[Feature Request]: Trigger colorchange by terminal command / bash script

[k1llerk3ks]

I have:

• Searched if this feature hasn't been requested yet.
• Verified that I am using the latest version (see Widget settings > About page or top right corner for version 1.1.0 and later), should be the same as https://github.com/luisbocanegra/plasma-panel-colorizer/releases/latest

Is your feature request related to a problem? Please describe.
I would love to change the color of the bar, depending on the activity i am on. basically i would love to trigger this by a bash command.

Describe the solution you'd like
some command i can run or file i can edit to change the custom color, without having to open the widget everytime
Describe alternatives you've considered
trying to create an extra bar for every activity, but that does not seem to work either

Additional context
thx for this amazing piece of software :)

So, i tinkered around a bit. I have a solution that kind of works, but is just a workaround that works mostly.

I created a preset and chose to load this preset on any of those change options.
Before switching the activity, i replace the color string in the presetfile. then i switch -
If i have a window maximized on that screen, the color changes, if not, then it doesn't change. is there some possibility to resync/update the color? I suppose, some bus command is sent out from the plugin.

Supporting preset auto-loading based on the current activity should be possible, an example of a widget that uses them is Activity Pager or Task Manager https://github.com/KDE/plasma-desktop/blob/master/applets/taskmanager/package/contents/ui/ContextMenu.qml.

I already use org.kde.taskmanager to detect maximized/active window so it should be a matter of listing and linking presets to them in the presets auto-loading tab, then implement the detection and switch similar to existing ones.

For future reference here's an example of what presetAutoloading (https://github.com/luisbocanegra/plasma-panel-colorizer/blob/0b3fa70a665a69c073e3e20cdc05000e14251507/package/contents/config/main.xml#L40C15-L40C32) currently stores:

{
    "enabled": true,
    "maximized": "/home/luis/.config/panel-colorizer/presets/border",
    "touchingWindow": "/home/luis/.config/panel-colorizer/presets/border",
    "floating": "/home/luis/.config/panel-colorizer/presets/border",
    "normal": "/home/luis/.config/panel-colorizer/presets/border",
    "maximizedFilterByActive": true
}

Maybe activities could be added like this:

{
    "enabled": true,
    "maximized": "/home/luis/.config/panel-colorizer/presets/border",
    "touchingWindow": "/home/luis/.config/panel-colorizer/presets/border",
    "floating": "/home/luis/.config/panel-colorizer/presets/border",
    "normal": "/home/luis/.config/panel-colorizer/presets/border",
    "maximizedFilterByActive": true,
    "activity": {
        "activity-identifier-1": "/home/luis/.config/panel-colorizer/presets/border",
        "activity-identifier-2": "/home/luis/.config/panel-colorizer/presets/border"
    }
}

This could be implemented by each widget exposing a D-Bus service using python, similar to what I did in https://github.com/luisbocanegra/plasma-cursor-eyes the difference would be that each panel need to be addressed in some way, possibly by creating separate service per panel unless there is a way to have a single service to talk to all the panels

Hi @k1llerk3ks, switching presets using the commandline with D-Bus has been added to dbus-service branch, can you check it out?

To update:

git clone https://github.com/luisbocanegra/plasma-panel-colorizer.git -b dbus-service
cd plasma-panel-colorizer
kpackagetool6 -t Plasma/Applet -u package

You may need to install the following packages if they aren't installed on your system

python-dbus python-gobject

After installing:

1. Go to the widget settings

2. In General tab enable the D-Bus service

3. To apply a preset can use qdbus6 and pass the absolute path of a preset:

   qdbus6 luisbocanegra.panel.colorizer.c337.w2346 /preset preset /path/to/preset/dir/

I thought about exposing individual configuration options (like color as you proposed) but decided not to as it would be too much work.
