The great yad hacking thread

^ your request is ok, but it's hard to say more if you don't actually ask the question.

miyo · 2018-12-21 06:33:28

Thank you ohnonot. I appreciate that.

What I'm trying to do is...create a full-screen application launcher that will close AFTER a user clicks on an application. Here is the basic command that I'm working with...

yad --icons --read-dir=/usr/share/applications --fullscreen --sort-by-name --undecorated --single-click --skip-taskbar

If I can figure this out, I will also add...

--no-buttons

...to the command.

I know that you can close yad after clicking on a button, but I can't find a way to close it after clicking on one of the icons in the window.

try xlunch. it's like gnome shell launcher for poor people (well, poor machines).

I've tried it, and it works well.

I'm just trying to keep extra packages out if I can...so that there are no packages (or as few packages as possible) not included in the system's repositories.

If I can't figure this out, I may use xlunch.

Thank you. I appreciate your time.

miyo get the process id of the yad window and use the strace to watch for SIGCHLD signal.
When yad emits the SIGCHLD signal, send SIGURS1 signal to yad.
#!/bin/bash
yad --icons --read-dir=/usr/share/applications --fullscreen --sort-by-name --undecorated --single-click --skip-taskbar --no-buttons & ICONS_PID=$!

strace -p $ICONS_PID -e trace=signal -s 32 2>&1 \
| while read -r line; do
        if [[ $line =~ "--- SIGCHLD" ]];then
           kill -s SIGUSR1 $ICONS_PID
           break
         fi
done
Signal SIGUSR1 closes the ad dialog with 0 exit status.
If you use --close-on-unfocus, yad dialog will close on alt+tab

misko_2083,

Thank you! Exactly what I was looking for! Thank you so very much for taking the time to help me.

I would be honored if you will allow me to acknowledge you for this in the future.

That is some hack. I admire the ingenuity.

It's fine by me.

Thank you.

DEPCOUNT+=1

do you want this to be an arithmetic operation? because it's not.
it will change 0 to 01, then 011 etc.

an arithmetic operation would look like this:

((DEPCOUNT+=1))

i'm guessing there are more errors, it's just the first i saw.

your doublequote fu is definitely poor.

damo · 2019-01-06 11:43:48

This is a handy tool: shellcheck

iMBeCil · 2019-01-06 12:02:47

^Quite, nice tool. Thanks damo for pointing it out!

S7.L · 2019-01-06 12:19:10

Nice tool indeed Damo. Built with Haskell too.

nice, i didn't know that.

The quotes where they need to be. Although shellcheck complains about semantics it can't check the logic. e.g. Process IDs are always integer numbers.

'm gonna take your word for it; personally I wouldn't sufficiently trust my own code to make such a bold statement.

btw, since your indices are simple integers (0-7) there is no need to declare an associative array.
a simple

APP_DESC=(
           "Music player"
           "Game"
           "Color selector"
           "Puzzle game"
           "Youtube"
           "Game"
           "Music player"
           "For screenshots"
                )

will do the same in this case.

sorry I can't help with the actual script.

Me neither I'm afraid, but you could make your yad version checking a bit simpler and more robust by using 'dpkg --compare-versions'

man dpkg wrote:

--compare-versions ver1 op ver2
Compare version numbers, where op is a binary operator. dpkg
returns true (0) if the specified condition is satisfied, and
false (1) otherwise. There are two groups of operators, which
differ in how they treat an empty ver1 or ver2. These treat an
empty version as earlier than any version: lt le eq ne ge gt.
These treat an empty version as later than any version: lt-nl
le-nl ge-nl gt-nl. These are provided only for compatibility with
control file syntax: < << <= = >= >> >. The < and > operators are
obsolete and should not be used, due to confusing semantics. To
illustrate: 0.1 < 0.1 evaluates to true.

No frills conky chooser, pretty basic but its working for me. I would like to add a killall conky there somewhere but not sure how? Suppose i could just point it to a kill script?

#!/bin/bash

yad --title="--dclick-action=CMD" --width=300 --height=200 --separator=" " --list --dclick-action="conky -c" --column=Name /home/s7/.config/conky/bar.conky.conf /home/s7/.config/conky/nl.conky.conf

Found it here: http://smokey01.com/yad/

damo · 2019-01-09 12:17:39

^ Add a button with the appropriate label and index. Then test for the return value of the dialog: if it matches the index, run the kill command.

S7.L · 2019-01-09 12:33:11

^ yes thats it, thanks damo.

--button=gtk-cancel:1 \
--button="Killall Conky":kill-conky \

S7.L · 2019-01-09 13:54:07

Yad conky chooser v0.2. Bit better looking than the list option. Bunsenlabs conky manager is a work of art, much better control. I wonder is there ability for yad to do what bl conky manager can do?

#!/bin/bash

yad --title="Conky Chooser" --form --center --on-top --width=300 --height=200 --window-icon=utilities-system-monitor --width=250 \
--field="NL-Conky":fbtn 'conky -c "/home/s7/.config/conky/nl.conky.conf"' \
--field="BL-Top Conky":fbtn 'conky -c"/home/s7/.config/conky/BL conkys/BL-Top.conkyrc"' \
--field="Bar-Conky":fbtn 'conky -c "/home/s7/.config/conky/bar.conky.conf"' \
--button="Killall Conky":kill-conky \
--button="Restart Conky":conkyrestart \
--button=gtk-cancel:1

Well, the BL conky manager uses yad as the graphical interface for the script. Yad needs something behind the scenes to operate anything constructively!

S7.L · 2019-01-13 15:22:08

Using a bit different config...

yad --width 200 --height 400 --title "CONKY" --form --center --on-top --width=300 --height=200 --window-icon=utilities-system-monitor --width=250 \
    --form \
    --field="Conky Bar:BTN" 'conky -c  "/home/s7/.config/conky/bar.conky.conf"' \
    --field="Conky NL:BTN" 'conky -c  "/home/s7/.config/conky/nl.conky.conf"' \
    --field="Conky BL-Top:BTN" 'conky -c  "/home/s7/.config/conky/BL-Top.conf"' \
    --field="Restart Conky":fbtn "conkyrestart" \
    --field="Kill Conky":fbtn "kill-conky" \

I would like to space those cancel and ok buttons better.

^just use this...

--button=gtk-close:1
