inflector.classify("books") # => "Book"

inflector.constantize("Dry::Inflector") # => Dry::Inflector
inflector.dasherize("dry_inflector") # => "dry-inflector"
inflector.underscore("dry-inflector") # => "dry_inflector"
inflector.humanize("dry_inflector") # => "Dry inflector"
inflector.humanize("author_id") # => "Author"
inflector.tableize("Book") # => "books"
inflector.foreign_key("Book") # => "book_id"
inflector.ordinalize(1) # => "1st"
inflector.ordinalize(2) # => "2nd"
inflector.ordinalize(3) # => "3rd"

Custom inflection rules
require "dry/inflector"
inflector = Dry::Inflector.new do |inflections|
inflections.plural "virus", "viruses" # specify a rule for #pluralize
inflections.singular "thieves", "thief" # specify a rule for #singularize
inflections.uncountable "dry-inflector" # add an exception for an uncountable word
end
inflector.pluralize("virus") # => "viruses"
inflector.singularize("thieves") # => "thief"
inflector.pluralize("dry-inflector") # => "dry-inflector"
