;; My configurations of the wonderful Tramp.

;;; Code:

(require 'tramp)

;;; Fix a Tramp copy arg

(cond
 ((assoc "rsync" tramp-methods #'equal)
  (setcar
   (cdr
    (assoc
     'tramp-copy-args
     (assoc "rsync" tramp-methods #'equal)))
   (list
    (list "-t" "%k")
    (list "-p")
    (list "-r")
    ;; this option is invalid for my rsync program, for some reason
    ;; ("-s")
    (list "-c")))))

;;; Disable backups for Tramp

(add-to-list 'backup-directory-alist (cons tramp-file-name-regexp nil))

;;; Don't ask this over and over.

(setq tramp-allow-unsafe-temporary-files t)

;;; Disable version control on remote hosts

(setq
 vc-ignore-dir-regexp
 (format "\\(%s\\)\\|\\(%s\\)"
         vc-ignore-dir-regexp tramp-file-name-regexp))

(provide 'tramp-conf)
;;; tramp-conf.el ends here
