annotattrs 0.0.12

annot_attrs (current v0.0.12/)
DESCRIPTION_SHORT
work with annotated but not defined/not used attrs in class

Designed to get list of annotated but not defined/not used attrs from class (not instance!).
may be helpful further in instance to check that really have values.
Features

get set of unused attributes from class(not instance!)
work with nested classes
get values:

by case insensitive names
by dict key access method

work on any object (over Obj parameter!):

1. example1.py
# ===============================================================
### 1. inheritance
# (BEST practice - dont mess classes! use as separated object!)
from annot_attrs import *

class Cls:
ATTR1: int
ATTR2: int = 2

obj = Cls(1)

assert AnnotAttrs().annots_get_set(obj) == {"ATTR1", }
assert AnnotAttrs().annots_get_dict(obj) == {"ATTR1": 1, }

# ===============================================================
from annot_attrs import *

class Cls(AnnotAttrs):
ATTR1: int
ATTR2: int = 2

assert Cls().annots_get_set() == {"ATTR1", }

class Cls2(Cls):
ATTR1: int = 2

### 2. Indepandant usage
from annot_attrs import *

try:
class Cls(AnnotAttrs, NamedTuple):
ATTR1: int
ATTR2: int = 2
except TypeError:
# TypeError: can only inherit from a NamedTuple type and Generic
pass
else:
assert True

ATTR1: int
ATTR2: int = 2

obj = Cls(1)
assert AnnotAttrs().annots_get_set(obj) == {"ATTR1", }
assert AnnotAttrs().annots_get_dict(obj) == {"ATTR1": 1}
