    TEMP Add some Readme-files for packaging Plasma for Guix.
    
    This is just to pass my knowledge and processing to somebody who wants to
    work in Plasma for Guix.

+This branch contains my work for bringing the KDE Plasma dekstop to Guix.
+
+Hartmut Goebel, Juni 2019 & January 2021
+
+Note 1: It might be worth making an older version of Plasma work, as this an
+        older version has less dependencies. This is why this branch still
+        sticks at 5.19.5.
+
+Note 2: https://invent.kde.org/plasma lists about 60 packages, many of which
+       are applications.  I expect most of these
+       applications to be not required to start the Plasma Desktop.
+       See 10-TODO-plasma.txt for more information.
+
+
+About the other Readme-files
+===============================
+
+* 10-TODO-….txt contain the status of my efforts (which might be outdated) and
+  a lot of snippets useful for building packages and making tests pass.
+
+  Please at least skim through these files as they contain lots hof hints and
+  some gems :-)
+
+  The most central of this is the "Status Unit-tests" in
+  10-TODO-plasma.txt. This documents the status of building the packages
+  required for plasma. I'm encouraging you to use this list to avoid getting
+  lost :-)
+
+
+Proposed approach
+==========================
+
+  1. Make the packages listed in "Status Unit-tests" in
+     10-TODO-plasma.txt. build and (most) tests pass. This list hopefully
+     contains all package required for a minimal Plasma desktop service.
+
+     I suggest using the plasma versions currently package on this branch to
+     avoid introducing more issues.
+
+  2. Build a system (see gnu/system/examples/plasma.tmpl and
+     gnu/services/desktop.scm) which starts runs a small (or even minimal)
+     Plasma desktop.
+
+  3. Define two (maybe more) desktop-services:
+     - plasma-minimal
+     - plasma
+     (- plasma-all-bells-and-wistels)
+
+
+Notes about my Commit messages
+====================================
+
+  I'm using pre- and postfixes in my commit messages:
+
+  - TEMP: This is an intermediate commit to preserve some state. This might be
+    dropped, merged, fixed, etc. later.
+  - REWORD: Message needs rewording (e.g. is not written well or unfinished)
+  - FIXUP: This is a fixup for another commit, which should be `fixup`d using
+    `git rebase -i` soon.
+  - SQUASH: same, but to be `sqash`ed.
+  - WIP: work in progress, commited to preserve acceptable state
+  - TODO: This is unfinished work

+=====================
+KDE Plasma
+=====================
+
+When Plasma is running on Guix System, enlist Guix System at
+https://community.kde.org/Plasma/Packages
+
+
+https://invent.kde.org/plasma lists about 60 packages, many of which
+are applications.  I expect most of these
+applications to be not required to start the Plasma Desktop.
+I expect plasma-desktop, plasma-workspace, kwin, kwayland-server,
+plasma-wayland-protocols, kwayland-integration, and ksysguard
+to be sufficient to start the Plasma Desktop.
+This is why the commits adding these are "grouped".
+
+
+Status as of January 2021:
+
+* plasma-desktop builds, most tests are passing.
+
+* Directory 99-playground/ contains file to test the desktop following the
+  idea from
+  <https://guix.gnu.org/de/blog/2019/running-a-guix-xfce-desktop-on-centos-7/>.
+
+  The basic idea: Start an X11 server (provided by the host OS) on another
+  virtual terminal and make this run the desktop. See there for a short Readme.
+
+* when trying to start the desktop following the idea from

+Patch startkde (and startplasma?:

+Desktop-Service
+----------------------
+
+Not sure what this notes are for, I assume this is a list of rin-time packages
+required to run plasma (kinit)
+
+xrdb
+xprop

+
+Snippets for Commit messages or comments
+========================================
+
+Use this template to provide document what you tried to make tests pass, but
+did not suffice.
+
+Setting QT_PLUGIN_PATH,
+starting a X11-server, openbox and kdeinit5
+or running ctest via dbus-launch
+are not sufficient to make the
+two failing test-cases pass.

+- starts `Xvfb :90 -ac -screen 0 1600x1200x24+32`
+- starts `openbox`
+- runs `dbus-launch` and sets all the environement variables
+- runs `update-mime-database …/share/mime`
+- runs `kdeinit5` in the background
+- runs `ctest -T Test --output-on-failure … --timeout {timeLimit}

+Find dependencies
+==================================================
+
+Several places where to find required packages:
+
+https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/x11/desktop-managers/plasma5.nix
+
+https://github.com/NixOS/nixpkgs/tree/master/pkgs/desktops/plasma-5
+
+https://apps.fedoraproject.org/packages/
+
+https://cgit.kde.org/sysadmin/ci-tooling.git/tree/system-images/suse-qt511/Dockerfile
+
+
+Check if the tests for a packages actually passes at KDE
+============================================================
+
+For some package versions text fail even at KDE jenkins. THus it is worth
+spending checking prior to spending time on fixing:
+
+https://build.kde.org/   # jenkins
+-> search project
+-> go to last passing build
+-> "show unformated"

+Run Plasma in a Test-System (QEMU)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Hint: I had had some helper scripts to run within the VM to simplify testing,
+but these got lsot somewhen.

+# build the VM
+./pre-inst-env guix system vm-image --image-size=7G  --fallback \
+    --share=$PWD=/exchange \

+# things within the system without rebuilding the system-image, e.g.
+# build packages)

+Find desktop-file defining a property
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+find /gnu/store/* -name \*.desktop 2>/dev/null | \
+   xargs grep -rl PropertyDef::X-KDE-DBus-ModuleName
+
+
+Build packages within the VM
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+# log into the VM (port 10022 is forwarded to port 22, see above)
+ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 10022 \
+    root@localhost
+# make your development environment available within the VM (this needs to
+# keep the same absolute path to avois re-configure
+
+mkdir -p /exchange /path/of/your/develop/env/on/the/host
+mount -t 9p TAG_PWD /exchange
+mount -t none -o bind /exchange /path/of/your/develop/env/on/the/host

+Unknon snippet (maybe for qscintilla)
