4chan

Simple 4chan is a gem that fetches posts from 4chan. A complete reading solution to fetch posts from 4chan into your ruby, any rack-based or rails app. You set the board and simple-fourchan will fetch all posts from a board or thread number.

BUGS:

Some boards are not available from 4chan. I've contacted them to see what's happening. If you reach a board where simple-fourchan cannot fetch, you will receive an error message.

Updates

SEP - 08 - 2012: Update with board reading based from dongfix update.

Installation

Just do in your Gemfile or install and do require 'simple-fourchan'.

gem 'simple-fourchan'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple-fourchan

Usage

Fetching all threads from a board.

require 'simple-fourchan'

board = Fourchan::Board.new "w"

board.threads

It will return an array with hashes containing basic info from each thread.

For now, you can fetch a reply list from a thread number.

array = Fourchan::Post.new "w", "1403853"

Example:

If the gem is loaded:

array = Fourchan::Post.new "w", "1403853"

It returns an array of 4chan posts.

You should start like this:

Fourchan::Post.new "BOARD_LETTER", "THREAD_NUMBER"

array = Fourchan::Post.new "w", "1403853"
posts = array.all

Useful methods:

Some methods may be missed depending what user submitted: title, image, thumb, etc....

posts.each do |post|
  post.title            # =>   "One of the best anime's in my opinion!"
  post.now           # =>    "09\/06\/12(Thu)14:20"
  post.name         # =>    "Anonymous"
  post.email         # =>     "[email protected]"
  post.com           # =>     "One of the best anime's in my opinion!"
  post.image        # =>     "http://images.4chan.org/w/src/1346955606165.jpg"
  post.thumb        # =>     "http://thumbs.4chan.org/w/thumb/1346955606165s.jpg"
  post.link            # =>     "http://boards.4chan.org/w/res/1403853"
end

You can also do this in a more through way:
