Incremental programming language development

One of the well-known properties of software systems is that they are subject to changes. Incremental software development enables making such program changes in a non-destructive manner. In the area of programming language definition the language designer/implementer wants to include new language features incrementally as the programming language evolves. In the paper our approach to incremental programming language development is presented. The proposed approach has been successfully used in the development of real programming languages, which confirms feasibility in practice.
