The review of the Egg library by Shunsuke Sogame starts today.The library is concerned with the implementation and adaptation of function objects. As function objects are everywhere in Boost and C++, I hope to see plenty of discussion and votes during the review. Introduction: It is not so easy to define Function Objects especially if you want to support Boost.ResultOf and Boost.Lambda. Therefore, as Boost provides iterator_facade and iterator adaptors, Egg provides function_facade and function adaptors. Egg provides the following features: * Workaround for the Forwarding Problem http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1385.htm * Helpers to build Function Objects: * egg::function and egg::function_facade provides the way to build Function Objects which supports Boost.ResultOf and Lambda. * Function Objects Adaptors(in other words, higher-order functions): * egg::curryN supports the currying. * egg::pipable emulates extension methods(C#). * egg::fuse/unfuse emulates variadic functions. * egg::nestN represents nested lambda expressions. * etc... The documentation is on line: http://p-stade.sourceforge.net/boost/libs/egg/ The zipped source code is in Vault/FunctionObjects: http://tinyurl.com/34lgda Tested under: Boost Development Trunk and Boost Version1.34.1. --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?
