yep, preventive action sounds like a good idea.

Check out also [2], which shows nicely what’s predefined in Qt5.

Yes, that also happens on the Qt5-based CI system and I already started
to mess with it, because the KDE devs on kde-framework-devel claimed
that Qt5 needs some patches in that area. However, as I’ve found a nice
piece of Qt5 documentation [2] yesterday, I haven’t gone back to that ML
yet, but it seems like that Qt5 already could be setting everything
appropriately.

I e.g. saw that the CI systems test files did go into the defined
~/.qttest directory.

Currently I have fiddled with it and now stuff like that goes into a
separate directory on my CI system [3].

That’s what’s also discussed on K-F-D [4] and I really wonder what’s the
better solution. I begin to think that René’s suggestion might be the
best way to handle things (as there are already many MacPorts-installed
applications based on GTK, KDE4 and Qt[45] which do save their files
XDG-compliantly):

I sort of don’t see the reason to go through the hassle of re-defining
everything just for the sake of Qt5, although David Faure isn’t in favour
of applying XDG standards to OSX...

But I guess this has be be discussed more widely than just among us!

As in said discussion with David [4] - honestly speaking - I get lost
over and over again, because there are so many different locations for
config and data files to be stored on a system (read-only and writable
ones). I lack knowledge about KF5’s inner workings (as well as Apple’s
rules regarding the placement of system and user data) and it would be
great if this whole area could be clarified a bit fruther. But I guess
Qt5/KF5 is currently only relevant to me currently, since you guys are
still busy enough with KDE 4 and still will be for quite a while to
come, I suppose...

Yet, I do need to patch Qt5’s sources for QStandardPaths in a certain way,
as I need to allow for the required redefinition of paths for use with
the CI system [5]. This was at lower priority for me up to now, since I
was rather busy building KF5 itself and some additional KF5-based apps
all along the route towards KMyMoney… But since Cristian Onet was so
amazingly active on the Windows port, we were now able to finally bring
the KMyMoney-KF5 port also for Linux to KDE’s Jenkins [6] and we have a
first successful build since yesterday! Hurray!!! :-D

So, this means, I can now focus on getting better CI-related patches into
Qt5’s sources… I am NOT looking forward to it, since it takes ages to
build and deploy the whole stuff… ;-(

Anyway, I think it would be good, if we could come to a consensus about
the (read-only, writeable) data/config locations on OSX! I don’t believe
you also want to join the K-F-D mailing list, but perhaps we can come up
with a decision here and I’d then go back with it to K-D-E.

If we only had even more (real) OSX devs on this ML!!! ;-)
But I am very happy about the two we do have! :-D
Great that René joined the team!!! I hope he and you, Ian, will serve as
some trigger to attract more KDE and OSX devs to support us here on KDE-MAC.

Greets,
Marko

P.S.: Am I writing too much, perhaps?
