cli = DYMCommandCollection(sources=[cli1, cli2])

if __name__ == "__main__":
    cli()

Change configuration

There are two configuration for the DYMGroup and DYMCommandCollection:

@cli.group(cls=DYMGroup, max_suggestions=2, cutoff=0.7)
def cli():
    pass

... or ...

cli = DYMCommandCollection(sources=[cli1, cli2], max_suggestions=2, cutoff=0.7)
