[Sugar-devel] Sugar-devel Digest, Vol 63, Issue 73

[Tony Anderson]

Hi,

The original sugar-launch intended to provide this capability. It 
requires only
a few lines of code.

parser.add_option("-o","--object_id",action="store_true",dest="object_id",
                   help="resume activity with object")
parser.add_option("-u","--object_uri",action="store_true",dest="object_uri",
                   help="path to file")

adds the -o and -u option. In practice, I use the -o option.

if options.object_id:
     cmd_args.append("-o")
     cmd_args.append(args[1])
if options.object_uri:
     cmd_args.append("-u")
     cmd_args.append(args[1])

added after the if options.debug sets the option at launch.
