YAD - Tips

[lamplinux]

@MochiMoppel -- Thank you again !!

[lamplinux]

Is it possible for yad --entry to have several entry boxes in same window and then write each entry box input to a separate file ?

Code: Select all

dock1_name=$(yad --entry --title="Change Dock1 Window Name" --text="Enter New Dock1 name") && echo $dock1_name > /home/bobby/yadbash/beta/code/dock1name.file

Code: Select all

cd /home/bobby/yadbash/beta/code
dock1_name=$(head -n 1 dock1name.file)
yad --icons --read-dir=/usr/share/applications --monitor --single-click --item-width=70 --sort-by-name\
 --geometry="1244x153+1+592" --on-top --vscroll-policy=auto  --undecorated \
 --title="YadBash Simple Coding" --text="$dock1_name" --window-icon=/usr/share/icons/sparky/about/sparky48.png \
 --no-buttons --skip-taskbar

Well you can use the array
The trick is to use the quoted output and remove it later with xargs.

Also the internal field separator must be set for the array.
In this case newline character.

Code: Select all

#!/bin/bash
# backup IFS
OIFS=$IFS

# set IFS to newline char
IFS=$'\n'

res=($(yad --form --quoted-output --separator="\n" \
          --field=1 --field=2 \
          --field=3 --field=4 \
          --field=5))

# get exit status
out=$?

# Restore IFS
IFS=$OIFS

# OK (0), canceled (1) or closed dialog (252)
[ $out -ne 0 ] && exit 1

# for looping trough array
for i in {0..4}; do
       # write each element 0-4 into field-1 to field-5
       # xargs removes outer quotes
       echo "${res[$i]}" | xargs > /tmp/field-$((i+1))
done 

Btw this is a form dialog,

[lamplinux]

@misko, That works great - as always. Thank You !!!!

May I ask for another option to your array output ? Then I'll be able to output and read all night long.

Can the output of the array be written to the same line number of each of the "field-$" files ?

For example, Form data output is written to line 3 of each "field-$" file. So, not to over write the file, just update Line 3 of each file. I hope I'm asking this well enough.

I'm trying to use sed to accomplish this with your array but, don't fully understand what I m doing (learning though).

Bobby's attempt:

Code: Select all

# Using sed to update file - line 3 looping trough array 
for i in {0..4}; do 
       sed '3 c\ > echo "${res[$i]}"' | xargs > /tmp/field-$((i+1))

[MochiMoppel]

Instead of

Code: Select all

echo "${res[$i]}" | xargs > /tmp/field-$((i+1))

try

new=$(echo "${res[$i]}" | xargs)
sed -i "3s/.*/$new/" /tmp/field-$((i+1))

This assumes that the target file has a line 3, which sed will then replace with the field content.

[lamplinux]

new=$(echo "${res[$i]}" | xargs)
sed -i "3s/.*/$new/" /tmp/field-$((i+1))

This assumes that the target file has a line 3, which sed will then replace with the field content.[/quote]

I tried code as written but, no file writing. 5 files with words on lines 1 through 4.

I will see if I can make some (roll of the dice mod" to your code and see what I get as output.

I appreciate your help as it gets me to research what the code is doing and learn from that.

[misko_2083]

Bobby, Mochi's line should work, unless you are entering special characters in yad fields that mess up regular expressions or delimiter with sed later.
So you will want to escape them first.

Code: Select all

for i in {0..4}; do
       new="$(echo "${res[$i]}" | xargs -I {} echo "{}" | sed -e 's/[]\/&$*.^[]/\\&/g')"
       sed -i "3s/.*/$new/" /tmp/field-$((i+1))
done 

[MochiMoppel]

- removed -
(was not directly related to lamplinux's issue)

[lamplinux]

@MochiMoppel @misko, I had to remove the backslashs between --field-1, --filed-2, etc. to get it to work. But, Dang it !!!! IT NOW WORKS !!! Whoo Whoo , Thank You Both !!!!!!!!!!!

Now its time to take over the world (or maybe not) but, lots of hours of fun time creating all kinds of fully user customizable Yad powered Launching and Bash Command solutions.

Have a Great Weekend ! I am very Happy !! All Thanks to you both. Cheers !!!!!!

[lamplinux]

I discovered that I can read current data to each field to a form entry box but, if user does not change the data, it is written back to the file as - blank space.

But, if I click in each field entry box, the read data then becomes an entry and saved properly back to same file.

?? Is there a way in Yad (or bash) to emulate a user clicking a box "like auto focus" for all --field boxes in a script - automatically ?

[MochiMoppel]

???
Please give a small example.
In principle it should work, but that depends very much on your code.

