FIXME
1) feed_mode_scan doesn't find feed for https://www.blender.org/
even though it should be according to the pathnames dictionary.
2023-11-23 17:55:36 +01:00
TODO
1) Support Gemini and Gopher.
2) Check also for HTML, not only feed.bozo.
3) Add "if utility.is_feed(url, feed)" to view_entry and view_feed
2024-01-14 19:05:12 +01:00
4) Replace sqlite.remove_nonexistent_entries by sqlite.check_entry_exist
Same check, just reverse.
