Add after-save-hook to a mode

Add after-save-hook to a mode

[Florian Lindner]

Hello,

I want to org-mobile-push executed everytime a file in org-mode is
saved. I tried that:

(add-hook 'org-mode-hook
	  (add-hook 'after-save-hook
		    (lambda ()
		      (org-mobile-push)
		      )))

This seems to war, but the hook is executed regardless of the mode the
file is in. How can I restrict it to org-mode only?

Thanks,

Florian

(add-hook 'after-save-hook
	  (lambda ()
	    (when (string= mode-name "Org")
	      (org-mobile-push))))

Your code modifies `after-save-hook', which is a global variable, every
time `org-mode-hook' is run.
`add-hook' also allows to modify hooks buffer-locally. From its
docstring:

You can use this to change the value of `after-save-hook' only in those
buffers that run the `org-mode-hook'. This should do:


(add-hook
 'org-mode-hook
 (lambda nil
   (add-hook 'after-save-hook
             (lambda nil (org-mobile-push))
             nil 'local))) ;Only in the current buffer
