Re: Wallpaper setter for Carbon - X11 and Wayland

Is the 250 image limit and no sub-folders going to be a fixed thing or is it all up in the air for future development?

I mean I could copy it to ~/bin/xwall > /bin/xwalla for my /aircraft folder:

/media/5/Wallpapers/aircraft/

YUP!  That works
Notice the 

xwalla |

in the header.

Re: Wallpaper setter for Carbon - X11 and Wayland

@Sector11 :  afaik the current name would be xwwall (so double w) since it's used in X and in wayland...

Working well here too on MX (Debian12-based) and Devuan.  Actually had a similar issue as @johnraff, but on my 1920x1080 screen the main window was too wide ... but this was solved quickly by changing the main_gui width in line 395 to  width="'$((MW-50))'">

This post near the top explains the limit: https://forums.bunsenlabs.org/viewtopic … 43#p140143

  • cap the image limit at 100. This could go higher, haven't actually tested the limit but I do know if '$TEMP/buttons' grows too big we get Argument list too long error and it crashes the program without warning. A _splash is popped notifying the user of the 100 limit and the program carries on. I *think* the limit is based on bytes, so it isn't so easy to calculate. Maybe I can count the bytes in '$TEMP/buttons' and cut off at some conservative level. The limit is around 2MB, on my 64 bit x86 system but this may (IDK) vary across arches and endianess. It's calculated by

    getconf ARGMAX

The error I was getting:

/usr/bin/gtk3dialog - Argument list too long
/usr/bin/rm - Argument list too long

The program was crashing at around 340 to 350 images for me, ok with 300 so I was a bit conservative and opted for 250.

For use of apostrophe it needs to be escaped, eg:

export MAINGUI='<window icon-name="background" title="xwall'\''s Background Choice">

I've designed the program to be called by any name you like and configs, temp files whatever will all be saved under dirs of that name.

And, whatever you called it you can replace nitrogen --restore with xwalla --restore in your autostart.

I'll be writing up a manpage soon and that will explain all the intricacies in the program.

Love your aircraft wallpapers, and what I see is barely the tip of the iceberg smile

Thanks for testing @ceeslans.

Yes that <hbox> calculation does need refining. I have to find the 'sweet spot' where no additions/subtractions are needed and go from there. I'm developing on 1920x1080 but I have a feeling, going by the feedback that 1366x768 will be sweet. Fortunately, my old HP laptop has that so I'll fire it up and see if I'm right!

BTW, nice scrot smile

EDIT0: ah the inset, yes those darker bars I should be able to fix with CSS. Thanks.

EDIT1: the following patch fixes it in main_gui

Re: Wallpaper setter for Carbon - X11 and Wayland

OK Understand about the "limit" totally missed that.
Story of my life always late for the party.  smile

I called it xwall because in the code I saw in post 16 of this thread. 

set_wall() {
    echo setting $1
    WALL=''
    if [[ -n "$WAYLAND_DISPLAY" ]];then
        if [[ -f "$HOME/.config/bunsen/wwall.conf" ]];then
            . $HOME/.config/bunsen/wwall.conf
		    OLDWALL=$WALL
	    fi
	else
        if [[ -f "$HOME/.config/bunsen/xwall.conf" ]];then
            . $HOME/.config/bunsen/xwall.conf
		    OLDWALL=$WALL
	    fi
	fi
	wall=${1##*/}

See the xwall.conf

Since I'm using it in X 'xwall' seemed appropriate for testing purposes.

I have way to many walls anyway, this might encourage me to cut back.

Re: Wallpaper setter for Carbon - X11 and Wayland

Man page (in rst format for readability)

xwwall
#####

######
Xwwall
######

:Copyright: GPLv2+
:Manual section: 1

SYNOPSIS
========
| **xwwall** [options]

DESCRIPTION
===========
**xwwall** is a graphical wallpaper setter for the X Window System
often known as **X11** and **Wayland** desktops for Linus and other
\*nix distributions. It should run in light weight desktop environments
like Openbox, fluxbox, JWM for X11 and Labwc, Sway and others for
Wayland. It supports up to 6 monitors. It is a shell script written
in **bash**.
It requires **Gtk3dialog** for the graphical user interface which is
a gtk+-3.0 based UI program that describes dialog boxes from a shell
script.
In X11 it utilises **feh** as the engine to set the wallpaper and
**xrandr** to get screen dimensions and placement of monitors.
In Wayland it uses **swaybg** to set wallpapers and **wlr-randr** for
screen dimensions and placement.

