I'm trying to autoexpand values as well as arguments using the builtin

I.E.
Consider the following command and arguments:

'Hello Georges !'
I can easily make 'tar' expand into 'target=' however I'd like to be
able to expand the value as well, choosing the target within a
predefined list. ie.
> sayHello target=<tab>
target=Georges target=Charles
However I have the feeling that cmd.Cmd consider the '=' character in
the way it will not try to expand anything beyond. When double tabbing
after the '=' it will print the list of available arguemnt (i.e
['target'] in the exemple above).
Ddd anyone successfuly expand values with cmd.Cmd ?
Some digging shows that your feeling is right:
http://docs.python.org/library/readline.html#readline.get_completer_delims
import readline
readline.get_completer_delims()
' \t\n`~!@#$%^&*()-=+[{]}\\|;:\'",<>/?'
After some initial problems with an extra space the following seems to work:
import cmd
import readline
class SayHello(cmd.Cmd):
def __init__(self):
cmd.Cmd.__init__(self)
delims = readline.get_completer_delims().replace("=", "")
readline.set_completer_delims(delims)
def do_sayHello(self, line):
print 'Hello %s !' % line.split('=')[1]
def complete_sayHello(self, text, line, begidx, endidx):
target_with_value = ["target=" + v for v in "Charles
Georges".split()]
commands = ["target", "tarpit", "anotherCmd"]
if text.startswith("target="):
return [c for c in target_with_value if c.startswith(text)]
completions = [c for c in commands if c.startswith(text)]
if completions == ["target"]: # avoid blank after target
return target_with_value
return completions
def do_EOF(self, line):
return True
if __name__ == '__main__':
SayHello().cmdloop()
Great ! Simple and effective. I didn't realize in the first place that
the completion was handled by readline.
