Edit files from within Trac
This is a plugin that allows Trac administrators (TRAC_ADMIN) to edit files on the Trac server. The editable files can be specified in the configuration file. Paths may be absolute, or relative to the Trac environment. The user running the server must have appropriate permissions for the files in order to view or save them.
Sample trac.ini file with the editable files listed in the custom [edit_file] section:
[edit_file] files = conf/trac.ini, /home/matt/public_html/notebook/TRACI/auth.db
Note: Relative paths will be computed relative to the location of trac.ini. Most Trac instances are laid out with folders like conf/, db/, htdocs/ and so on. If your trac.ini file is in an odd place, this may not work the way you expect and you might want to use absolute paths instead.
If you have any issues, create a new ticket.