At least this should work:

Code: Select all

#!/bin/bash
echo 'apple pie
banana cake
peach ice' > /tmp/testo

res=$(yad --form --separator="\n" --field=1 --field=2 --field=3 --button="Save & Exit:0"  --button=Cancel:1 < /tmp/testo)
(($?)) && exit            #exit here if exit status of yad > 0 (Save&Exit button was not pressed)
echo "$res" > /tmp/testo  #write back to file

[lamplinux]

@MochiMoppel, Thank You but, I got the below script to work. Its mainly from code you guys provided. (without it, I'd never have anything working ) But, I'm loving it ! Things are working and I'm learning too.

Now, to do this yad --dialog-separator --form --icon-read --notepad all in one window...

Since the input should be a numerical only, do I use the NUM for fields in below script ?

I also would like to have all four numbers currently saved in file, to display RO in 4 other form boxes but, I'll get that sure enough (I know I can . Would I do that in a --pane window ?

Code: Select all

#!/bin/bash 
# backup IFS 
OIFS=$IFS 
configDir=/home/bobby/yadbash/sparkypad/config
# set IFS to newline char 
IFS=$'\n'

posFile=$configDir/docks/dock-size-position/dock-size-pos
sizPosDir=$configDir/docks/dock-size-position

wideDocks=$(sed -n 1p < $sizPosDir/dock-size-pos)
hiDocks=$(sed -n 2p < $sizPosDir/dock-size-pos)
posxDocks=$(sed -n 3p < $sizPosDir/dock-size-pos)
posyDocks=$(sed -n 4p < $sizPosDir/dock-size-pos)

yad --form --separator="\n" --field="Width" "$wideDocks" --field="Height" "$hiDocks" --field="From Left" "$posxDocks" --field="From Top" "$posyDocks" --window-icon="start-here" --center --title="Dock Window Sizing" --button="Cancel":0 --button="Save":0 > $posFile

# get exit status 
out=$? 

# Restore IFS 
IFS=$OIFS 

# 0K (0), canceled (1) or closed dialog (252) 

[ $out -ne 0 ] && exit 0

Is it possible using a While True or case event to swap out the icon directory in a yad window and have it automatically updated it because it uses --monitor ?

Code: Select all

yad --dialog-sep --image="my-image.png" --width="700" --height="400" --center --window-icon=$HOME/icons/window-icon.png  --icons --read-dir=$HOME/ions/dock/config --monitor --single-click --item-width=70 --sort-by-name  --title="Config Utility" --text="Please Make Your Selection\n" --button="Config" --button="Bookmarks" --button="Music" --button="Images" --button="Videos" --button="Exit":1

Update: I could use a default directory and copy icons to and from the default directory each time a button is clicked. (Non Programmer way)

[MochiMoppel]

@MochiMoppel, Thank You but, I got the below script to work

It works? Your Cancel button does not work as it should (you assigned it the same 0 exit code as the Save button) and since you immediately redirect the yad output to $posFile without checking the exit code you will end up with an empty $posFile if you close the dialog with Alt+F4 or with the window's x button.

lamplinux, I can't see what you are asking for as you already answered some of your questions yourself.
In any case I'm a bit busy now but I'm sure some of our yad experts can help you much better than I can.

[lamplinux]

Just mentioning this because I happened upon it by accident hacking yad code

Code: Select all

export imageDir=/home/user/images

go_imagebutton() {
     cd  $HOME/bobby
     ls -l
}
export -f go_imagebutton

--button="!$imageDir/bobby.png!Bobby Button":"bash -c go_imagebutton"

Example output:

I'm trying to wrap Yad around mpv to play videos: Here's my code that does not work.

No examples on web anywhere.

(update: I have looked at code in miskos wrapper for youtube-dl but, I don't understand and its so complicated)

Code: Select all

mpv /home/bobby/Videos/* | yad2 --dialog-sep --image="/home/bobby/yadbash/sparkypad/images/side-banners/niklback-revolution.png" --undecorated --geometry=1366x560+1+1  --title="Sparkpad Images" --border=0 --skip-taskbar

Change the image paths in the script and desktop, and it should work for you too.

With kind regards,

UPDATED: Fixed the script above and in the archive to run mpv and not smplayer.

[lamplinux]

@vovchik - Thank You so much. I will use your script tonight and learn from your code.

[vovchik]

Dear lamplinux,

You will see places in the code where I commented out mpv and used smplayer instead. Originally, I did it for mpv, and everything worked that way just fine, so just commnet out the smplayer lines and use the commented-out mpv ones.

With kind regards,
vovchik

[lamplinux]

@vovchik, Yes, I noticed Committing out of mpv and switched it to mpv. Testing right now.
