# Function: mus
# Purpose : Retrieve and display the currently playing song from MPD,
#           trimming it to a maximum of 50 characters (with ellipsis)
#           if the total length exceeds 30 characters.
# Inputs  : None
# Outputs : Echoes a trimmed or full song title depending on length.

mus() {
    # Fetch the current song details in format "Artist - Title" or just "Title"
    current_song=$(mpc current -f "[[%artist% - ]%title%]")

    # Calculate the title length
    size=${#current_song}

    # Define thresholds
    local max_length=50       # Maximum characters to show including truncation
    local display_length=30   # When to start truncating

    if [ "$size" -gt "$display_length" ]; then
        # Truncate and append ellipsis
        echo "${current_song:0:$max_length}..."
        # echo "${current_song:0:$max_length}..." > currentsong.txt  # Write to file instead of echoing
    else
        # Print full title
        echo "$current_song"
        # echo "$current_song" > currentsong.txt  # Write to file instead of echoing
    fi
