A place to post new communities all over Lemmy for discovery and promotion.

Rules

The rules for behavior are a straight carry over of Mastodon.World's rules. You can click the link but we've reposted them here in brief, as a guideline. We will continue to use the Mastodon.World rules as the master list. Over all, be nice to each other and remember this isn't a community built around debate. For the rules about formatting your posts, scroll down to number 2.

1. Follow the rules of Mastodon.world, which can be found here.

A. Provide an inclusive and supportive environment. This means if it isn't rulebreaking and we can't be supportive to them then we probably shouldn't engage.

B. No illegal content.

C. Use content warnings where appropriate. This means mark your submissions NSFW if need be.

D. No uncivil behavior. This includes, but is not limited to: Name Calling; Bullying; Trolling; Disruptive Commenting; or Personal Criticisms.

E. No Harrassment. As an example in relation to Transgender people this includes, deadnaming, misgendering, and promotion of conversion therapy. Similarly Misogyny, Misandry, and Racism are also banned here.

2. Include a community or instance title and description in your post title. - A following example of this would be New Communities - A place to post new communities or instances all over Lemmy for discovery and promotion.

3. Follow the formatting. - The formatting as included below is important for people getting universal links across Lemmy as easily as possible.

Formatting

Please include this following format in your post:

[link text](/c/community@instance.com)

This provides a link that should work across instances, but in some cases it won't

You should also include either:

!community@instance.com

or instance.com/c/community

FAQ:

Q: Why do I get a 404?

A: At least one user in an instance needs to search for a community before it gets fetched. Searching for the community will bring it into the instance and it will fetch a few of the most recent posts without comments. If a user is subscribed to a community, then all of the future posts and interactions are now in-sync.

Q: When I try to create a post, the circle just spins forever. Why is that?

A: This is a current known issue with large communities. Sometimes it does get posted, but just continues spinning, but sometimes it doesn't get posted and continues spinning. If it doesn't actually get posted, the best thing to do is try later. However, only some people seem to be having this problem at the moment.

Crust.piefed.social (the Piefed development instance)

Not all instances implement it yet, I guess it depends how often they pull from the dev branch

What we really need is a revival of the functionality of the bot at !trendingcommunities@feddit.nl that died. I still miss it so much :(

[–] Blaze@lemmy.zip 15 points 4 days ago (1 children)

There was a revival attempt at !trendingcommunities@lemmy.cafe , but it was short lived.

That probably shows a trend: those type of tools need to be built-in into the software, relying on Raspberry Pies, scripts and external tools to provide such features will likely lead to them being abandoned

[–] Coelacanth@feddit.nu 7 points 4 days ago

Oh I missed that somehow! I'll subscribe just in case, but I agree with you that the functionality should ideally be built in to the software.

[–] Deceptichum@quokk.au 6 points 4 days ago

We do.

!trendingcommunities@lemmy.cafe

But it's also running intermittently, and hasn't been updated in a week or so.

[–] SatyrSack@quokk.au 2 points 4 days ago (2 children)

Is there a Python wrapper for writing PieFed bots? Or does Pythörhead work of-the-box for PieFed?

[–] db0@lemmy.dbzer0.com 2 points 4 days ago (1 children)

I don't think piefed has the same API has lemmy, so no. It's been something I wanted to onboard (the piefed API) ,but I haven't fouind the time.

[–] SatyrSack@quokk.au 2 points 4 days ago (1 children)

I do see there is code to throw an error when it detects an instance is not Lemmy, so it definitely doesn't work out-of-the-box. But the APIs for each are supposedly similar to each other, so it fortunately should not take any major rewrite to support both in the same wrapper.

