Sincronise eshell directory to file

Sincronise eshell directory to file

[Lorenzo Isella]

Dear All,
My typical working pattern in emacs is to have an eshell + a buffer
(showing one of the program I intend to modify).
I switch between several of these code buffers and it would be very
useful for me to automatically change directory (within eshell) to the
one corresponding to the file I am visiting though the buffer.
Does anyone know how this can be achieved?
Cheers

Lorenzo

You can probably hack something like a custom command that you would
call from your current buffer. It would read `default-directory, then
take you to your eshell buffer and issue a `cd the_default-directory'.

Could you imagine running N *eshell* buffers? Then you won't have to  
change directories ...

Well, if possible I would like to avoid the proliferation of buffers,
unless it is necessary.

Here is a basic solution which uses `window-configuration-change-hook'.
What's left is getting eshell to play along, change the prompt and
handle partial input for example.

(defun eshell-follow-dir-hook nil
   (when (not (eq major-mode 'eshell-mode))
     (let ((pwd default-directory))
       (walk-windows #'(lambda (win)
			(with-selected-window win
			  (when (and (eq major-mode 'eshell-mode)
				     (not (equal pwd default-directory)))
			    (cd pwd))))
		    'no-minibuffer))))

(add-hook 'window-configuration-change-hook 'eshell-follow-dir-hook)
