Module: RecipeScrapers::Parsers::Nutrients

Defined in:
lib/recipe_scrapers/parsers/nutrients.rb

Overview

The bundled parser of nutrient values. It reads the first number and the word after it, and drops text in parentheses. Mass and energy units are written as symbols, so "grams" and "г" become "g" and "calories" becomes "kcal".

Examples:

RecipeScrapers::Parsers::Nutrients.call("12.5 grams").to_h # => { name: nil, unit: "g", amount: 12.5 }
