Creating and managing playlists, and managing the filenames and directory structure for large numbers of music files.

Media Tools

Toolbox for helping creating and managing playlists, and managing the filenames and directory structure for large numbers of music files.

This is mostly tailored to my own usage patterns, although it may be useful to others.

Installation

$ pip install media-tools

Usage

In general: run a script with the -v option first to see what it would change. If satisfied, then re-run it with the -f option to effect those changes.

clean_filenames

Removing useless duplicate strings from filenames:

$ clean_filenames.py -v clean-filenames --recurse .
$ clean_filenames.py -f clean-filenames --recurse .

Changing filenames from different numbering schemes to the scheme 01 - filename.ext:

$ clean_filenames -v clean-numbering .
$ clean_filenames -f clean-numbering .

Removing stray junk, such as underscores, stray dashes, and stray [] and () from filenames:

$ clean_filenames -v clean-junk .
$ clean_filenames -f clean-junk .

Undoing renamings done with this script, limited to a specified directory and its subfolders, or a single file name:

$ clean_filenames -v undo .
$ clean_filenames -f undo .
# OR
$ clean_filenames -f undo ./subdir/file_name.mp3

Fixing symlinks to files which have been renamed by any of the previous commands:

$ clean_filenames -v fix-symlinks .
$ clean_filenames -f fix-symlinks .

Checking results

Finding mp3 files which do not conform to the numbering scheme in general:

$ find . -name \*.mp3 | grep -vE '[[:digit:]]+ - .+\.mp3'

Finding mp3 files which have a number in their filename but do not conform to the numbering scheme, excluding some more common use cases:

$ find . -name \*.mp3 | \
    grep -E '[[:digit:]]+[^/]+\.mp3' | \
    grep -vE '[[:digit:]]+ - .+\.mp3' | \
    grep -vE '[[:digit:]]{2}\.mp3'

Audacious playlist tools

Tools for making and repairing playlists containing physical music files from audacious playlists and the latest music files. The argument to --playlist defaults to the playlist currently playing in audacious.

copy_from_playlist

Copying files from the current or specified playlist (as its name in the playlists subdir in the audacious configuration folder) to a specified target folder, optionally limiting the number of files to copy to the first NUM, and optionally renaming the files to reflect the position of the song in the playlist:

$ copy_from_playlist [-v] copy \
    [--playlist PLAYLIST_ID] \
    [--number NUM] \
    [--renumber] \
    TARGET_DIR

Try to find files in the current playlist which are unavailable because they have been moved, and move them back to the place in the filesystem which is noted on the playlist (does not appear to work currently):

$ copy_from_playlist [-v] restore \
    [--playlist PLAYLIST_ID]

Copy the newest files to a specified target:

$ copy_from_playlist [-v] copy-newest \
    --max-age NUM_DAYS \
    --source SOURCE_DIR \
    --target TARGET_DIR

mixcloud_upload

Development

After cloning, it is recommended to set up the git hook that runs the test suite before every git push:

$ cd .git/hooks
$ ln -s ../../.git_hooks/pre-push .

Test suite

$ .git_hooks/pre-push

TO DO

• fix broken symlinks
  • finding broken symlinks: $ find DIR -type l -follow -exec readlink -f "{}" \;
• fix audacious playlists which contain moved songs
• fix filenames with common encoder suffixes
• make extensions all lowercase
• migrate undo database to JSON (backup old db first :-/)
