A4A

A4A (Asyncio 4chan Archiver or Asyncio 4 Archiving, depending on how much the reader cares about the 4chan API ToS) is a Python script to download all images/videos of a 4chan thread.

Usage

A4A is a Python script to download all files from 4chan(nel) threads.

Usage: inb4404.py [OPTIONS] THREAD [THREAD]...
       inb4404.py [OPTIONS] -l LIST [-l LIST]...

Thread:
  4chan(nel) thread URL

Options:
  -h, --help          show help
  -l, --list LIST     read thread links from file
  -q, --quiet         suppress non-error output
  -p, --path PATH     set output directory (def: <script location>/downloads)
  -f, --filenames     use original filenames instead of UNIX timestamps
  -a, --archive FILE  keep track of downloaded files by logging MD5 hashes
  --connections N     number of connections to use (def: 10)
  --retries N         how often to retry a thread if errors occur (def: 5)
                        N<0 to retry indefinitely (not recommended)

Requirements

• Python >= 3.7
• aiohttp

Paths

The final output directory is assembled according to the following structure

<base path>/<board>/<directory name>

<base path> and <directory name> are variable components, which can be changed by the user.

• <base path> can be changed with -p/--path (defaults to <path to inb4404.py>/downloads)
• <directory name> can be set by adding the desired name to the thread link separated by another "/" (defaults to thread number)

For example:

https://boards.4channel.org/abc/thread/12345678        -> <path to inb4404.py>/downloads/abc/12345678
https://boards.4channel.org/abc/thread/12345678/my_dir -> <path to inb4404.py>/downloads/abc/my_dir

Lists

Input in the form of text files containing thread links is possible with the -l/--list option. Unlike Exceen's version A4A doesn't need list input to download multiple files at once. The option is simply there for convenience.

Each thread link should be on a new line. Lines starting with # will be ignored.
