We have now a system available for testing and developing Ephedra. See details on the Ephedra pages.
The requirements for a typical piece of software change frequently, common
- changes in business rules or tax laws for a financial application,
- the need to make information available on the Internet,
- the extension of the software's life time,
- support for new hardware,
While some of these requirements can be implemented without major changes
of the overall design of the software, some do require massive restructuring,
or even source language conversion. Because of the size and complexity of
today's applications, this task usually cannot be performed manually but
only with tools that automate at least parts of the source code changes.
The goal of the Ovid project is to provide a tool collection to
support and facilitate software reengineering tasks. Rather than implementing
everything from scratch, we will collect existing open source tools and
tailor them to our needs.
The starting point for Ovid is Ephedra,
a C/C++ to Java source code transformation environment. Though its primary
focus was the transformation from C/C++ to Java, some of the source code
transformations it implements are general to be useful in a general
- Ephedra, Ovid's starting point.
- GXL, the language Ovid's various
components will use for data exchange.
- cppX, the C/C++ parser
we intend to use as a front-end.
- Rigi, a system for software
understanding in the large.
- IBM VisualAge C++,
Ephedra's current front-end.
