To read random post, head to gfgreader.info.
- All articles now have titles. So table of content shows all articles.
- Encoding problem has been fixed.
- A book of Amazon interview questions under
goodies/interview_questions - Several pdf books have been generated.
Look under subdirectory goodies. Each book under geeksforgeeks is generated with articles under a tag/category on geeksforgeeks.org. The book under leetcode is generated from the articles on leetcode.com.
Here's how the books look like in the iBooks App and Kindle App on my iPad. Kindle hasn't been tested.
Want to create a book from the geeksforgeeks site yourself? No problem. But you'll need some tools to get started. Apart from Python 2.x you also need the following tools.
Scrapy is used to download webpages from geeksforgeeks and leetcode. It makes it super easy to do so with its rules.
Install it with pip install scrapy
So you have the html files locally. But those html files have many other stuff you don't want. You only want... goodies. No problem. Check out boilerpipy, it can remove all the unnecessary stuff like header and comments, leaving you with only the article itself. It has the functionality of Pocket or Readability you might be familiar with.
However, I've found that it also removes the title of an article sometimes. So I had to do some post-processing with lxml after to add the title back.
Pandoc is used to convert html files or markdown files to epub, pdf and docx files. The latex engine used in Pandoc can't handle gif images so only a few pdf books have been generated so far.
You'll need kindlegen to generate mobi files so you can read on your beloved Kindle or Kindle App. Download it from the linked Amazon webpage and install.
You just need to use kindlegen awesome.epub and it'll give you a file called awesome.mobi.
Go to the geeksforgeeks subdirectory and run commands like scrapy crawl geeksforgeeks -a category=category -a name=name.
For example, running scrapy crawl geeksforgeeks -a category=tag -a name=pattern-searching will crawl from the page http://www.geeksforgeeks.org/tag/pattern-searching/. category and name are two arguments our spider takes. On geeksforgeeks, things can be organized by tag or category. Specify the category/tag and the name, Scrapy will do the rest for you.
Following the example in 1, now go into the geeksforgeeks-books subdirectory and you should be able to find a directory called pattern-searching. Now run python generate_book.py pattern-searching. It will first clean the html files, concatenate the cleaned files into one, then use pandoc to create an epub file from the markdown file. In the end a mobi file is created using kindlegen.
Yay! Done!
Style the books better. Those books are essentially styled via css. Therefore styling <pre> and code tag, for instance, will style the code of the epub books.
I've only worked on this project for a few days since I had the idea. It has huge room to improve. It's the first time I used Scrapy and pandoc.
You can contribute in many ways. Besides contributing code to this project. You are more than welcome to contribute in the following ways.
Every tag or category on geeksforgeeks.org can be turned into a book. So you are welcome to add/suggest more books.
The style for generating epub books is under styles subdirectory. epub books are styled via css. Welcome to submit your stylesheets.
The content in the books doesn't belong to me. I created the books so other people and me can read them offline on iPad or Kindle, and (hopefully) for a better reading experience.
