Manage configuration values. Only config set persists values to the config file.

spidal config list                   # show all current values and sources
spidal config get <key>              # show a single value and its source
spidal config set <key> <value>      # persist a value to the config file

Examples:

spidal config get audio-quality
spidal config set download-dir ~/Music/flac
spidal config set audio-quality LOSSLESS
spidal config set download-delay 3
spidal config set spotify-token <token>
spidal config set hifi-api https://my-instance.example.com

spidal where db        # open database directory

Configuration

Options can be set via spidal config set, environment variables, or CLI flags. Only spidal config set persists values across sessions — CLI flags and environment variables are applied at runtime only.

Priority: CLI flags > config file > environment variables > defaults

Config file: ~/.config/spidal/config.json

Key	CLI flag	Env var	Default	Description
spotify-token	--spotify-token	SPIDAL_SPOTIFY_TOKEN	—	Spotify access token

hifi-api-file	--hifi-api-file	SPIDAL_HIFI_API_FILE	monochrome instances URL	URL or path to JSON file with API list
download-dir	--download-dir	SPIDAL_DOWNLOAD_DIR	~/Music/spidal	Download directory

Audio quality

LOSSLESS	16-bit/44.1kHz FLAC
HIGH	320kbps AAC

Tagging

Downloaded tracks are automatically tagged using the MusicBrainz API (via ISRC lookup). No API key is required. Tagging can be disabled with spidal config set disable-tagging true.

The actual file format is detected from magic bytes after download and the file is renamed accordingly (e.g. DASH streams produce .m4a, not .flac). Tags are written using the appropriate format:

Format	Container	Tag standard
.flac	FLAC	VorbisComment
.m4a	MPEG-4	iTunes (MP4)
.ogg	Ogg	VorbisComment (Vorbis or Opus)

Tags written per track:

Tag	Source
TITLE	Monochrome API
ARTIST	Monochrome API
ALBUM	Monochrome API / Spotify
TRACKNUMBER	Monochrome API
ISRC	Monochrome API
DATE	MusicBrainz release
GENRE	MusicBrainz tag list
ALBUMARTIST	MusicBrainz artist credit
DISCNUMBER	MusicBrainz release medium
DISCTOTAL	MusicBrainz release medium
TRACKTOTAL	MusicBrainz release medium
MUSICBRAINZ_TRACKID	MusicBrainz recording MBID
MUSICBRAINZ_ALBUMID	MusicBrainz release MBID
MUSICBRAINZ_ARTISTID	MusicBrainz artist MBID

Tag names follow MusicBrainz Picard conventions and are compatible with Plex, Roon, and other media servers.

Tagging is best-effort — failures are logged but never interrupt the download.
