In Emacs, how do I use directory local variables for remote projects?
I'm using TRAMP to connect to a remote server and I wanted to use some directory local variables. What are my options? Should I use emacs-server and do it that way, or should I add the directory local variables to my .emacs file? Is there a way to force T开发者_如何学运维RAMP to look for the .dir-locals.el file?
If you're using Emacs 24.3 or later, set enable-remote-dir-locals
to t.
For Emacs 24.3 or later, see legoscia's answer.
For earlier versions, you can use the following workaround from EmacsWiki:
We can advise
‘hack-dir-local-variables’
to work around this, if you are willing to incur the associated performance cost (which can be relatively minimal in some situations).;; Enable directory local variables with remote files. This facilitates both ;; the (dir-locals-set-class-variables ...)(dir-locals-set-directory-class ...) ;; and the .dir-locals.el approaches. (defadvice hack-dir-local-variables (around my-remote-dir-local-variables) "Allow directory local variables with remote files, by temporarily redefining `file-remote-p' to return nil unconditionally." (flet ((file-remote-p (&rest) nil)) ad-do-it)) (ad-activate 'hack-dir-local-variables)
If using directory classes instead of a .dir-locals.el
file, you would set the class using a normal tramp path. e.g.:
(dir-locals-set-class-variables
'read-only
'((nil . ((buffer-read-only . t)))))
(dir-locals-set-directory-class
"/ssh:(user)@(host):/path/to/dir" 'read-only)
