I think the title says it all. Basically, when a new comment appears on your targeted post, it sends you a PM about it.

@PostWatchBot@lemy.lol

Usage

  • Subscribe to a post: just mention the bot in the comments or send the link to the bot via PM.
  • Unsubscribe from a post: send PM to the bot with stop text and link of the post like stop https://lemmy.ml/post/1234
  • Unsubscribe completely: Send PM to the bot and add stop text to your message. It will unsubscribe you from all subscriptions.

Note: the bot sends only one notification per post. It waits for the previous notification to be marked as read for new comments.

Made with @CannotSleep420@hexbear.net’s lemmy-bot project 🙏 Tomorrow I will publish the code publicly after adding README and self-hosting guide.

    Its polling every 30th second only on my instance. So don’t worry, it will not make any difference for you ✌️

      in theory as you operate both the server and the bot you could modify lemmy to tell the bot when a new comment hits a thread instead of polling, which would be more efficient (but definitely harder to do!)

      also does it handle the case where nobody from your instance is following a community? to make sure you get all the replies reliably the bot would need to subscribe to each community it’s watching a post from

      that said, great work. I may end up using it if I don’t end up forgetting about its existence :p

        I’m using a library named lemmy-bot. To achieve what you say, I need to modify both library and lemmy server. As you can guess, I can’t afford time for these 🙂

        I think it’s not using much resources anyways. 2 requests per minute is nothing compared to hundreds of ActivityPub requests per second.

        I didn’t tested non-followed community, but the bot works with mention event instead of comment. But still not sure, I’ll test this one 🙏

          oh, I meant for the actual post watching part, summoning via mention should work without any subscription

            I think to get mentioned comment, it needs to get parent post too. As I said, I need to test it. I can only assume right now.
