YAD - Tips

[achim]

Hello everybody,

How can I move with the keyboard instead of the mouse in a selection dialog created with "--file-selection"?

Best regards, Achim

Tab to change the focus to another widget, then arrow keys up and down.
To get to the right pane when you open a yad file selection press shift+tab.

Say I have a folder holding icons showing temperatures from 10C to
105C. My bash script finds the temp and selects the appropriate icon.
How using yad can I place the icon in the tray? I would arrange to do
this "find temp and display icon" loop every few seconds.

Edit: The icons are from an old tempicon app having .svg extensions,
if that's a concern or consideration. Maybe they can be converted if
necessary.

Fredx181, if you want to make one, even simpler version of yradio,
you can use the list for navigation between the radio categories and stations.

Here's an example with the notification icon.

Hey Misko, thanks anyway, but I have no idea how to implement your code in yradio, if you feel like it sometime, maybe you want to do it ?
(also I'm not sure if I understand what the improvement exactly can be , but it sounds promising what you're suggesting )

Any pointers will be appreciated.

I have security cameras that use proprietary Web view apps but, if my internet is down I can not see my camera output. I can though, capture snapshots from each camera locally using a URL -- *.cgi script in each camera. Here is the flow I want to acomplish.

1. Use wget to get image form camera http:/admin:pw@192.168.1.100 (Done, this works)

2. wget saves images to snampshot.cgi.1, snapshot.cgi.2, snapshot.cgi.3, etc. (every 3 seconds). (Done)

Need to do this:

A. Rename files:
rename snapshot1.cgi.1 ---> camera0000001.jpg
rename snapshot1.cgi.2 ---> camera0000002.jpg
rename snapshot1.cgi.1 ---> camera0000003.jpg
etc........

Use DevedeNG to make a DVD video out of the files, 1 hour long video file.

This will work on Amcrest Cameras and many others. Once it is done, I'll give credit to all and put it on Github under GPL License 2.1+.

I am just stuck at the Renaming part.

Thanks, Bobby

using yad?

[MochiMoppel]

A. Rename files:
rename snapshot1.cgi.1 ---> camera0000001.jpg
rename snapshot1.cgi.2 ---> camera0000002.jpg

Try

Code: Select all

cd /path/to/snapshots
for f in snapshot1.cgi* ; do mv $f $(printf 'camera%07d.jpg' ${f##*.}); done

Code: Select all

mkfifo /tmp/PIPE
exec 4<> /tmp/PIPE

yad --notification --listen <& 4 &
echo "icon:/path/105c.svg" >/tmp/PIPE

svg may need size limit.

EDIT: to clarify, only the 'echo "icon:/*.svg" >/tmp/PIPE' statement needs to be in your loop, which means the icon name needs to be represented with a variable.

Code: Select all

echo "icon:${PATH}${temp}.svg" >/tmp/PIPE

you can do notificaion text in he same way and a menu.

Code: Select all

echo "tooltip:temperature is ${temp}" >/tmp/PIPE
echo "menu:Refresh Temp!bash -c command!/path/to/icon.svg|" >/tmp/PIPE

[rufwoof]

Rather than storing pre-created svg temperature value files, if you have image magick installed then you could create images dynamically

Code: Select all

# Requires imagemagick

temp=113  # temperature value hard coded here

convert \
    -size 32x32 \
    xc:lightblue \
    -font DejaVu-Sans \
    -pointsize 18 \
    -fill black \
    -gravity center \
    -draw "text 0,0 '${temp}'" \
    image.png

That creates a .png, so you'd have to amend the code that stemsee posted to

Code: Select all

echo "icon:/path/image.png" >/tmp/PIPE

Thanks for your inputs. Meanwhile, SFR provided me with a working
model of the yad method of placing icons on a tray. I've put up my
latest version 1.4 of traytemp in the utilities section.

Yad notification screen rotation. Left Click icon for normal. Right click for menu.

Code: Select all

#!/bin/sh
connected=`xrandr | grep connected | cut -f1 -d' ' | head -1`
yad --notification --listen --text="Rotate Screen" --tray-icon="/usr/share/pixmaps/picdrop.png" --command="bash -c 'xrandr --output $connected --rotate normal'" --menu="Rotate Left!xrandr --output $connected --rotate left!|Rotate right!xrandr --output $connected --rotate right!|Rotate Inverted!xrandr --output $connected --rotate inverted!|" 

edit
this version changes the trray icon to indicate rotation, using up down left right arrows (make your own!)

