- update to 0.31.0:
* The typing hints introspection feature is automatically
enabled for any command (function) which does not have any
arguments specified via @arg decorator.
* A small change in the legacy argument mapping policy
BY_NAME_IF_HAS_DEFAULT concerning the order of variadic
positional vs. keyword-only arguments. The following function
now results in main alpha [args ...] beta instead of main
alpha beta [args ...]: def main(alpha, *args, beta): ...
This does not concern the default name mapping policy. Even
for the legacy one it's an edge case which is extremely
unlikely to appear in any real-life application.
* Added experimental support for basic typing hints (issue
#203) The following hints are currently supported: str, int,
float, bool (goes to type); list (affects nargs), list[T]
(first subtype goes into type); Literal[T1, T2, ...]
(interpreted as choices); Optional[T] AKA T | None (currently
interpreted as required=False for optional and nargs="?" for
positional arguments; likely to change in the future as use
cases accumulate). The exact interpretation of the type
hints is subject to change in the upcoming versions of Argh.
* Added always_flush argument to dispatch() (issue #145)
* High-level functions argh.dispatch_command() and
argh.dispatch_commands() now accept a new parameter
old_name_mapping_policy. The behaviour hasn't changed
because the parameter is True by default. It will change to
False in Argh v.0.33 or v.1.0.
