing

Also everything that is enclosed with org-shoplist-ing-start-char or org-shoplist-ing-end-char and has a space will be handled as ingredient. org-shoplist-ing-start-char and org-shoplist-ing-end-char can be the same char or they could even be string.

Personal Units

Unfortunately a unit can't be any character. You are well advised to just use A-Z and a-z. You can add the definition of your personal units to the variable org-shoplist-additional-units.

An example, adding the german equivalent of Tablespoon(tbsp):

(setq org-shoplist-additional-units '((tl "1 tbsp" "Teelöffel"))
;;First is the unit specifier (case-sensitive (is a symbol))
;;Second is the definition. In this example 1tl is 1tbsp.
;;Third is a Description (can be a empty String)

For "ground-units" (a unit that can't be expressed by a finner/lower unit) use nil as definition: ((myUnit nil "*My Special unit")) or just let org-shoplist add these definitions for you by setting org-shoplist-auto-add-unit.

Circular definitions lead to errors: ((myUnit "myUnit" "*My Special unit"))

Beware when using relative units like cups, that all cups get aggregated together when org-shoplist-aggregate is non-nil (default).

Recipes

A recipe is a group of ingredients. You pretty much can write what ever you want. Important is that you format your ingredients properly (See Ingredients).

You can change the enclosing of the ingredients, (See Enclosing).

A "marked recipe" is a org-header which will be detected by org-shoplist. How they are detected is defined by org-shoplist-search-type(default: (keyword "TOBUY")). Example using the default: * TOBUY Älpämagerone

Example

• As a list:

* TOBUY Älpämagerone
- (#250ml Rahm#)
- (#1 Zwiebel#)
- (#250g Magrone#)
- (#250g Emmentalerkäse#)

• As a german description:

* TOBUY Älpämagerone 2
Nimm (#250ml Rahm#) und (#1 Zwiebel#) vermische es mit (#250g Magrone#) und (#250g Emmentalerkäse#).
Danach 15min köcheln lassen.

You can also have nested headers (See Explicitness).

Factor

A recipe can have a factor-property. With the factor-property you can define the amount of people or portion the recipe is written for. The property is controllable with (org-shoplist-factor-up) and (org-shoplist-factor-down). This property affects not only ingredients of the current header-level but also all ingrdients in the underlying tree. Headers with no ingredients aren't affected and Explicitness is ignored for these functions.

Example:

* TOBUY Älpämagerone
  :PROPERTIES:
  :FACTOR:   2
  :END:
- (#500ml Rahm#)
- (#2 Zwiebel#)
- (#500g Magrone#)
- (#500g Emmentalerkäse#)

Customization

org-shoplist-inital-factor defines the default factor when no factor-property is set on the header.

With org-shoplist-factor-property-name you can define the property-name to your taste.

Shopping List

A shopping list is a collection of ingredients, generated from the marked recipes. The marked recipes are read from org-shoplist-files which by default is the same as org-agenda-files.

You can generate a shopping list by pressing M-x org-shoplist RET in your org-file where recipes with the org-shoplist-keyword are present.

With C-u M-x org-shoplist ENT you can pass an other formatter-function, also see Format.

Customization

Search type

org-shoplist-search-type defines how recipes are detected.

There exist three strategies:

• keyword: Detect org-headers for buying which are marked with specified keyword.
• tag: Detect org-headers for buying which have the specified tag plus are marked with one not-done-keyword.
• keyword+tag: Detect org-headers for buying which are marked with specified keyword plus have the specified tag.

Explicitness

There are two behaviors depending on org-shoplist-explicit-keyword (by defualt it's nil).

When nil, all ingredients of nested headers are included.

* TOBUY Älpämagerone
- (#250g Magrone#)
** Part 1
- (#1 Zwiebel#)
** Part 2
- (#250ml Rahm#)
- (#250g Emmentalerkäse#)

When non-nil, only the headers with the org-shoplist-keyword are included in the shopping list. In this example we have a cream with flakes and chocolate but without vanilla.

* TOBUY Cream
- (#250g flakes#)
** TOBUY with chocolate
- (#100g chocolate#)
** with vanilla
- (#250ml vanilla#)

Aggregation

You can turn off aggregation by setting org-shoplist-aggregate to nil.

Format

The format is established by a function which takes a shopping list as it's arguments. The defualt format is defined by org-shoplist-default-format. If you are interested in writing your own shoppinglist-formating-function, you may find it helpful reading the built-in formatter-functions in org-shoplist.el.

Following formats are provided in this package:

• org-shoplist-shoplist-as-table
• org-shoplist-shoplist-as-todo-list
• org-shoplist-shoplist-as-recipe-list

You can try them out by calling org-shoplist with C-u. Example with org-shoplist-shoplist-as-recipe-list: C-u M-x org-shoplist ENT org-shoplist-shoplist-as-recipe-list ENT

Other Customization

Press M-x customize-group org-shoplist ENT for all custom variables.
