[Pythonmac-SIG] appscript with todos in iCal seams very slow

[Marcin Komorowski]

Hey All,

I am trying to generate a python internal structure (a dictionary of  
dictionaries) with a copy of all todo data from iCal.  I got it to  
work using the following code:

> #!/usr/bin/env /usr/bin/pythonw
>
> from appscript import *
> from sys import stdout
>
> appCal = app( 'iCal' )
> todos = appCal.calendars.filter(its.title != '').todos
>
> # Iterate flattened list, builing a local dictionary of  
> dictionaries, by uid
> local_tasks = {}
> for task in [ todo for cal in todos() for todo in cal ]:
>     uid = task.uid.get()
>     local_tasks[uid] = {
>             "completion_date" : task.completion_date.get(),
>             "due_date"        : task.due_date.get(),
>             "priority"        : task.priority.get(),
>             "sequence"        : task.sequence.get(),
>             "stamp_date"      : task.stamp_date.get(),
>             "summary"         : task.summary.get(),
>             "description"     : task.description.get(),
>             "uid"             : task.uid.get(),
>             "url"             : task.url.get(),
>         }
>     stdout.write('.')
>     stdout.flush()
>
> stdout.write('\n')
>
> print repr( local_tasks )
>
> stdout.write( "%d tasks\n" % len( local_tasks ) )

The problem is that this appears to execute painstakingly slowly.   
With 60 todo items in my iCal, the script takes just over 10 seconds  
to run.  My machine i a 2GHz Intel Core Duo iMac.

Any idea how this could be sped up?

Thank You,
Marcin
