Frequently Asked Questions

General

How do you use circuits?

  • Have you read the website ?
  • Have you looked at the various examples ?

See: https://code.google.com/p/circuits/source/browse/#hg/examples

What is circuits ?

  • circuits is an event-driven framework with a high focus on Component architectures making your life as a software developer much easier
  • circuits allows you to write maintainable and scalable systems easily

Would you consider writing networking based programs using circuits versus Twisted matrix ?

  • YES absolutely. I always have.

Twisted (''to be perfectly honest'') is: * Complicated * Hard to understand * Not light weight

circuits is: * Simple * Consistent * Robust * Easy to understand * Very light weight.

GUI programming: Would circuits integrate with some GUI frameworks ?

  • This is definitely possible.
  • Currently I have no adapters for any GUI frameworks. but please feel free to write and submit a Component :)

What are the concepts behind circuits ?

a) Everything is a Component b) Components communicate by propagating Events

Also: * Components can be interlinked * Components are capable of managing their own Events and the Events of other Components.

How would you compare circuits to Twisted ?

  • circuits is simpler
  • circuits is maintainable
  • circuits has a nicer cleaner architecture: See [source:docs/graphs/ Dependency Graphs]
  • circuits is Component based.
  • circuits is purely 100% Event and asynchronous.

Can Components reside in different processes and talk to each others ?

  • YES
  • Currently in the works:
    • Process Component using the Python multiprocessing library.

Is there any restriction on the OS that circuits can run on ?

  • No. Although:
    • I only test on Linux and Mac OS X (''I don't have Windows to test on'').
  • Testers Welcome!

What version of Python does circuits work with ?

  • Currently circuits is tested with:
    • Python 2.5

Since circuits is an event-driven framework, how are you handling unit/integration tests ?

I'm lead to understand that unit-testing with event-driven software is often difficult if actually possible.

Are you using something akin to TwistedTrial ?

Are you running unit-tests across distributed test environments ?

  • circuits is not only a very good event-driven framework, but also a great Component framework.
  • Have a look at the [source:circuits/tests/ unit tests] that test the core of circuits.

Can circuits be used for concurrent or distributed programming ?

YES absolutely. See the [source:examples/primes.py Distributed Prime number finder]
