Open a filer window showing a file I'm editing

There are various possibilities:

• ROX-style applications like Edit should already have an Up button on their toolbar for this.

• You can get some window managers to provide such a button in the title bar. This code creates a change-to-parent action for sawfish:

  (defun change-to-parent (window)
    "Close window and open the parent directory viewer"
    (interactive "%W")
    (let ((title (caddr (get-x-property window 'WM_NAME))))
      (when (and title (string-match "[~/][^*?]+" title))
        (let ((path (substring title (match-start 0) (match-end 0))))
          (system (concat "rox -s " path))
          (delete-window-safely window)
  ))))

• You can script other applications. For example, Stephen Watson gives these instructions for Emacs:

  (defun rox-view-file (file)
    "Open ROX-Filer window for named file"
    (interactive "fFile to show: ")
    (call-process "rox" nil 0 nil "-s" file)
    )
  (defun rox-view-current ()
    "Open ROX-Filer window for the current file"
    (interactive)
    (rox-view-file buffer-file-name)
    )

• For Vim (or GVim), put this in your ~/.vimrc file:

    map <F12> :silent !rox -s %<CR>
