Language Definition and Extension with MPS
Abstract
Language definition and extension is a hot topic. Using modular
languages, where a program can use concepts from different language
modules as needed, promises significantly increased language usability as
well as an integration between general purpose (programming) and
domain-specific (modeling) concepts and tools.
JetBrains MPS is an open source language workbench that uses projectional
editing as opposed to parsing techniques. In MPS, languages are defined
via structure, projection rules, transformation rules and type systems.
In this tutorial I will provide a brief overview about how MPS works and
what you can do with it. I will show how to build an external DSL, how to
integrate the external DSL with Java, and how to extend an existing
programming language with a new statement. To round it off, I will demo
a non-trivial set of languages for embedded software development. 90% of
the tutorial will be live demos.
Note that even if you don't plan to work with MPS specifically, this tutorial
will provide a good overview of projectional editing.
