similar to :func:`pass_obj` but instead of passing the object of the
current context, it will find the innermost context of type
:func:`object_type`.
This generates a decorator that works roughly like this::
from functools import update_wrapper
def decorator(f):
@pass_context
def new_func(ctx, *args, **kwargs):
obj = ctx.find_object(object_type)
return ctx.invoke(f, obj, *args, **kwargs)
return update_wrapper(new_func, f)
return decorator
:param object_type: the type of the object to pass.
:param ensure: if set to `True`, a new object will be created and
remembered on the context if it's not there yet.

callback. This will also automatically attach all decorated
:func:`option`\s and :func:`argument`\s as parameters to the command.
The name of the command defaults to the name of the function. If you
want to change that, you can pass the intended name as the first
argument.
All keyword arguments are forwarded to the underlying command class.
Once decorated the function turns into a :class:`Command` instance
that can be invoked as a command line utility or be attached to a
command :class:`Group`.
:param name: the name of the command. This defaults to the function
name.
:param cls: the command class to instantiate. This defaults to
:class:`Command`.

printing out the version number. This is implemented as an eager
option that prints the version and exits the program in the callback.
:param version: the version number to show. If not provided Click
attempts an auto discovery via setuptools.
:param prog_name: the name of the program (defaults to autodetection)
:param message: custom message to show instead of the default
(``'%(prog)s, version %(version)s'``)
:param others: everything else is forwarded to :func:`option`.

this is added by default to all commands unless suppressed.

prints in the callback and exits.
All arguments are forwarded to :func:`option`.
