Render Event human readable name #600
Description
Event has human readable name, but graph labels do not use it. Is it possible to fix it?
from statemachine import StateMachine, State, Event
from statemachine.contrib.diagram import DotGraphMachine
class ExampleStateMachine(StateMachine):
active = State(name='Active Human Text', initial=True)
suspended = State(name='Suspended Human Text', final=True)
suspend = Event(
active.to(suspended),
name="Human Suspend",
)
graph_machine = DotGraphMachine(ExampleStateMachine)
g = graph_machine()
g.write_png('example.png')
Thank you for this nice library!

fix: render human-readable Event name in diagrams (#600)

Thanks for reporting this and for the kind words about the library!
This is now fixed in #601 —
Event.nameis auto-humanized from theid(e.g.,suspend→Suspend,pick_up→Pick up), and explicitname=values are preserved as expected. Diagrams, Mermaid output, and text tables all use the human-readable name now.This should land in the next release.