Code: Select all

#!/bin/sh
mkfifo /tmp/RPIPE
exec 3<> /tmp/RPIPE
export connected=`xrandr | grep connected | cut -f1 -d' ' | head -1`
function left (){
	xrandr --output $connected --rotate left
	echo "icon:/usr/share/pixmaps/left.png" >/tmp/RPIPE
}; export -f left
function right (){
	xrandr --output $connected --rotate right
	echo "icon:/usr/share/pixmaps/right.png" >/tmp/RPIPE
}; export -f right
function inverted (){
	xrandr --output $connected --rotate inverted
	echo "icon:/usr/share/pixmaps/inverted.png" >/tmp/RPIPE
}; export -f inverted
function normal (){
	xrandr --output $connected --rotate normal
	echo "icon:/usr/share/pixmaps/normal.png" >/tmp/RPIPE
}; export -f normal

yad --notification --listen --text="Rotate Screen" --tray-icon="/usr/share/pixmaps/normal.png" --command="bash -c normal" --menu="Rotate Left!bash -c left!/usr/share/pixmaps/left.png|Rotate right!bash -c right!/usr/share/pixmaps/right.png|Rotate Inverted!bash -c inverted!/usr/share/pixmaps/inverted.png|" <&3

EDIT: I added /etc/rotate file to remember last orientation so it could be reused easily/auotmatically

Code: Select all

Hello everybody,

The code "YAD Wrapper for youtube-dl" by Misko-2083 (http://murga-linux.com/puppy/viewtopic. ... &start=300) needs to be changed slightly. The URL is no longer valid. Unfortunately I do not know the new address, so I need your help for the correction.

Many thanks

Code: Select all

...
function ytdl_version () {
    echo "#Checking youtube-dl version" >> "$ytdpipe"
    wget --spider --user-agent="Mozilla/5.0 Gecko/20100101" --timeout=30 -q "https://rg3.github.io/youtube-dl/" -O /dev/null
    if [[ "$?" -ne "0" ]]; then
       echo "#Can't connect to youtube-dl server site" >> "$ytdpipe"
    fi
    ytdlcv=$(youtube-dl --version)
    ytdllv=$(wget -O- -q "https://rg3.github.io/youtube-dl/update/LATEST_VERSION")
    if [[ "$ytdlcv" == "$ytdllv" ]]; then
   echo "#youtube-dl is up-to-date"  >> "$ytdpipe"
    else
   echo "#youtube-dl update is available" >> "$ytdpipe"
    fi
} 
...

[fredx181]

Hi achim, can't see what's wrong with the code (or url), to test I removed the writing to pipe ( >> "$ytdpipe") and it checks ok for me if a youtube-dl update is available or not.

Code: Select all

function ytdl_version () {
    echo "#Checking youtube-dl version"
    wget --spider --user-agent="Mozilla/5.0 Gecko/20100101" --timeout=30 -q "https://rg3.github.io/youtube-dl/" -O /dev/null
    if [[ "$?" -ne "0" ]]; then
       echo "#Can't connect to youtube-dl server site"
    fi
    ytdlcv=$(youtube-dl --version)
    ytdllv=$(wget -O- -q "https://rg3.github.io/youtube-dl/update/LATEST_VERSION")
    if [[ "$ytdlcv" == "$ytdllv" ]]; then
   echo "#youtube-dl is up-to-date"
    else
   echo "#youtube-dl update is available"
    fi
}
ytdl_version

Output:

Code: Select all

# ytdl_version
#Checking youtube-dl version
#youtube-dl is up-to-date

Hello Fred

I experimented a bit with the code and made a mistake. I have found this now and everything is working again.

Thanks again!

Hello,
Can yad accept input at timeout, without hitting enter or OK? Like this:

Code: Select all

z=`Xdialog --timeout 5 --interval 5000 --stdout --inputbox "Enter a number and wait" 0 0` ; echo $z

Sorry if the answer is somewhere in this long thread; I looked Thanks in advance

[step]

I don't think it can but I'll be happy to stand corrected. There's an --always-print-result option, but the yad manual says

--always-print-result
Print result for any of the return codes. This options doesn't work if timeout was reached or Escape was pressed.

Nice

[Wognath]

SIGUSR1: Close dialog with 0 exit code.

Code: Select all

 yad --entry > /tmp/z & sleep 5 ; pkill -SIGUSR1 yad ; z=$(</tmp/z)

If more than one yad running:

Code: Select all

yad --title unique    ...    pkill -SIGUSR1 -f "yad.*unique"

[phat7]

Code: Select all

z=$(yad --entry & sleep 5 ; pkill -SIGUSR1 yad)

This may work even better:

Code: Select all

z=$(timeout -s SIGUSR1 5 yad --entry)
