Bluarchive, A Bluprint Downloader

Bluprint, formerly Craftsy, has announced that they are closing, without yet announcing a method of downloading purchased content. This project is intended to allow customers to preserve their purchases.

Features

Saves patterns, class materials, and class videos, including muxed subtitles and chapters. Also preserves original vtt subtitles, since they can't go into mp4, and metadata for patterns and classes.

Abridged output example:

Patterns/patterns.json
Patterns/Funktional Threads Christmas Stocking/stocking_aiid894970.pdf
Making Leather Bags (272)/playlist.json
Making Leather Bags (272)/1. Meet Don Morin & Plan Your Bag.mp4
Making Leather Bags (272)/1. Meet Don Morin & Plan Your Bag.vtt
Making Leather Bags (272)/materials/making-leather-bags-instructions.pdf
