Python Nautilus Context Menu Extension

[MarekSkalicky]

I'm trying to create NFS sharing script and add simple Menu Item into nautilus context menu, with python-nautilus.

But the script seems to don't run. I've placed it into
/usr/lib/nautilus/extensions-2.0/python/ with chmod 755.


import os,nautilus,sys,re
sys.path.append("/usr/local/etc/nfss")
import NFS

class NFSSMenuScript(nautilus.MenuProvider):
def __init__(self):
self.nfss=NFS.NFSShare()
def get_file_items(self, window, files):
if len(files) != 1:
return
file=files[0]
items=[]
if file.is_directory():
if self.check_mount(file):
item = nautilus.MenuItem('NautilusPython::NFSShare_item_u mount', 'Umount NFS' ,'Umount file %s' % file.get_name())
item.connect("activate", self.menu_umount, file)
items.append(item)
return items
elif self.check_share(file):
item = nautilus.MenuItem('NautilusPython::NFSShare_item_m ount', 'Mount NFS' ,'Mount file %s' % file.get_name())
item.connect("activate", self.menu_mount, file)
items.append(item)
return items
else:
item = nautilus.MenuItem('NautilusPython::NFSShare_item_s hare', 'Share NFS' ,'Share file %s with NFS' % file.get_name())
item.connect("activate", self.menu_share, file)
items.append(item)
return items
else:
return
def menu_umount(self, menu, file):
self.nfss.Umount(file.get_uri())
def menu_mount(self, menu, file):
self.nfss.Mount(file.get_uri())
def menu_share(self, menu, file):
self.nfss.Share(file.get_uri())
def check_mount(self, file):
path=file.get_uri()
mount=self.nfss.network.GetMount()
for x in mount:
index=re.search(":/", x)
string=x[(index.start()+1):]
if path==string:
return 1
return 0

def DelMount(self, path):

del mount[index]
