A new version of EOS for Free Pascal 2.1.1. was released. It was tested on Linux with svn rev. 6222 of the bleeding edge Free Pascal compiler 2.1.1. No issues are reported. Unit tests with FPCUnit are included (they require the latest version of FPCUnit framework in the Free Pascal SVN).

With the port to Free Pascal we are now able to use EOS on FreeBSD. All the unit tests were passed using the cvs version of Free Pascal 1.9.3 on Linux and FreeBSD.

A first port to Free Pascal of the core features of EOS, a small framework written in Object Pascal that enables automatic XML serialization of business objects and it's easy linking to the GUI using the bridge pattern has been released.

To be able to test the code in the Extreme Programming style we also began a port to Free Pascal of the JUnit testing framework originally written in Java by Kent Beck and Erich Gamma. We are trying to adhere as much as possible to the original design, to preserve it's ease of use, so that testing could be done in the same manner as in the famous Java testing environment.
We think that the JUnit framework is worth studying on it's own, so the port of the code to Free Pascal is an unique occasion for us to learn the skills of programming with patterns and Test Driven Development from the code of two of the major experts in the field. ... read more

A new snapshot of the CVS is now available, including the framework for the link between the EOS Business Objects and the VCL/CLX controls.

You can find documentation about the project and the first ideas in the Wiki pages maintained by Uberto http://ubiland.freezope.org/camelos/.
The documentation is in Italian for now, translators needed ! :-)
