YAD - Tips

[stemsee]

I am interested to know what other ways I can utilise exclusively (time slots) a yad dnd panel which is part of --notebook --paned gui.

So far I am using tee together with a variable which that yad dnd element is piped to. This gives two pipes out of the dnd. When I want only the tee output I redifine the variable to tap=/dev/null . It works. But I found that I can also define the output of the dnd by association, dndout=$(yad --dnd | tee /tmp/outdnd &>$tap &) &, and seems to work without affecting its function in the --notebook gui.

I want to know how many pipes I can feed to without using tee... is this possible in theory

Code: Select all

dndout=$(yad --plug=$$ --tabnum=2  --dnd &>$tap &>$apt &>$pat &) &

currently

Code: Select all

yad --listen --plug=$$ --tabnum=1 --item-separator=" " --form --cycle-read --columns=2 --field=A --field=0 --field=1 --field=2 --field=3 --field=4 --field=5 --field=6 --field=7 --field=8 --field=9 --field=10 <& 2 &
yad --plug=$$ --tabnum=2 --text="\t\t\t\t\t\t\tDnD panel\n\tClick a button\n\tThen Drag the mac address here!" --dnd | tee $pat 1>$tap &

Hi there Stemsee, long time no chat

Thinking that this kind of redirection &>$tap &>$apt &>$pat is possible only in zsh.

About the paned dialog, what is the purpose of the ten fields in the first tab?

[step]

Hi stemsee, so you want to fan output to N taps using shell only? What about piping to a "while read; do" loop and echoing to as many files as you need inside the body of the loop? Something like:

Code: Select all

dndout=$(yad --plug --tabnum=2 --dnd |
while read s; do
  echo "$s" >> $tap; echo "$s" >> $apt; echo "$s" >> $path; echo "$s"
done)

Is it possible for yad to display all file names in a folder, i.e. /usr/share/applications... like firefox.desktop google-chrome.destop, etc. and have a chck box next to each listed file displayed in list.

Then user checks the box of each file they want to use in a home folder (directory).

Then upon button click - checked files are then copied from /usr/share/applications to /home/user/yadlauncher/applications ?

Yes. Here's a template you can elaborate on:

Code: Select all

cd /usr/share/local/share/applications/ && ls *.desktop | yad --center --list --column= --checklist --column=file | cut -d'|' -f2 | xargs echo cp -t /dest/dir 

This will print the copy command that would be executed. If that's OK delete "echo" from the command to get a working version. Of course change /dest/dir, absolute path to the destination directory, as you see fit.

If you then want to display an icon grid for the files in /dest/dir use:

Code: Select all

yad --icons --read-dir=/dest/dir

[lamplinux]

Step, Thank You Very much!! I will work on this tomorrow. I will sleep well tonight knowing it will be a productive day having received your help !

[MochiMoppel]

@lamplinux As always step was one step ahead

Normally the --file dialog is used for such task. That's what it is made for:

Code: Select all

TARGET="/home/user/yadlauncher/applications"
CHECKED=$(yad --title="Please select (multiple) files" --file --geometry=700x500 --button="Copy to $TARGET":0 --button=Cancel:1 --file-filter=*.desktop --multiple --filename=/usr/share/applications/* )
(($?)) && exit
IFS=TMP IFS='|'
cp -t "$TARGET" $CHECKED 
IFS=$TMP

The --list dialog with checkboxes is a bit more complicated. I used the sed command to add default values for the checkbox column (without it the dialog would display only every 2nd file of the source directory):

Code: Select all

IFS=TMP IFS=$'\n'
TARGET="/home/user/yadlauncher/applications"
SOURCE=/usr/share/applications
cd "$SOURCE"
SOURCE=$(ls *.desktop | sed 's/^/FALSE\n/')
CHECKED=$(yad  --title="Please select (multiple) files" --list --print-column=2 --separator=$IFS --checklist --geometry=400x600 --column="" --column=Name --button="Copy to $TARGET":0 --button="gtk-cancel":1 $SOURCE) 
(($?)) && exit
cp -t "$TARGET" $CHECKED
IFS=$TMP

