Lua/P – a repository language for flexible software engineering environments

Ongoing development and combination of methods and tools for software development call for software engineering environments (SEE) with ever changing functionality. Also the integration of operative support for the software development process remains a major challenge. A good SEE design has to combine a high level of integration with great flexibility towards evolving methods and tools as well as adaptability towards different kinds of development projects. We have developed PIROL as a generic SEE demonstrating that an executable meta model may play a key role in combining integration and flexibility. We coin the notion of a repository language to denote a domain specific language for the domain of repository based meta models. We introduce Lua/P as PIROL’s repository language with some non-standard properties and show how this language contributes to the desired properties of the environment
