# Example config for the MusicMouse backend.

# Keep the real config (with credentials) off the repo - on the device only.

general:
  # The music collection. One path; the shelves underneath it are fixed names, not
  # settings, because each one has its own quirks the code already knows about:
  #
  #   <root>/Figuren/<figure name>/          one folder per figurine
  #   <root>/Musik/<Artist> - <Album>/       albums, grouped by artist
  #   <root>/Hörbücher/<Artist> - <Album>/   audiobooks, grouped by character
  #   <root>/Kinderpodcasts/<Show>/          shows, newest episode first
  #
  # A cover.jpg next to the audio is used if present, otherwise the art is pulled out
  # of the files' tags. Relative paths resolve against this file's directory.
  library:
    root: /home/martin/Music
    # Scan results, extracted cover art and track analysis. Safe to delete: the index
    # is rebuilt on the next start. Deleting it does throw away track analysis, which
    # is expensive to recompute.
    cache: .musicmouse-cache
    # How many tracks the background analyzer may work on at once, each in its own
    # worker process. Omitted means one per core bar one (capped at 8), which is what
    # turns a first-time pass over a whole library from an overnight job into a coffee
    # break on a desktop. Set it to 1 on a machine that has better things to do, or to
    # a specific number to cap how much of it analysis may take.

  # Serial port the ESP32 firmware is on. A dropped link is retried, not fatal.

  # commandeer. Startup says so every boot.
