reacttrs
Reactive attributes, initially extracted out from Textual, now a fork of Declare.
from reacttrs import Int, Str
class Foo:
name = Str("Paul")
age = Int(34)
birth = Int(1990)
@name.watch
def _watch_name(self, old: str, new: str):
print(f"{old=}, {new=}")
@age.validate
def _validate_age(self, value: int) -> int:
return 2024 - self.birth
foo = Foo()
foo.name = "John" # old='Paul', new='John'
foo.name = "Steve" # old='John', new='Steve'
print(foo.age) # 34
foo.birth = 1991
foo.age = 34
print(foo.age) # 33