If it hasn't to be yad you should also consider Xdialog. The beauty here is that you can click anywhere in the line and don't have to target a tiny checkbox:

Code: Select all

IFS=TMP IFS=$'\n'
TARGET="/home/user/yadlauncher/applications"
SOURCE=/usr/share/applications
cd "$SOURCE"
SOURCE=$(ls *.desktop | sed 's/.*/&\n&\nno/')
CHECKED=$(Xdialog  --title="Please select (multiple)files" --ok-label=Copy --stdout --no-tags  --separate-output --checklist  "Copy selected file to\n $TARGET" 400x600 0 $SOURCE ) 
(($?)) && exit
cp -t "$TARGET" $CHECKED
IFS=$TMP

@MochiMoppel

Thank You. I will use your code tonight and see what it does. I've been using yad for some years now but, I lack experience with bash.

Thank You for code help.

[lamplinux]

Thank you @Step & @MochiMoppel for yad + bash code help.

I would like to expand on this to do the following. Now that I have a starting point I know I can eventually get to what I want to offer to others. (I'm just very slow at it)

Expanding Yad Favorite app launching:

1. Check mark shown for all .desktop files present in base directory.

2. Option for user to remove 1 or more .desktop file from base directory. (If check mark remove, its .desktop file is remove from base directory),

3. Display icon next checkbox for all possible /usr/share/applications/*.desktop files.. (For Example, Reading 3rd line, 5th character and all characters to the right of 5th character to end of line of each icon.desktop file. --- 5th line - "icon=internet_icon).

4. Dropdown or I guess, DND, to allow user to assign each .ldesktop file to specific folders. For example, Internet, Network, Personal, Sparky, Yad, etc.

Does my mod concept sound useful.. What else could this yad script offer to users for each launching of apps, websites, settings, bash commands like "sudo apt update", etc ?

It possible for yad to display all grocery item names
and have a check box next to each item displayed in list.
Then the user checks the box of each item they want to buy.
Then upon button click - checked files are then copied to a file

it uses Anthony Tekatch's shopping list.txt file (which can be edited
with your local grocery store's aisle numbers or name with Puppy's Geany editor)
License: GPL
http://unihedron.com/projects/grocget/d ... 0.6.tar.gz
http://freshmeat.sourceforge.net/projects/grocget
Anthony's original program needs Python, and some Gnome modules but just his list.txt file
(which has two fields: the aisle number followed by the grocery item's name)
can be used from his tar file in this yad script example (to save some initial typing)

and a little editing of MochiMoppel's original Xdialog script from:
http://www.murga-linux.com/puppy/viewto ... 31#1016071

the final resultant file: todaysgroceryshoppinglist.txt can be printed out
or emailed or USB'ed to a smart phone for use in the local grocery store so you
only walk on aisles that have what you are buying.

Thank you: Anthony Tekatch and MochiMoppel

@lamplinux: Yad may pose some problems. Placing icons next to the checkmarks may be one of them. Earlier in this thread I posted a demo for an icon finder. For this particular use case it is nice to show the icons in their original size, but in your case you might want to have them automatically resized to fit the row height. AFAIK yad can't do that.

[lamplinux]

@MochiMoppel - all my desktop icons could be copied and resized automatically to say 16px. Then use the reduced size icons. Would that work ?

Also, I am using Your's and @Step code to also select music files too but, with one issue. I'm using mpg123 (in the background). I stop the play with a killall mpg123 command. The files display in Yad list but, fail to copy to base directory because of blank spaces.

How could I handle blank spaces in Awk so the selected files copy to the target directory ?

Thanks for your help.

Thanks for your help.

if you're using something like

Code: Select all

ls *.mp3 | xargs cp -t /dest/dir

change that to

Code: Select all

printf "%s\0" *.mp3 | xargs -0 cp -t /dest/dir

This will take care of filepaths with spaces in them

[MochiMoppel]

Depends. I'm not sure what you mean by "copied and resized automatically". If you manage to find the full paths of the .desktop icons, copy and resize those icons and then reference them in your yad list it should work.

