<h2 id="overview">Overview</h2>
<p>
C-Pluff is a plug-in framework for C programs.
It has been strongly inspired by the Java plug-in framework in
<a href="http://www.eclipse.org/">Eclipse</a>. C-Pluff focuses on
providing core services for plug-in interaction and plug-in
management. It aims to be platform neutral and supports dynamic
changes to plug-in configuration without stopping the whole
application or framework. It does not yet provide special facilities
for distribution such as signed plug-in packages or remote plug-in
repositories but it is possible to build such features on top of the
current framework.
</p>
<p>
The current C-Pluff implementation and documentation is very much
work in progress so it should be considered early alpha stage software.
I will be updating the documentation and source distribution on this
site as I proceed with documentation and implementation.
If you are interested in C-Pluff, take a look at
<a href="reference/c-api/index.html">reference documentation</a>,
join <a href="http://www.c-pluff.org/lists">mailing lists</a> or
<a href="http://www.c-pluff.org/download">download it</a>. You can also send
feedback, ideas and thoughts about such platform directly to the
<a href="mailto:johannes.lehtinen@iki.fi">author</a>.
</p>
<h2 id="structure">Architecture</h2>
<p>
The plug-in architecture supported by C-Pluff is presented in the
following figure. There is a thin main program controlling the plug-in
framework. The main program is responsible for initializing and setting
up the plug-in environment. Most of the application logic is contained in
plug-ins which are independent components and can be developed and
distributed separately. Plug-ins integrate with each other by providing
extension points and extensions. An extension point is a point into which
other plug-ins can attach extensions. An extension can be just
information, expressed in XML format, or the plug-in may also provide
program logic as part of the plug-in runtime library. The framework
provides services for accessing extensions and for managing plug-in
dependencies.
