It's OK, but now that I've got the ILU interface to Python (in
alpha-test at PARC -- thanks, Denis), and Python Tk (still in a state of
flux, but already useful), and mongo amount of stuff already in Python
(check out ftp://ftp.eeel.nist.gov/pub/python/dbhash.tar.gz for a nice
implementation of general hashing with stable storage, much nicer
properties than the standard dbm module), I don't see much sense in
using anything but Python for prototyping. And final products, for that
matter.

Note that the Tk canvas widget was stolen (with attribution) from Joel
Bartlett's ezd, which is even neater (see
ftp://gatekeeper.dec.com/pub/DEC/ezd/techreport.psf.Z, which is a
compressed Postscript file). The emerging Python Tk is gradually
eliminating all traces of Tcl -- everything's done in Python.
As a teaser, here's the Python code to find and return a Calendar
Manager object, via ILU, to manipulate the SunOS CM:
# module findCM -- find a calendar manager
pm = {}
def findCM(machine='localhost'):
import PortMapper # ILU interface to Sun portmapper
import CalendarManager # ILU interface to Sun CM
global pm
if not pm.has_key(machine):
# instantiate portmapper object on machine "machine"
pm[machine] = PortMapper.T('0@'+machine+'_PortMapper@sunrpc_100000_2|tcp_'+machine+'_111', None)
cm_spec = {'port': 0, 'prog': 100068, 'vers': 3, 'prot': PortMapper.UDP_Protocol}
# ask the portmapper what port the calendar manager is using
cm_port = pm[machine].GetPort (cm_spec)
if (cm_port == 0):
raise NoCalendarManager, cm_spec
# instantiate the CM
return CalendarManager.CM('0@'+machine+'_CalendarManager@sunrpc_100068_3|udp_'+machine+'_'+str(cm_port), None)
# end of module findCM
