statez 0.1.2

Helps you to build fancy statemachines

statez

Motivation

All the statemachine packages for python look weird and do too much stuff. This one is simple (and synchronous).

Installation

pip install statez

# or if you use poetry
poetry add statez

Usage

from statez.core import (
    Trigger,
    From,
    To,
    Do,
    StateMachine,
    Event
)

if __name__ == '__main__':
    s = StateMachine("HungryBoi", state="hungry")
    transition = Trigger("Eat") | From(["hungry", "dunno"]) | To("not_hungry") | Do(lambda a: True)
    # It doesn't matter if you use the function directly or if you wrap it in Do :-)
    assert transition == Trigger("Eat") | From(["hungry", "dunno"]) | To("not_hungry") | (lambda a: True)
    s += transition
    s.consume(Event("Eat"))
    assert s.state == "not_hungry", s.state
