Hi All! The proposed Boost.Extension and Boost.Reflection libraries are back in active development, after a few months of inactivity. For those wishing to follow their progress, I am tracking the status of the libraries at: boost-extension.blogspot.com I've posted docs as well (also linked from the website): <tr_1202836009932>Boost.Extension docs<http://redshoelace.dlinkddns.com:9080/boost/doc/extension/index.html> The Reflection docs only have one useful section, detailing interoperability between Boost.Extension and Boost.Reflection: Reflection/Extension interoperability<http://redshoelace.dlinkddns.com:9080/boost/doc/reflection/boost_reflection/extension.html> It should contain enough information to show basic usage of the library. For more detailed code, you can look in the /test/ and /examples/ directories for both projects in the Subversion repository: http://svn.boost.org/trac/boost/browser/sandbox/libs/extension/ http://svn.boost.org/trac/boost/browser/sandbox/libs/reflection/ These libraries provide shared library (dll, so, dylib etc.) loading, and instantiation of classes in those libraries. Boost.Extension can load any class that inherits from a base class in the main module, whereas Boost.Reflection can load arbitrary classes. Feel free to try out the code in the sandbox. Current work: - Reflection documentation - Examples of using Extension with Boost.Functional/Factory - Advanced options for calling functions that have been reflected - calling functions when the function signature is unknown. If you have questions or feature requests, let me know. Thanks! Jeremy Pack boost-extension.blogspot.com