OPTIONS
=======
**xwwall** can be invoked with the following options.

-h | --help
  show help and exit.

-v | --version
  print version and exit.

--restore
  restore backgrounds at session start.

USAGE
========
Normally, **xwwall** is started from a menu entry without any options
although you could start it from a keyboard shortcut.

Main GUI
--------
The first thing you may see is a splash window warning you if you
have too many wallpapers and cuts off at a 250 limit and then a
window opens showing your wallpapers. Just select one and it will
open in a window; select the image by pressing it or **no** to reject.
You can also select if you want the image to stretch, center, tile or fit
your screen. If you do select **no** the program goes back to the main
window.
If you have more than 1 monitor the program cycles through those so you can
choose different back grounds for each of them.
Once done a confirmation window opens and you can either press **yes** or
**no**; **yes** sets your wallpaper(s) while **no** restarts the program
so you can try again.
You can exit the program safely at any stage via **Cancel**, **No** or 
the **X** (close) button of your window manager or compositor.

Preferences
-----------
There is a **Preferences** button in the bottom left of the main window
to set the following:

1. Background directory - any directory where you have read access
2. Splash checkbox screen for multiple monitors only:
   checked to show, unchecked to hide
3. Slight adjustments to width of the main interface
4. A background color for centered or transparent images

Startup
-------
You can start the program to restore your background choices from
your **autostart** or similar file with the following

``xwwall --restore``

Consult your window manager or compositor documentation for the
correct procedure.

SEE ALSO
========

gtk3dialog(1), feh(1), swaybg(1)

Test with 

~$ rst2man xwwall.1.rst xwwall.1
~$ man ./xwwall.1

Requires docutils to convert, but no need to as I'll have it converted when uploaded.

Re: Wallpaper setter for Carbon - X11 and Wayland

So, the next version

  • fixed the dark areas at bottom for main_gui

  • added a spinbutton to Preferences to adjust the width of main_gui - there's no solid way to do it programatically with gtk themes differences having a bearing

  • man page in previous post

  • Added Bunsenlabs* to wayland desktop environments (doesn't affect X)

Re: Wallpaper setter for Carbon - X11 and Wayland

Looking at the button_gui() function I was hoping to speed up the startup time when there are a lot of background images, by cutting down the read/write actions to files in $TEMP/. I collected the buttons in an array, and did a single echo out to "$TEMP/buttons" at the end. Also replaced the calls to grep for the image mimetype test with a bash glob comparison.

Disappointed to find that the startup time didn't seem much different.

But another thing that changed was the order in which the images were presented. I've no idea why, but in my revision they appear in the expected alphabetical order, but in the original some whole groups of images seem to be appearing at another place.

Just in case you'd like to play with it, here's my modified button_gui(). You could just paste it in and rename the original to button_gui_orig() or something:

# populate the main GUI
button_gui() {
	local c i j WALL V buttonsx buttons
	c=0
	shopt -s globstar
	for WALL in "$BGDIR"/*{,/**}
	do
		[[ "$(file --brief --mime-type "$WALL" )" = *image* ]] || continue # test mime
		# we take advantage of bash math here
		# for a nicish GUI width *must* be consistent
		i=$((c/4))
		V='  		<button image-position="top" tooltip-text="'"${WALL##*/}"'">
	        <variable>BG'$c'</variable>
	        <input file>'"\"$WALL\""'</input>
			<height>'$W'</height>
			<width>'$W'</width>
			<action>_output '"\"$WALL\""' &</action>
			<action>exit:BG'$c'</action>
	      </button>'
	      buttonsx[i]+="$V"$'\n'
	      c=$((c+1))
	      export TOT=$((c+1))
	      if [[ $c -ge 250 ]];then
			  export TOT=250
			  _splash "Warning: Limit of 250 images" 2 2 &
			  break
		  fi
	done
	shopt -u globstar
	for j in "${!buttonsx[@]}"
	do buttons+="		<hbox>
		${buttonsx[j]}
		</hbox>"$'\n'
	done
	echo "$buttons" > "$TEMP/buttons"
}

Re: Wallpaper setter for Carbon - X11 and Wayland

Oh, for that all to work you need the latest..

change the labwc/rc.xml windowRule

    <windowRule identifier="xwwall*" matchOnce="false">
      <action name="AutoPlace" policy="center"/>
    </windowRule>

Latest adjustments to the program:

  • W=Wdth, H=Hght

  • s/background/xwwall

  • added $PROG - in the titlebar

Looking at the button_gui() function I was hoping to speed up the startup time when there are a lot of background images, by cutting down the read/write actions to files in $TEMP/. I collected the buttons in an array, and did a single echo out to "$TEMP/buttons" at the end. Also replaced the calls to grep for the image mimetype test with a bash glob comparison.

