Attributes Documentation

human_readable_name

Returns the human readable name of this parameter. This is the same as the name for options, but the metavar for arguments.

param_type_name = 'argument'

Methods Documentation

add_to_parser(parser, ctx)

consume_value(ctx, opts)

full_process_value(ctx, value)

get_default(ctx)

Given a context variable this calculates the default value.

get_error_hint(ctx)

Get a stringified version of the param for use in error messages to indicate which param caused the error.

get_help_record(ctx)

get_usage_pieces(ctx)

handle_parse_result(ctx, opts, args)

make_metavar()

Overrides click.Option.make_metavar. Makes the metavar for the help menu. Always adds a space and an elipsis (’ …’) after the metavar name if the option accepts multiple inputs.

By default click adds an elipsis without a space between the metavar and the elipsis, but we prefer a space between.

Returns:

metavar : str

The metavar value.

process_value(ctx, value)

Given a value and context this runs the logic to convert the value as necessary.

resolve_envvar_value(ctx)

type_cast_value(ctx, value)

Given a value this runs it properly through the type system. This automatically handles things like nargs and multiple as well as composite types.
