[irssi-feed.pl] don't repost same urls

[ralyodio]

would be nice if we had a local cache of feed posts so we don't repost the same link all the time if the feed hasn't been changed. Maybe even just take a hash of the feed content and compare it before running again.

In theory, the script already implements deduplication.

scripts.irssi.org/scripts/irssi-feed.pl

Line 435 in b6e5be9

push(@news, $item) if(not exists $itemids->{$item->id});

Loading up my old and unused-for-I-don't-known-how-many years irssi configuration, this still works. (Though it probably doesn't persist over irssi restarts.)

I think there's two possibilities

• The feed ralyodio is using doesn't have (stable) post ids
• The id extraction broke somehow because of a dependency update

@ralyodio Can you provide a link to a feed that doesn't work, and maybe check with http://blog.fefe.de/rss.xml whether that does work?

(In general, I don't think I can promise I'll fix this. I don't use irssi regularly anymore, and irssi-feed.pl is probably not a good idea in 2023, with its lack of https, and random short freezes. I suspect there's better bots for rss feeds these days.)
