Introducing License Enforcement in Socket
Ensure open-source compliance with Socket’s License Enforcement Beta. Set up your License Policy and secure your software!
A small, simple, and fast framework for reactive programming
Before anything else make sure you read and agree with the license.
Available through pip
:
pip install jfaleiro.reactives
or poetry
:
poetry add jfaleiro.reactives
Reactives allow for three types of bindings: pre
, post
, and notify
.
pre
bindings - a chain of calls executed synchronously and in sequence before an update on state is performed. For R
reactives, the value of the last execution on pre-binding chain is kept. Special shortcuts:
guard
- used to establish boolean conditions for a change in state to fail.post
bindings - a chain of calls executed synchronously and in sequence after an update on state is performed. For synchronous notification purposes. Exceptions and updates are ignored.
notify
bindings - a chain of calls executed asynchronously and after the last post
call is performed. For asynchronous notification purposes. Exceptions and updates are ignored
with Context() as x:
a = x.new(R, 1)
b = x.new(R, 2)
c = a + b
assert a.value == 1
assert b.value == 2
assert c.value == 3
a.pre(guard(lambda x: x > 0))
c.pre(guard(lambda x: x >= 3))
a.value = 4
assert a.value == 4
assert b.value == 2
assert c.value == 6
Look for plenty of examples of use under ./tests
as well as Jupyter notebooks on ./samples
for interactive use.
Enjoy.
