Mastodawn

Ω🪬Ω
new release of #Fedialgo, the customizable timeline algorithm / filtering system for your Mastodon feed, counts the number of times each hashtag appears in your timeline even if people don't use a "#" character to give you a better sense of what people are talking about in the Fediverse.

there's a little bit of art vs. science here because some strings are disqualified from this kind of counting (e.g. a word like "the" should not be counted even if some maniac decided to make it a hashtag) so let me know if you see any weirdly high counts.

@cryptadamist when trying to authenticate with gotosocial i get this error

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin hmm, is gotosocial fully interoperable with mastodon? i'm not 100% sure that it should even work...

also can you bring up the developer console and look at the error? (in firefox it's Tools->Browser Tools->Browser Console)

@marin thanks! it seems like it should be supported... i suspect you have run into a bug in the masto.js package; gonna poke around for a bit and will report the issue to the devs.

marin Jun 21, 2025

@cryptadamist hmm, but the app still _works_, but i tried to favourite a post and it actually worked, i opened the remote instance, looked at the favourites and i was there, but when i clicked the little open icon in fedialgo it led me to https://fedi.marin.fyi/@[email protected]/01JY96BSF84EFFW33GPENJ6X35 , which mastodon doesnt support, but i guess it works good enough even on gts

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin wait, so you only had an error when you tried to favourite a post or you hit the error when trying to login?

marin Jun 21, 2025

@cryptadamist when logging in, still on the left side of my screen it says this:

and just a bunch of those. but when i favourited a post nothing popped up and the icon turned orange-yellow-whatever and the post did actually get favourited

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin fascinating... OK those errors are discountable, it's just for whatever reason failing to pull the hashtag timeline for what it has identified as "trending" tags. maybe the GTS instance doesn't support the hashtag timeline function? (this function: https://docs.joinmastodon.org/methods/timelines/#tag)

that means you'll be relying on the search() API to find toots with trending tags but that's survivable.

but when did you get the error message you first posted, about the app failing to register itself? at login time or later?

@marin i think i managed to fix this issue; was a hangover from the code i forked that was doing some weird stuff. give it a try if you have a chance and let me know if it worked.

[edit] you might need to clear your cache / cookies for the app for the fix to apply

@marin are you running your own GoToSocial instance? if so maybe check how you've configured the registering of applications? This is the relevant section of the mastodon API:

https://docs.joinmastodon.org/methods/apps/

apps API methods - Mastodon documentation

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin also what version of gotosocial is your server running?

marin Jun 21, 2025

@cryptadamist latest(GoToSocial 0.19.1+git-6574dc8 )

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin thanks; added that information to the github issue

marin Jun 21, 2025

@cryptadamist http://marin.fyi/bug-fedialgo.mp4 u can add this as well, a full video of me doing all of it

marin Jun 21, 2025

@cryptadamist also shows the bug where it assumes my instance can handle remote posts, but thats not that big of a deal

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin cool, looking. is your GTS instance not able to resolve remote posts?

also curious: if you go in Experimental Features -> Show State there's a "homeserver" section... i'd be curious to see what's in there for a GTS instance, maybe there's some info there I can leverage to fix remote post link resolution.

@marin maybe click around in there and see if there's some kind of flag like "remotePostsEnabled" or something? tbh i have no idea if such a configuration parameter exists or what it might be called, but if we can find it i can handle this situation more elegantly by pointing links at the post's original server

marin Jun 21, 2025

@cryptadamist well you can always detect if its gts with the sourceUrl, and i doubt such thing will exist because im pretty sure gts just DOENST support it, not optional just doenst

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin so GTS instance sourceURL will always be "https://codeberg.org/superseriousbusiness/gotosocial" (or at least will always end with "gotosocial")?

if GTS never supports remote posts I think that's enough for me to fix the issue.

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin hopefully fixed/deployed in version 0.75.8 if you reload (version is in the header) but only for opening Toot links... not sure how it's going to work with submitting a reply because that's still going to try to resolve the URL to the local server because that's what a standard Mastodon instance requires. do you have any idea how to handle that?

specifically I guess the question is "what does one put in the 'inReplyToId' field when submitting a new Status object on a GoToSocial instance?" Mastodon requires that it be a local ID which usually is a number, though from your video it kind of looks like GoToSocial uses alphanumeric IDs?

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin also do you have any server side information about what happened with the favourite() call? in your video i just see "Internal Server Error" but seeing as how it succeeded it was probably not actually an internal server error and could possibly be some bad handling of the response by masto.js

[edit] and/or can you show me the client side browser logs from the attempt to favourite()? curious if there's any more information in there.

⚯ Michel de Cryptadamus ⚯Jun 21, 2025

@marin fwiw my hunch here after reassessing the evidence is that GoToSocial is resolving to a local alphanumeric ID that can probably be used to post a reply as it is... if you get a chance to test it out by posting a reply to a toot let me know how it goes.

⚯ Michel de Cryptadamus ⚯Jun 30, 2025

@marin my hunch was incorrect but i think i figured out the source of the problem:
