Hey, why did everyone stop adding something like "now back to work (scripts, yad)" at the end of their post ?
This approach made it possible to turn off the forest path, but continue to see its contours in the night darkness. Well, that is, it was possible not to stray far from the topic.

My meaning is that sometimes if I'm confronted with a problem out of my control instead of being anxious and pacing up and down, I work on a gui or program which is a productive way of dealing with stress. I am not concerned about the development of yad, simply because yad has limitations. Only by learning a full-featured gui program can the potential of an interface be fully utilised, like gtkdialog, qt etc

Yes he does have other things to keep him busy, so why does he continue development at a time like this? I presume it is to keep his mind off of stressful things out of his control.

Now back on topic!

I have this script to shuffle backgrounds.
It creates a notification icon and right click menu.
Selecting One Minute spawns run_cmd process and selecting Off kills it.
But there is a persistent sleep command process left.
It will eventually exit when the counter ends but is there a way to kill it when the parent process (run_cmd) is killed?

Code: Select all

#!/usr/bin/env bash

# add handler to manage process shutdown

[misko_2083]

Thank you but it's not a problem in function on_exit but terminating sleep when a top most option in the right click menu is selected.
It need a trap to kill it and we find out process id with the jobs, bash builtin.
Sleep will not receive the signal so we run sleep in the background and use wait to receive the signal.
And it still didn't trigger the trap until exit is called at the end.
Trap + sleep to background + wait + exit, all that only to SIGTERM sleep.

Code: Select all

    kill_sleep() {
        kill -SIGTERM $(jobs -p)
        exit #$
    }
    trap kill_sleep SIGTERM

    while true ; do
        change_wallpaper
        sleep $1 &
        wait
    done
    exit

I've changed the name of run_cmd function to wallpaper_shuffler. It's descriptive and run_cmd was only an arbitrary name.
I've split the function and made a separate one to kill the wallpaper_shuffler because why not.

Code: Select all

#!/usr/bin/env bash

# add handler to manage process shutdown

Blinking yad while waiting.

Not exactly. My point was that you can avoid sleep altogether by using yad instead of sleep. Yad can be killed very easily while it's waiting without traps. Prrof:

Code: Select all

date +%s; yad --timeout=100 & ; kill %; date +%s
1648211273
[1] 20595
[1]  + 20595 terminated  yad --timeout=100
1648211273

You get the idea. Besides, talking about yad in the "YAD - tips'n'tricks" topic has its own merits Of course, this yad wouldn't replace your main yad dialog; this yad would replace your use of sleep.

I think we're talking about different things. OK, never mind. Back to your previous question, you wrote:

[...]

https://unix.stackexchange.com/question ... p-command/

So it seems you want to avoid busy waiting in your script? This question isn't strictly about yad. It's a general shell programming question that would probably get more reads (answers) in a dedicated thread. But I read the stackexchange you posted, and it seems to me that bolt's blog post can be studied and an ingenious solution be found in it. While the bash process is reading, it's essentially off the kernel scheduler, so technically bolt's idea is not-busy-waiting as it can get. It's for linux only, it should be noted.

I can offer another idea. I'm not sure how your yad script works -- if it's supposed to run only once while multiple timeouts take place, or if it's a main loop that runs yad then "sleeps" then run yads... and so on. In either case you may be able to think of your script as an action connected to a non-expiring timer. And in puppyland where can one easily get a programmable timer with shell actions? The gtkdialog timer widget is an answer. Look at the "timer_advanced" sample script under /usr/share/doc/gtkdialog/examples/timer (also available in woof-CE on github). You can associate any shell command to run when the timer expires (in a loop if necessary). So, basically you can use gtkdialog as an equivalent of while true; do echo "wake up, do something"; sleep 60l done. You could replace yad altogether with gtkdialog or keep gtkdialog and yad separate, each running in its own process. The disadvantage of using gtkdialog (or even a separate bash process) to tick the timer outside your main yad GUI process is that you will need to distribute two separate scripts for a single application. In these cases I typically bundle the scripts together as a Rox AppDir (or you could use a portable bundle, such as an AppImage).

[misko_2083]

It runs a loop, when another right click menu item is selected it kills it and starts another loop.
The trouble was that sleep was continuing to run.
All sorted out now thanks Step.

@step I added a switch in a form dialog today.

I didn't know --changed action was added, there is --changed-action callback for switch, check, and combo fields.

