Solved : No, you can't

Can I crosspost on Piefed? [Solved : No, you can't]

I'm discovering the threadiverse through a new account and software.
I wanted to crosspost a Lemmy post into another Lemmy community. Can I do this from a Piefed instance?

EDIT : No, you can't. You can only reference another post using a link.

Here is an example of a crosspost btw two Lemmy instances. Piefed only allow to access the link btw them

Here is an example of copy-pasting a link to a Lemmy post into a new Piefed post. There is only the link but no proper crosspost

Note that I attached in my test the post to the software of the poster not of the community.

Right now Piefed voluntarily allow crosspost for bot only as stated by @Rimu here
https://codeberg.org/rimu/pyfedi/issues/206

I've added a feature for a limited form of cross-posting - on any bot-created post, if it hasn't been posted elsewhere yet, there is a cross-posting button. This is most obvious at https://piefed.social/c/[email protected] where a large percentage of the links have already been posted in 'real' communities.

Long-term we will want to have cross-posting on all post types but I don't really want to encourage cross-posting until we handle duplicate posts better, like Mbin does.

Thank you all for helping me figure this out

2nd EDIT: We figure out in the comments a way to get the crosspost pick up by Lemmy but it is only for post having an external reference and it is not picked up by Piefed.

  • Cross-posts are not fully implemented on Piefed: https://codeberg.org/rimu/pyfedi/issues/206

  • A cross-post is just a post that links to the same URL as another post. The codeberg Issue that Blaze linked to mentions an exception, but other than that, there's not a convenient button that copy-pastes a post's title, body, and URL into a new 'Create Post' form. You can do it manually though, and everything that receives it will detect it as a cross-post, because everything is just looking for matching URLs.

    • A cross-post is just a post that links to the same URL as another post.

      I have to disagree with you. When I crosspost properly, I got the list of each community in which the post is found. I can also open the post in each community in my instance with a simple click.

      I vaguely remember reading that PieFed promised that cross-posts will have a single comment space but it seems we are not there yet. I tried what you told me but I could get crosspost. I just have posts referencing one another with a hyperlink.

  • The post you mentioned ('melting is tough') isn't picked up as a cross-post on PieFed instances because the dates are too far apart. A restriction that Rimu wanted was that they should only be detected if they were within 7 days of one another.

    However, if you take that URL (https://lemmy.world/pictrs/image/91f96cc8-a194-4cb8-abc6-505261e65420.jpeg), and make a new post with it, then the post you mentioned now shows that it has a cross-post.

    • Interesting. Let me try again with posts with closer dates.
      Do I need to use the URL of the picture or of the post itself to crosspost it successfully on Piefed?

      • The picture (or whatever external resource a post is pointing to, like https://bbc.com/news/article.html)

    • Here is a 4-days old post that I just crosspost from and to Lemmy
      https://feddit.online/post/165936
      It is not pickup as crosspost either.

      • Then I tried to crosspost it from Lemmy to Piefed using the link of the image and got an error. But many parameter could be the cause. I'll try again.

      • It's doesn't seem like feddit.online is aware of the other community ([email protected]), so it doesn't have a copy of both posts, so it doesn't know that they are cross-posts.

        If you bring that community into feddit.online, then create a post with the same URL as a recent post (e.g. https://files.catbox.moe/pebvir.jpeg), then they'll show up.

    • Here is another 4-days old post, this time with an external ressource crossposted from Lemmy to Piefed.
      It gets picked up as crosspost by Lemmy but unfortunatly not by Piefed
      https://feddit.online/post/165962

      Watching it from Piefed, I have no way to see that it match a post in another community as it doesn't even refer to the original post using hyperlink.

  • I would say you can
