Simpl is a tool for quickly and efficiently implementing domain-specific languages. Its main target is enterprise information systems. The main design criteria of the Simpl toolset are the following.

  • Visual (editor, IDE) and non-visual (parser, code generator) parts of a DSL implementation must be separate. The non-visual part does not depend on the visual part.
  • Non-visual part of the DSL implementation is easily integrable into larger systems and does not make assumptions on how the larger system is implemented.
  • Using Simpl, the language developer must be able to create a working DSL implementation with little effort. For a relatively simple language, the time to create a working code generator and an IDE should be less than a day.

Based on these design criteria, the Simpl builds on existing tools by combining them and creating a user-friendly frontend. In particular, Simpl is based on the following tools:

  • ANTLR parser generator,
  • Eclipse IDE,
  • IDE Meta-Toling Platform (IMP),
  • Scala programming language.

Simpl is developed in Cybernetica AS and Software Technology and Applications Competence Centre. It is licenced under GNU Lesser General Public License.
