Blog-o-Book, aka BOB, is a framework to publish a book as a webpage. Why not just publish it as PDF or static html? BOB has a number of helper methods makes publishing and reading easier, like automatic table of contents, comments, last read chapter or new chapters list. You can browse and read it as a book or like a blog, browsing the articles, adding a comments, linking to selected paragraphs. It is all up to you.
There is a free book Ruby for Admins, which uses BOB. It is for all Sysadmins, DBAs and other Unix power users to help them in their daily duties.
BOB is based on Ruby on Rails. You will need Ruby (see rubyforadmins.com/installation to learn how to install Ruby with Rbenv), version at least 2.0 and Rails 4.1.1.
gem install bundler rbenv rehash gem install rails git clone firstname.lastname@example.org:grych/bob.git cd bob bundle install vi config/database.yml rake db:migrate rake db:reload_chapters rails s
Every chapter is a single file in chapters/ directory. Every file must have unique numeric prefix and “html.erb” suffix (so you are writing html with Embeded Ruby). The file with prefix 0. is a main page. You can easy create the subchapters by adding more prefixes, like in the example below:
0. Introduction.html.erb 1. Chapter One.html.erb 1.1. Subchapter.html.erb
If you add the chapter, you must call +rake db:reload_chapters+ to initiate the chapter loading. Note it will only load new chapters - if you deleted or renamed some chapters, you need to run +rake db:remove_chapters+ before.
You should always use html paragraph - use the source code of this page as an example. To enable comments on the paragraph, add class “commentable” and assign the unique ID - this ID is used to find out to which character the comment belongs.
<p class='commentable' id='formatting'>
There is a number of helper function to easy compose the book. See the source code of this page to have an example.
bob_header(header) - generates the header (like “Helper Functions” above) with the anchor
bob_last_read - renders html with the link to last read chapter
bob_new_arrivals(number_of_chapters) - renders html with links to newest number_of_chapters chapters
bob_link_to(url) - just a link to url
bob_link_to_chapter(chapter, title) - link to the given chapter (could be a number, a name or :next or :first symbol); title is optional
bob_left_span - start division of the current paragraph to left and right span (like at the first paragraph of this page)
bob_right_span - the html below this will occur in the right span
bob_end_spans - mark the end of the paragraph division
Example use of bob_link_to_chapter
bob_link_to_chapter :next, "Next Chapter" # link to the next chapter bob_link_to_chapter [1,1] # link to the chapter 1.1. bob_link_to_chapter "Chapter One" # link to the chapter by name
Including Source Code
<%= bob_code brush: :ruby do %> puts "Hello, world" <% end %>
All the config is done in config/application.rb. You can change the title, default view and turn of showing chapter number.
config.book_title = "Blog-o-Book" config.default_view = :blog # or :book config.show_chapter_no = true
