An integration between GNU Emacs and TMSU.

tmsu.el doesn't try to replicate the full functionality of TMSU. Instead it focuses on enhancing the UX of the most common operations: tag editing and querying. It's primarily intended to be used from dired, though tmsu-edit can be used separately from it.

The two main commands are tmsu-dired-edit to interactively edit the tag list of the currently selected file and tmsu-dired-query to create a dired buffer with the TMSU query results. Both utilize the Emacs completing-read-multiple interface and so greatly benefit from packages such as vertico.

The queries can be stored for later recall either with the native Emacs bookmarks or with org-mode links using org-store-link.

The first type is supported out of the box. The second one needs to be loaded:

(require 'ol-tmsu)

tmsu-dired-tags-add and tmsu-dired-tags-remove can be used to edit tags of multiple files at a time. For convenience, the completion of tmsu-dired-tags-remove offers the sum of tags of all the marked files.

To install tmsu.el, you can use the following code:

(use-package tmsu
  :ensure t
  :after dired
  :bind (:map dired-mode-map
         (";" . tmsu-dired-edit)
         ("M-;" . tmsu-dired-query)
         ("C-M-;". tmsu-dired-overlay))
  :config (require 'tmsu-dired))

If you prefer to attach your TMSU tags to directories and not single files (think: a directory with a set of movies with common tags), use tmsu-dired-edit-directory instead of tmsu-dired-edit. See their docstrings for the details.

For the org-mode links support, this is the suggested setup:

(use-package ol-tmsu
  :ensure t
  :after (:any org tmsu-dired)
  :if (executable-find "tmsu"))

Orderless compatibility

If you're using Orderless with a style dispatcher using = as a suffix (which is the default since early 2023 when orderless-affix-dispatch got added), you may want to add the following snippet:

(defun call-without-orderless-dispatchers (orig &rest args)
  "Use with `advice-add' (`:around') to ignore the dispatchers."
  (let ((orderless-style-dispatchers nil))
    (apply orig args)))

(advice-add 'tmsu-edit :around
            #'call-without-orderless-dispatchers)
(advice-add 'tmsu-dired-query :around
            #'call-without-orderless-dispatchers)

This modification allows the completion suggestions for inputs like tag= to show up immediately and not only after the next keypress (that makes the input not end with = anymore).
