"""
tool which runs over a complete music library (or audiobooks, videos, ebooks (limited)) or a subset of it and:
- fixes missing or incorrect tags:
- suggests likely tags based on file path
- from correctly-tagged files in the same directory
- or manually specified by the user
- rewrites file paths based on tags (`AlbumArtist/AlbumTitle/TrackNumber-TrackTitle`)
- resulting paths are exclusively `[a-zA-Z0-9\._-]`
- characters outside this set are mapped to the nearest character. for example:
- `&` is replaced by `And`
- `ü` is replaced by `u`
- `百合` is replaced by `Yuri` (pykakasi is used for romanization)
- ` ` is replaced by `.`
- albums released under an alias are given a path as follows, if tagged correctly:
- `Producer/AlbumArtist-AlbumTitle/TrackNumber-TrackTitle`
- for example, "HALLEY LABS" released an album under the alias of "BANDETTO":
- the paths are like: `HALLEY.LABS/BANDETTO-WAV.SLAVE/01-bouncy.castle.boogie.flac`
- tagged with `--producer "HALLEY LABS" --album-artist "BANDETTO" --album ".WAV SLAVE"`
USAGE: cd MEDIA_LIBRARY_TOP && sane-tag-media [options] fix-paths|fix-tags|show-missing|show [cmd-specific options] DIRECTORY [DIRECTORY ...]
DIRECTORY: specify `.` to scan the entire library.
use relative paths here, like `SomeArtist` or `./SomeArtist/SomeAlbum`, so that it can better extract metadata fields from the paths.
options:
--dry-run: only show what would be done, don't actually do it.
--verbose
--derive apply existing tags (e.g. album) found in the file set to any files in the set missing such tags.
additionally, extrapolate from the file path any missing tags.
--ignore-existing completely ignore the existing on-disk tags. compute tags only from those manually provided, and what can be derived from the file path (if --derive was passed)
--override-existing apply derived tags to each file, even those which already have tags.
only makes sense when paired with --derive.
--type audio|image|text skip files which aren't of some specific media type
manually writing metadata fields:
--album ALBUM
--album-artist ARTIST often combined with DIRECTORY to tag an entire artist or album.
--artist ARTIST track artist; usually the same as album-artist, except for compilation albums.
--producer PRODUCER use when the artist is a pseudonym, and this is their umbrella name.
--title TITLE
--trackno TRACK_NUMBER

tool which runs over a complete music library (or audiobooks, videos, ebooks (limited)) or a subset of it and:
- detect tags which are missing or likely incorrect
- write new tags to existing media
- new tags are specified manually (--artist, --album, ...)
- OR determined via file path
this tool does NOT move or rename files. it only edits tags.
USAGE: cd MEDIA_LIBRARY_TOP && sane-tag-media [options] fix-paths|fix-tags|show-missing|show [cmd-specific options] DIRECTORY [DIRECTORY ...]
scans DIRECTORY and guesses artist/album/title for each file, based on path relative to pwd.
if the guessed tags look more correct than the existing tags (i.e. if the existing file is missing a tag),
then this updates the tags on-disk to reflect their path.
DIRECTORY: specify `.` to scan the entire library.
options:
--dry-run: only show what would be done, don't actually do it.
--verbose
--album ALBUM manually specify the tag, rather than guessing from path.
--album-artist ARTIST often combined with DIRECTORY to tag an entire artist or album.
--artist ARTIST
--producer PRODUCER use when the artist is a pseudonym, and this is their umbrella name.
