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.

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.

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.