Code: Select all

yad --form --field="Check":CHK --field="Switch":SW --field="Switch 2":SW "FALSE" "TRUE" "TRUE" --changed-action 'yad --text="%1 %2 %3"'

It can slow down the dialog but for some quick commands it's great.

Neither did I. I don't follow the changes in the official yad project regularly. From time to time I review them and fish for changes that can be added to gtkdialog gtk2 without too much fuss. What yad version are you using? Mine is

Next I'm going to make image set and clear from stdin in the picture dialog.

[stemsee]

I want to program a simple looping drum machine using yad as the frontend. The idea being that when a button is pressed it plays an associated sound and that re-occurs as part of a loop of 4/8/16/32 bars. So it is additive.

I think that yad --form or yad --icons might provide a usable gui.

Any input welcome. This image is yad --form with svg colour images which would be replaced with various percussion svg images

Well at least you can use it for prank call if nothing else.
Maybe a paned dialog would be good with another form in the other tab to list, play and delete selected sounds.
I don't know if there are Unicode emojis for all the instruments but it an option to consider instead of svg.
It would load faster and take less space.

Maybe it's a good idea to start backing scripts and C from me from here and elsewhere, cause they'll be gone soon.
Thought to give you heads up. I not an administrator to give you some time, it's all up to them.

Thanks for everything, it was fun.

[stemsee]

Thanks Misko!

Well, I'm not sure what you refer to by mentioning that your scripts will be gone soon ... I hope not!

-------------------

Yad features added recently include --line for use in text-info. Jumps straight to a line number.
Pango markup available for use in yad --form --field=:TXT .... this means custom fonts and colours within a form!

I want splitter position to be as a percentage which is enforced as yad gui is resized.

[stemsee]

Yad --form is a very versatile option. You could write a very interactive frontend using only yad --form.

One field type is NUM. You can set the values which determine how the input arrows operate.
for example

Code: Select all

yad --form --field="Value":NUM "10[!10..200[!4[!1]]]"

the first number 10 is the initial value displayed.
10..200 is the number range to make available
4 is the step size, so clicking the up arrow would result in 10 14 18 22 ... etc up to 200 (198). This corresponds to the seq command

Code: Select all

seq 10 4 200

the last 1 limits the decimal precision to 1 decimal place 0.1 . I do not know the maximum value possible.

[step]

[...] I do not know the maximum value possible.

Experimentally and apparently, with yad-master --form --field='Value':NUM '10[!10..200[!4[!100]]]'

screen-20220710.png (7.35 KiB) Viewed 5240 times

I can count 20 decimal places in the screenshot above.

[misko_2083]

Experimentally and apparently, with yad-master --form --field='Value':NUM '10[!10..200[!4[!100]]]'

for example

Code: Select all

yad --form --field="Value":NUM "10[!10..200[!4[!1]]]"

What's in brackets is optional. [ ]
It's a standard in all manuals.
When you have brackets inside the brackets it mean that optional value has an optional sub-value.

Simplest value is like this:

Code: Select all

yad --form --field='Value':NUM '10'

then you can set boundaries, minimal and maximum values:

Code: Select all

yad --form --field='Value':NUM '10!10..200'

next is increment, default increment is 1

Code: Select all

yad --form --field='Value':NUM '10!10..200!5'

the last one sets the precision, how many places behind zero.

Code: Select all

yad --form --field='Value':NUM '10!10..200!5!2'

if there is the last sub-value, then the increment can be a floating.

Code: Select all

yad --form --field='Value':NUM '10!10..200!0.01!2'

Code: Select all

yad --form --field='Value':NUM '10!10..200!1.01!2'

100 is a lot, 20 looks like a maximum.

Code: Select all

yad --form --field='Value':NUM '10!10..200!0.001!100'
10.00999999999999978684|

also a maximum precision is 0.0000000001

[MochiMoppel]

In this thread I'm playing around with "simple" colors. I'm using gtkdialog, but I figured that yad may also be a suitable GUI.

Experimenting with my version 0.36.2 it appears that only the yad List option is suitable. Has the advantage that the color value of a selected list item can be sent to stdout (in gtkdialog there is no pango capable list/tree widget)

Speed *seems* to be faster than gtkdialog, but that's only because yad displays the first lines while it is still busy to render the rest of the list. Gtkdialog would wait until it has rendered the whole list and only then display the result. In the end they are both slow.

