Re: Wallpaper setter for Carbon - X11 and Wayland

add a splash at startup - requires the icon to look nice! (splashes there now only show if over 250 images or if multi monitors are present)

The splash looks nice, but appears even with a small number of wallpapers, in which case I'm just waiting for it to go away. Add a minimum number of images before showing the splash? Would counting the files take too long?

EDIT: or else have the splash close itself when the main window is ready?

---
BTW these daily upgrades are great, but if you think a moment, present a moving target to people who want to try it out. It's going to be "let's wait till it settles down" for some people.

The EDIT idea is best, using a file monitor. I'll do that.

BTW these daily upgrades are great, but if you think a moment, present a moving target to people who want to try it out. It's going to be "let's wait till it settles down" for some people.

Of course, but this is a devel thread and so far there are only 4 known testers (yourself, myself , @S11 and @ceeslans)

Re: Wallpaper setter for Carbon - X11 and Wayland

^Yes, understood, and please carry on pushing out improvements as fast as they occur to you.

Just, please don't feel you're being ignored if you don't always get quick feedback.

Re: Wallpaper setter for Carbon - X11 and Wayland

Yes I have sporadic time constraints as we all often do IRL and other stuff

Just, please don't feel you're being ignored if you don't always get quick feedback.

Never at all. I'm not looking for anything but the best this program can be and even the most minor comments, like your EDIT above whipped me into a brainstorm mode.

GTK has a 'realize' signal that fires off as soon as a window pops on screen. That is the perfect way to to close the 'greeting" It doesn't need much code at all. Just added a file monitor to _greeting, fire off a change to the monitored file when the main_gui is "realize'd" and close the _greeting. It all sounds too easy but it works perfectly. So without further ado the next iter is below.

Re: Wallpaper setter for Carbon - X11 and Wayland

I have a couple of thoughts or crazy ideas.

First:
When run for the first time 'xwwall' asks for a directory and thereafter uses that directory.

thoughts or crazy ideas :

1.  could it be possible to have xwwall run using the directory it's started in?
IE:

$ cd /media/5/Wallpapers

and then

xwwall

→ → Then a little YAD script, yxwwall, could be use to start it in various locations.

2. or tell it on the command line: 

xwwall /media/5/Wallpapers/cnb

Don't mind me I'm just rambling

My terminal

 2025·01·31 @ 11:17:56 ~
   $ xwwall
Monitors:
0:
Xmonitor-0
DVI-D-0
1920
1080
0
DVI-D-0 = primary
1 outputs
GUI: MWdth=960 x MHght=715
================
/media/5/Wallpapers
EXIT="Limit"
 
 2025·01·31 @ 11:18:40 ~
   $ 

I do like this little script.

I do like this little script.

Well I can easily support this idea without much code, but I don't think a CLI switch is warranted because of the extra overhead.

Ideally, you could run it from your chosen directory at initial start (ie remove ~/.config/xwwall/xwwall.conf) and your chosen directory to run in will be saved to the new config, instead of fluffing around with GUI preferences.

I just tried this modification.

~/bin$ diff -Nur xwwall.orig xwwall
--- xwwall.orig	2025-02-01 08:38:36.932609403 +1000
+++ xwwall	2025-02-01 08:27:25.732509816 +1000

-export BGDIR="${BGDIR:-$HOME/Pictures/wallpapers}"
+if [[ "$(pwd)" == "$HOME" ]]; then 
+	export BGDIR="${BGDIR:-$HOME/Pictures/wallpapers}"
+else
+	export BGDIR="$(pwd)"
+fi
 export PROG=${0##*\/}
 export TEMP=/tmp/$PROG
 #export TEMP=$HOME/tmp/$PROG # for testing

Then I ran:

~$ cd /usr/share/backgrounds/
~$ xwwall

Here's the result:

Never mind the portrait images, they don't render too well in the GUI. Fix on the todo list.

And here's the generated config

BGDIR=/usr/share/backgrounds

So that dir will be used no matter where you start xwwall. If you want to change it just run

xwwall -d && cd /usr/share/backgrounds/xfce && xwwall # (for example)

Re: Wallpaper setter for Carbon - X11 and Wayland

My idea was in support of multiple directories under /media/5/Wallpapers some of which are:

/media/5/Wallpapers/aircraft
/media/5/Wallpapers/b-n-w
/media/5/Wallpapers/Canada
/media/5/Wallpapers/desert
/media/5/Wallpapers/halloween
/media/5/Wallpapers/Oprical·Illusion
/media/5/Wallpapers/xga

Re: Wallpaper setter for Carbon - X11 and Wayland

I think this looks a bit better as far as handling portrait images are concerned. Some users orient their monitors in portrait configuration so that base is now covered.

