Also, another category:

KSudoku Games

(KSudoku code for KNS has been disabled for a while, but let's start the basic steps for reenabling it).

Gently ping @starbuck

All Categories have bveen added: https://store.kde.org/browse/cat/355/ord/latest/

Thanks! Did you see also my question about the possibility of sending contents from someone who is not the author?

Since knewstuff is now retired (and from my understanding didnt feature an account management?) the best would be

1. ask the authors to create an account and re-publish them.

KDE could of course set up a normal account at any time and handle all the items under that.
So that's up to whoever wants to decide that and take care of the account (its not possible to form some sort of group-login with multiple account members).

Thank you. Another question: is it possible that the name shown does not match the internal name? I see messages from knewstuff saying that the categories do not exists.

I tried few other categories, and for some programs the name shown is different from the internal name (for example, "KPat Themes" is really "KDE KPat Theme").

Yeah, that could be.
KNS/GHNS unfortunately has the habit to look for a hardcoded category name, so to make it work backwards compatible, I would need to know the exact string each program tries to match and add it as "legacy name" internally.

Ok, but then, what happened with the new categories? Just to name one, I fixed kdiamond according the name which is shown, but I see an error about non-existing category:

https://commits.kde.org/kdiamond/3ffd35d9babae34d189446d9ba2a2a799412c080

I see the same behavior with all the new categories created.

Isn't it https://autoconfig.kde.org/ocs/providers.xml nowadays (not sure about what is the prefered URL)?
Also, where do you get the error with what request?

I checked and see the categories listed live here:
https://api.kde-look.org/ocs/v1/content/categories

Thanks for the API reference to the list of the categories.

So, I'm puzzled: what I was seeing 24 hours ago where messages like:

kblocks(17615)/(org.kde.knewstuff.core) KNSCore::AtticaProvider::listOfCategoriesLoaded: Could not find category "KBlocks Themes"

ksnakeduel(20819)/(org.kde.knewstuff.core) KNSCore::AtticaProvider::listOfCategoriesLoaded: Could not find category "KSnakeDuel Themes"

The same code does not show the errors anymore. Some cache that had to be re-kicked on your side? I don't know, it seems to work, now I need to hunt down the previous authors to reupload the contents.

Anyway, thanks! I think that this can be closed; in the (hopefully unlikely) case that there are some issues, I can still comment.

Your welcome! If there are any more issues, just open a new ticket or re-open this one.
