-This extension enables extra parsing for some special metadata keys. These are:
-
-- `tags`. Comma separated list of tags.
-- `emoji`. Emoji or emoji shortcode, checked that it's an actual emoji.
-- `author`. Name, URL or [both](#Name-with-URL) with the format `name <URL>`.
-- `source`. Same as `author`.
-- `time`. Time string with unit support. Like `2 hour 30 min`. This overrides past `prep_time`/`cook_time`.
