Till now development of a new software language is far too often an artistic handwork and reminds us on the state of software development from 50 years ago.

To apply the “engineering” as a systematic methodological approach to software language definitions, we address several outstanding topics, such as lack of semantics, language libraries, compositionality, extensibility and variant management in languages and their tools. We also examine the state of the art and discuss possible solutions.
