Autotagging

Tags can automatically be applied to entries discovered in specific feeds through extra syntax in ‘elfeed-feeds’. Normally this is a list of strings, but an item can also be a list, providing set of "autotags" for a feed’s entries.

(setq elfeed-feeds
      '(("https://nullprogram.com/feed/" blog emacs)
        "https://sachachua.com/blog/category/emacs-news/feed/" ;; no autotagging
