Announcing XOTcl 1.3.5 ********************** WHAT IS XOTCL? XOTcl is an object-oriented extension of Tcl that was derived from OTcl. In short, XOTcl tries to provide a highly flexible, reflective, component-based, and object-oriented environment. It integrates language support for high level concepts which are not found in other languages, with reasonable performance. It prevails the Tcl programming style and the dynamic/introspective nature of the language, rather than introducing other language's styles and rigidness (such as C++) into Tcl. Major changes relative to 1.3.4 are: - Qualitative Improvements * Improved code quality: + fixed possible segmentation violations in non positional argument handling + moved the Serializer into a namespace such that % package req XOTcl % package req xotcl::serializer Serialize .... works without namespace imports (the Serializer is still auto-exported, but this will change in the future) + * Improved Functionality + Non-positional arguments can be used in the same argument list as positional ones (more compliant with OpenACS). One can write now % Object o % o proc foo {-x:boolean -y a b} { ...} instead of % ... % o proc foo {-x:boolean -y} {a b} { ...} All introspection commands will work like before. The old syntax (with the additional argument) is deprecated and will be dropped in the future. + Serializer: support for objects with parent namespaces, which are not xotcl objects + additional instproc for ::xotcl::Class allinstances to return all instances for the actual class For more details about the changes, please consult the ChangeLog and documentation.
