Simpl DSL toolkit

This paper describes LDTA tool challenge entry that is implemented using Simpl DSL toolkit. Simpl is targeted at enterprise software development, helping to create DSL implementations that can be embedded into other systems. Simpl builds up on top of existing tools and programming languages and adds: a simple language for grammar descriptions that can be used to generate both the parser and the data types for representing abstract syntax trees; a pretty-printing library; an IDE framework; and integration layer that combines all components into a single whole and minimizes the need for boilerplate code.When implementing the challenge, Simpl provided direct support for parsing and code generation tasks. Name and type checking were implemented in Scala. In addition to the challenge task, Simpl was used to create an Eclipse-based IDE for the target language.
