Recipe (recipes/*.yaml)

Simplified Ingredient

= string in a specific format

[amount unit] ingredient name [(note)]

[] means these sections are optional

amount - number
unit - a single word string
name - string with arbitrary content
note - string with arbitrary content, but has to be enclosed in parentheses, otherwise it will be considered to be part of name

for example, valid values are:

1 piece carrot (sliced)
^ amount
  ^---^ unit
        ^----^ ingredient name
               ^-----^ note

200 gram green onion
^-^ amount
    ^--^ unit
         ^---------^ ingredient name

apple
^---^ ingredient name

apple (red)
^---^ ingredient name
      ^---^ note

When amount and unit is not in the string, it is assumed to be 1 piece.

name - MANDATORY, string, name has to be listed in ingredients.yaml if ingredients.yaml exists
amount - number
unit - string, unit has to be listed in units.yaml if units.yaml exists
