class ContextInheritingGroup(name=None, commands=None, **attrs)

Bases: Group

Subclass of click.Group whose children inherit its context_settings.

The group’s commands can be given different context settings by passing the context_settings keyword argument to command() and group() as normal.

New in version 1.1.0.

Methods:

command(*args, **kwargs)	A shortcut decorator for declaring and attaching a command to the group.
group(*args, **kwargs)	A shortcut decorator for declaring and attaching a group to the group.

command(*args, **kwargs)

A shortcut decorator for declaring and attaching a command to the group.

This takes the same arguments as click.command() but immediately registers the created command with this instance by calling into click.Group.add_command().

Return type

Callable[[Callable[…, Any]], Command]

group(*args, **kwargs)

A shortcut decorator for declaring and attaching a group to the group.

This takes the same arguments as click.group() but immediately registers the created group with this instance by calling into click.Group.add_command().

Return type

Callable[[Callable[…, Any]], Group]

class MarkdownHelpCommand

class MarkdownHelpGroup

Bases: MarkdownHelpMixin

Subclasses of click.Command and click.Group which treat the help text as markdown and print a rendered representation.

Tested in Gnome Terminal and Terminator (both libVTE-based), and PyCharm. libVTE has the best support. PyCharm’s support for italics and strikethrough is poor. Support on Windows is, as expected, poor.

Not tested on other terminals, but contributions are welcome to improve support.

New in version 0.8.0.

MarkdownHelpCommand.parse_args(ctx, args)

Parse the given arguments and modify the context as necessary.

Parameters

• ctx (Context)

• args (List[str])

Return type

List[str]
