Use State Mate from Python¶

State Mate exposes the same two-stage workflow used by the CLI: load a Sismic statechart, then render it.

from state_mate import load_statechart, render

statechart = load_statechart("examples/order.yaml")
source = render(statechart)

print(source)

Write generated source yourself¶

from pathlib import Path

from state_mate import load_statechart, render

statechart = load_statechart("examples/order.yaml")
Path("build/order_machine.py").write_text(
    render(statechart),
    encoding="utf-8",
)

Validate an existing Sismic model¶

If another part of your application already produced a sismic.model.Statechart, call the subset validator directly:

from state_mate import validate_supported_subset

validate_supported_subset(statechart)

This avoids reloading or translating the model. State Mate deliberately operates on Sismic's own objects.
