nwg-piotr / nwg-wrapper Goto Github PK

As the title says, script doesn't refresh when I signal 8 with pkill. But instead, if I run nwg-wrapper with --sig_refresh 7 flag, it does work if I signal 7. I have no idea why. Also, 7 is just random and 8 is the default of nwg_wrapper. Any help appreciated. Thanks.

Thank you for having written this great piece of software!

I use nwg-wrapper to display the time on my desktop (and nothing else). The script run is

time=$(date +'%H:%M')
day=$(date +'%A, %e %b')

cat<<EOF
<span size="60000" foreground="black" weight="light"> $time </span>
<span size="35000" foreground="black" weight="light">  $day </span>
EOF

To appear nicely synchronous, I set the refresh time to 100 i.e. 10 refreshes per second.

I only realised a long time afterwards, that this is costs a lot of energy: 2 Watts (perhaps over proportionally so?)

My laptop's base energy consumption is around 7 Watts. Light usage uses around 10 Watts.

With nwg-wrapper -r 100 power consumption was around 2 Watts higher. nwg-wrapper -r 5000 costs only 0.1 Watts.

It seems very high, that 10fps refreshes costs, ~30% of the energy to run the rest of the OS(?)

My particular problem is solved, by setting a lower refresh rate. However, perhaps this is something that should be documented?

Is it possible, to display cava with this? Or any other program?
Thanks in advance

Hey there,
I've been searching a tool for quite a while now, that allows me to put an application window into any screen layer.
I think it would be a perfect fit for this project. It would allow me to use programs like mpv (bad example, already has a standalone implementation) as a wallpaper.
Could this be done?
Thanks!

it would be nicer if we can have a real terminal embedded in the background like i3bgwin which i've been searching for alternative since i started using sway ayear ago

The output names (like eDP-1) are unpredictable, and depend on the order in which you connect your external monitors. So the established way of binding programs and settings to outputs is to address the monitors by "Make model serial" (for example, Goldstar Company Ltd LG IPS FULLHD 604NTDV33634) which are unique. This is how Sway and Kanshi do it, for example.

Can you please add the support for this to nwg-wrapper? I'd like to be able to do nwg-wrapper -o 'Goldstar Company Ltd LG IPS FULLHD 604NTDV33634' and have the overlay drawn on the specified monitor.

Here, you can find an example of how Kanshi implements the matching logic. (Maybe you could even borrow the code from there.)

Hi.

I'd like to add some actions to a nwg-wrapper to use it as a real desktop widget. For example, open a web link when I clicks or to change workspace with mouse wheel via swaymsg, etc. Is it possible?

Thanks for the code!

I've found that if I 'sleep 0.5' after nwg-wrapper and before running swaylock/gtklock, it doesn't always display correctly. Increasing the sleep to 1 second fixes it. I daresay this depends on the CPU speed etc, but it might be a good idea to document it in the README

Feature request : to have an option to show wrapper in bottom or top layer.

infact having an option like waybar where you can send a custom signal to a module will be awesome. an id can be given to wraper window which can be used to toggle surface layer . It sounds a bit over the edge but will be an aweosme option to have

I am using nushell.

I have this in test.nu

echo test

but

nwg-wrapper -s test.nu

outputs just

tes

It seems that nwg-wrapper "eats" the last character in the file.

I use swaylock to display a random image while locked:

swaylock --daemonize --image "$IMAGE" &

Is there any way to have nwg-wrapper display some text 'on top of' that image. I tried --layer=2 but it does not display (until I unlock!).

Nwg-wrapper seems to appear on the currently active workspace. How do I draw it on another one? Can I draw it on all workspaces?

Is there a unit I can use in the CSS that is relative to my current screen size/resolution?

It is almost ready to be full-on conky support, but one crutial pice is missing - graphs.
And this "renderer" being so rightfully unixway I don't see a justification to implement something like custom protocol, no, but I also see that there is no way to render output of programs that already can draw them.
Therefore I ask for sixel suppopt, that would make it a lot easier.
And you can also render regular images with it.

I want to able able to define a config for wrapper instance in .ini file, so that this (for example) very verbose string
nwg-wrapper -s swaylock-time.sh -o eDP-1 -r 1000 -c timezones.css -p right -mr 50 -a start -mt 0 -j right -l 3 -sq 31
can become that
nwg-wrapper ~/.config/nwg-wrapper/time.ini

with config file being in that format

[wrapper]
script=swaylock-time.sh
output=eDP-1
refresh=1000
css=timezones.css
position=right
margin_right=50
margin_top=0
justify=right
layer=3
sig_quit=31

I can implement that feature.

How can we make this happen?
I upgraded python to 3.10 on my computer and NWG stopped working due to pygobject not being compiled to support python 3.9.

I wanna help. :D

There's a note in the README about layer 3, but nothing in 'nwg-wrapper --help' output.

An example, running the following script currently doesn't output anything.

#!/usr/bin/env sh
dbus-monitor --session "interface='org.freedesktop.Notifications',member='Notify',type='method_call'" | grep "method call"
