Create an empty file with the following code:
Example 1. A Simple Extension
from gi.repository import Nautilus, GObject
class ColumnExtension(GObject.GObject, Nautilus.MenuProvider):
def __init__(self):
pass
def menu_activate_cb(self, menu, file):
print "menu_activate_cb",file
def get_file_items(self, window, files):
if len(files) != 1:
return
file = files[0]
item = Nautilus.MenuItem(
name="SimpleMenuExtension::Show_File_Name",
label="Showing %s" % file.get_name(),
tip="Showing %s" % file.get_name()
)
item.connect('activate', self.menu_activate_cb, file)
return [item]
# Even though we're not using background items, Nautilus will generate
# a warning if the method isn't present
def get_background_items(self, window, file):
return NoneSave this file as TestExtension.py in the ~/.local/share/nautilus-python/extensions folder. You may need to create this folder. To run, simply restart Nautilus.
Once Nautilus restarts, right-click on a file and you should see a new menu item, "Showing #filename#". It is as simple as that!
As mentioned above, in order to get loaded by Nautilus, a python extension must import the Nautilus module from gi.repository, create a class derived from a nautilus *Provider and a gobject.GObject, and create the methods that will be called by Nautilus when it requests information from its providers. In this case, when someone right-clicks on a file, Nautilus will ask all of its MenuProviders for additional menu items to show the user. When folders or files are clicked, the get_file_items method is called and a list of Nautilus.MenuItems is expected.
