Functions

mk_str_attr_obj(iterable[, name, trans])	Make an object with given string attributes.
target_instance_checker(*target_types)	Returns a function that checks if an object is an instance of any of the target_types

doodad.util.mk_str_attr_obj(iterable, name=None, trans=None)

Make an object with given string attributes.

The purpose of this function is to offer a different option to having to write strings in code when specifying a string value when this value should only be taken from a fixed set of values, and use tab completion to see the available values.

Parameters:

• iterable (Iterable) – an iterable of strings (or a space separate string)

• name (str) – the name of the namedtuple

>>> f = mk_str_attr_obj('date worker offre success')
>>> f.date
'date'
>>> f.worker
'worker'
>>> f.does_not_exist
Traceback (most recent call last):
...
AttributeError: 'AttrObj' object has no attribute 'does_not_exist'

f is a namedtuple so you can do things like:

>>> list(f)
['date', 'worker', 'offre', 'success']
>>> date, worker, offer, success = f
>>> offer
'offre'

doodad.util.target_instance_checker(*target_types)

Returns a function that checks if an object is an instance of any of the target_types
