Summary

Currently, if one wants to install a scripted effect from the KDE Store,
the effect won't show up in the Desktop Effects KCM. The reason for that
is kpackagetool5 doesn't know where to install effects (they have to be
installed under ${DATA_DIR}/kwin/effects).

Another problem is that even if the scripted effect is installed in the
right directory (e.g. ~/.local/share/kwin/effects), it won't be listed in
the Desktop Effects KCM because it doesn't have a desktop file in
kservices5 dir. Please notice that the effect will be "visible" for KWin, i.e.
you can enable it by editing kwinrc.

This diff addresses those 2 problems by:

  • Adding a PackageStructure plugin for effects (so they are installed under kwin/effects/);
  • Using KPackage::PackageLoader to get list of scripted effect in the Desktop Effects KCM.
Test Plan
  • Installed an effect from the KDE Store, it appeared in the Desktop Effects KCM;
  • Removed it.

Fix typo in my last name

It's a bit weird to use kpackage here but not in ScriptedEffect itself but we can deal with that later.

I have a vague recollection of this previously being blocked on the grounds of "security" but I can't see it in my logs anywhere.

kcmkwin/kwincompositing/model.cpp
28–29

can we drop these?

The exact file path is hardcoded as config/main.qml, at which point we should add a fileDefintion for that instead

Where is effect defined?

ScriptedEffectLoader also uses KPackage.

Copy-paste.

I also wonder why other package structure plugins do the same. Can we drop it?
