Help me to fix a genmon script

sonycdr · 2021-04-11 02:43:47

I'm using a openbox system with a tint2 panel. In this panel I had a little 'executor' to show me the info about audio tracks: author and song's name.

The executor shows the output of playerctl. Well, the command in tint2 is this:

{ echo "$(playerctl metadata artist | awk '{print "♫ " $0 ""}')"; echo - "$(playerctl metadata title | awk -v len=48 '{ if (length($0) > len) print substr($0, 1, len-3) "..."; else print; }')"; } | tr "\n" " "

I want charge this command on a genmon instance in my xfce panel, so I create a bash script but don't works:

#!/usr/bin/env bash

{ echo "$(playerctl metadata artist | awk '{print "♫ " $0 ""}')"; echo - "$(playerctl metadata title | awk -v len=48 '{ if (length($0) > len) print substr($0, 1, len-3) "..."; else print; }')"; } | tr "\n" " "

In genmon I set the name of the script file that is a executable file, this file is in my binaries' path and works when I call it from the terminal.

Please, has anyone a tip for to achieve that this command works?

Your script works fine for me. What version of the genmon plugin are you using?

Maybe try this version instead - it might work better:

#!/usr/bin/env bash

echo "$(playerctl metadata artist | awk '{print "♫ " $0 ""}') - $(playerctl metadata title | awk -v len=48 '{ if (length($0) > len) print substr($0, 1, len-3) "..."; else print; }')" | tr "\n" " "

ToZ thank you for your attention. I've achieved make run the script in my genmon instance, but I need clarify some issues.

Firstly the OS specs:

OS: Debian 10
genmon: 4.0.1-2

Well, I create the bash script (eg. MUSIC) in my local folder for binaries, this folder is added in my $PATH so when I call to the script on terminal it works. Don't forget that this bash script is executable (chmod +x MUSIC). Then I create the instance of genmon and type in the order's place MUSIC, but genmon can't read it.

But this words made me think:

So in genmon I change the command:

Before: MUSIC
After: /home/userpc/.local/bin/MUSIC

Now, the script works but I have a question: Is necessary in genmon type the whole path of the script when it is in local folder?

PS: This script is very simple, but is powerful. In tint2 I can use mouse actions over the plugin, I don't know is possible to achieve the same behavior with xfce panel and genmon plugin, but playerctl/tint2 let me play, pause or change song with clics. How to use clic events with genmon plugin for pause/play music or active other playerctl feature?

for Debian /usr/local/bin is usually first in the path. It requires root to place your script, but I'm in the habit of placing them there and calling them MUSIC.genmon. So in the genmon config the command is simply music.genmon. Yes, I'd lower case the name, personally. This also puts this in place for other users, if helpful. Any reference in the script can be ~/ for all users.

CwF, I type MUSIC in uppercase only here for a didactic purpose. My original file is in lowercase, but I have this file without extension:

My file: music
Your file: music.genmon

But with extension .genmon the script don't work.

Your other advice don't work for me too, when I type ~/.local/bin/music, genmon can't read the script.

I mean /usr/local/bin/music.genmon not ~/usr/bin. Check your path for /usr/local/bin. That is root area not within home.

I mention ~/ within the script to reference data with home if so. The script in global /usr/local/bin then works for all users but may access data within a user's home, then the ~/ reference.

Only the panel genmon uses music.genmon. So music.genmon is not useful on the cli. the genmon 'contains' the script for genmon purpose, not in cli executable form, yes?

something like;

echo -e "<txtclick>your script</txtclick>"

Maybe you need to tell genmon to use the shell.
The command for Genmon

/usr/bin/env bash -c "~/.local/bin/music"

in the script genmon calls, you tell genmon what text to display <txt>text</txt> which script launch on click <txtclick>bash -c script</txtclick>
As for using playerctl you can do a bit of scripting and yad as the UI.

~/.local/bin/music

#!/usr/bin/env bash
# Note: best to set the monospace font for this genmon

vol="$(/usr/bin/amixer get Master | /usr/bin/grep "\[on\]" | /usr/bin/sed 's/[][%]//g')"
vol=( $vol )

# check if pulseaudio is running, set CURVOL accordingly.
[ $(pidof pulseaudio) ] && CURVOL="${vol[4]}"
[ $(pidof pulseaudio) ] || CURVOL="${vol[3]}"

  function _pbar {
    let _progress=(${1}*100/${2}*100)/100
    let _done=(${_progress})/10
    let _left=10-$_done
    _fill="$(printf "%${_done}s")"
    _empty="$(printf "%${_left}s")"
    printf "<txt>%s[%3d%%]%s</txt>" "${_fill// /▇}" "${_progress}" "${_empty// /▇}"
  }
_end=100

_pbar ${CURVOL} ${_end}

# here you call yad UI when the genmon is clicked
echo "<txtclick>/usr/bin/env bash -c \"~/.local/bin/yad_genmon_audio.sh\"</txtclick>"

yad_alsa_audio

yad_genmon_audio.sh requires yad, xdotool and alsa-utils
This yad dialog uses sets the global alsa volume, because I feel lazy and only recycled some lines from the other scripts.
With a little scripting you can use the progress bar to set the volume with playerctl.
