That gentoo page is fairly optimistic in that it's considering wayland
support "complete" just because it works for common use cases.

applications as Wayland clients. The server side is the QtCompositor API,
and allows users to write their own Wayland compositors."

This is definitely incorrect. Qt5 on wayland, regardless of whether or not
QtWayland is in play, will still be broken. It will "kind of" work in some
circumstances, but eg docks/toolbars are broken and will NEVER work
correctly under this setup.

"becoming more reliable" does not equate to "reliable" 藍

Right, but that's all focusing on a very narrow topic -- getting client
side decorations working under wayland and allowing Qt applications to
open. Once again, trying to use anything but a very simple single window /
"hello world" type application will quickly run into breakage. That
particular page is written from a "running Qt apps on Wayland under gnome"
viewpoint, and isn't trying to consider the lower lying topics about
getting full functionality for any qt app (on any platform) working under
Wayland.

I should have linked to the original posting relating to this (couldn't
find it yesterday). Here's the full gory details:

There is quite extensive support for working with QGIS projects via
Python.  You could write a Python script and run it from the CLI.

[Qgis-user] Is there any CLI to create and manage a QGIS project

2024-01-18 Thread andy via QGIS-User 
Hello,
I would like to create a project and then, for example, given a list of
files, put all those whose names begin with "OC" in the ocean group, and
all others in the root of the project, and finally sort them
programmatically, according to values I have in a list of my own.

I know it is an XML file and I can use an XML cli utility.

Here I am asking if there is anything already dedicated to QGIS project.

Thank you
