FIXME
|
|
|
|
1) feed_mode_scan doesn't find feed for https://www.blender.org/
|
|
even though it should be according to the pathnames dictionary.
|
|
|
|
TODO
|
|
|
|
0) Improve function http to return sensible value (the list is not good enough)
|
|
|
|
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
|
|
|
|
4) Replace sqlite.remove_nonexistent_entries by sqlite.check_entry_exist
|
|
Same check, just reverse.
|
|
|
|
5) Support protocol Gopher
|
|
See project /michael-lazar/pygopherd
|
|
See project /gopherball/gb
|
|
|
|
6) Support ActivityPub @person@domain (see Tip Of The Day).
