Script doesnt load

[Akselmo]

Hi, been looking for a script like this for a long while so I'm glad to see one

Unfortunately I can't get mine to work. I have it loaded in my Kwin Scripts settings, but the config button won't appear even after following the readme.

Here's what I get after running kwin_x11 --replace &

Icon theme "elementary" not found.

The problem should be fixed now; please reinstall, including running the fix described in the readme again, and see if it works now.

The settings menu now appeared, but the script is still not doing anything when i move the window around screen. Is there some way I can help you debug this?

[nclarius]

1. Did you make sure to reenable the script?
2. The script will only take action on windows that are approximately tiled to a screen quarter or half. Does the window you tried have the size of a half or quarter of the screen and is touching the screen edges?

[Akselmo]

1. Yup, i unchecked the script box, applied, checked the box and applied again
2. Yes, I moved the windows to the edge of the screen and got the "shadow box" that shows where the window will be applied when i release the mouse button. I also tried moving the windows around with shortcuts. I have dual monitors so i tried disabling one monitor as well to see if it was affecting this, but no dice.

I tried to run the script with qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.showInteractiveConsole and it returns

SyntaxError: Parse error

[Akselmo]

I enabled debug mode from kdebugsettings and kwin_x11 --replace & gave me this

kwin_scripting: defaultscript encountered an error at [Line  25 ]
kwin_scripting: Message:  "SyntaxError: Parse error"
kwin_scripting: -----------------
kwin_scripting:   "message" :  "Parse error"

kwin_scripting:   "fileName" :  ""

This also pops up when enabling the script from menu. Wonder what's going wrong with that part of code, since it works for you.

[Akselmo]

I figured it out! I had to change the

// add to watchlist when client is initially present or added
for (const client of workspace.clientList()) {
    onAdded(client);
}
workspace.clientAdded.connect(onAdded);

to other kind of for loop

// add to watchlist when client is initially present or added
const clients = workspace.clientList();
for (var i = 0; i < clients.length; i++) {
    onAdded(clients[i]);
}
workspace.clientAdded.connect(onAdded);

My guess is that I'm on older version of Kwin that doesnt support the kind of iteration for for loops you used. Now it works just fine for me!

[nclarius]

That sounds plausible, kudos for figuring that one out. I'm glad to hear it works now.
Which KWin version are you using (kwin_x11 --version)? Depending on how old it is, I might consider rewriting the script for broader compatibility.

[Akselmo]

kwin_x11 --version
kwin 5.21.4

Okay, thank you!
