## DESCRIPTION:
a generic EPUB parser/generator library.
## FEATURES/PROBLEMS:
* GEPUB::Book provides functionality to create EPUB file, and parsing EPUB files
* Handle every metadata in EPUB2/EPUB3.
* See [issues](https://github.com/skoji/gepub/issues/) for known problems.
If you are using GEPUB::Builder and do not like its behaviour(e.g. the block inside is evaluated as inside the Builder instance), please consider using GEPUB::Book directly.
## SYNOPSIS:
### Example
```ruby
require 'rubygems'
require 'gepub'
book = GEPUB::Book.new
book.primary_identifier('http://example.jp/bookid_in_url', 'BookID', 'URL')
book.language = 'ja'
book.add_title 'GEPUBサンプル文書',
title_type: GEPUB::TITLE_TYPE::MAIN,
lang: 'ja',
file_as: 'GEPUB Sample Book',
display_seq: 1,
alternates: {
'en' => 'GEPUB Sample Book (Japanese)',
'el' => 'GEPUB δείγμα (Ιαπωνικά)',
'th' => 'GEPUB ตัวอย่าง (ญี่ปุ่น)' }
# you can do the same thing using method chain
book.add_title('これはあくまでサンプルです', title_type: GEPUB::TITLE_TYPE::SUBTITLE).display_seq(1).add_alternates('en' => 'this book is just a sample.')
# use arguments
book.add_creator '小嶋智',
display_seq:1,
alternates: { 'en' => 'KOJIMA Satoshi' }
book.add_contributor '電書部',
display_seq: 1,
alternates: {'en' => 'Denshobu'}
book.add_contributor 'アサガヤデンショ',
display_seq: 2,
alternates: {'en' => 'Asagaya Densho'}
# you can also use method chain
book.add_contributor('湘南電書鼎談').display_seq(3).add_alternates('en' => 'Shonan Densho Teidan')
book.add_contributor('電子雑誌トルタル').display_seq(4).add_alternates('en' => 'eMagazine Torutaru')
imgfile = File.join(File.dirname(__FILE__), 'image1.jpg')
File.open(imgfile) do
|io|
book.add_item('img/image1.jpg',content: io).cover_image
end
# within ordered block, add_item will be added to spine.
book.ordered {
book.add_item('text/cover.xhtml',
content: StringIO.new(<<-COVER)).landmark(type: 'cover', title: 'cover page')
the first page
CHAP_ONE book.add_item('text/chap1-1.xhtml').add_content(StringIO.new(<<-SEC_ONE_ONE)) # do not appear on table of contentsthe second page
SEC_ONE_ONE book.add_item('text/chap2.xhtml').add_content(StringIO.new(<<-CHAP_TWO)).toc_text('Chapter 2')the third page
CHAP_TWO # to add nav file: # book.add_item('path/to/nav').add_content(nav_html_content).add_property('nav') } epubname = File.join(File.dirname(__FILE__), 'example_test.epub') # if you do not specify your own nav document with add_item, # simple navigation text will be generated in generate_epub. # auto-generated nav file will not appear on spine. book.generate_epub(epubname) ``` * [examples in this repository](https://github.com/skoji/gepub/tree/master/examples/) ## INSTALL: * gem install gepub