[–] db0@lemmy.dbzer0.com 1 points 4 days ago* (last edited 4 days ago) (3 children)

Do you have a link to the API doc? Nevemind, found it: https://freamon.github.io/piefed-api/

[–] wjs018@piefed.social 4 points 4 days ago (1 children)

Like Blaze mentioned, the api is a bit of a work in progress and we are revamping the swagger. The version of the api spec you have there (freamon's) is manually created and can have some inaccuracies because of that. We are in the process of making the piefed api self-documenting so that inputs/outputs are validated against the schema, but there are a lot of endpoints still to go in that effort.

Some of those revamped endpoints are going to be coming in the 1.2 release. For the self-documented endpoints that have been done so far, you can check the swagger on crust (the dev instance running right off the main branch).

To keep up with this effort as I am working through it, I have been making posts to !piefed_api@piefed.social.


On a personal note, I would kill for a pythorhead-but-for-piefed to exist. I pretty extensively use pythorhead in my lemmy communities now, so I am hopeful that we can get the api in a stable enough state to enable tools like this to exist in the near future.

[–] db0@lemmy.dbzer0.com 3 points 3 days ago

Yeah I would like to support it as well. I'll wait until the API stabilizes though to avoid more work

I'll just remove the 'freamon' one when the auto-generated one is up to date.

The manually-generated one had 5 missing routes, which I've since added.

The auto-generated one at crust has about 48 missing routes. It's the right approach, and I'll help out with it when I can, but - for now at least - it makes no sense to redirect people to it (either automatically or via a comment).


Some thoughts for @wjs018@piefed.social

/site/instance_chooser probably doesn't need to be a route. It's just the data format returned by /site/instance_chooser_search. As a route, it's returning the instance info for the site you're querying, so if you want to keep it as a route, it should probably be called /site/instance_info or something.

In the query for /site/instance_chooser_search, nsfw and newbie are both booleans. With the rest of the API, these are sent as 'true' or 'false', but they are 'yes' and 'no' for this route. The newbie query should probably be newbie_friendly In the response, monthsmonitored should probably be months_monitored

There's no way to exclude communities for the response to /topic/list and /feed/list: If you don't put 'include_communities' in the query, it's defaults to True, but if you put 'include_communities=false' in the query it ends up being True also (because the word 'include_communities' is in the data).

TIL that rimu added instance chooser endpoints. I'll take a look at those before 1.2 gets shipped. Same with the topic and feed endpoints. The easiest time to make changes to them is now before they get more widely used.

I have about 10 more endpoints (working through /user right now) I have finished transitioning in a dev branch right now, so we are making progress.

[–] Coelacanth@feddit.nu 1 points 4 days ago

No clue, sorry.

[–] nethad@discuss.tchncs.de 1 points 4 days ago (1 children)

didn't even realize it died :/ do you know why?

[–] Coelacanth@feddit.nu 1 points 4 days ago

No idea, it just stopped working. It already didn't work with Piefed communities I think, maybe it was taken down for maintenance and never put back up?

[–] crimeschneck@sopuli.xyz 5 points 3 days ago (2 children)

One important thing about Lemmyverse is that you can search for communities your instance isn't "aware of" yet. Seeing the "Add remote community" button, I guess this is something that's not possible with Piefed's community search?

[–] rimu@piefed.social 6 points 3 days ago* (last edited 3 days ago)

The other day I made a feature which automatically adds every community posted to newcommunities@lemmy.world. And another feature that automatically posts to that comm whenever a local community is created.

That's works on a ongoing basis. There are other features for bulk-adding communities as a one off job.

This post only says that the Lemmyverse data "is used to suggest search results to people when adding a remote community." Is this data also included in the communities page?

Another thought about the linked post: Removing inactive communities from the Lemmyverse data is certainly a good thing for stuff like "technology", "memes", "news" etc., but if you're looking for a community about a very niche topic you might even be interested in an inactive community without active alternatives to perhaps "revive" it with your posts.

[–] Blaze@lemmy.zip 4 points 3 days ago

I'll have to ping @rimu@piefed.social for your first question.

About your other paragraph, not sure what the inactive threshold is, but yeah, that could be useful.
