When programmers copy, paste, and then modify source code, the once-identical code fragments (code clones) can become indistinguishable as the software evolves over time. In this paper, we present three features of our software tool, a set of Eclipse plug-ins named CnP (CnP's clone visualization, CReN, and LexId), which aids the programmer during copy-and-paste programming. We believe that the clone-awareness...
Copying and pasting source code results in code duplication. A common form of software reuse involves modifying the new duplicate to fit a current task. The similar code fragments (code clones) may be edited inconsistently by the programmer, for various reasons, leaving a bug in the software that may remain undetected by both the programmer and the compiler. A previously published tool, CReN, helps...
The life cycle of software applications in general is very short and with extreme volatile requirements. Within these conditions programmers need development tools and techniques with an extreme level of productivity. We consider the code reuse as the most prominent approach to solve that problem. Our proposal uses the advantages provided by the Aspect-Oriented Programming in order to build a reusable...
Pointcut fragility is a well-documented problem in Aspect-Oriented Programming; changes to the base-code can lead to join points incorrectly falling in or out of the scope of pointcuts. We present an automated approach that limits fragility problems by providing mechanical assistance in pointcut maintenance. The approach is based on harnessing arbitrarily deep structural commonalities between program...
Back in 2001, the MIT announced aspect-oriented programming as a key technology in the next 10 years. Nowadays, 8 years later, AOP is not widely adopted. Several reasons can explain this distrust in front of AOP, and one of them is the lack of robust tools for analysis, testing and maintenance. In order to develop dedicated solutions for assisting the development with AOP, and increase its adoption,...
The FermaT Maintenance Environment (FME) is a platform independent graphical user interface for the FermaT program transformation system. It is able to represent WSL code and apply FermaT transformations on single statements.
Java 5 has introduced a number of new syntactical language features that make development faster, easier, and safer. However, at the same time, it has also introduced downward incompatibilities: code written for Java 5 cannot be used on pre-Java 5 platforms. This tool demonstration presents a number of source-to-source transformations that backport source code written for the Java 5 platform to legacy...
