The ironicclient.common.cliutils Module¶

exception ironicclient.common.cliutils.MissingArgs(missing)[source]¶

Bases: exceptions.Exception

Supplied arguments are not sufficient for calling a function.

ironicclient.common.cliutils.add_arg(func, *args, **kwargs)[source]¶

Bind CLI arguments to a shell.py do_foo function.

ironicclient.common.cliutils.arg(*args, **kwargs)[source]¶

Decorator for CLI args.

Example:

>>> @arg("name", help="Name of the new entity")
... def entity_create(args):
...     pass

ironicclient.common.cliutils.env(*args, **kwargs)[source]¶

ironicclient.common.cliutils.exit(msg='')[source]¶

ironicclient.common.cliutils.get_password(max_password_prompts=3)[source]¶

Read password from TTY.

ironicclient.common.cliutils.get_service_type(f)[source]¶

Retrieves service type from function.

ironicclient.common.cliutils.isunauthenticated(func)[source]¶

Checks if the function does not require authentication.

Mark such functions with the @unauthenticated decorator.

Returns:	bool

ironicclient.common.cliutils.pretty_choice_list(l)[source]¶

ironicclient.common.cliutils.print_dict(dct, dict_property='Property', wrap=0, dict_value='Value', json_flag=False)[source]¶

Print a dict as a table of two columns.

Parameters:	dct – dict to print dict_property – name of the first column wrap – wrapping for the second column dict_value – header label for the value (second) column json_flag – print dict as JSON instead of table

ironicclient.common.cliutils.print_list(objs, fields, formatters=None, sortby_index=0, mixed_case_fields=None, field_labels=None, json_flag=False)[source]¶

Print a list of objects or dict as a table, one row per object or dict.

Parameters:

objs – iterable of Resource fields – attributes that correspond to columns, in order formatters – dict of callables for field formatting sortby_index – index of the field for sorting table rows mixed_case_fields – fields corresponding to object attributes that have mixed case names (e.g., ‘serverId’) field_labels – Labels to use in the heading of the table, default to fields. json_flag – print the list as JSON instead of table

Usage:

@service_type('volume')
def mymethod(f):
...

ironicclient.common.cliutils.unauthenticated(func)[source]¶

Usage:

>>> @unauthenticated
... def mymethod(f):
...     pass

ironicclient.common.cliutils.validate_args(fn, *args, **kwargs)[source]¶

Check that the supplied args are sufficient for calling a function.

Traceback (most recent call last):
    ...
MissingArgs: Missing argument(s): a
>>> validate_args(lambda a, b, c, d: None, 0, c=1)

    ...
MissingArgs: Missing argument(s): b, d
