bin/get-fandom-wiki-urls

#!/usr/bin/env python3
#
# This little script makes it easy to Archive All The Things.
# It prints a list of URLs from fandom wiki pages to stdout.
#
# Stdout can then be redirected to a plaintext file with e.g:
# `get-fandom-wiki-urls cyberpunk > ~/downloads/cyberpunk-wiki-urls.txt`
#
# These URLs can then be imported directly into ArchiveBox. Each URL will
# be a page of the local sitemap. The local sitemap is a list of wiki pages
# in alphabetical order. Importing the URLs scraped by the script into
# ArchiveBox with a depth of '1' will pull every URL one hop away, so every
# wiki page listed in the local sitemap will be archived.
#
# This script wouldn't be necessary if there was a way to view the entire
# local sitemap in one html page. Then all you'd have to do is import the
# URL for the local sitemap into ArchiveBox with a depth of '1'. As far I
# know there is no way to get this view of the local sitemap. For some
# unknown reason the Wiki fandom site developers didn't design the frontend
# to enable that.
