Hi,
I am learning to write scripts for nautilus-python and, after reading the
docs and some examples, I elaborated this small script:
#!/usr/bin/env python
from gi.repository import Nautilus, GObject, Gtk, GdkPixbuf
import urllib, os, subprocess, re
import locale, gettext
ROOT_ICON = "/usr/share/icons/elementary/stock/48/stock_person.svg"
TERMINAL_ICON = "/usr/share/pixmaps/gksu-root-terminal.png"
NAUTILUS_ICON = "/usr/share/icons/hicolor/scalable/apps/nautilus.svg"
class ColumnExtension(GObject.GObject, Nautilus.MenuProvider):
def __init__(self):
try:
factory = Gtk.IconFactory()
# Add Root icon
pixbuf = GdkPixbuf.Pixbuf.new_from_file(ROOT_ICON)
iconset = Gtk.IconSet.new_from_pixbuf(pixbuf)
factory.add("Root", iconset)
# Add Nautilus icon
pixbuf = GdkPixbuf.Pixbuf.new_from_file(NAUTILUS_ICON)
iconset = Gtk.IconSet.new_from_pixbuf(pixbuf)
factory.add("Nautilus", iconset)
# Add Root Terminal icon
pixbuf = GdkPixbuf.Pixbuf.new_from_file(TERMINAL_ICON)
iconset = Gtk.IconSet.new_from_pixbuf(pixbuf)
factory.add("Terminal", iconset)
factory.add_default()
except: pass
def root_terminal(self, menu, selected):
"""Runs the Terminal on the given Directory"""
bash_string = "gksu \"exo-open --launch TerminalEmulator
--working-directory='" + selected + "'\" &"
subprocess.call(bash_string, shell=True)
def open_with_nautilus(self, menu, selected):
"""Open the selected Folder with Nautilus as Root User"""
subprocess.call("gksu \"nautilus --no-desktop " + selected + "\"
&", shell=True)
def get_background_items(self, window, current_directory):
menuitem = Nautilus.MenuItem(name='RootMenu::Root',
label='Root',
tip='',
icon='Root')
submenu = Nautilus.Menu()
menuitem.set_submenu(submenu)
sub_menuitem = Nautilus.MenuItem(name='RootMenu::RootTerminal',
label='Root Terminal',
tip='',
icon='Terminal')
submenu.append_item(sub_menuitem)
sub_menuitem.connect('activate', self.root_terminal,
re.escape(current_directory))
sub_menuitem = Nautilus.MenuItem(name='RootMenu::OpenNautilus',
label='Open as Root',
tip='',
icon='Nautilus')
submenu.append_item(sub_menuitem)
sub_menuitem.connect('activate', self.run_as_root,
re.escape(current_directory))
return menuitem,
Unfortunately, Nautilus does not like these lines and spits out an error:
Traceback (most recent call last):
File "/home/vigil/.local/share/nautilus-python/extensions/root-menu.py",
line 63, in get_background_items
sub_menuitem.connect('activate', self.root_terminal,
re.escape(current_directory))
File "/usr/lib/python2.7/re.py", line 208, in escape
s = list(pattern)
TypeError: '__main__.NautilusVFSFile' object is not iterable
I'm sure I'm missing something obvious, but I supposed that
'current_directory' in get_background_items was simply... the current
directory. It turns out that it is a mysterious iterable object I wasn't
aware of.
Being a total noob, I'd like to know what this error means.
Thank you
