When opening a file that is not writable by the current user, jEdit should check whether
the user wants to open the file read-only or as superuser / another user. Here's an
imagined workflow:
1. According to the principle of least privilege, start by notifying the user that
the file cannot be modified with the current privileges. Ask if the user wants to
open read-only or read-write (and maybe a check box to use the same option for all
other files opened at the same time).
2. If the user selected read-write, display the users/groups which have write access
and user/password boxes. If the user is also a member of sudoers, there could be a
check box to use sudo which would gray out the user box and focus the password.

Hi, I'm not sure it is possible to do that with java.

It would have to be adopted to the individual platforms, but certainly it should be possible in Java. There should be cross-platform libraries at least to get the privileges assigned to a file. Emacs does this <http://stackoverflow.com/questions/95631/open-a-file-with-su-sudo-inside-emacs>, and Vim at least allows you to save via sudo <http://www.commandlinefu.com/commands/view/1204/save-a-file-you-edited-in-vim-without-the-needed-permissions>. Nautilus and Explorer both have options to run as superuser, so it should be possible to find the code that does just the access right reading. |

For windows, you need to start Java already in escalated mode and then jEdit has permissions
too. I don't know how to do it to a Java process while it is running.
