Presets

`duho.presets`

Pre-configured argument classes for common patterns.

Bases: Args

Args subclass with built-in --verbose and --loglevel support.

Set a class attr _version_ to opt into a --version flag; no separate preset class is needed::

class MyApp(LoggingArgs):
    _version_ = "1.2.3"

--version prints "%(prog)s 1.2.3" and exits 0. It is skipped if a version-dest action already exists (e.g. supplied by a parent parser).

Log Levels

Quiet level

Verbose level
