Blinker Documentation

Blinker provides fast & simple object-to-object and broadcast signaling for Python objects.

The core of Blinker is quite small but provides powerful features:

  • a global registry of named signals
  • anonymous signals
  • custom name registries
  • permanently or temporarily connected receivers
  • automatically disconnected receivers via weak referencing
  • sending arbitrary data payloads
  • collecting return values from signal receivers


Python 2.4 or later; Python 3.0 or later; or Jython 2.5 or later.

No other modules are required.
