wishbone 0.3.1

A Python library to write asynchronous event pipeline servers with minimal effort.

Latest Version: 0.4.10


A Python library to write asynchronous event pipeline servers with minimal effort.


The WishBone Python library offers a framework to write asynchronous event pipeline servers with minimal effort. In this context, event pipelines are best described as a collection of concurrently running modules which consume, process and produce events. Wishbone module queues are connected to one another forming a pipeline through which these events travel. Wishbone servers can be configured and controlled from from command line using bootstrap files. Bootstrap files allow to cherry-pick Wishbone modules and to define how events travel through them. Multiple identical Wishbone instances can run as separate processes offering parallel execution.


Through Pypi:

$ easy_install wishbone

Or the latest development branch from Github:

$ git clone

$ cd wishbone

$ sudo python install


Once Wishbone is installed you can try to execute it:

[smetj@indigo ~]$ wishbone
Wishbone version 0.1                                            Jelle Smet

The default Wisbone server.

/usr/bin/wisbhone command --config file [--instances number] [--loglevel level]
[--pid filename] [--group groupname]


            start           Starts and daemonizes the program into the background.
            stop            Stops a daemonized instance.
            debug           Starts the program in the foreground without detaching.
            kill            Kills the daemonized instance.
            list            Lists the available Wishbone modules in group


            --config        The filename of the bootstrap config file.

            --instances     The number of parallel instances to start. Default is 1.

            --loglevel      Defines the loglevel to use. Default is "info".
                            Possible values are:
                                info, warning, critical, debug

            --pid           Defines the location of the pidfile.
                            The default value is /tmp/

            --group         The name of the module group to list modules from.
