Class Method Details

.parse(filepath, **options) ⇒ EPUB

Parse an EPUB file

Examples:

EPUB::Parser.parse('path/to/book.epub') # => EPUB::Book object
class MyBook
  include EPUB
end
book = MyBook.new
parsed_book = EPUB::Parser.parse('path/to/book.epub', :book => book) # => #<MyBook:0x000000019760e8 @epub_file=..>
parsed_book.equal? book # => true
book = EPUB::Parser.parse('path/to/book.epub', :class => MyBook) # => #<MyBook:0x000000019b0568 @epub_file=...>
book.instance_of? MyBook # => true

Parameters:

  • filepath (String)
  • options (Hash) —

    the type of return is specified by this argument. If no options, returns Book object. For details of options, see below.

Options Hash (**options):

Returns:
