    <p>Cool idea. Here's a start that works for me: just need to change a few lines in <code>dired-compress-file</code>. I've highlighted the changes with <code>BEGIN EDIT</code> and <code>END EDIT</code> comments (sorry if there's a better way to highlight a diff). I'm sure this isn't robust, but maybe it can point you in the right direction.</p> <p>EDIT: I should say that the below works for me in GNU Emacs 24.3.1.</p> <pre><code>(defun dired-compress-file (file) ;; Compress or uncompress FILE. ;; Return the name of the compressed or uncompressed file. ;; Return nil if no change in files. (let ((handler (find-file-name-handler file 'dired-compress-file)) suffix newname (suffixes dired-compress-file-suffixes)) ;; See if any suffix rule matches this file name. (while suffixes (let (case-fold-search) (if (string-match (car (car suffixes)) file) (setq suffix (car suffixes) suffixes nil)) (setq suffixes (cdr suffixes)))) ;; If so, compute desired new name. (if suffix (setq newname (concat (substring file 0 (match-beginning 0)) (nth 1 suffix)))) (cond (handler (funcall handler 'dired-compress-file file)) ((file-symlink-p file) nil) ((and suffix (nth 2 suffix)) ;; We found an uncompression rule. (if (not (dired-check-process (concat "Uncompressing " file) (nth 2 suffix) file)) newname)) (t ;;; We don't recognize the file as compressed, so compress it. ;;; Try gzip; if we don't have that, use compress. (condition-case nil ;; BEGIN EDIT - choose the correct name if looking at a directory (let ((out-name (if (file-directory-p file) (concat file ".tar.gz") (concat file ".gz")))) ;; END EDIT (and (or (not (file-exists-p out-name)) (y-or-n-p (format "File %s already exists. Really compress? " out-name))) ;; BEGIN EDIT: create a tarball if we're looking at a directory (not (if (file-directory-p file) (dired-check-process (concat "Compressing " file) "tar" "-zcf" out-name file) (dired-check-process (concat "Compressing " file) "gzip" "-f" file))) ;; END EDIT (or (file-exists-p out-name) (setq out-name (concat file ".z"))) ;; Rename the compressed file to NEWNAME ;; if it hasn't got that name already. (if (and newname (not (equal newname out-name))) (progn (rename-file out-name newname t) newname) out-name))) (file-error (if (not (dired-check-process (concat "Compressing " file) "compress" "-f" file)) ;; Don't use NEWNAME with `compress'. (concat file ".Z")))))))) </code></pre>

    1. COIt looks cool, but I'm looking for a one-line solution. Brevity would make it easy to confirm it is correct. Just like one receives suggestions for variations of gunzip when one presses '!' on a compressed file or compressed archive, it would be ideal to offer the suggestion to run "tar -zcf dirname.tgz dirname" when one presses 'Z' in dired-more on a directory dirname.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
