how to format multi-line command module output

[tomsoutherland]

How can I format format the output of a command which returns multiple lines?

$ zfs list -o space|grep -e "ROOT/" -e "homes/"|awk '{print $1 " Used "$3 " Snaps "$4 " DS "$5}'
zroot/ROOT/arch-gnome Used 30.1G Snaps 5.71G DS 24.4G
zroot/ROOT/arch-kde Used 46.9G Snaps 29.2G DS 17.6G
zroot/ROOT/arch-proto Used 2.45G Snaps 2.91M DS 2.45G
zroot/ROOT/debian-gnome Used 12.8G Snaps 4.66G DS 8.18G
zroot/ROOT/debian-sid Used 35.5G Snaps 16.8G DS 18.8G
zroot/homes/root Used 2.94M Snaps 1.43M DS 1.52M
zroot/homes/toms Used 573G Snaps 25.4G DS 261G
zroot/homes/toms/Games Used 287G Snaps 32.7M DS 287G

The result when printed is the first line of output will be formated but the remaining lines are not. I've even tried to generate json output and use the defined fields:

$ ./fastfetch-zfs.sh 
{
{"zfsfs": "zroot/ROOT/arch-gnome", "zfsfsval": "Used 30.1G Snaps 5.71G DS 24.4G"},
{"zfsfs": "zroot/ROOT/arch-kde", "zfsfsval": "Used 46.9G Snaps 29.2G DS 17.6G"},
{"zfsfs": "zroot/ROOT/arch-proto", "zfsfsval": "Used 2.45G Snaps 2.91M DS 2.45G"},
{"zfsfs": "zroot/ROOT/debian-gnome", "zfsfsval": "Used 12.8G Snaps 4.66G DS 8.18G"},
{"zfsfs": "zroot/ROOT/debian-sid", "zfsfsval": "Used 35.5G Snaps 16.8G DS 18.8G"},
{"zfsfs": "zroot/homes/root", "zfsfsval": "Used 2.94M Snaps 1.43M DS 1.52M"},
{"zfsfs": "zroot/homes/toms", "zfsfsval": "Used 573G Snaps 25.4G DS 261G"},
{"zfsfs": "zroot/homes/toms/Games", "zfsfsval": "Used 287G Snaps 32.7M DS 287G"},
}

This ends up not displaying anything at all.

Is this even possible?

You have to join them into a single line

BYW there is a module that prints zpool info. It doesnt print datasets though.

I'm using the zpool mod already and thank you for that. I've converted the output so all json is a single line but the fields are not getting interpreted:

$ ./fastfetch-zfs.sh 
{"zfsfs": "zroot/ROOT/arch-gnome", "zfsfsval": "Used 30.2G Snaps 5.71G DS 24.4G"}, {"zfsfs": "zroot/ROOT/arch-kde", "zfsfsval": "Used 46.9G Snaps 29.2G DS 17.6G"}, {"zfsfs": "zroot/ROOT/arch-proto", "zfsfsval": "Used 2.45G Snaps 2.91M DS 2.45G"}, {"zfsfs": "zroot/ROOT/debian-gnome", "zfsfsval": "Used 12.8G Snaps 4.66G DS 8.18G"}, {"zfsfs": "zroot/ROOT/debian-sid", "zfsfsval": "Used 35.5G Snaps 16.8G DS 18.8G"}, {"zfsfs": "zroot/homes/root", "zfsfsval": "Used 2.94M Snaps 1.43M DS 1.52M"}, {"zfsfs": "zroot/homes/toms", "zfsfsval": "Used 573G Snaps 25.4G DS 261G"}, {"zfsfs": "zroot/homes/toms/Games", "zfsfsval": "Used 287G Snaps 32.7M DS 287G"},

The config stanza:

      {
        "type": "command",
        "text": "/home/toms/bin/fastfetch-zfs.sh",
        "key": "{#90}│ {#91}ZFS DS      {#90}│",
        "format": "{$1}{zfsfs} {zfsfsval}"
      },

You are creating features.

You use bash script. You format it in bash.

So it is not possible to format and display multiple lines of output using the command module? If I wish to format and display multiple zfs datasets I need to have a separate command stanza for each one?
