SuppressCompleter is not working

[Dramelac]

Hello,

I try to disable the completer on some specific argument but using the SuppressCompleter completer doesn't work...

PoC code:

#!/usr/bin/env python
# PYTHON_ARGCOMPLETE_OK
import argparse
import argcomplete
from argcomplete.completers import SuppressCompleter

parser = argparse.ArgumentParser()

parser.add_argument("--mute").completer = SuppressCompleter

argcomplete.autocomplete(parser)
args = parser.parse_args()

When pressing TAB the default completer is still running by listing every files and directories.

Thank you for your help

Try instantiating the completer, i.e. SuppressCompleter().
