beet configuration file

The beet crash when the lyrics plugin is enabled in the configuration file:

It will work if dev-python/beautifulsoup4 is installed. So it looks like there might be a missing dependency when media-sound/beets is installed

Arsen, you able to poke?
Comment 2 Arsen Arsenović gentoo-dev 2021-11-24 11:46:59 UTC
That's correct, it requires beautifulsoup4 for this plugin. What should be done about such optional dependencies?
Comment 3 Arsen Arsenović gentoo-dev 2021-11-24 17:33:50 UTC
Spoke to Sam on IRC. Here's a summary of our conversation (and action I'll be taking in the near future):

- use optfeature.eclass in this ebuild to specify which packages are necessary for what plugin
- extend optfeature.eclass to use readme.gentoo-r1.eclass to also put down the optional features in a permanent file rather than just elog
- update upstream to tell users to check their distribution-specific docs

This, however, does seem like a bug. The sources look like they should be telling you to install BS4, but fail because not all sources are consistently defined. I'll also report upstream.

Thank you for shining a light on this issue :D

BTW, just noting this down, this was fixed in master already:
