There's a proposal at the linked blog post for how to clean up the config directory.

The post goes into detail which changes would be required in KDE software using Qt.

After reading, I just have one question (the blog does not seem to have a comment section): how does this handle transitioning from the old location to the new location? Imagine having a katerc config file under ~/.config and one under ~/.config/kate (which is the suggestion from the post) - should those be merged once and then the old one gets deleted?

I answered something similar elsewhere:

If you mean migrating the files yourself, it's just a matter of copying the file from the old place ~/.config/yourconfigrc to ~/.config/yourapp/yourconfigrc.

If you mean you want the application to manage the migration itself, that's an implementation detail I hadn't thought about yet, but which I assume wouldn't be difficult to do with KConfig.

You can see this bit of code from Konsole showing how to migrate from old entries to new entries in the same config file for example: >https://invent.kde.org/utilities/konsole/-/blob/master/src/main.cpp#L99

The implementation could probably be something similar, with two KConfig/KSharedConfigPtr instances I assume πŸ‘€ so:

  • if oldConfig exists, create an object for it
  • read all oldConfig entries
  • if it differs from newConfig, store which ones differ
  • write all different oldConfig entries in newConfig object
  • sync()

Something like that.

Just for clarification: this would be a one-time process per application, right? I'm sure this will work for 99% of users, but there'll always be the one (or a couple of users) that synchronizes their .config directory, then doesn't update all machines at the same time and all hell breaks loose - a.k.a https://xkcd.com/1172/ :-) But I'd say that's probably not worth losing the advantages of a cleaner .config-directory, so this might be one of those "tough-luck" situations... 🀷

I think so. I mean, the migration code would still be there afterwards, maybe removed after several versions later.

If the user syncs machines with different application versions I'm not sure there's anything that can be done at the code level though. πŸ‘€

i agree with all of this, and in fact would go a step further to say: nicer names in general. what in the nine is plasma-org.kde.plasma.desktop-appletsrcβ€½ why not just plasma-appletsrc?

i think the real problem is the manpower to do it all though

@MartinR the Maven convention for packaging is a group identifer/package is the inverse domain order.

Taking plasma-org.kde.desktop-appletsrc you would create a group identifer of: org.plasma.kde.desktop With the artefact identifier being: appletsrc.

The folder structure would then look like:

.config  
\-\>org  
\-\>-\>plasma  
\-\>-\>-\>kde  
\-\>-\>-\>-\>desktop  
\-\>-\>-\>-\>-\>appletsrc  

Its simple

I always considered plasma to be a part/sub project of kde, therefore org.kde.plasma would seem correct-er.

The proposal isn't mine, I just read and shared it :-) The blog post has a paragraph or two about multpile subfolders, as I read it, the specification is not clear on whether thats supported? But actually: at first glance I think this would be better to have, because it would possibly make synchronizing to a new PC/Laptop even easier. However, this only works if any machine-specific settings (e.g. "offset /size of window") are not stored in config, as that might break if you sync config between a multi-monitor setup and a single-monitor setup. This requires a lot of thought...