Also, I am using Your's and @Step code to also select music files too but, with one issue. I'm using mpg123 (in the background). I stop the play with a killall mpg123 command. The files display in Yad list but, fail to copy to base directory because of blank spaces.

If you refer to my code please explain which of the 3 demos fail. They would fail if SOURCE path contains spaces (in which case you would have to put the path - like TARGET - in quotes, e.g SOURCE="/my/music folder").Since files display in the list as you wrote, this can't be the reason

How could I handle blank spaces in Awk so the selected files copy to the target directory ?.

Awk? Where does awk come into play?

For this particular use case it is nice to show the icons in their original size, but in your case you might want to have them automatically resized to fit the row height. AFAIK yad can't do that.

yad can scale the icons with list display, but only if you specify the name of the icon only, without extension (instead of full path) and should be in icon search path (e.g. /usr/share/pixmaps), so then instead of e.g.

Code: Select all

 /usr/share/pixmaps/browser.png

Just:

Code: Select all

browser

But probably not very useful info for what @lamplinux wants, In case of listing .desktop files, on puppy the "Icon=...." has mostly the full path specified, so icons may show with different sizes then.

I ran without the list.txt file being there and as you could imagine, my output was a mess. So I added the following after your DIR= line but before your SOURCE= line. To be exact, my if statement started on line 29.

I'm glad you were able to get Anthony Tekatch's
list.txt file extracted. (Others who are interested can copy
and paste it from your above post.)

I, myself, was very impressed with the "professional look" of
MochiMoppel's Xdialog command's window.
(I've attached a screen shot to show this.)

I downloaded grocget-0.6.tar.gz file and clicked on it and scanned its
contents and then selected his "grocget-0.6/list.txt" only and extracted just that
to a small directory I made called "grocery_shopping_for_Linux_stuff" on my
Windows NTFS drive. I put just the "list.txt" and my "yad_groceryshoppinglist.sh"
files in that directory.

I brought that directory up in a ROXfiler window and with a right click, choose
"window" then "terminal here". In my roxterm terminal window which opened, I entered
my script name with ". ./":
. ./yad_groceryshoppinglist.sh
after many cycles of trying, Geany editing and retrying "window" then "terminal here",
I wanted to share the versatility of MochiMoppel code.

Perhaps MochiMoppel's Xdialog script showing how to select file names and this
yad_groceryshoppinglist script showing selecting lines from within one file
will inspire others to code even more useful little script programs.

Hi all, your code worked fine. I was trying to use awk to copy files with spaces and had problems. I will work with your code this weekend and learn more about what it does.

@step, your code with printf did the trick with copying files with spaces. Thanks !

Thanks Everyone for your help. I just need to test more to see what all the code does. I'm learning and still a newbie.

Will come back next week after testing, tweaking, learning. Thanks Again !!!! You all are very much appreciated.

[lamplinux]

Experimenting with both mpg123 and mpv I need to send a keystroke to advance to next song.

mpg123 requires the "f" key to go to next song. mpg123 -C *.mp3

mpv requires the "Return" key to go to next sone. mpv *.mp3

Can not understand why when I click on Next Track Music button, another instance of mpv is executed.

Code: Select all

#!/bin/bash

play_mpv(){
cd /home/bobby/yadbash/sparky-launcher/music/
mpv *.mp3
}
export -f play_mpv


yad --form \
 --field="Play Random Music:BTN" "bash -c play_mpv" \
 --field="Next Track Music:BTN" "xdotool key Return" \
 --field="STOP MUSIC:BTN" "killall mpv"

[MochiMoppel]

Can not understand why when I click on Next Track Music button, another instance of mpv is executed.

Because when you click the button, yad becomes the active window and the xdotool sends a Return keystroke - without further instructions of course to the active window. Yad receives the keystroke and applies it to the first button and starts another instance of mpv. You should be happy that the Return key does not go to the button you just pushed as this would result in an infinite loop.

What you need to do is let your command activate the mpv window and then send Return.