Disappointed to find that the startup time didn't seem much different.

But another thing that changed was the order in which the images were presented. I've no idea why, but in my revision they appear in the expected alphabetical order, but in the original some whole groups of images seem to be appearing at another place.

Just in case you'd like to play with it, here's my modified button_gui(). You could just paste it in and rename the original to button_gui_orig() or something:

# populate the main GUI
button_gui() {
	local c i j WALL V buttonsx buttons
	c=0
	shopt -s globstar
	for WALL in "$BGDIR"/*{,/**}
	do
		[[ "$(file --brief --mime-type "$WALL" )" = *image* ]] || continue # test mime
		# we take advantage of bash math here
		# for a nicish GUI width *must* be consistent
		i=$((c/4))
		V='  		<button image-position="top" tooltip-text="'"${WALL##*/}"'">
	        <variable>BG'$c'</variable>
	        <input file>'"\"$WALL\""'</input>
			<height>'$W'</height>
			<width>'$W'</width>
			<action>_output '"\"$WALL\""' &</action>
			<action>exit:BG'$c'</action>
	      </button>'
	      buttonsx[i]+="$V"$'\n'
	      c=$((c+1))
	      export TOT=$((c+1))
	      if [[ $c -ge 250 ]];then
			  export TOT=250
			  _splash "Warning: Limit of 250 images" 2 2 &
			  break
		  fi
	done
	shopt -u globstar
	for j in "${!buttonsx[@]}"
	do buttons+="		<hbox>
		${buttonsx[j]}
		</hbox>"$'\n'
	done
	echo "$buttons" > "$TEMP/buttons"
}

I probably won't get time for a day or 2. Anything that speeds things is a good thing IMO. smile

Re: Wallpaper setter for Carbon - X11 and Wayland

^I was hoping that cutting down on the file access while iterating over a collection of over 100 wallpapers would make a significant speed difference, but it didn't seem to. Still, the array method might be preferable anyway.

---
Oh yes, line #439, that [[ $NUM > 1 ]] needs to be [[ $NUM -gt 1 ]], as you have it elsewhere.

added a spinbutton to Preferences to adjust the width of main_gui - there's no solid way to do it programatically with gtk themes differences having a bearing

In my 1024X768 VM I had to wind it up to +48 to lose the horizontal scrollbar, but it works. smile

What also worked here is to make the buttons a bit narrower when setting Wdth, from $((X / 9)) to $((X / 10)), but that might not look so good with wide displays or different gtk/openbox themes.

change the labwc/rc.xml windowRule

    <windowRule identifier="xwwall*" matchOnce="false">
      <action name="AutoPlace" policy="center"/>
    </windowRule>

This worked too on Wayland.

One OOPS! In the man page:

**xwwall** is a graphical wallpaper setter for the X Window System

Linus Torvalds would probably smile but it's really:

Re: Wallpaper setter for Carbon - X11 and Wayland

Trying to reduce the width and height of the xwwall window and images, by tinkering with the width/height values in the script.
On my 1920x1080 screen, thumbnails in the main_gui window are now 160px wide - whereas those in the selection- and confirm_gui are both 320px wide.
In order to adjust the main_gui window width, I had to increase the spinbutton range-max (#487) value, as it needs a little higher value than than -200 as scripted.

Wondering whether it would be possible to skip the last confirm_gui window --> and set the wallpaper when pressing the selection image instead?

I can change to [+-]300, no problem.

Definitely and a good idea for single monitor setups. The confirm_gui is really designed with multi-monitor setups in mind, so I'll work on that soon.

Thank you both for feedback.

Re: Wallpaper setter for Carbon - X11 and Wayland

I've migrated the code to Github. https://github.com/01micko/xwwall

Direct link to xwwall script

If you like you can install it under /usr/local using the Makefile. DESTDIR and uninstall are supported.

Changes
------------

  • Replaced button_gui with @johnraff's array version. I think it is a few milliseconds faster which may show up better on older kit and especially in X11. I find the script is noticeably faster in wayland but that's more the platform than the script.

  • remove need for 'confirm_gui' when on a single monitor.

  • fix manpage typos thanks to the Poty Gink, @Sector11 smile

  • add a another config otpion to adjust height of GUI and width of images thanks to @ceeslans. May be a little fiddly but works well and once set you can forget.

  • removed a little more redundant code
