Caution

This release contains some breaking changes

1. ParsedIngredient.name is now a list of IngredientText objects, or an empty list no name is identified.

2. The quantity_fractions optional keyword argument has been removed. IngredientAmount.quantity and IngredientAmount.quantity_max return fractions.Fraction objects. Conversion to float can be achieved by e.g.:

   # Round to 3 decimal places
   round(float(quantity), 3)

3. New dependency: floret.

Processing

• Identify where multiple alternative ingredients are given for the stated amount. For example

  # Simple example
  >>> parse_ingredient("2 tbsp butter or olive oil").name
  [
    IngredientText(text='butter', confidence=0.983045, starting_index=2),
    IngredientText(text='olive oil', confidence=0.930385, starting_index=4)
  ]
  # Complex example
  >>> parse_ingredient("2 cups chicken or beef stock").name
  [
    IngredientText(text='chicken stock', confidence=0.776891, starting_index=2),
    IngredientText(text='beef stock', confidence=0.94334, starting_index=4)
  ]

  This is enabled by default, but can be disabled by setting separate_ingredients=False in parse_ingredient. If disabled, the ParsedIngredient.name field will be listing containing a single IngredientText object.

• Set PREPARED_INGREDIENT flag on amounts in cases like

  ... to yield 2 cups ...

• Add convert_to(...) function to IngredientAmount and CompositeIngredientAmount dataclasses to convert the amount to the given units. Conversion between mass and volume is also supported using a default density (density of water) that can be changed.

  >>> p = parse_ingredient("1 8 ounce can chopped tomatoes")
  >>> # Convert "8 ounce" to grams
  >>> p.amount[1].convert_to("g")
  IngredientAmount(quantity=Fraction(5669904625000001, 25000000000000),
                   quantity_max=Fraction(5669904625000001, 25000000000000),
                   unit=<Unit('gram')>,
                   text='226.80 gram',
                   confidence=0.999051,
                   starting_index=1,
                   APPROXIMATE=False,
                   SINGULAR=True,
                   RANGE=False,
                   MULTIPLIER=False,
                   PREPARED_INGREDIENT=False)
  
  >>> # Cannot convert where the quantity or unit is a string
  >>> p.amount[0].convert_to("g")
  TypeError: Cannot convert with string quantities or units.

Model

• Include custom word embeddings as features used by the model. This requires a new dependency of the floret library.
