示例1: extended_help_option
# 需要導入模塊: import click [as 別名]
# 或者: from click import help_option [as 別名]
def extended_help_option(extended_help=None, *param_decls, **attrs):
"""
Based on the click.help_option code.
Adds a ``--extended-help`` option which immediately ends the program
printing out the extended extended-help page. Defaults to using the
callback's doc string, but can be given an explicit value as well.
This is intended for use as a decorator on a command to provide a 3rd level
of help verbosity suitable for use as a manpage (though not formatted as such explicitly).
Like :func:`version_option`, this is implemented as eager option that
prints in the callback and exits.
All arguments are forwarded to :func:`option`.
