A CLI audio tag editor and processor written in Python 3.x using the mutagen module, with support for regular expressions and autonumbering. It's more intended for batch processing tags.

It can be installed through pip:

$ pip install git+https://codeberg.org/monego/clitag.git

Set some tags for all audio files in a folder:

$ clitag --artist "Someone" --album "Something" afolder/*.opus

Delete a tag:

$ clitag --delete "genre" -- afolder/*.opus

Use a regular expression to replace something in a tag:

$ clitag --re-title "regexp" "replacement" afolder/*.opus

Autonumber an album:

$ clitag --autonumber afolder/*.opus

Autotitle based on filename. Give it a start, end, and a separator. For e.g. "[tracknumber] - Title - [Date]" use:

$ clitag --autotitle 2 -2 --sep " " afolder/*.opus

or

$ clitag --autotitle 1 -1 --sep "-" afolder/*.opus

. The title has to have the same separator at both ends.

The two dependencies are mutagen and rich.
