They can indeed federate, but IMO it's not useful beyond simple posts.
There is no way to "sync" the text heading/URL/thumbnail.
@Skiluros What do you mean by sync exactly?
Where the fields in a Lemmy post (heading/URL/Thumbnail URL) are inputted correctly from a Mastodon post. URL is not even possible unless it's part of the body.
@Skiluros Heading URL is the 1st line of your mastodon post.
You can join an image to your mastodon comment and it will show on lemmy (a new post will just show the link to the post)
For URL and thumbnail I don't think you can.
IIRC, when the URL (on the Mastodon side) is the first line, it pushes a text URL as the heading in Lemmy.
Image attachments work too, if you're only using images.
The issue is you can't have a Lemmy URL, a text heading and a custom thumbnail image in a single post.
This creates problems if you have both a Lemmy community and a Mastodon account and you want post only from the Mastodon account (with the post also going to Lemmy).
I spent a lot of time experimenting with this and I couldn't find a good solution. I stick to posting to Lemmy and Mastodon using separate accounts.
This is a neat overview!! I like to federate my posts from microblogs as well, and did some tests.
Here are a few of my notes:
Viewing communities (from Mastodon) - that kind of depends? All communities I follow show up with their posts intact on mastodon (.social), but not when I use a different instance (e.g. mastodon.de) or software (examples: RenPy, Otome Games)
Viewing profiles (from Mastodon) - That also seems to depend on the instance. For example, here's my profile as seen from mastodon.social. Viewing it from my Mastodon account, I can see all of the original posts and replies.
@Berin
Here's how yours look for me.
Notice how it says 0 message on top, but can still see your posts?
Maybe you need to follow someone from the remote instance so they know each other and can federate. That's just a guess.
That could be the case! I do follow my lemmy-account from mastodon, (and the communities I mentioned as well).
Nice. Now try PieFed and MBin ๐ They should have some more compatibility beyond their own niche.
Would be great to have all posts on the frontpage of mastodon.social automatical federated to a community in feddit.org
(Like rss feed.) So I don't have to use two Apps/Browser-Tabs and have all Information in one App/Browser-Tab.
@MrFloppy I agree! I sometimes received notifications on Mastodon from comments by Lemmy accounts on this post but far from with all comments (~10%) and sometimes my replies on Mastodon didn't carry over to Lemmy (I don't even know if this one will!) so there's still work to be done to get things working just right!
I think this would be a great opportunity to get some of the work from Mastodon to feddit.org>comics_auf_deutsch But just when it's automated, that it's automatically send from Mastodon to feddit.