What I find annoying is that yad sends the pango markup to stdout instead of the resulting text string. For following code the output would be something like <big><tt>#00c</tt></big> instead of #00c . Would require another pipe to sed to clean it up. Maybe this is fixed in newer versions? In comparison gtkdialog would output only the unformatted result but not the markup.

Code: Select all

#!/bin/bash
P='0 3 6 9 c f'
for a in $P ;do for b in $P;do for c in $P;do
	COLORS+="<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>\n<big><tt>#$a$b$c</tt></big>\n"
done;done;done
printf "$COLORS" | yad --list --separator= --column='215 "Web Safe" Colors' --column=Values --print-column=2 --geometry=300x600

Nice, thanks!

What I find annoying is that yad sends the pango markup to stdout instead of the resulting text string.

Workaround (hide (and print) dummy column without the pango markup) I found for that (EDIT: I'm using yad 0.40) :

Code: Select all

P='0 3 6 9 c f'
for a in $P ;do for b in $P;do for c in $P;do
	COLORS+="<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>\n#$a$b$c\n<big><tt>#$a$b$c</tt></big>\n"
done;done;done
printf "$COLORS" | yad --list --separator= --column='215 "Web Safe" Colors' --column=dummy --column=Values --hide-column=2 --print-column=2 --geometry=300x600

EDIT:

.... yad displays the first lines while it is still busy to render the rest of the list

Here's another variation that will bring up the list directly :

Code: Select all

P='0 3 6 9 c f'
for a in $P ;do for b in $P;do for c in $P;do
	COLORS+="<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>\n#$a$b$c\n<big><tt>#$a$b$c</tt></big>\n"
done;done;done
COLORS=$(printf "$COLORS")
OLDIFS="$IFS"
IFS=$'\n'
yad --list --separator= --column='215 "Web Safe" Colors' --column=dummy --column=Values $COLORS --hide-column=2 --print-column=2 --geometry=300x600
IFS="$OLDIFS"

^There is already a rumour in the forum circles you are making a paned dialog for this.
When can we expect the official release?

@fredx181 Great
The new version is really fast. Makes it possible to render the 512 colors pastell pattern in reasonable time.

I tried to make it even faster by skipping the printf subshell and making it POSIX compliant, so it will run in busybox ash:

Code: Select all

#!/bin/ash
P='8 9 a b c d e f'
for a in $P ;do for b in $P;do for c in $P;do

@fredx181 Great
The new version is really fast. Makes it possible to render the 512 colors pastell pattern in reasonable time.

I tried to make it even faster by skipping the printf subshell and making it POSIX compliant, so it will run in busybox ash:

Code: Select all

#!/bin/ash
P='8 9 a b c d e f'
for a in $P ;do for b in $P;do for c in $P;do
	COLORS=$COLORS"#$a$b$c|<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>|<big><tt>#$a$b$c</tt></big>|"
done;done;done
IFS=\|
yad --list --separator= --no-rules-hint --column=dummy --column='512 Pastell Colors' --column=Values $COLORS --hide-column=1 --print-column=1 --geometry=300x600 

It can select multiple columns as well:

Code: Select all

P="8 9 a b c d e f"
for a in $P ;do for b in $P;do for c in $P;do
        COLORS=$COLORS"#$a$b$c|<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>|FALSE|<big><tt>#$a$b$c</tt></big>|"
done;done;done

yad --list --separator= --no-rules-hint --column=dummy --column='512 Pastell Colors' --column=Pick:CHK --column=Values $COLORS --hide-column=1 --print-all --geometry=320x600 | awk '/TRUE/{print substr($1,1,4)}'

Mochi I gave my best but couldn't trick Fred to do something like next

Code: Select all

#!/bin/ash
OIFS=$IFS
key=`awk 'BEGIN { srand(); printf("%d%d\n", 256 * rand(), 256 * rand())}'`

P="8 9 a b c d e f"
for a in $P ;do for b in $P;do for c in $P;do
        COLORS=$COLORS"#$a$b$c|<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>|FALSE|<big><tt>#$a$b$c</tt></big>|"
done;done;done

Less "awk"ward :

Code: Select all

#!/bin/ash
P='8 9 a b c d e f'
for a in $P ;do for b in $P;do for c in $P;do
	COLORS=$COLORS"|#$a$b$c|<span font='24' bgcolor='#$a$b$c'>      <span font='12' fgcolor='#000'>text</span><span font='12' fgcolor='#fff'>text</span>      </span>|<big><tt>#$a$b$c</tt></big>|"
