Given a cantata number, spit out some useful links, and copy them to a paste-able format suitable for, e.g. quip.

linker.py

#!/usr/bin/env python3
import sys

def main(bwv):
    bwv0 = '%03d' % int(bwv)

    links = {
        # label: (url template, raw?)
        bwv: ('http://www.bach-cantatas.com/BWV{slug}.htm', True),
        'allofbach permalink': ('https://www.bachvereniging.nl/en/bwv/bwv-{slug}', True),
        'translation': ('https://www.emmanuelmusic.org/bach-translations/bwv-{slug}', False),
        'wikipedia':  ('https://en.wikipedia.org/w/index.php?title=BWV_{slug}', True),
        'note': ('https://www.emmanuelmusic.org/bach-notes/bwv-{slug}', False),
    }

    for (label, (link, raw)) in links.items():
        slug = bwv if raw else bwv0
        url = link.format(slug=slug)
        print(f" * [{label}]({url})")


if __name__ == '__main__':
    try:
        main(sys.argv[1])
    except IndexError:
        print("Please provide a cantata BWV number")
        print("suggested usage: ")
        print("./linker.py 31 | pbcopy")
