Although I’m using emacs dired as my default file manager, I don’t like any of the terminal emulators in Emacs at all. I usually use a separate application for working with shell command (iTerm on Mac). The problem is that when I’m browsing my files in Emacs and I want to open terminal for doing shell commands in the current directory, I have to copy the path of the current directory, open terminal and type cd to that folder.

I’ve written a small function to help me quickly open a new terminal window at the current directory that I’m browsing in Emacs (MacOS only).

;; default terminal application path
(defvar tmtxt/macos-default-terminal-app-path
	"/Applications/" "The default path to terminal application in MacOS")
;;; function to open new terminal window at current directory
  (defun tmtxt/open-current-dir-in-terminal ()
	"Open current directory in dired mode in terminal application.
For MacOS only"

	(shell-command (concat "open -a "
						   (shell-quote-argument tmtxt/macos-default-terminal-app-path)
						   " "
						   (shell-quote-argument (file-truename default-directory)))))

When you want to use the function, you need to set the variable tmtxt/macos-default-terminal-app-path to the absolute path to your terminal application if you’re not using MacOS’s default terminal application.

(setq-default tmtxt/macos-default-terminal-app-path "/Volumes/tmtxt/Applications/")

Finally, bind it to a keystroke that you want, for example

(define-key dired-mode-map (kbd "C-c C-o") 'tmtxt/open-current-dir-in-terminal)

Now in any dired buffer, just type C-c C-o, the terminal application that you specified before will open and automatically cd to the current directory. In any other buffer types, you can still activate this function by using M-x, the terminal application will open with the directory that contain the file you’re currently editing.
