hurr-durr 0.2.2

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 and a
`SQLiteHandler` that saves posts in per-date SQLite DBs.

**NOTE**: the `FileHandler` will eat up your `inode`s, a default Debian install scraping */b/* got exhausted in ~ 6
months. Use the `SQLiteHandler` unless you plan to clean the file root regularly.

# How?

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

hurr-durr --directory /tmp/4chan/sqlite-files --board b

There's an optional `-i` flag to also download the images and a `-v` flag to see logging information.

Storage defaults to SQLite DB per day, unless overridden via `-f file`, which produces 1 JSON file per thread in a
structure of `data_dir/YYYYmmdd/threadID/threadID.json`.

All this info 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

```python
from hurr_durr import FileHandler, ChanWatcher

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

or

```python
from hurr_durr import SQLiteHandler, ChanWatcher

watcher = ChanWatcher(SQLiteHandler('/tmp/4chan/b'), 'b')
watcher.start()
```

The handlers currently bundled are `FileHandler` which saves content to disk in files and `SQLiteHandler`, which saves
posts in SQLite DBs. To implement your own handler, you need to create a class inheriting from `Handler`,
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

# Installing

It's in PyPI, just use pip

pip install hurr-durr

# Why?

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