how do I get wal-telegram to use the current wallpaper for me in KDE Plasma

[kun-codes]

The current wallpaper location can be found in ~/.config/plasma-org.kde.plasma.desktop-appletsrc afaik

[guillaumeboehm]

Is plasma-org.kde.plasma.desktop-appletsrc the image ? Or the directory of the image ? The telegram theme expects a jpg or png extension I believe so it wouldn't work with different names.

[kun-codes]

It is a file which has the current wallpaper location. I don't know how to tell wal-telegram the location of the current wallpaper.

[guillaumeboehm]

A file containing the location ? Not a symlink ? If it's a text file with the location you'd have to make a little script to first get the path in a variable and then call wal-telegram -b "$VARIABLE".

[kun-codes]

The problem is, I don't know how to get the path from the file, can you point me to a resource by which I can learn it myself first? Any Linux command line tools?

[guillaumeboehm]

It would probably depend on the format of the file. I would probably end up using the awk command or maybe grep ? You can always send me the content of the file I can maybe help you with it.

[kun-codes]

alright, I will try sending you the file by today

[kun-codes]

here it the file

the last line it shows the current selected wallpaper plugin in kde afaik

and in

Image=file:///home/<my-username>/.local/share/wallpapers/wp9434242.png
SlidePaths=/home/<my-username>local/share/wallpapers,/usr/share/wallpapers

it shows the image file path

Sorry in case it is too confusing to follow

[guillaumeboehm]

Hum ok, so before anything just know I'm in no way a scripting veteran so I might tell you some really dumb scripting habits and stuff xD But what I'd probably do is (if there is really no other place to know what your current wallpaper is) grep with a regex like grep -Pzo '(?<=\[Containments\]\[57\]\[Wallpaper\]\[org\.kde\.image\]\[General\]\nImage=)([^\n]*)' <your_file>, if the number 57 never changes, or eventually change the 57 for \d+ to match any number and extend the regex to include file://home/ which seems to select only the line you'd want.

You can do your research but to guide you a bit, grep returns the matches found in a file on a given pattern. The -P option uses perl regexp which is more powerfull, -z basically allows you to do multiline matching, and -o prints only what's matched by the regex. If you're not familiar with regex you can mess around on regex101.com which is a must use to test your regex and all.

So what you can do is either use a long command with wal-telegram -b $(<grep comand>) or make a little script that you'd call on system boot I assume.

thanks for the help the command

grep -Pzo '(?<=\[Containments\]\[57\]\[Wallpaper\]\[org\.kde\.image\]\[General\]\nImage=)([^\n]*)' ~/.config/plasma-org.kde.plasma.desktop-appletsrc

returns

file:///home/<my-username>/.local/share/wallpapers/wp9434242.png⏎ 

how do I remove the file:// part so that it works with wal-telegram?

[kun-codes]

Quick Update: I managed to do it by this command

wal-telegram -b $(grep -Pzo '(?<=\[Containments\]\[57\]\[Wallpaper\]\[org\.kde\.image\]\[General\]\nImage=file://)([^\n]*)' ~/.config/plasma-org.kde.plasma.desktop-appletsrc)

[guillaumeboehm]

Yep my bad didn't think of that, is everything working as you need with that ?

[kun-codes]

yup, it works but I think it won't work if change the active wallpaper plugin, the one which we are working with is org.kde.image

I think you may close the comment now, I might comment again if I need some help

[kun-codes]

Thank you so much for the help

[guillaumeboehm]

Sure no problem at all
