mack |

mack is an opinionated, fast music organiser. It enforces:

• Directory layout
• File name format
• Metadata consistency (e.g., consistent "feat" tagging)
• Format consistency (e.g., ID3 version)
• ...and more!

Examples of fixes

• Moving featured artists from the artist tag to the title
• Enforcing a consistent "feat" format in title tags
• Whitespace normalisation
• Renaming files to format "{artist}/{album}/{track} {title}", or another format specified with --fmt

Usage

See --help. An example invocation is:

% mack --dry-run -o Music .
01 Pyramid.mp3: renamed to Music/宇宙コンビニ/染まる音を確認したら/01 Pyramid.mp3
02 8films.mp3: renamed to Music/宇宙コンビニ/染まる音を確認したら/02 8films.mp3
03 tobira.mp3: renamed to Music/宇宙コンビニ/染まる音を確認したら/03 tobira.mp3
04 Compass.mp3: renamed to Music/宇宙コンビニ/染まる音を確認したら/04 Compass.mp3
05 strings.mp3: renamed to Music/宇宙コンビニ/染まる音を確認したら/05 strings.mp3

You can see what would be changed first using --dry-run.

Installation

cargo install mack

Performance

mack has a strong focus on performance. Files which were not updated since the last mack run will not be examined at all. On a sample modern laptop with a mid-spec SSD, this means that we only take 0.005 seconds to run over ~3500 files under most circumstances (0.015 seconds on the very first run).

Configuration

If you don't want a particular file to be touched by mack, add _NO_MACK as a substring anywhere in the comment tag.
