Additional Directory Sources

Directories visited in eshell

Here is a command to quickly switch directories in eshell that piggybacks on consult-dir:

2021-10-08-165543_960x588_scrot Demo

It combines the existing consult-dir sources with eshell's cd history.

(defun eshell/z (&optional regexp)
  "Navigate to a previously visited directory in eshell."
  (let ((eshell-dirs (delete-dups (mapcar 'abbreviate-file-name
                                          (ring-elements eshell-last-dir-ring)))))
    (cond
     ((and (not regexp) (featurep 'consult-dir))
      (let* ((consult-dir--source-eshell `(:name "Eshell"
                                                 :narrow ?e
                                                 :category file
                                                 :face consult-file
                                                 :items ,eshell-dirs))
             (consult-dir-sources (cons consult-dir--source-eshell consult-dir-sources)))
        (eshell/cd (substring-no-properties (consult-dir--pick "Switch directory: ")))))
     (t (eshell/cd (if regexp (eshell-find-previous-directory regexp)
                     (completing-read "cd: " eshell-dirs)))))))

Docker containers using TRAMP

Requires the docker-tramp package.

(defun consult-dir--tramp-docker-hosts ()
  "Get a list of hosts from docker."
  (when (require 'docker-tramp nil t)
    (let ((hosts)
          (docker-tramp-use-names t))
      (dolist (cand (docker-tramp--parse-running-containers))
        (let ((user (unless (string-empty-p (car cand))
                        (concat (car cand) "@")))
              (host (car (cdr cand))))
          (push (concat "/docker:" user host ":/") hosts)))
      hosts)))

(defvar consult-dir--source-tramp-docker
  `(:name     "Docker"
    :narrow   ?d
    :category file
    :face     consult-file
    :history  file-name-history
    :items    ,#'consult-dir--tramp-docker-hosts)
  "Docker candiadate source for `consult-dir'.")

;; Adding to the list of consult-dir sources
(add-to-list 'consult-dir-sources 'consult-dir--source-tramp-docker t)

Directories visited in the shell using FASD

Requires fasd to be available in your shell environment.

;; A function that returns a list of directories
(defun consult-dir--fasd-dirs ()
  "Return list of fasd dirs."
  (split-string (shell-command-to-string "fasd -ld") "\n" t))

;; A consult source that calls this function
(defvar consult-dir--source-fasd
 `(:name     "Fasd dirs"
   :narrow   ?f
   :category file
   :face     consult-file
   :history  file-name-history
   :enabled  ,(lambda () (executable-find "fasd"))
   :items    ,#'consult-dir--fasd-dirs)
  "Fasd directory source for `consult-dir'.")

;; Adding to the list of consult-dir sources
(add-to-list 'consult-dir-sources 'consult-dir--source-fasd t)
