iPOPO 0.5.8
===========

iPOPO v0.5.8 has been released !


What is iPOPO
=============

iPOPO is a Python-based Service-Oriented Component Model (SOCM) based on
Pelix, a dynamic service platform. They are inspired on two popular Java
technologies for the development of long-lived applications: the iPOJO
component model and the OSGi Service Platform.
iPOPO enables to conceive long-running and modular IT services.

It is based on OSGi concepts:
  - Bundle: a Python module imported using Pelix and associated to a
context. A bundle has a life-cycle (install, start, updated, stop,
uninstall)
  - Service: a Python object registered in a service registry, associated
to a specification and to properties.
  - Component: the instance of a class described/manipulated by iPOPO
decorators

Components are bound together by the specification(s) of the service(s)
they provide. The required services are injected into components by iPOPO.

iPOPO is released under the terms of Apache Software License 2.0


What's new in 0.5.8
===================

This version adds the "immediate_rebind" feature to iPOPO, and introduces
new variables in the Shell.
New features:
   The @Requires decorator has a new "immediate_rebind" flag argument,
which indicates iPOPO to not invalidate then re-validate a component if a
service can replace an unbound required one. See
https://github.com/tcalmant/ipopo/issues/25
    The shell now supports variables ("$var", "${var}", "$doted.var", …)
    A special variable, "$?" keeps the last non-None result of shell
commands
    Added the "run <file>" shell command to execute files as shell commands