I actually just deleted the lines <height>'$Wdth'</height> in button_gui so with that little overhead gone I may be able to bump the image limit back to 300.

Re: Wallpaper setter for Carbon - X11 and Wayland

My idea was in support of multiple directories under /media/5/Wallpapers some of which are:

/media/5/Wallpapers/aircraft
/media/5/Wallpapers/b-n-w
/media/5/Wallpapers/Canada
/media/5/Wallpapers/desert
/media/5/Wallpapers/halloween
/media/5/Wallpapers/Oprical·Illusion
/media/5/Wallpapers/xga

The globbing in the button_gui should search subdirs up to the limit anyway, but if you have upwards of 275 in each then that won't help

EDIT - changed 300 to 275

Here you go @S11

############################ user editable #############################

######################### end user editable ############################

# build items for the combobox
ITEMS=''
for dir in ${dirs[@]}; do
 ITEMS="$ITEMS<item>${dir}</item>\n"
done

XITEMS=$(echo -e "$ITEMS")

# gui description
export UI='<window title="Choose a dir" icon-name="gtk-question" width-request="300">

eval $(gtk3dialog -p UI -c)

XDIR=${main_dir}${DIR}
echo $XDIR
# execute xwwall
[[ -d "$DIR" ]] || exit 1 # error
xwwall -d && cd $DIR && xwwall
cd -

Does pretty much what you wanted from a gtk3dialog gui instead of Yad.

Re: Wallpaper setter for Carbon - X11 and Wayland

Ok, things have sufficiently diverged from the last version to post another.

• add greeting splash closing on realize signal from MAINGUI - thanks @johnraff

• add ability to start from another directory and use that as BGDIR (requires deletion of current config). Thanks @S11

• trim some redundant code from button_gui; can now use 300 image limit again

• fix UI for portrait images

• rename 0Solid_color generated image to Solid_color so it isn't first in the UI

• if generation of the solid color image is required, make sure the dir is writable

Does pretty much what you wanted from a gtk3dialog gui instead of Yad.

Re: Wallpaper setter for Carbon - X11 and Wayland

There's another update but nothing has changed.

What? (I hear).

Well I decided to separate out the debian/ files for 2 reasons.

1. reprepro needs new source if I change something simple in debian/. Like I had to add the file dependency in case that doesn't exist.
2. Because of 1. this eases maintenance and the version only needs a bump now when there is an actual bugfix.

The debian files are in a separate branch now. https://github.com/01micko/xwwall/tree/debian

Re: Wallpaper setter for Carbon - X11 and Wayland

^I think you need to update the version if anything changes anywhere in the package, including inside debian/. Otherwise you get the situation of two different .deb files having the same version number. Not cool. Bad Things can happen.

EDIT Of course that only applies to packages that have already been uploaded for users to upgrade to. As long as the .deb hasn't been anywhere except your machine then it doesn't matter.

Agreed, having to rebuild the whole package and re-add it to reprepro for some trivial change is quite a pain. I have to do that quite often, but do try to save up changes and push out a bunch together so the version bump brings something for users.

Re: Wallpaper setter for Carbon - X11 and Wayland

Anyway, my HP lappy died, nothing from poweron . Nothing through external monitor .

So I bought a recycled Dell with a touch screen . Arrived Tuesday. I installed Boron on it and it mostly works OOTB. I think the touch screen needs either a newer kernel or some Xorg config but that is of little importance. Wayland handles it much better as it does work OOTB with labwc (using my friends Vanilla Dpup, a puppy spin based on Trixie, wayland only).  Also tried a live build of Slackware-curent (which ships labwc) and works fine there too.

Anyway, Boron it is for now and since it has 1 HDMI port and USB-C I can hook up to 3 external monitors, but for now only have 2 at hand. So I tested out xwwall and the results are as expected.

Here's pretty much what my desktop looks like ATM.

I do really need to test with 4 at some point because there are corner cases I haven't covered yet, like setting up monitors in a 2 x 2 config instead of 4 in a row.
