Adding PUSHOVER priority and sound options for zed.rc to be used in zed_notify_pushover() function

[TechLoom]

Add variables to zed.rc file (example of changing to high prority and longer notification sound.

ZED_PUSHOVER_PRIORITY="1"
ZED_PUSHOVER_SOUND="alien"

Edit the function in zed-functions.sh

If options are not set in zed.rc then default back to normal prority and defualt notification sound.

zed_notify_pushover()
{
    local subject="$1"
    local pathname="${2:-"/dev/null"}"
    local msg_body
    local msg_out
    local msg_err
    local url="https://api.pushover.net/1/messages.json"

    # --- NEW: Default values for priority and sound ---
    # These are used if ZED_PUSHOVER_PRIORITY or ZED_PUSHOVER_SOUND are not set in zed.rc
    local DEFAULT_PRIORITY="0"   # Default to normal priority
    local DEFAULT_SOUND="pushover" # Default Pushover sound

    # --- NEW: Determine final priority and sound to use ---
    # Use ZED_PUSHOVER_PRIORITY if it's set and not empty, otherwise use DEFAULT_PRIORITY
    local final_priority="${ZED_PUSHOVER_PRIORITY:-${DEFAULT_PRIORITY}}"
    # Use ZED_PUSHOVER_SOUND if it's set and not empty, otherwise use DEFAULT_SOUND
    local final_sound="${ZED_PUSHOVER_SOUND:-${DEFAULT_SOUND}}"

    [ -n "${ZED_PUSHOVER_TOKEN}" ] && [ -n "${ZED_PUSHOVER_USER}" ] || return 2

    if [ ! -r "${pathname}" ]; then
        zed_log_err "pushover cannot read \"${pathname}\""
        return 1
    fi

    zed_check_cmd "curl" "sed" || return 1

    # Read the message body in.
    #
    msg_body="$(cat "${pathname}")"

    if [ -z "${msg_body}" ]
    then
        msg_body=$subject
        subject=""
    fi

    # Send the POST request and check for errors.
    #
    msg_out="$( \

        )"; rv=$?
    if [ "${rv}" -ne 0 ]; then
        zed_log_err "curl exit=${rv}"
        return 1
    fi
    msg_err="$(echo "${msg_out}" \
        | sed -n -e 's/.*"errors" *:.*\[\(.*\)\].*/\1/p')"
    if [ -n "${msg_err}" ]; then
        zed_log_err "pushover \"${msg_err}"\"
        return 1
    fi
    return 0
}
