Hi all,

This is a continuation of this thread around Mastodon/Lemmy integration.

I am trying to understand the formatting rules around Mastodon to Mastodon/Lemmy posts. My Mastodon instance is www.mstdn.games.

I was able to get this point:

Mastodon input:

Lemmy crosspost:

Let me walk through the key points.

1. Thumbnail

This works really well. You attach an image on Mastodon and it outputs the correct thumbnail on Lemmy (it even works across instances, I know there are issues with LW vs other instances in custom thumbnail attach).

2. Markdown Formatting

Doesn’t seem to work on the Mastodon side. Not a big deal, the only somewhat relevant piece is the markdown URL syntax, but I can just use [Text - URL] style formatting.

I read that Mastodon is supposed to support markdown, but it seems to not be the case. Doesn’t matter, but if someone has anyone info on this, I would appreciate it.

3. Mastodon to multiple Lemmy communities

I tried adding both !testfediverse@jlai.lu and !test@lemmy.ca. It seems only the first Lemmy community URL gets crossposted (I was able to post to !test@lemmy.ca when it was the first Lemmy URL).

Again, this is manageable. I can crosspost (within Lemmy) from my Lemmy account.

4. Direct URL Lemmy link with Text Heading

This doesn’t seem to work. This is really annoying.

I can get text heading working on the Lemmy side, but the Lemmy URL always points to the Mastodon post URL:

Is there a way to define the URL on the Mastodon side so that Lemmy understands that the post must point to a specific URL (while having a separate Lemmy text heading and not having the post look like shit on the Mastodon side).

The last piece is critical for me. I don’t want to post links to Mastodon in the !tycoon@lemmy.world community.

    Posting to multiple Lemmy communities is not a big deal (you can always crosspost with a Lemmy account).

    Links are taken from Activitypub attachment, but Mastodon only seems to support image attachments. So it is not possible to add other types of links unless Mastodon adds an option for that.

    This IMO kills the whole Lemmy <> Mastodon integration outside of some very, very simple use cases. The ability to have differentiation between a heading and a URL is critical.

    It’s too bad Mastodon doesn’t seem to support the URL function of Activitypub.

    Mastodon is by far the biggest fedi micro-blogging platform. I recognize the irony of what I am saying considering I want people to move from Reddit to Lemmy, but for niche topics like tycoon/business sim video games, my point stands.
