Configuring Thunderbird As KNotes Mail Action

The steps are really simple.

1. Save the below script to /usr/local/bin/knotes-mail-wrapper.sh

   #!/bin/bash
   
   set -eu
   
   # See /usr/share/doc/util-linux/examples/getopt-parse.bash for getopt example
   TEMP=$(getopt --name "$0" --options s:,b: --longoptions "subject:,body:" -- "$@")
   
   # Bad arguments, something has gone wrong with the getopt command.
   if [ $? -ne 0 ]; then
     echo "Termintaing ..." >&2
     exit 1
   fi
   
   # Note the quotes around `$TEMP': they are essential!
   eval set -- "$TEMP"
   
   # Now go through all the options
   while true; do
     case "$1" in
       --subject)
         subject=$2
         shift 2;;
   
       --body)
         body=$2
         shift 2;;
   
       --)
         shift
         break;;
   
       *)
         echo "Error parsing arguments" >&2
         exit 1;;
     esac
   done
   
   thunderbird_command=$(command -v icedove >/dev/null 2>&1 && echo icedove || echo thunderbird)
   $thunderbird_command -compose "subject='$subject',body='$body'"

2. Make the script executable.
   

   $ chmod +x /usr/local/bin/knotes-mail-wrapper.sh
   

3. Go to Configure Knotes... -> Actions and in mail action set it to "/usr/local/bin/knotes-mail-wrapper.sh --subject %t --body %f".

Now whenever you right click on a note toolbar and click on Mail..., thunderbird compose window should pop-up with the subject as the note title and body as the content of the note.
