hurr-durr 0.0.2

Streaming async interface to 4chan boards

# What is this?

A streaming async API to 4chan boards. You create a handler class, implement some callbacks and get informed when new posts and images arrive in threads. There’s a bundled FileHandler that saves content to the file system.

# How?

The bundled executable called hurr-durr is a scraper. You use it as

hurr-durr –directory /tmp/4chan –board b

There’s an optional -i flag to also download the images and a -v flag to see logging information. All this is also available via the -h flag.

As for the API part, the main entry point is hurr_durr.ChanWatcher. You have to implement a handler class and then do something along the lines of

from hurr_durr import FileHandler, ChanWatcher

watcher = ChanWatcher(FileHandler(‘/tmp/4chan/b’), ‘b’, images=True) watcher.start()

The only handler currently bundled is a FileHandler which saves content to disk. To implement your own handler, you need to create a class containing 4 methods:

• post(thread_id, new_post) – gets called when a new post is made in a thread

• pruned(thread_id) – gets called when a thread is pruned from 4chan

• img(thread_id, filename, data) – gets called with downloaded image data, only relevant if images are downloaded

• download_img(thread_id, filename) – gets called to check if a particular image should be downloaded, only relevant

  if images are downloaded

# Why?

Because I needed a 4chan scraper, everything else sucked, and I wanted to give Tornado a ride around the block.
