Apparently just setting HOME does not work anymore. At least in my Plasma setup XDG_DATA_HOME and XDG_CONFIG_HOME are now interfering. This change introduced an extra helper script to take care of the environment variables which unsets the XDG_… variables and also takes care of QT_PLUGIN_PATH by the way.

# Testing and debugging Plasma 5 plasmoid with Qt Creator
|
|
|
|
The following instructions allow to test the Plasmoid by installing it in a test directory
|
|
rather than the regular home to separate testing from production.
|
|
|
|
1. Build as usual, ensure `NO_PLASMOID` is turned off
|
|
2. Add build step to execute the custom target `init_plasmoid_testing` which
|
|
will install the Plasmoid in a test directory which is `$CMAKE_BUILD_DIR/plasmoid-testing`
|
|
by default
|
|
3. Add new config for run in Qt Creator and set `bash` as executable
|
|
4. Set `%{sourceDir}/../../syncthingtray/plasmoid/scripts/starttesting.sh plasmoidviewer --applet martchus.syncthingplasmoid`
|
|
as CLI argument
|
|
* It is also possible to use `plasmawindowed` or `plasmashell`, see sections below.
|
|
* This usage of `%{sourceDir}` assumes one used the "Building this straight" instructions
|
|
from the main README.md.
|
|
5. Keep `%{buildDir}` as working directory.
|
|
6. In execution environment there's nothing mandatory to be set because `starttesting.sh` should
|
|
already take care of setting the environment.
|
|
* The home directory is set in accordance with the directory used in step 2. but can be overridden
|
|
by setting `TEST_HOME`
|
|
* If not already set, `QT_PLUGIN_PATH` is set to `$CMAKE_CURRENT_BINARY_DIR/plasmoid/lib` which
|
|
should contain the plugin for the Plasmoid under `plasma/applets/libsyncthingplasmoid.so`
|
|
* `QT_DEBUG_PLUGINS` to 1 for verbose plugin detection
|
|
7. Ignore warning that executable is no debug build, it is sufficiant when
|
|
the plugin is a debug build (see next section for QML debugging)
|
|
|
|
## Saving/restoring settings
|
|
|
|
Be aware that `plasmoidviewer` will revert Plasmoid-specific settings to the defaults on
|
|
startup. So it is not possible to test restoring/saving settings using it.
|
|
For this use case, `plasmawindowed` can be used instead.
|
|
|
|
## Testing within the real Plasma shell
|
|
|
|
Some issues are only reproducible within the actual Plasma shell. It is possible to test
|
|
with the real Plasma shell in the same way as described above by setting `plasmashell` as
|
|
executable.
|
|
|
|
It is only possible to run one `plasmashell` at a time so you have to stop your regular
|
|
`plasmashell` first. While developing you can start e.g. `tint2` to be not without a shell.
|
|
It works quite well within a Plasma session when both shells are placed on different screen
|
|
edges.
|
|
|
|
## Enable QML debugging
|
|
|
|
To enable QML debugging, it is required to rebuild `plasmoidviewer` with QML debugging
|
|
enabled.
|
|
|
|
For Arch Linux, I created the package
|
|
[`plasmoidviewer-debug`](https://github.com/Martchus/PKGBUILDs/tree/master/plasmoidviewer-debug/default)
|
|
for that purpose. Installing this package and using `plasmoidviewer-debug` instead of `plasmoidviewer`
|
|
should make enabling QML debugging in the *Run* section of Qt Creator work.
|
|
|
|
To create a debug build of `plasmoidviewer` manually:
|
|
|
|
1. Get plasma-sdk: `git clone https://anongit.kde.org/plasma-sdk.git`
|
|
2. Create a debug build of `plasmoidviewer` and ensure `QT_QML_DEBUG` is defined when
|
|
compiling `plasmoidviewer`, eg. by applying
|
|
[[PATCH] Enable QML debugging](https://raw.githubusercontent.com/Martchus/PKGBUILDs/master/plasmoidviewer-debug/default/0001-Enable-QML-debugging.patch).
|
|
3. Prepend the build directory containing the `plasmoidviewer` binary to the path variable
|
|
in the build environment of Syncthing Tray.
|
|
4. Enable QML debugging in the *Run* section.
