Hi Jim,
That "illustrate" example is often helpful if you get lost in the calls.
Good to hear you are clear on what is happening.

Hi Richard,
I see what is going on with this now. Here's the example that had me stumpped.
All it is doing is printing messages that prove that the override functions
work, then it's calling the default versions from the cmd module itself. I was
thinking way too much.
import cmd
class Illustrate(cmd.Cmd):
"Illustrate the base class method use."
def cmdloop(self, intro=None):
print 'cmdloop(%s)' % intro
return cmd.Cmd.cmdloop(self, intro)
def preloop(self):
print 'preloop()'
def postloop(self):
print 'postloop()'
def parseline(self, line):
print 'parseline(%s) =>' % line,
ret = cmd.Cmd.parseline(self, line)
print ret
return ret
def onecmd(self, s):
print 'onecmd(%s)' % s
return cmd.Cmd.onecmd(self, s)
def emptyline(self):
print 'emptyline()'
return cmd.Cmd.emptyline(self)
def default(self, line):
print 'default(%s)' % line
return cmd.Cmd.default(self, line)
def precmd(self, line):
print 'precmd(%s)' % line
return cmd.Cmd.precmd(self, line)
def postcmd(self, stop, line):
print 'postcmd(%s, %s)' % (stop, line)
return cmd.Cmd.postcmd(self, stop, line)
def do_greet(self, line):
print 'hello,', line
def do_EOF(self, line):
"Exit"
return True
if __name__ == '__main__':
Illustrate().cmdloop('Illustrating the methods of cmd.Cmd')
